IMPORTANT INFORMATION ON THE GRAFTON™ AND GRAFTON PLUS™
DEMINERALIZED BONE MATRIX (DBM)

Note: not all parts may be available in each geography

READ BEFORE USE

This graft is derived from human tissue which was generously donated so others may benefit.
Each unit is intended for single patient, single use only.
Caution: restricted to use by a physician or dentist.
No additional sterilization step is to be performed.

DESCRIPTION

Grafton™ DBM and Grafton Plus™ DBM contain demineralized human bone tissue combined with an inert additive to yield a
demineralized bone matrix (DBM) allograft product having a particular physical form and/or handling property. Grafton™ DBM
Gel and Grafton Plus™ DBM Paste are produced from a powder form of DBM, while Grafton DBM Flex , Putty, Matrix,
Crunch™ and Orthoblend are produced from a fiber form of DBM. Grafton™ DBM Crunch™ also contains demineralized bone
chips/cubes, while Grafton DBM Orthoblend contains non-demineralized cancellous bone chips in addition to the DBM.
Grafton™ DBM and Grafton Plus™ DBM are malleable and can be molded or cut into various sizes and shapes according to
the intended implant site.

DBM allograft was prepared from human bone tissue recovered from a cadaveric donor using aseptic surgical techniques and
was microbiologically tested during recovery. The tissue was further processed under aseptic conditions and treated with
antibiotics (gentamicin), cleaned using 70% alcohol, washed with purified water, and sonicated. This allograft may also have
been processed with an additional surfactant. Subsequent demineralization of the bone tissue (using the D-MIN™ proprietary
demineralization process) to produce the DBM in this product was performed so the resulting bone matrix has a calcium content
level that meets current American Association of Tissue Banks (AATB) standards . The demineralized bone matrix (along with
the cancellous bone chips for Grafton™ DBM Orthoblend) was combined with USP anhydrous glycerol (Grafton DBM allografts)
or a starch carrier (Grafton Plus™ DBM allografts) to form the final allograft product. The final product in packaged form was
tested for sterility according to procedures in the current U.S. Pharmacopoeia, tested for endotoxins using a qualified test
method, and exported from the USA.

Grafton™ DBM and Grafton Plus™ DBM are demineralized bone allograft products that are osteoconductive as well as
osteoinductive in an athymic rat assay.

Grafton™ DBM and Grafton Plus™ DBM are prepared via a proprietary processing method of Medtronic validated to
consistently produce DBM that is osteoinductive in an athymic rat assay. Product and process consistency are confirmed via
ongoing testing of Grafton™ DBM and Grafton Plus™ DBM finished product for osteoinductivity in this validated athymic rat
assay using a five-point linear scale (0,1,2,3,4) to score bone formation at 28 days post implantation*. This bone forming activity
exhibited by Grafton™ DBM and Grafton Plus™ DBM in this athymic rat surrogate assay should not be interpreted as a
predictor of clinical performance.

The device lifetime for Grafton™ Plus DBM, and Orthoblend is two years in which it is expected to achieve its performance and
maintain its safety.

The device lifetime for Grafton™ DBM Flex, Grafton™ DBM Crunch, Grafton™ DBM Putty, Grafton™ DBM Gel, and Grafton™
DBM Matrix is three years in which it is expected to achieve its performance and maintain its safety.

VIRAL INACTIVATION PROCEDURES

DBM in Grafton™ DBM and Grafton Plus™ DBM is produced by a proprietary production process validated to inactivate viruses
including HIV-1, hepatitis B (duck hepatitis virus as model), hepatitis C (bovine diarrhea virus as model), CMV, and Polio.†
Testing was performed according to the current concepts and study design elements for process validation studies for the
removal and/or inactivation of viruses in the production of biopharmaceutical products recommended by the Food and Drug

Administration’s (FDA) Center for Biologics Evaluation and Research
were performed in certified conformity with Good Laboratory Practice for Nonclinical Laboratory Studies regulations stated in the
Code of Federal Regulations (21 CFR § 58).

These viral inactivation procedures were used to further reduce the risk of disease transmission via the use of Grafton™ DBM
and Grafton Plus™ DBM allografts beyond the protection provided by donor testing and screening procedures.

The process used to produce the non-demineralized cancellous bone chips in Grafton™ DBM Orthoblend does not afford the
same degree of viral inactivation as the process used to produce the DBM. However, the risk of disease transmission with this
tissue component remains low due to multiple safeguards rigorously employed, including donor screening, laboratory testing,
and material processing.

INDICATIONS FOR USE

Grafton™ DBM and Grafton Plus™ DBM are intended for use as a bone graft extender, bone graft substitute, and bone void
filler in bony voids or gaps of the skeletal system (i.e. spine, pelvis, and extremities) not intrinsic to the stability of the bony
structure. The voids or gaps may be surgically created defects or defects created by traumatic injury to the bone.

Grafton™ DBM (excluding the Orthoblend form) and GraftonPlus™ DBM are also intended to be packed into bony voids or
gaps to fill and/or augment dental intraosseous, oral, and cranio-/maxillofacial defects. These defects may be surgically created
osseous defects or osseous defects created from traumatic injury to the bone, including periodontal/infrabony defects; alveolar
ridge augmentation (sinusotomy, osteotomy, cystectomy), dental extraction sites (ridge maintenance, implant preparation/
placement), sinus lifts, cystic defects, and/or craniofacial augmentation. Grafton™ DBM and Grafton Plus™ DBM may be used
alone in a manner comparable to autogenous bone chips or allograft bone particulate (demineralized freeze dried bone), or they
may be mixed with either allograft or autograft bone or bone marrow as a bone graft extender. Grafton™ DBM and Grafton
Plus™ DBM are indicated only for bony voids or gaps not intrinsic to the stability of the bony structure.

Grafton™ DBM and Grafton Plus™ DBM are absorbed/remodeled and replaced by host bone during the healing process.

Note: consider that Grafton™ DBM Crunch™ contains demineralized bone chips approximately 3 mm (±1 mm) when
determining the appropriateness of this allograft for use in small defects.

CONTRAINDICATIONS

▪ Presence of infection at the transplantation site.
▪ Treatment of spinal insufficiency fractures.

CAUTION

This allograft may contain trace amounts of antibiotics (gentamicin), surfactant, and other processing solutions. Caution should
be exercised if the patient is allergic to these antibiotics or chemicals.

Grafton Plus™ DBM Paste contains starch. Therefore, caution should be exercised when using Grafton Plus™ DBM Paste in a
patient with a starch allergy and/or amylase deficiency.

PRECAUTIONS

Extensive donor blood serum testing, medical and social history screening procedures, and tissue microbiological testing were
used in the qualification of tissue donors. Despite viral inactivation, extensive tissue donor selection, and qualification processes
used in providing this tissue graft, transmission of infectious disease through the use of this tissue graft is still possible. Bacterial
infection at the graft site may also occur. Adverse outcomes potentially attributable to Grafton™ DBM or Grafton Plus™ DBM
must be reported promptly to Medtronic.

Adequate fixation should be used to stabilize the implant site during bone formation and healing in bony voids or gaps of the
skeletal system (i.e. spine, pelvis, and extremities).

If injecting Grafton™ DBM or Grafton Plus™ DBM into the defect site, take precaution not to:

▪ Over-pressurize the delivery device, as this may lead to extrusion of the device beyond the site of its intended application

and damage to the surrounding tissues.

▪ Over-pressurize the defect site, as this may lead to fat embolization or embolization of the device material into the

bloodstream.

When used as a bone graft extender in bony voids or gaps of the skeletal system (i.e., spine, pelvis, and extremities), Grafton
Plus™ DBM Paste is intended for use only with autograft, not other allograft. Recommended ratios of Grafton Plus™ DBM
Paste to autograft as a bone graft extender are 1:1 or 2:1.

DONOR SCREENING AND TESTING

Prior to donation, the donor’s blood, tissues, and medical/social history were screened for medical conditions or disease
processes that would contraindicate the donation of tissues in accordance with current FDA regulations and standards
established by the AATB. The donor’s medical/social history was also screened for HIV, Hepatitis, and CJD/vCJD high risk
factors in accordance with current US Public Health Service recommendations and FDA regulations and guidance documents.

Testing of donor blood and tissue samples began at the site of recovery and continued into processing. Donor blood samples
taken at the time of recovery were tested for communicable disease by a laboratory registered with the FDA to perform donor
testing and certified to perform such testing on human specimens under the Clinical Laboratory Improvement Amendments of
1988 (CLIA) (42 U.S.C. 263a) and 42 CFR Part 493 using FDA approved, licensed, or cleared tests including:

▪ HbsAg Hepatitis B Surface Antigen
▪ HBc-IgM/IgG Hepatitis B Total Core Antibody
▪ HCV Hepatitis C Antibody
▪ HIV 1/2-Ab Antibody to Human Immunodeficiency Virus Types 1 and 2
▪ HIV 1 NAT Human immunodeficiency virus type 1 nucleic acid amplification testing
▪ HCV NAT Hepatitis C virus nucleic acid amplification testing

The results of all the relevant communicable disease tests referenced were found to be negative or non-reactive.
In addition to the tests listed, other tests may have been performed including tests for HBV NAT (Hepatitis B virus NAT) and

WNV NAT (West Nile Virus NAT). If HBV NAT and WNV NAT were performed, the results were negative or non-reactive, and
the results of any other tests performed were negative or otherwise acceptable for eligibility of donors of musculoskeletal
tissues.

The communicable disease test results, together with the informed consent, medical and social history interview, physical
assessment, available medical records (to include previous medical history, laboratory test results, autopsy and coroner reports,
if performed), and information obtained from any source or records which may pertain to donor eligibility were evaluated. Based
on this evaluation, the donor met donor eligibility criteria current at the time of recovery. Donor eligibility criteria used to screen
this donor are in compliance with FDA regulations published in Part 1271 “Human Cells, Tissues, and Cellular and Tissue­Based Products”, as applicable.

Donor eligibility was determined by one of the following tissue banks:
American Tissue Services Foundation

Surprise, AZ 85378
Community Tissue Services

Dayton, OH 45402
LifeNet Health

Virginia Beach, VA 23453
RTI Surgical, Inc.

Alachua, FL 32615
Names and addresses of the testing laboratories, the listing and interpretation of all required communicable disease tests, a

listing of the documents reviewed as part of the relevant medical records, and the name of the person or establishment
determining the eligibility of this human tissue are on file at Medtronic, Eatontown, NJ and are available upon request.

The final processed tissue allograft product was released by Medtronic based on the initial donor eligibility determination and on
a post-processing review and determination that the product met all processing requirements and specifications.

This tissue allograft product was released for transplantation.

STERILITY

Grafton™ DBM and Grafton Plus™ DBM tissue allograft products were aseptically processed and tested for sterility, as
indicated by the package label.

Tissue allografts labeled as “Aseptically Processed, Passes USP Sterility Tests” or “Sterile” were aseptically processed and
tested for sterility according to the procedures in the current US Pharmacopeia.

Medtronic may use low dose gamma irradiation as an adjunct to aseptic processing to reduce bioburden. Grafton™ DBM and
Grafton Plus™ DBM package labels containing “Tissue Gamma Irradiated” indicate low dose (1.0 – 1.8 Mrad) gamma
irradiation was used as a means of reducing the bioburden on the donor tissue.

When explanting and/or disposing of a device, be sure to avoid exposure to bodily substances such as blood, tissue, etc., as
contact could lead to infection or disease. Always wear and use proper equipment, taking special care with sharp objects and
needles. Follow your healthcare center’s policy regarding both the disposal of devices and any events of exposure.

TISSUE TRACKING

Federal (USA) regulations under 21 CFR 1271 establish requirements for tracking human tissue products. In accordance with
these regulations, the package label of each Grafton™ DBM and Grafton Plus™ DBM unit distributed by Medtronic bears a lot
number that serves as a distinct identification code recorded in Medtronic’s distribution records for tracking the tissue to the
consignee or user/tissue transplant facility. This lot number should be recorded in the user/tissue transplant facility’s records
and in the tissue recipient’s medical record, along with the following:

1. Description of tissue

2. Lot number (donor ID)

3. Product code

4. Expiration date

5. Quantity implanted

If for any reason the tissue allograft is opened and not used, it should be disposed of properly or returned to Medtronic.
Document the reason for the tissue not being used.

6. Antibiotics used

7. Description of procedure

8. Date and time of procedure

9. Surgeon name

INSTRUCTIONS FOR USE

Contents of an individual Grafton™ DBM or Grafton Plus™ DBM container are intended for single patient use only. Do not use
the contents of any container for multiple patients. Empty or partially used containers should be disposed of in accordance with
recognized procedures for discarding medical waste materials.

Preparation of the bone graft bed is important for graft incorporation and bone formation, as are other factors such as blood
supply, source of marrow elements, loading, stability, and absence of infection at the graft site. The volume of graft material
used in each procedure is determined by the clinician.

Grafton™ DBM (Gel, Putty) and Grafton Plus™ DBM may be injected into the defect site (see Precautions and
Contraindications).

Before Use, examine product package. Do not use if:

▪ Package materials or contents appear to be missing, tampered with, or damaged.
▪ The package label or identifying bar code is illegible or missing.
▪ The expiration date shown on the package label has passed.
▪ Any of the above conditions exist or are suspected.

Note: once a package seal is broken, the tissue should be either transplanted, if appropriate, or otherwise discarded. Used
containers should be disposed of in accordance with recognized procedures for discarding medical waste material.

Opening Instructions

1. Peel open the outer pouch using proper sterile technique.

2. Pass sterile contents into sterile field.

3. For syringe type containers, remove and discard cap prior to use.

An Allograft Tissue Tracing Record is provided. Affix Peel-Off Labels with tissue identification number to patient records and to
the Allograft Tissue Tracing Record. Fill out information and return as directed. Tissue utilization reports are necessary for
tracing tissue/recipient information in the unlikely event of suspected or actual transmission of disease and allowing for
appropriate actions.

Grafton™ DBM Gel Preparation for Use

Keep the surgical site as dry as possible. Do not irrigate during or after placement of Grafton™ DBM Gel. Fluids such as water,
saline, or blood may alter the consistency and handling characteristics.

If Grafton™ DBM Gel is used in combination with autologous bone tissues, other forms of allografts or other bone grafting
materials, remove any excess fluids (including rehydration solution) from these graft materials before the other grafts come into
contact with Grafton™ DBM Gel.

Grafton™ DBM Putty Preparation for Use

Grafton™ DBM Putty requires no rehydration prior to use. A small amount of fluid such as blood, sterile water, or sterile saline
may be added to adjust consistency or handling. Also, simply kneading the Grafton™ DBM Putty may enhance pliability and
cohesiveness.

Grafton™ DBM Flex Preparation for Use

Grafton DBM Flex™ may be rehydrated prior to use to attain porosity and full flexibility. Add sterile saline or blood until desired
consistency is achieved. Reconstituted product must be used within the time allocated for the surgical procedure.

Grafton™ DBM Crunch™ and Orthoblend Preparation for Use

Grafton™ DBM Crunch™ and Orthoblend require no rehydration prior to use. A small amount of fluid such as bone marrow
aspirate, blood, sterile water, or sterile saline may be added to adjust consistency or handling. Also, simply kneading the
Grafton™ DBM Crunch™ or Orthoblend may enhance pliability and cohesiveness.

Grafton™ DBM Matrix™ Preparation for Use

Grafton™ DBM Matrix™ requires no rehydration prior to use. A small amount of fluid such as blood, sterile water, or sterile
saline may be added to adjust consistency and handling.

Grafton Plus™ DBM Paste Preparation for Use

Grafton Plus™ DBM Paste requires no rehydration prior to use. A small amount of fluid such as blood, sterile water, or sterile
saline may be added to adjust consistency and handling. Also, simply kneading the Grafton Plus™ DBM Paste may enhance
pliability and cohesiveness.

Note: Grafton Plus™ DBM Paste will turn purple or black upon contact with iodine due to the presence of starch in the product.
This color change merely indicates the product has absorbed some iodine and does not present any safety issues beyond those
associated with the iodine itself. If contact of the product with iodine occurs, the surgeon should use discretion regarding use of
the product just as with any other grafting material that would come into contact with iodine.

VISUAL INSPECTION

Visually inspect all sterile-barrier packaging before use. If the sterile barrier is damaged or the integrity has been compromised,
do not use the product. Contact Medtronic for return information.
