DEVICE DESCRIPTION
OptiSphere embolization spheres consist of
biodegradable gelatin spheres pre-lled and
provided in a sterile, 20mL syringe. OptiSphere
is provided as either 1mL or 2mL of spheres
suspended in saline, at a total suspension volume
of approximately 6mL.
In an animal model, sphere degradation was
observed starting at 4 weeks; by 12 weeks, most
spheres were fully resorbed. The majority of treated
vessels showed no signs of recanalization at 12
weeks for both OptiSphere embolization spheres
and the comparative, commercially-available, non-
degradable, control product, based on uoroscopic
and histologic examinations in an animal model
OptiSphere embolization spheres are not
radiopaque. Monitor the procedure under
uoroscopy by adding the appropriate amount of
contrast to aid in the suspension and delivery of the
spheres.

OptiSphere embolization spheres are manufactured
using an emulsion system and crosslinked with
glutaraldehyde.
The OptiSphere embolization spheres have been
sterilized using Gamma irradiation.
SPECIFICATIONS
OptiSphere embolization spheres are available
in four sizes, differentiated by a specic label and
syringe plunger color, as indicated in the chart
below:

300-500μm Blue OSL135 OSL235 0.020”
500-700μm Red OSL157 OSL257 0.023”
600-800μm Silver OSL168 OSL268 0.027”
700-1000μm Green OSL171 OSL271 0.038”
INDICATIONS
OptiSphere embolization spheres are intended for
use in embolization of hypervascular tumors.
CONTRAINDICATIONS
• Patients with a known hypersensitivity to
porcine products
• Coronary and intracerebral vascular use
• In the pulmonary vasculature
• Patients intolerant to vascular occlusion
procedures
• Vascular anatomy or blood ow precluding
correct catheter placement or embolic injection

Catheter
• Presence or suspicion of vasospasm
• Presence or likely onset of hemorrhage
• Presence of severe atheromatous disease
• Feeding arteries too small to accept the
selected device
• Presence of collateral vessel pathways
potentially endangering normal territories
during embolization
• High ow arteriovenous shunts or stula with
luminal diameter greater than the selected
size of the device
• Vascular resistance peripheral to the feeding
arteries precluding passage of the device into
the lesion
WARNINGS
The OptiSphere embolization spheres are provided
sterile for single use only. Reuse of a singleuse device creates a potential risk of patient
or user infections and may compromise device
functionality, which may lead to illness or serious
patient injury.
OptiSphere embolization spheres should not be
used in the presence of infection. Gelatin-based
materials may serve as a nidus for infection and
abscess formation and have been reported to
potentiate bacterial growth.
PRECAUTIONS
Do not use the OptiSphere embolization spheres if
the packaging is damaged. A damaged package
could indicate a breach of sterility or device
damage.
Inspect the device for damage prior to use. Use of
a damaged device could result in injury.
Prior to delivering OptiSphere embolization
spheres, conrm that the selected delivery catheter
(not included) meets the minimum required inner
diameter for the selected sphere size. Use of a
delivery catheter that does not meet the minimum
inner diameter requirements may prevent delivery
or result in injury.
Prior to delivering OptiSphere embolization
spheres, conrm that the catheter is in the desired
location. Failure to conrm appropriate catheter
placement may result in non-target embolization.
OptiSphere embolization spheres are available in a
range of sizes and care should be taken to choose
the appropriate size for the site intended to be
treated. Improper size selection may result in injury.
I.D.
If the delivery catheter becomes obstructed or
signicant resistance is encountered during
injection, do not attempt to ush the catheter with
excessive pressure as non-target embolization may
occur.
ADVERSE EFFECTS
Potential adverse effects that may be associated
with the OptiSphere embolization spheres include,
but are not limited to, the following:
• Abscess
• Allergic reaction/anaphylaxis
• Capillary bed occlusion and tissue damage/
necrosis
• Fluid encapsulation
• Foreign body reactions
• Hematoma
• Hemorrhage
• Infection
• Inammation
• Ischemia at undesirable location
• Non-target embolization
• Pain
• Post-embolization syndrome

• Pulmonary embolism
• Seroma
• Transient hypertension
• Vasospasm
• Vessel or lesion rupture
CLINICAL PROCEDURE
The OptiSphere embolization spheres should be
used by physicians trained on the procedures for
which the device is intended. The techniques
and procedures described do not represent
ALL medically acceptable protocols, nor are
they intended as a substitute for the physician's
experience and judgment in treating any specic
patient. All available data, including the patient’s
signs and symptoms and other diagnostic test
results, should be considered before determining a
specic treatment plan.
Package contains:
• One (1) 20mL pre-lled syringe, packaged in a
peel-away tray. Each syringe contains one of
the following:
• Approximately 1 mL of OptiSphere
embolization spheres suspended in 5 mL
of sterile saline for injection
• Approximately 2 mL of OptiSphere
embolization spheres suspended in 4 mL
of sterile saline for injection
Other items required but not provided:
• Delivery catheter system with a minimum inner
diameter as specied in the above table.
• 1mL injection syringe
• Luer-lock 3-way stopcock
• Contrast media
PREPARATIONS FOR USE
Prior to use, carefully inspect the OptiSphere
embolization spheres packaging and components
for damage.
Utilizing sterile technique, remove the OptiSphere
embolization spheres from its packaging and
transfer to the sterile eld.
DEPLOYMENT PROCEDURE
Deploy the OptiSphere embolization spheres
according to the following steps:
1. Introduce the delivery catheter into the target
vessel according to standard techniques.
Position the catheter tip as close as possible
to the treatment site to avoid inadvertent
occlusion of normal vessels.
2. Attach a luer-lock 3-way stopcock to back end
or hub of the delivery catheter. Attach a 1mL
injection syringe to a female end of 3-way
stopcock. Flush system and ensure that air is
purged.
Note: Agitate syringe prior to use if
aggregates of spheres are clearly visible.
3. Remove any surplus air from the OptiSphere
syringe. Match the total volume in the pre-
lled syringe with an approximately equivalent
volume of undiluted contrast, which will result
in a 50% contrast 50% saline/sphere solution.
4. Gently invert the syringe several times until
the beads are evenly suspended in the
solution.
5. Attach the 20mL OptiSphere syringe to the
remaining port of the luer-lock 3-way stopcock.
6. Ensure the stopcock port connected to the
delivery catheter is closed and then draw the
solution into the 1mL injection syringe slowly
to minimize the potential of air introduction.
Note: Ensure all air is purged from system
prior to injection.
7. Inject the solution in the 1mL injection syringe
under uoroscopy using a slow, pulsatile
injection method while observing the contrast
ow rate.
8. If there is no effect on the contrast ow
rate, repeat delivery process with additional
injections of the solution.
9. Upon completion of the embolization
procedure, remove the delivery catheter while
maintaining gentle suction so that OptiSphere
embolization spheres remaining within the
catheter lumen are not dislodged.
10. Dispose of the product following standard
hospital procedures
