1. Device Description

The Complete SE vascular stent system is used to deliver a self-expanding stent to the superficial femoral/proximal popliteal arteries via a sheathed delivery system. The system is comprised of 2 main components: the implantable vascular stent (Figure 1) and the disposable delivery system (Figure 2). The stent is compressed and preloaded into the delivery system (Figure 3) and advanced to the target lesion, where the protective sheath is retracted. Upon deployment, the stent self-expands to provide a vessel support frame and to impart an outward radial force on the arterial lumen to establish patency.

1.1. Stent

Figure 1. Complete SE Vascular Stent with Tantalum Markers
Note: This and all other product graphics appearing in this manual are not drawn to scale.
The Complete SE vascular stent is constructed of a nickel-titanium alloy (nitinol) and has 4 tantalum radiopaque markers on each end to aid in visualization and facilitate placement. The series of segments, each connected to the next, allow for flexibility and vessel conformability. It is available in diameters of 5 mm to 8 mm and lengths of 20 mm to 150 mm. See Table 2 in Recommended Device Sizing (Section 10.2).

4. Front grip
The Complete SE vascular stent delivery system consists of a single-use, disposable catheter with an integrated handle to provide controlled deployment. It has a working length of either 80 cm or 130 cm and is compatible with a 6 Fr sheath and 0.035 in (0.89 mm) guidewire.
The over-the-wire retractable sheath delivery system is composed of a tip and flexible outer member sheath (braided) body attached to the strain relief handle, which includes the front grip and the deployment rotation/slider mechanism with a removable safety lock. The outer member sheath is retracted by engaging the deployment slider/rotation mechanism. Radiopaque marker bands are located on both the distal and proximal sides of the preloaded stent to aid placement (Figure 3).

Instructions for Use English 3
The Complete SE vascular stent system does not contain natural rubber latex. However, during the manufacturing/assembly process, it may have incidental contact with latex-containing products.

2. Indications for Use

The Complete SE vascular stent system is indicated to improve luminal diameter in symptomatic patients with de novo and/or restenotic lesions or occlusions of the superficial femoral artery (SFA) or proximal popliteal artery (PPA) with reference diameters ranging from 4 mm to 7 mm and lesion lengths up to 140 mm.

3. Contraindications

The Complete SE vascular stent system is contraindicated in:
patients who are judged to have a lesion that prevents complete inflation of an angioplasty balloon or proper placement of the stent or stent delivery system
patients who cannot receive antiplatelet or anticoagulation therapy
Also consider patient selection information in Warnings and Precautions (Section 4).

4. Warnings and Precautions Caution: Read all instructions carefully. Failure to properly follow the instructions, warnings, and precautions may result in serious consequences or injury to

the patient.

4.1. General

The Complete SE vascular stent system should only be used by physicians and medical personnel trained in vascular interventional techniques (including advanced iliac or SFA angioplasty or stenting techniques) and trained on the use of this device. Specific training expectations are described in Physician Training Requirements (Section 10.1).
Caution: Federal (USA) law restricts this device for sale by or on the order of a physician.

4.2. Warnings

Do not use if the temperature indicator found on the inner pouch is changed from a gray square to a black square as this indicates the unconstrained stent diameter and stent release may be compromised.
Administer appropriate antiplatelet/anticoagulation therapy pre- and post- procedure. Use of this device in patients who are unable to tolerate appropriate antiplatelet therapy is not recommended.
Do not use the Complete SE vascular stent system in patients unable to undergo, or who will not be compliant with, the necessary preoperative and postoperative imaging and implantation procedures.
Careful stent sizing is important. In vitro modeling has predicted the Complete SE vascular stent foreshortens between 0% (5 mm stents) and 8% (8 mm stents). See Table 2 for available diameters and lengths (Section 10.2).
The use of overlapping stents with the Complete SE vascular stent system has not been formally evaluated in a clinical study; overlap stents have been evaluated on the bench/Finite Element Analysis (FEA) and results are on file at Medtronic.
To achieve optimal sizing and apposition to the vessel wall, using an interference fit, stents should be at least 0.5 mm greater in diameter than the target vessel. Consideration should also be given to the length of the lesion to be treated when selecting the stent length. See Recommended Device Sizing (Section 10.2).
To avoid kinking of the delivery system, stabilize the hub of the guiding catheter or introducer sheath, hold the catheter shaft just proximal, and use short strokes to advance the delivery catheter over the immobilized guidewire.
Do not deploy the stent if it is not optimal or appropriate for the vessel. The stent cannot be repositioned once the stent has begun to appose the vessel wall.
Use caution when placing a stent near a bifurcation, aneurysm, or bypass graft.
Prior to stent deployment, use fluoroscopy to verify the stent has not been damaged or dislodged during positioning.
If unable to initiate stent release, remove the entire system from the patient and advance a new stent delivery system.
Once deployment is initiated, the stent cannot be recovered by the sheath. In the event of partial delivery of the stent, remove the entire delivery system from the patient. This may result in damage to the vessel wall and require surgical intervention.
Prior to completion of the procedure, use fluoroscopy to ensure the stent is deployed in the proper position. If the target lesion is not completely covered by the stent, use additional Complete SE vascular stent(s) as necessary to adequately treat the lesion.
Should unusual resistance be felt at any time during placement or removal of the stent or delivery system, cautiously remove the entire system. Applying excessive force to the Complete SE vascular self-expanding stent system can potentially result in loss, damage, or partial deployment of the stent and the delivery system components.

4.3. Precautions

The Complete SE vascular stent system should only be used by physicians and medical personnel trained in vascular interventional techniques (including SFA angioplasty or stenting techniques) and trained on the use of this device. Specific training expectations are described in Physician Training Requirements (Section 10.1).
The long-term safety and effectiveness of the Complete SE vascular stent system has not been established beyond one year.
The safety and effectiveness of this system has not been evaluated in patients who:
are less than 18 years old
are pregnant or lactating
have any condition that precludes safe access with PTA devices
have in-stent restenosis of the target lesion
have a known hypersensitivity to any component of the stent system (eg, nickel)
cannot tolerate aspirin and heparin
cannot tolerate contrast media and cannot be pretreated
have a history of bleeding diathesis or coagulopathy or will refuse blood transfusion
have creatinine >2.5 mg/dl
Inappropriate patient selection may result in poor device performance or device performance otherwise not in accordance with the specifications.
Thrombogenicity evaluations were conducted using a heparinized model. If your patient cannot be adequately anticoagulated, it is unknown whether thrombus formation may occur with this product.
Caution must be taken when crossing the stented area with ancillary equipment to avoid dislodging the stent.

6. Summary of Clinical Study

The clinical evidence supporting the safety and effectiveness of the Complete SE vascular stent system for the treatment of de novo or restenotic lesions or occlusions (140 mm) in the SFA or PPA in subjects with symptomatic peripheral artery disease (PAD) is from the Complete SE SFA/PPA Study.

6.1. The Complete SE SFA IDE Study

The Complete SE SFA Study is a nonrandomized, prospective, multicenter, single-arm study enrolling up to 196 subjects with symptomatic ischemic PAD (Rutherford class 2 through 4) with a lesion 50%, a target vessel reference diameter 4 mm and 7 mm, total lesion length 40 mm and 140 mm (visual estimates), and adequate distal runoff to the foot. Lesions were located above the knee and amenable to percutaneous treatment with angioplasty and vascular stent implantation. For treatment of multiple lesions, the combined lesion length must be 140 mm. The lesions must be in the same limb, and the treatment must not require more than 150 mm in combined stent length.
6.1.1. Patient Population
196 subjects were enrolled at 28 sites (United States, Belgium, and Germany) with a mean age of 69 years (range: 40 to 93), including 124 males (63%). Subject demographics, medical history, and risk factors are summarized (Figure 4).

6.1.2. Methods
Direct stent placement was at the discretion of the physician. The target lesion was to be predilated (with standard PTA balloons) if necessary to cross the lesion. Prior to the procedure, the subject was given an oral dose of aspirin (325 mg). Prior to stent placement, heparin was administered to achieve ACT. Target lesions were treated with 1 or 2 stents.

a
Percentage based on number of evaluable subjects for MAE. Subjects are considered unevaluable for MAE at 30 days if a) withdrawn before 25 days without having MAE events
or b) lost to follow-up before 25 days without having MAE events and had no contact thereafter
b
Percentage based on number of evaluable subjects for MAE. Subjects will be considered unevaluable for MAE at 6 months if a) the subject withdrew before 150 days without having MAE events or b) the subject was lost to follow-up before 150 days without having MAE events and had no contact thereafter or c) any device and/or procedure-unrelated death occurred after 30 days and before 150 days without having MAE events
c
Device success defined as angiographic evidence of <30% final residual stenosis of the target lesion using only the assigned
d
Lesion success defined as angiographic evidence of <30% final residual stenosis of the target lesion using either the Complete SE SFA Stent System or other standard percutaneous devices. Percentage based on number of lesions with available data
e
Procedure success defined as angiographic evidence of <30% final residual stenosis of the target lesion after stent implantation and no occurrence of a procedure-related MAE prior to hospital discharge. Percentage based on number of subjects with available data (for subjects with more than one lesion stented the worse case is counted)
f
Defined as vessel patency resulting from a procedure performed in the treated segment to restore blood flow after restenosis. For patients with multiple TLR events, only the earliest TLR will be considered for Assisted Primary Patency. Percentage based on number of subjects with available duplex data
g
Defined as vessel patency resulting from any procedure that restores patency. Percentage based on number of subjects with available duplex data. For patients with multiple TLR events, any TLR will be considered for Secondary Patency.
h
Percentage based on number of subjects with available data at related time point
i
Percent free from strut fractures. Percentage based on number of stents implanted with flat plate x-ray follow-up
j
Clinically-driven TLR is defined as those revascularizations in which the subject has ischemic symptoms consistent with changes within the target lesion as demonstrated by: a change (decrease from post-procedure) in the Rutherford scale by at least one category, or a change (decrease from post-procedure) in ABI/TBI ≥0.15 N = Intent-To-Treat Population Note: Site, CEC, Duplex and Angiographic Core Laboratory Reported Table
6.1.7. Secondary Endpoints and Results
As presented (Figure 12), the 30-day MAE rate was 0.5% (1/196). The device, lesion and procedure success rates were between 89-90%. The secondary patency rate at 12 months was 78.9% (138/175). The clinically-driven target revascularization (TLR) rate at 12 months was 8.4% (16/191). Clinically-driven TLR is defined as those revascularizations in which the subject has ischemic symptoms consistent with changes within the target lesion as demonstrated by a changed (decrease from post-procedure) in the Rutherford scale by at least one category, or a change (decrease from post-procedure) in ABI/TBI ≥0.15.
There were 3 measures of Quality of Life observed at 12 months: Improvement in Rutherford Class by 1 category at 12 months was 90.9%; the increase in ankle-brachial index/toebrachial index (ABI/TBI) of 0.15 at 12 months was 64.5%; and the decline in Rutherford Class 1 at 30 days was 89.7%.
Analyses of all flat-plate X-rays by the Vascore core laboratory indicated that there were 8 (4.2%) stent fractures observed at 12 months, and of those fractures, 7 were grade 1, 1 was grade 2, and 0 were grade 3, grade 4, or grade 5. Medtronic conducted an additional stent fracture analysis and determined that there were zero fractures. For additional information, see Additional Stent Fracture Analysis (Section 6.1.7.1).
