Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Serranator™ Alto PTA Serration Balloon Catheter

Experimental: Treatment - Subjects will be treated with the Serranator™ Alto PTA Serration Balloon Catheter device


Treatment: Devices: Serranator™ Alto PTA Serration Balloon Catheter
The Serranator™ is an over-the-wire (OTW) balloon dilatation catheter designed to perform percutaneous transluminal angioplasty (PTA) for peripheral indications.

Outcomes
Primary outcome [1] 0 0
To evaluate the technical feasibility of using the Serranator™ Alto PTA Serration Balloon Catheter during the endovascular treatment of critical SFA or popliteal artery lesions.
Timepoint [1] 0 0
Through Study Completion, approximately 6 months
Secondary outcome [1] 0 0

Timepoint [1] 0 0
Through Study Completion, approximately 6 months

Eligibility
Key inclusion criteria
1. Male or female of >18 years old.

2. Women of child bearing potential must have a negative pregnancy test within 7 days of
index procedure.

3. Subject or subject's legal representative has been informed of the nature of the
study, agrees to participate and comply with all follow-up visits and has signed the
consent form.

4. Resting ABI -< 0.9.

5. Subject is eligible for standard surgical repair in target limb if necessary.

6. Subject has Rutherford Clinical Category 2,3, or 4

7. Estimated life expectancy > 1 year.

Angiographic

1. Lesion(s) located within the SFA and or popliteal arteries.

2. Target lesion(s) has stenosis >70% by visual assessment.

3. Reference vessel diameter is between 4.0mm and 6.0mm, inclusive.

4. One long or multiple serial lesions that are up to 10 cms, (total occlusions up to
6cm) in length that can be covered by a single balloon.

5. De-novo, or non-stented re-stenotic lesions

6. At least one below the knee artery patent to the ankle.

7. Successful treatment of iliac inflow stenosis to the target limb. Stenosis can be
treated during the same procedure using standard angioplasty and or stenting but use
of atherectomy is excluded. The inflow lesion(s) must be treated first, prior to
consideration of treatment of the target lesion. Subject can be enrolled if the inflow
lesion(s) are treated and results in <30% residual stenosis and no evidence of
embolization or significant complications.
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Rutherford Clinical Category 1, 5 or 6.

2. Previously implanted ipsilateral femoral or popliteal stent.

3. Evidence of aneurysm or acute thrombus in the target vessel.

4. Subjects with previous bypass surgery in lower target extremity.

5. Planned major amputation (above the ankle) of either limb.

6. Subject has significant stenosis or occlusion of inflow tract not successfully treated
(>30% residual stenosis and/or significant complication of the procedure).

7. History of any open surgical procedure within the past 30 days.

8. Planned endovascular or vascular surgery procedure within 14 days prior to the ATK
procedure, except to treat the inflow vessels on the day of the procedure, or within
the next 30 days after the ATK procedure on the target limb.

9. Subject has an allergy to contrast medium that cannot be pretreated.

10. Episode of acute limb ischemia within past 30 days.

11. Subject has systemic infection with positive blood cultures/ bacteremia within one
week.

12. Subject has a hypercoagulable disorder

13. Subject in whom antiplatelet, anticoagulant, or thrombolytic therapy is
contraindicated.

14. Myocardial infarction within 30 days prior to enrollment.

15. History of stroke or TIA within 90 days prior to enrollment.

16. Subject has acute or chronic renal disease (e.g., as measured by a serum creatinine of
>2.5 mg/dL or >220 umol/L).

17. Subject is pregnant or breastfeeding.

18. Subject is participating in another research study of a device, medication, which
could, in the opinion of the investigator, affect the results of this study.

19. Subject has other medical, social or psychological problems that in the opinion of the
investigator would preclude them from receiving this treatment and the procedures and
or participating in evaluations pre- and post-treatment.

20. Thrombolysis of the target vessel within 72 hours prior to the index procedure, where
complete resolution of the thrombus was not achieved.

21. Known allergies to both antiplatelet agents, aspirin, or heparin.

22. History of neutropenia, coagulopathy, or thrombocytopenia that was unexplained or is
considered to be at risk for reoccurrence.

23. Platelet count less than 80,000/µL,

24. Subject requires general anesthesia for the procedure.

25. Subject requires dialysis.

Angiographic

1. Chronic Total Occlusions (CTO) > 6cm in length

2. Acute Total Occlusions; evidence of acute thrombus formation by angiography

3. Severe calcification of target lesion described as circumferential calcium and >50% of
lesion length.

4. Sub-intimal access required

5. Inability to cross the lesion with a guidewire

6. Atherectomy in the target lesion, target artery or for inflow treatment
