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

2. Women of child bearing potential must have a negative urine 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. Subject is eligible for standard surgical repair in target limb if necessary.

5. Subject has Rutherford Clinical Category 3, 4 or 5. Enrollment of Rutherford 3 will be
limited to no more than 40% of total subjects.

6. Estimated life expectancy > 1 year.

Angiographic

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

2. De-novo, or non-stented re-stenotic lesions;

3. Reference vessel diameter is between 2.5 mm and 3.5 mm, inclusive;

4. Target lesions involve infra-popliteal tibial arteries above the tibio-talar joint;

5. Up to two target lesion(s) may be treated. These target lesions may be located in a
single or two infrapopliteal arteries;

6. A target lesion may consist of one long or multiple serial lesions that are up to and
including 12 cm in length that can be covered by a single balloon (longest balloon
length for this study will be 12 cm);

7. If more than one critical lesion is identified in two different vessels but only one
lesion matches the inclusion criteria, that lesion should be treated as the target
lesion and the other non-qualifying lesion in the other vessel may be treated with
commercial devices in any manner the investigator decides except by atherectomy;

8. If two critical lesions are identified in two vessels and both qualify for the study,
the investigator may treat both lesions with investigational balloons or may choose to
identify one lesion as the target lesion and treat the second lesion with commercial
devices except atherectomy;

9. If two critical lesions are in one vessel and both lesions qualify for the study, both
lesions should be treated with investigational balloons. Lesions that are within 3 cm
of each other will be treated as a single lesion;

10. Target vessel(s) reconstituted at or above the ankle with inline flow to at least one
patent inframalleolar outflow vessel in each target vessel. If the peroneal artery is
the treated artery, it should supply collaterals at the ankle that reconstitute an
inframalleolar outflow vessel;

11. Successful treatment of inflow stenosis (DS>50%), from the iliac to the target lesion.
Stenosis can be treated during the same procedure using standard angioplasty, DCB,
DES, 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
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Rutherford Clinical Category 1, 2, or 6

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

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

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

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

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

7. Planned endovascular procedure within 14 days prior to the BTK procedure, except to
treat the inflow vessels on the day of the procedure, or a planned endovascular or
open surgical procedure within the next 30 days after the BTK procedure on either
limb.

8. Planned intervention of occluded or stenotic pedal arteries at the time of the index
procedure.

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.

26. Subject has heel gangrene and anything worse than WIfI 2.

Angiographic

1. De-novo, or non-stented re-stenotic lesions or Chronic Total Occlusions (CTO) > 12 cm
in length.

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

3. In-stent restenotic lesions.

4. Inability to cross the lesion with a guidewire.

5. Atherectomy for inflow treatment or planned use in below the knee vessel(s)

6. Intended use of adjunctive primary treatment modalities of target lesion(s)
(atherectomy, laser, cutting balloons, DCBs, stents).

7. If two critical lesions are in one vessel but only one lesion qualifies, and the other
does not, the subject should not be included in the study
