Experimental: Tack Implant
Implantation of a Tack using the Intact Vascular Tack Endovascular System for the repair of post angioplasty dissections below the knee.
Device: Tack Endovascular System
Repair of post-PTA dissections using the Intact Vascular Tack Endovascular System.
- Efficacy - Freedom from MALE at 6 months [ Time Frame: 6 months ]Freedom from major adverse limb events (MALE) at 6 months defined as above-ankle target limb amputation or major re-intervention to the target lesion(s) (i.e. new bypass graft, jump/interposition graft revision, or thrombectomy / thrombolysis)
- Efficacy - Freedom from POD at 30 days [ Time Frame: 30 days ]Freedom from perioperative death (POD) at 30 days
- Safety - Freedom from MALE at 30 days [ Time Frame: 30 days ]Freedom from major adverse limb events (MALE) at 30 days defined as above-ankle target limb amputation or major re-intervention to the target lesion(s) (i.e. new bypass graft, jump/interposition graft revision, or thrombectomy / thrombolysis)
- Safety - Freedom from POD at 30 days [ Time Frame: 30 days ]Freedom from perioperative death (POD) at 30 days
- Patency [ Time Frame: 6 months ]Target lesion(s) tacked segment(s) patency at 6 months defined as the presence of blood flow using duplex ultrasound. If angiography is available within the 6 month follow-up visit window, it should be used in place of the duplex ultrasound. Evidence of no blood flow within the Tacked segment indicates restenosis/loss of patency.
- Target Limb Salvage [ Time Frame: 6 months ]Target Limb Salvage defined as freedom from any above-ankle target limb amputation at 6 months.
