Critical Limb-Threatening Ischemia

The objective of the study is to evaluate early safety and effectiveness of the percutaneous deep foot venous arterialization performed in clinical practice, in an unselected population of patients with "no-option" CLTI.

The goal of this clinical trial is to learn if using the Chocolate Percutaneous Transluminal Angioplasty (PTA) balloon for vessel preparation improves outcomes before drug-coated balloon (DCB) treatment in patients with femoropopliteal artery narrowing or blockage. It will also learn about the safety of the Chocolate PTA balloon. The main questions it aims to answer are: Does using the Chocolate PTA balloon reduce the need for bailout stenting or vessel complications during DCB treatment? What medical problems do participants have when receiving the Chocolate PTA balloon compared with standard balloon angioplasty? Researchers will compare the Chocolate PTA balloon to standard plain old balloon angioplasty (POBA) to see if it improves vessel preparation before DCB therapy. Participants will: Undergo lesion preparation with either the Chocolate PTA balloon or standard balloon angioplasty, followed by DCB treatment Have clinical and imaging follow-up visits to assess safety and vessel patency Report any complications or adverse events throughout the study

The objective of this prospective, multi-center, clinical investigation is to evaluate the MAGNITUDE BRS System for the planned treatment of narrowed infrapopliteal lesions. Up to 30 subjects will be enrolled at approximately 3 clinical sites in Australia.

The purpose of this clinical trial is to analyze patency after autologous infrainguinal bypass surgery in patients receiving a venous conduit versus a covered venous conduit.
