Brief Summary

Below-the-Knee Interventions for Limb Salvage: Use of Multifunctional Angioplasty Balloon Catheters ("BTK Multicath Registry")

A non-randomized clinical registry

This study is designed to obtain preliminary data on clinically relevant procedural variables during percutaneous below-knee artery revascularization procedures among consecutive patients treated with either the Finesse BTK Multicath® ("Finesse") or the standard of care using conventional angioplasty balloon catheters.

This registry will enroll participants with a history of chronic limb threatening ischemia and below-knee arterial insufficiency who will be assigned to revascularization with or without use of the Finesse BTK Multicath. The registry is an acute study examining procedural data only. The primary endpoints of interest are the volume of contrast used for the intervention, overall procedure time, radiation dose, number of catheter exchanges during revascularization, and medical device supply costs. For the first phase 12 consecutive patients will be treated with the standard of care. For the second phase 12 consecutive patients will be treated with Finesse.

24 participants total
