Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot study will investigate the safety, effectiveness and feasibility of the LimFlow Stent Graft System for creating an AV fistula in the Below The Knee (BTK) vascular system using an endovascular, minimally invasive approach for the treatment of Critical Limb Ischemia (CLI) in subjects ineligible for conventional endovascular or surgical limb salvage procedures.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The PROMISE I Trial was a prospective, multi-center, single-arm, investigational feasibility study assessing the LimFlow System for the treatment of chronic- limb-threatening ischemia by creating an arterio-venous fistula in the below-the-knee vasculature. The study was run under an investigational device exemption (IDE G160156, NCT03124875).

Thirty-two subjects were enrolled under protocol revisions A, B, C, and D at seven sites in the United States between 5-July-2017 and 8-April-2019.
