FastWire REvascularisation of Extremities, (For LOWer Limbs) - Feasibility Study (FREEFLOW)

December 3, 2025 updated by: Versono Medical Ltd

A First-in-human, Single-arm, Single-center, Feasibility Study to Assess the Efficacy and Safety of the FastWire REvascularisation of Extremities, (For LOWer Limbs) (FREEFLOW)

This study is to assess the safety and efficacy of the FastWire System. It is intended to assess that the FastWire System can facilitate the intra-luminal placement of conventional guidewires or treatment devices beyond peripheral artery chronic total occlusions (CTOs)

Study Overview

Detailed Description

A first-in-human, single-arm, single-center, feasibility study to assess the efficacy and safety of the FastWire System in patients who have a chronic total occlusion in their peripheral vasculature causing an ischemic limb. The enrollment will consist of up to 10 patients meeting the inclusion/exclusion criteria.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: FastWire System - Peripheral
This study is to assess the safety and efficacy of the FastWire System. It is intended to assess that the FastWire System can facilitate the intra-luminal placement of conventional guidewires or treatment devices beyond peripheral artery chronic total occlusions (CTOs). This is a First in Human study
The Investigator can use the FastWire System during the procedure to cross CTO Caps and/or to cross multiple lesions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Freedom from Serious Adverse Events related to the use of FastWire, at 30 days post procedure:
Time Frame: Up to Day 30
  • Cardiovascular deaths.
  • Vessel dissection requiring an intervention to resolve.
  • Unplanned index limb amputation.
  • Symptomatic distal embolization.
Up to Day 30
Technical Success (On Procedure Day)
Time Frame: Day 1
Ability of the FastWire to successfully cross angiographically confirmed chronic total occlusions and provide a platform for delivery of other treatment devices.
Day 1
Clinical success (On Procedure Day)
Time Frame: Day 1
Clinical success is assessed as the angiographically confirmed passage of the FastWire tip through the lesion and the successful delivery and retrieval of FastWire and the delivery of a treatment device to the target site.
Day 1

Secondary Outcome Measures

Outcome Measure
Measure Description

Time Frame: Up to Day 30
Freedom from Serious Adverse Device Effects (SADE).
Up to Day 30
Freedom from Vessel dissection or bleeding (Within 24 Hours)
Time Frame: Within 24 Hours
Freedom from Vessel dissection or bleeding within 24 hours (16-36 hours) of index procedure.
Within 24 Hours
Procedural success (On Procedure Day)
Time Frame: Day 1
Procedural success, defined as achievement of technical success together with post procedure patency (less than 50% residual diameter stenosis of target vessel patent as assessed by angiographic imaging post device retrieval.
Day 1
Procedure related mortality (Up to Day 7 & Day 30)
Time Frame: Up to Day 7 & Day 30
All procedure related mortality at day 7 post procedure, and all-cause mortality at 30 days post procedure.
Up to Day 7 & Day 30
