AngioSafe Peripheral CTO Crossing System Study (RESTOR-1 Study)
- Conditions
- Peripheral Artery OcclusionPeripheral Arterial Disease
- Interventions
- Device: AngioSafe Peripheral CTO Crossing System
- Registration Number
- NCT04663867
- Lead Sponsor
- AngioSafe, Inc.
- Brief Summary
The study is designed to evaluate the safety and efficacy of the AngioSafe Peripheral CTO Crossing System.
- Detailed Description
The purpose of the study is to demonstrate the safety and effectiveness of the AngioSafe Peripheral CTO Crossing System. The system facilitates the crossing of chronic total occlusions (CTOs) in the peripheral arteries of lower limbs. A minimum of 70 subjects will be treated across selected study enters within the U.S. and followed for 30 days.

Group Intervention Description AngioSafe Peripheral CTO Crossing System Procedure AngioSafe Peripheral CTO Crossing System -
- Primary Outcome Measures
Name Time Method Clinical Success of AngioSafe Peripheral CTO Crossing System 24 Hours Defined as the ability of catheter to facilitate placement of a guidewire into the distal lumen in the absence of device-related major adverse events through discharge or 24-hours post-procedure, whichever is sooner.
- Secondary Outcome Measures
Name Time Method Technical Success of AngioSafe Peripheral CTO Crossing System Procedure Defined as the ability of catheter to facilitate placement of a guidewire into the distal lumen.
Procedural Success of AngioSafe Peripheral CTO Crossing System 30 Days Defined as the ability of catheter to facilitate placement of a guidewire into the distal lumen without a procedural complication within 30 days after the procedure. Procedural complication is defined as the need for open or repeat endovascular surgical repair in the treated limb, or a major bleeding event.
Evaluation of intraluminal CTO crossing facilitated by the Peripheral CTO Crossing System, as assessed by an Intravascular Ultrasound (IVUS). Procedure Post-procedure IVUS evaluation of technical success cases to determine if crossing was performed intraluminally.
The primary endpoint in the subgroup of the degree of calcification (none/focal/mild/moderate, severe). Procedure Defined as the ability of catheter to facilitate placement of a guidewire into the distal lumen in the absence of device-related major adverse events through discharge or 24-hours post-procedure, whichever is sooner, analyzed by degree of calcification.
