Clinical Trial Summary

Evaluation of the safety and effectiveness of the Ocelot System to provide OCT-assisted orientation while simultaneously crossing totally occluded femoropopliteal arteries.


Description:

The purpose of this clinical study is to evaluate the safety and effectiveness of the Ocelot System to provide OCT-assisted orientation while simultaneously crossing chronic total occlusions (CTOs) in femoropopliteal arteries. The Ocelot Catheter is a minimally invasive percutaneous device that is designed to traverse arterial occlusions through the use of spiral wedges contained in the distal tip of the device. The device is also equipped with an OCT (optical coherence tomography) imaging fiber that provides directional orientation and an intravascular view of the vessel wall and target lesion. The Ocelot Catheter is used in conjunction with standard endovascular devices and as an adjunct to fluoroscopic guidance.

Outcome

Type Measure Description Time frame Safety issue
Primary Primary Safety Endpoint No evidence of in-hospital MAEs, 30 day MAEs, clinically significant perforations, clinically significant embolizations or Grade C or greater dissections after Ocelot System CTO crossing confirmed by angiography. Day 30
Primary Primary Efficacy Endpoint Successful femoropopliteal CTO crossing using the Ocelot System as identified by guidewire placement in the distal true lumen confirmed by angiography. Day 0
Secondary Procedural Success Successful delivery, crossing and retrieval of the investigational device in the absence of in-hospital MAEs, clinically significant perforations, clinically significant embolizations or Grade C or greater dissections. Day 0
Secondary Technical Success Successful delivery, crossing and retrieval of the investigational device without the use of an assist device. Day 0
Secondary Device Performance Device performance as assessed by Investigator's input by evaluating both performance of the device and quality of the OCT image as it relates to the ability to identify layered and non-layered structures and the ability of the directional marker bands to aid in orientation of the catheter while advancing through the CTO. Day 0
Secondary Procedural Time Total time of the procedure from the insertion of the catheter to its removal following treatment of the CTO Day 0
Secondary Fluoroscopic Time Total time fluoroscopy was used during the procedure. Day 0
Secondary CTO Crossing Time Time required to cross the CTO during the procedure. Day 0
Secondary Use of Assist Devices Comparison of the crossing times for the Ocelot System alone versus the Ocelot System with assist devices. Day 0
Secondary Contrast/Flush Volumes Contrast and flush volumes are presented Day 0
