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

Condition Intervention Phase
Total Atherosclerotic Occlusion of Femoral Artery
Device: CTO crossing in femoropopliteal arteries CONNECT II
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Non-randomized Study of the Avinger Ocelot System Used to Cross Chronic Total Occlusions in the Superficial Femoral and Popliteal Arteries

Further study details as provided by Avinger, Inc.:

Primary Outcome Measures:
  • Primary Safety Endpoint [ Time Frame: Day 30 ]
    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.

  • Primary Efficacy Endpoint [ Time Frame: Day 0 ]
    Successful femoropopliteal CTO crossing using the Ocelot System as identified by guidewire placement in the distal true lumen confirmed by angiography.

Secondary Outcome Measures:
  • Procedural Success [ Time Frame: Day 0 ]
    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.

  • Technical Success [ Time Frame: Day 0 ]
    Successful delivery, crossing and retrieval of the investigational device without the use of an assist device.

  • Device Performance [ Time Frame: Day 0 ]
    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.

  • Procedural Times [ Time Frame: Day 0 ]
    Evaluation of procedural times.

  • Fluoroscopic Times [ Time Frame: Day 0 ]
    Evaluation of fluoroscopic times.

  • Crossing Times [ Time Frame: Day 0 ]
    Evaluation of crossing times.

  • Use of Assist Devices [ Time Frame: Day 0 ]
    Evaluation of the use of assist devices.

  • Contrast/Flush Volumes [ Time Frame: Day 0 ]
    Evaluation of the contrast/flush volumes.

Detailed 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.
