Summary

A surgical device comprising design features to allow flexibility and differential size accommodations for peripheral vascular plaque removal.

 

Technology Overview

In the United States alone, 8-12 million people have peripheral arterial disease. These numbers are increasing due to persistent risk factors such as smoking, diabetes, and age. Remote endarterectomy is used in peripheral vascular surgery to remove plaque from an occluded femoral artery. Products currently used by surgeons have limited flexibility with a fixed diameter metal ring that cannot accommodate changes in the size of the artery and irregular, calcified plaque formation. Problems arise with vessel perforation, plaque breakage and incomplete plaque removal. OHSU researchers have developed an improved product incorporating human factors features and flexibility of the ring to more easily remove plaque and encompass a wider range of applications such as stent removal.  A proof of concept device has been developed and potential advantages of the OHSU device include:

 

•       Safely remove arterial plaque of varying sizes and configurations;

•       Versatility of device allows for additional uses;

•       Similarity to existing methodology means easier adoption by surgeons.
