AI Technical Summary

⚠Technical Problem

Current treatments for thromboembolic disorders, such as stroke and pulmonary embolism, often require invasive surgical procedures and have high recurrence rates, difficulty in removing large clot volumes, and involve multiple devices, necessitating a more efficient and effective method for clot disruption within blood vessels.

⚗Method used

A radially expandable/contractable cutting device with a coring element, featuring expandable/contractable balloons and edge modifications, designed to mechanically disrupt and cut obstructions within blood vessels, facilitating clot removal and vessel preparation for angioplasty or stenting.

🎯Benefits of technology

The cutting device effectively reduces occlusion recurrence and improves treatment efficiency by mechanically disrupting clots, enhancing blood flow restoration and reducing the need for multiple treatment modalities.

Abstract

Disclosed herein is a cutting device including a coring element including one or more edge modifications, the edge modifications configured to at least partially cut an obstruction within a vessel. The coring element is configured to radially expand from a first position to a second position, wherein the second position enables the coring element to cut the obstruction within the vessel. More specifically, a balloon positioned within an interior portion of the coring element is inflated to expand the coring element from the first position to the second position.
