Preferential Covered Stent for Embolic Prevention & Preserving Side Branch Perfusion

Technology Overview

This is a membrane-coated stent covered with multiple flaps. The flaps are constructed in a way that they open up and allow perfusion into the areas where side branches are present, when positive pressure blood flows inside the coated stent and in non-branched area, they will be pushed against the vessel wall. It demonstrated significantly higher emboli prevention capability than the corresponding bare metal stent, while preserving more than 83% of the original flow of the external carotid artery.

Technology Features & Specifications

This design enables preferential blood flow to the side branch in the presence of a covered stent in the blood vessel.  A stent with outer surface coated with a membrane. Multiple flaps have been created on the membrane. The membrane and the closed flap act as a barrier between the inner wall of the blood vessel and the blood flow inside the lumen.

Potential Applications

It has potential applications in Cardiology due to the following: Constrains the friable atherosclerotic plaque over the inner wall of carotid artery and preserve perfusion to the external carotid artery. Uniform flow in the external carotid artery through the stents without evidence of undesirable flow recirculation and reversed flow that might predispose the vessel wall to intimal thickening and atherosclerotic plaque formation.
