Stent With Mechanical Or Biological Heart Valve For Minimally Invasive Valve Replacement Procedure And Stent Application Device

摘要

A cardiac stent assembly featuring support flaps for a heart valve replacement procedure, while being able to place a mechanical or biological valve in an adapter fixed on the inner part of a stent body of the stent assembly. The stent assembly can be placed within heart valves sustained on an annular or ovoid mechanical support ring. For the positioning procedure of the stent assembly in the valve, an application device can be used wherein the stent body is inside the application device so that is possible to assemble and keep the entire stent assembly ready for use.

主权项

1. A stent assembly comprising:
a stent body of tubular shape and grated structure; an upper flap; and a lower flap; and an adapter; wherein the lower flap is in proximity to and parallel to the upper flap, located at an intermediate part of the stent body; wherein both the upper and lower flaps and the stent body are made of wired material and at least partially coated with an inert material, which allows physiological movement of the mitral annulus and fitting of the adapter; and wherein the adapter is used to support a heart valve within the stent between both the upper and lower flaps.
