Mechanical transcatheter heart valve prosthesis

摘要

The mechanical transcatheter heart valve prosthesis has a support structure that is expanded from a size designed for minimally invasive insertion to a functional another size. A flexible heart valve is made of a composite material comprises woven fabric (10) that is embedded in an elastic matrix and locally reinforced by fibers. The heart valve has multiple leaflets. The heart valve is reinforced in a peripheral section by the fibers, where the peripheral section is provided adjacent to the support structure. The fibers are made of high-density polyethylene.
