Support for a heart valve prosthesis
TL;DR: A hart valve prosthesis as mentioned in this paper is formed from a support (1) having a textile covering (3) consisting of flat, closed, preferably thermoplastic material which itself has an approximately hollow cylindrical or hollow conical shape.
Patent
Heart valve prosthesis
TL;DR: A heart valve prosthesis has an annular base carrying two pivoting valving members for use in a heart to control the flow of blood as discussed by the authors, which can be attached to a suturing assembly adapted to be connected to heart tissue.
