HEART VALVE PROSTHESIS FOR PERCUTANEOUS REPLACEMENT OF A TRICUSPID VALVE, SET AND SYSTEM COMPRISING A HEART VALVE PROSTHESIS OF SAID TYPE

摘要

The invention relates to a heart valve prosthesis (10) for percutaneous replacement of a tricuspid valve, comprising a stent-type support structure (11) and a biological heart valve; the stent-type support structure (11) can autonomously expand from a radially compressed state into a radially expanded state; in the radially expanded state, the stent-type support structure has a constriction (15) which separates the support structure (11) into a vena cava portion (13) and an atrium portion (14), in which the heart valve is arranged. The invention further relates to a system comprising a heart valve prosthesis of said type as well as a set of two heart valve prostheses, comprising a first heart valve prosthesis to be introduced into the superior vena cava, and a second heart valve prosthesis to be introduced into the inferior vena cava.
