Heart valve prosthesis for percutaneous replacement of a tricuspid valve, and system comprising a heart valve prosthesis of said type
First Claim
1. A heart valve prosthesis, for the percutaneous supplementation or replacement of an organic tricuspid valve, the heart valve prosthesis having an overall tubular form and comprising:
- a stent-type support structure and a biological heart valve,the stent-type support structure configured to autonomously expand from a radially compressed state into a radially expanded state; and
a fluid-tight tubular covering extending over a circumference of at least longitudinally central portions of the stent-type support structure, whereinthe biological heart valve is disposed in a lateral opening formed in a common tubular wall plane of both the stent-type support structure and the fluid-tight tubular covering, the lateral opening extending through a tubular wall of the stent-type support structure and the fluid-tight tubular covering to form an exit from an inner tubular lumen of the heart valve prosthesis,the biological heart valve is disposed within the lateral opening and occluding the lateral opening;
the heart valve prosthesis is configured to form an overall tubular connection extending between the superior vena cava and the inferior vena cava of an organic heart, andwhen the stent-type support structure is in the radially expanded state, a circumference of the stent-type support structure at one or more of an end of the heart valve prosthesis corresponding to the superior vena cava and an end of the heart valve prosthesis corresponding to the inferior vena cava is at least as large as a transverse circumference of the stent-type support structure and the fluid-tight tubular covering both immediately above the lateral opening and Immediately below the lateral opening.

Abstract
The invention relates to a heart valve prosthesis for percutaneous replacement of a tricuspid valve including a stent-type support structure and a biological heart valve; the stent-type support structure can autonomously expand from a radially compressed state into a radially expanded state and includes a fluid-tight cover which extends like a tube over at least some portions of the support structure; the heart valve is arranged in a lateral opening in the support structure. Embodiments further relate to a system including a heart valve prosthesis of said type.
