The invention relates to a medical implant, comprising an expandable structure () which is designed to be expanded from a crimped state into an expanded state, wherein the structure () forms a tubular scaffolding in the expanded state, and wherein the structure () comprises a plurality of first struts () arranged along a periphery of the structure in said expanded state. According to the invention, the first struts () each comprise a recess (O), wherein the medical implant () further comprises a sealing member () arranged in said recesses (O), wherein said sealing member () is formed annularly in said expanded state.

Expandable annulus sealing ring for stented minimally invasive heart valve prostheses

A biological heart valve replacement, particularly for pediatric patients, comprises a tubular segment (A) comprising a proximal end (Ep), a distal end (Ed) and a central portion (Pc) arranged between said proximal and distal ends and defining a longitudinal direction of the valve. The valve further comprises at least one inner leaflet (C) attached in hinge-like manner to a connection zone (F) at an inner wall (W) region of said central portion, each one of said inner leaflets being movable between a closing position and an opening position of the valve. In order to provide growth adaptability, the tubular segment comprises at least one tubular growth zone (B; B,B) configured as a longitudinal strip made of a growth-adaptive biomaterial, with the remainder of the tubular segment being made of a non-growth-adaptive biomaterial.
