Self-expandable medical instrument for treating defects in a patient's heart
First Claim
1. A replacement valve for use within a human body comprising:
- a valve component; and
a stent component comprising a first section having a first state during insertion of the stent component and a second, laterally-inverted inside-out state when deployed, a second section for housing the valve component, and a third section,wherein the first section, when in the second, laterally inverted inside-out state, is configured to be positioned on a first side of a leaflet of a native valve radially outward of the leaflet and radially inward of a vessel wall when the third section is positioned on a second side of the native valve, opposite the first side, andwherein the second section has a cross sectional size smaller than the cross sectional size of the first section and the cross sectional size of the third section.

Abstract
The invention relates to a self-expandable medical instrument (100) for treating defects in a patient'"'"'s heart, in particular for the transvascular implantation of a prosthetic heart valve (30), wherein the medical instrument (100) is introducible into the body of a patient in a minimally-invasive procedure using a catheter system (40) and comprises a stent (1) made of a flexible mesh (2) of thin wires or filaments (2′). In order to realize a positioning of medical instrument (100) in the patient'"'"'s heart which is as precise as possible and to securely anchor same there, it is provided for the stent (1) composed of the flexible mesh (2) to exhibit in the expanded state of the medical instrument (100) a distal retention area (10) with a laterally-inverted beaded portion (12) which is engageable in at least one pocket (51) of the patient'"'"'s defective heart valve (50), a proximal retention area (20), and a center area (15) positioned between the distal and the proximal retention area (10, 20).

23. A medical device, comprising:
-
a valve component; and a stent component, including; a first portion supporting the valve component, a second portion connected at a distal end of the first portion having a first state during insertion of the stent component and a second, laterally-inverted inside-out state when deployed, at least a part of the second portion, when in the second, laterally inverted inside-out state, configured to be positioned on a first side of a native valve radially outward of a valve leaflet and radially inward of a vessel wall, and a third portion connected at a proximal end of the first portion, at least a part of the third portion configured to be positioned on a second side of the native valve, opposite the first side such that the valve leaflet is clamped by the part of the second portion positioned on the first side of the native valve and by the part of the third portion positioned on the second side of the native valve. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A medical device, comprising:
-
a valve component; and a stent component including a distal section having a first state during insertion of the stent component and a second, laterally-inverted inside-out state when deployed, proximal section, and a middle section disposed between the distal and proximal sections and supporting the valve component; wherein a portion of the distal section, when in the second, laterally inverted inside-out state, is configured to be positioned on a first side of a native valve radially outward of a valve leaflet and radially inward of a vessel wall, a portion of the middle section is configured to be positioned within the annulus of the native valve, and a portion of the proximal section is configured to be positioned on a second side of the native valve, opposite the first side; and wherein the valve leaflet is clamped by the portion of the distal section positioned on the first side of the native valve and by the portion of the proximal section positioned on the second side of the native valve. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)
