Abstract
Apparatus and methods are described for use with a native tricuspid valve of a heart of a mammalian subject. A valve frame (22) includes a valve-frame body (32) that is configured to support prosthetic valve leaflets (20) within the native tricuspid valve. Chord-recruiting arms (30) are configured to extend from the valve-frame body at circumferential regions corresponding to the anterior leaflet and the posterior leaflet of the native tricuspid valve. An anchoring arm (28) is configured to extend from the valve-frame body at a circumferential region corresponding to the septal leaflet of the native tricuspid valve, the anchoring arm (28) being longer than each of the chord-recruiting arms (30). Other applications are also described.
Claims21
An apparatus for use with a native tricuspid valve of a heart of a mammalian subject, the native tricuspid valve including an anterior leaflet, a posterior leaflet, and a septal leaflet, and chords extending to each of the leaflets, the apparatus comprising:
- prosthetic valve leaflets;
- a valve frame, the valve frame comprising:
- a valve-frame body that is configured to support the prosthetic valve leaflets within the native tricuspid valve, the valve-frame body comprising an atrial portion configured to be deployed in a right atrium of the subject;
- chord-recruiting arms that are configured to extend from the valve-frame body at circumferential regions corresponding to the anterior leaflet and the posterior leaflet of the native tricuspid valve;
- an anchoring arm that is configured to extend from the valve-frame body at a circumferential region corresponding to the septal leaflet of the native tricuspid valve, the anchoring arm being longer than each of the chord-recruiting arms;
- and
- a coronary-sinus anchor that extends radially from the atrial portion of the valve-frame body, the coronary-sinus anchor being configured to be inserted into a coronary sinus of the subject and to thereby anchor the valve frame with respect to the native tricuspid valve.
An apparatus for use with a native tricuspid valve of a heart of a mammalian subject, the native tricuspid valve including an anterior leaflet, a posterior leaflet, and a septal leaflet, and chords extending to each of the leaflets, the apparatus comprising:
- prosthetic valve leaflets;
- a valve frame, the valve frame comprising:
- a valve-frame body that is configured to support the prosthetic valve leaflets within the native tricuspid valve, the valve-frame body comprising an atrial portion configured to be deployed in a right atrium of the subject;
- chord-recruiting arms that are configured to extend from the valve-frame body at circumferential regions corresponding to the anterior leaflet and the posterior leaflet of the native tricuspid valve, the valve frame not including any arms extending from the valve-frame body at a circumferential region corresponding to the septal leaflet of the native tricuspid valve;
- and
- a coronary-sinus anchor that extends radially from the atrial portion of the valve-frame body, the coronary-sinus anchor being configured to be inserted into a coronary sinus of the subject and to thereby anchor the valve frame with respect to the native tricuspid valve.

- prosthetic valve leaflets;
- a valve frame, the valve frame comprising:
- a valve-frame body that is configured to support the prosthetic valve leaflets within the native tricuspid valve, the valve-frame body comprising an atrial portion configured to be disposed in a right atrium of the subject;
- and
- a coronary-sinus anchor that extends radially from the atrial portion of the valve-frame body, the coronary-sinus anchor being configured to be inserted into a coronary sinus of the subject and to thereby anchor the valve frame with respect to the native tricuspid valve.
