Prosthetic valve with leaflet connectors

In an unfolded state, a sheet defines a panel at a medial region, and tab portions disposed peripherally to the panel. A method comprises (a) sandwiching, between a first tab portion and a second tab portion, (i) a first commissural portion of a first leaflet, and (ii) a second commissural portion of a second leaflet; (b) attaching the first tab portion and the second tab portion to the sheet by stitching a first stitching through the tab portions and the commissural portions; (c) subsequently, covering the first stitching by: (i) forming the first tab portion into a first tab having an outer layer and an inner layer, and (ii) forming the second tab portion into a second tab having an outer layer and an inner layer; and (d) subsequently, stitching a second stitching through the outer and inner layers, and the commissural portions. ... Mitraltech Ltd

Prosthetic valve and upstream support therefor

A prosthetic valve comprises a valve body, comprising a tubular frame and a plurality of leaflets; an upstream support, comprising a second frame; and a flexible sheet that couples the upstream support to the valve body. The prosthetic valve is compressible into a delivery tool such that the prosthetic valve is in a compressed state in which the second frame and the tubular frame are arranged in series within the tool, and the valve body has a compressed body-diameter. ... Mitraltech Ltd

Techniques for securing prosthetic valves using helical anchors

A distal portion of a catheter is transluminally advanced to a heart of a subject. Via an atrium of the heart, a ventricular anchor-helix is transluminally advanced out of the distal portion of the catheter to a ventricular site in a ventricle of the heart. ... Mitraltech Ltd

Anchoring of a prosthetic valve

A prosthetic valve is advanced to a heart of a subject while the prosthetic valve is in a compressed state thereof, the prosthetic valve including a plurality of snares coupled to a tubular valve body. The prosthetic valve is positioned within the heart such that the plurality of snares is disposed upstream of the leaflets, and the plurality of snares is expanded upstream of the leaflets. ... Mitraltech Ltd

Prosthetic valve with axially-sliding frames

A tubular portion (32) of a valve frame (30) circumscribes a longitudinal axis, and defines a lumen along the axis and a plurality of valve-frame coupling elements (31) disposed circumferentially around the axis. An outer frame (60): (a) comprises a ring (66) defined by a pattern of alternating peaks and troughs, the pattern having an amplitude, (b) comprises a plurality of legs (50), coupled to the ring at respective troughs, and (c) is shaped to define a plurality of outer-frame coupling elements (61), each coupled to the ring at a respective peak, and fixed with respect to a respective valve-frame coupling element. ... Mitraltech Ltd

Prosthetic heart valve with compressible frames

A tubular portion of a valve frame circumscribes a longitudinal axis, and defines a lumen along the axis and a plurality of valve-frame coupling elements disposed circumferentially around the axis. An outer frame: (a) comprises a ring defined by a pattern of alternating peaks and troughs, the pattern having an amplitude, (b) comprises a plurality of legs, coupled to the ring at respective troughs, and (c) is shaped to define a plurality of outer-frame coupling elements, each coupled to the ring, and fixed with respect to a respective valve-frame coupling element. ... Mitraltech Ltd

Techniques for percutaneous mitral valve replacement and sealing

A transluminal sheath is advanced transfemorally into a left atrium of a heart of the subject. A surrounding-sheath is advanced out of a distal end of the transluminal sheath, into the atrium, and toward a commissure of the mitral valve. ... Mitraltech Ltd

Techniques for deployment of a prosthetic valve

A delivery tool includes a delivery capsule, disposed at a distal portion of the tool. The delivery capsule includes a proximal capsule-portion dimensioned to house a first part of an implant, and a distal capsule-portion dimensioned to house a second part of the implant; and an extracorporeal control portion, disposed at a proximal portion of the tool, the control portion including one or more controllers and one or more locks. ... Mitraltech Ltd

Articulatable prosthetic valve

A rod (508) is transfemorally advanceable to the heart. An implant (460) comprises (i) a first frame (462), compressed around a first longitudinal site of a distal portion of the rod, (ii) a second frame (464), compressed around a third longitudinal site of the distal portion, (iii) a valve member (50), disposed within the second frame, and (iv) a flexible sheet (466), coupling the first frame to the second frame, and disposed around a second longitudinal site of the distal portion, the second longitudinal site being between the first longitudinal site and the third longitudinal site. ... Mitraltech Ltd

Rolled prosthetic valve support

Apparatus is provided for use at a native valve of a heart of a subject. The apparatus includes a delivery tube, transluminally advanceable to the heart; and a prosthetic valve support, configured to support a prosthetic valve at the native valve, and comprising an upstream support portion. ... Mitraltech Ltd

Techniques for providing a replacement valve and transseptal communication

A method is provided, comprising: (1) making a transapical puncture into a left ventricle of the heart; (2) making a transseptal fenestration in the heart; (3) delivering a prosthetic valve via the transapical puncture and implanting the prosthetic valve at a mitral valve of the heart; and (4) subsequently to delivering the prosthetic valve and making the transseptal fenestration, closing the transapical puncture. Other embodiments are also described.. ... Mitraltech Ltd

03/09/17 / #20170065407
