Replacement heart valve with reduced suturing
A heart valve replacement device comprises a stent having a first end, a second end, an outer surface, and an inner surface, the inner surface defining a lumen; and a valve disposed within the lumen of the stent, the valve formed from a single sheet of tissue, the valve having an outer surface, an inner surface, and a thickness between the outer surface and the inner surface, the valve comprising at least three leaflets, wherein, the valve is attached to the stent with minimal sutures. The leaflets are formed with a curvilinear surface.
Methods of assembling valved aortic conduits
A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.
Braided anchor for mitral valve
A prosthetic heart valve may include a valve portion, a tether connected to the valve portion, and an anchor for connecting the tether to the wall of the heart. The anchor may include a flexible first disc biased toward a first shape that is convex in a first direction and a neck extending from the first disc in a second direction opposite the first direction. The neck has a first end connected to the first disc and a second end. The anchor may further include a flexible second disc connected to the second end of the neck and biased toward a second shape that is convex in the first direction. When deployed, the first and second discs sandwich the wall of the heart.
LEAFLET ATTACHMENT CONFIGURATIONS TO THE FRAMES OF PROSTHETIC VALVES
The present invention relates to implantable prosthetic devices, such as prosthetic heart valves, and to attachment configurations and methods of attaching soft components, such as leaflets or skirts, to frames of such prosthetic valves.
Low profile transcatheter heart valve
An implantable prosthetic valve includes a radially collapsible and expandable annular frame having three commissure attachment posts and four rows of circumferential struts. The rows include a first row, a second row downstream of the first row, a third row downstream of the second row, and a fourth row downstream of the third row and defining an outflow end of the frame. Each row of circumferential struts includes angled struts arranged in a zig-zag pattern. A leaflet structure includes three leaflets forming three commissures, each commissure being connected to one of the commissure attachment posts only at locations along the commissure attachment posts between a first plane that is perpendicular to a longitudinal axis of the frame and intersects crowns of the third row of struts and a second plane that is perpendicular to the longitudinal axis and intersects crowns of the fourth row of struts.
PROSTHETIC HEART VALVE AND TRANSCATHETER DELIVERED ENDOPROSTHESIS COMPRISING A PROSTHETIC HEART VALVE AND A STENT
The invention relates to a prosthetic heart valve (100) for an endoprosthesis (1) used in the treatment of a stenotic cardiac valve and/or a cardiac valve insufficiency. The prosthetic heart valve (100) comprises of a plurality of leaflets (102), which consist of a natural and/or synthetic material and have a first opened position for opening the heart chamber and a second closed position for closing the heart chamber, the leaflets (102) being able to switch between their first and second position in response to the blood flow through the heart. In addition, the prosthetic heart valve (100) comprises a leaflet support portion (103), consisting of biological and/or synthetic material for mounting of the prosthetic heart valve (100) to a stent (10), and a bendable transition area (104) which forms a junction between the leaflets (102) and the leaflet support portion (103), the transition area (104) progressing essentially in a U-shaped manner similar to a cusp shape of a natural aortic or pulmonary heart valve for reducing tissue stresses during opening and closing motion of the leaflets (102). The invention further relates to an endoprosthesis (1) comprising a prosthetic heart valve (100) and a stent (10).
DEVICES, SYSTEMS AND METHODS FOR USING AND MONITORING MEDICAL DEVICES
Medical devices are provided, comprising a medical device and a sensor.
Two Component Mitral Valve System Methods
A method for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.
Storage Devices, Loading Devices, Delivery Systems, Kits, and Associated Methods
Storage devices, loading devices, delivery systems, kits, and associated methods for implantable medical devices are described. An example embodiment of a storage device includes a storage member, a first cap, and a second cap. The storage member has a first end, a second end, and a main body that defines a first opening, a second opening, a passageway, a separating wall, and a plurality of holes. The passageway has a first portion and a second portion. The first portion extends from the first end of the storage member to the separating wall and the second portion extends from the second end of the storage member to the separating wall. Each hole of the plurality of holes extends through the separating wall and provides access between the first portion and the second portion. Each of the first and second caps is releasably attached to the storage member.
PROSTHETIC VALVE DEVICE FOR TREATMENT OF MITRAL VALVE INSUFFICIENCY
The present invention concerns a prosthetic valve device for treatment of mitral valve insufficiency, as well as methods of manufacturing the device. The device comprises a main body with a flexible stent frame and a prosthetic material covering the stent frame at least partially, and a valve structure, wherein the valve structure is formed by wire-elements having elongated loop-structures with prosthesis material attached thereto.
