Valve leaflet attachment in collapsible prosthetic valves
A prosthetic heart valve includes a stent having a collapsed condition and an expanded condition. The stent includes a plurality of cells, each cell being formed by a plurality of struts, and a plurality of commissure features. The heart valve further includes a valve assembly secured to the stent and including a cuff and a plurality of leaflets, each leaflet being attached to adjacent commissure features and to the stent struts and/or the cuff.
Minimally-invasive heart valve with cusp positioners
A prosthetic heart valve includes a support frame and a plurality of leaflets disposed inside the support frame. The support frame extends between an inflow end and an outflow end and includes a leaflet frame and a plurality of positioning members coupled to the leaflet frame. The leaflet frame has an undulating shape at the outflow end of the support frame and includes a plurality of commissure regions spaced apart from each other. The positioning members are disposed between the commissure regions of the leaflet frame and extend radially outwardly relative to the leaflet frame. The positioning members are configured to contact native tissue and anchor the support frame relative to the native tissue. The leaflets are coupled to the commissure regions of the leaflet frame. The leaflets are configured to allow flow in a first direction and to substantially block flow in an opposite direction.
Valve apparatus, system and method
A venous valve with a frame and a cover on the frame for unidirectional flow of a liquid through the valve.
Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods
Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having an upstream portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.
DEVICE FOR CARDIAC VALVE REPAIR AND METHOD OF IMPLANTING THE SAME
A device for cardiac valve repair, the device comprising: a stent adapted to anchor to at least one tissue site, the tissue site located upstream with respect to a heart valve of a patient; and a neo-leaflet arranged to extend from the upstream anchoring means, the neo-leaflet comprising a free end, wherein the neo-leaflet is operable to extend across the heart valve via a commissure in between two heart valve leaflets of the patient's heart and locate the free end downstream from the heart valve and the neo-leaflet operable to coapt with the heart valve leaflets of the patient's heart to prevent and/or minimize a backflow of blood. The present invention is suitable for the treatment of heart valves using minimally invasive approaches. Additionally, the present invention is directed to a method of implanting a device for cardiac valve repair in a patient's heart.
Prosthetic heart valve devices, prosthetic mitral valves and associated systems and methods
Devices and methods for implantation at a native mitral valve having a non-circular annulus and leaflets. One embodiment of the device includes a valve support having a first region configured to be attached to a prosthetic valve with a plurality of prosthetic leaflets and a second region. The device can further include an anchoring member having a longitudinal dimension and including a first portion configured to contact tissue at the non-circular annulus, a second portion configured to be attached to the valve support, and a lateral portion between the first portion and the second portion. The second portion of the anchoring member is attached to the second region of the valve support while in a low-profile configuration in which the anchoring member and the valve support are configured to pass through vasculature of a human. The lateral portion is transverse to the longitudinal dimension. The anchoring member and the valve support are configured to move from the low-profile configuration to an expanded configuration in which the first portion of the anchoring member at least partially adapts to the non-circular annulus of the native mitral valve and the first region of the valve support is spaced inwardly from the first portion of the anchoring member relative to the longitudinal dimension of the anchoring member such that a shape of the first region of the valve support is at least partially independent of a shape of the first portion of the anchoring member.
Venous valve, system and method
A venous valve with a frame and a cover on the frame for unidirectional flow of a liquid through the valve.
MINIMALLY-INVASIVE HEART VALVE WITH CUSP POSITIONERS
A prosthetic heart valve includes a support frame and a plurality of leaflets disposed inside the support frame. The support frame extends between an inflow end and an outflow end and includes a leaflet frame and a plurality of positioning members coupled to the leaflet frame. The leaflet frame has an undulating shape at the outflow end of the support frame and includes a plurality of commissure regions spaced apart from each other. The positioning members are disposed between the commissure regions of the leaflet frame and extend radially outwardly relative to the leaflet frame. The positioning members are configured to contact native tissue and anchor the support frame relative to the native tissue. The leaflets are coupled to the commissure regions of the leaflet frame. The leaflets are configured to allow flow in a first direction and to substantially block flow in an opposite direction.
Multilayer luminal endoprosthesis and manufacturing method
A luminal endoprosthesis (1) at least partially delimits a prosthesis lumen (2), for implantation in an anatomical structure (3) that at least partially defines at least one cavity (4) and includes a pathological portion (13). The luminal endoprosthesis (1) includes two or more layers (5, 6, 7), at least one layer (5, 6, 7) having at least one threadlike element (8) forming an armor (9). The luminal endoprosthesis (1) includes an anchoring portion (10), for anchoring to an anatomical portion (11) of the walls of the cavity (4) of the anatomical structure (3). A working portion (12) faces the pathological portion (13) of the anatomical structure (3). The two or more layers (5, 6, 7) are separated from each other at least in the working portion (12) of the luminal endoprosthesis (1), avoiding connecting elements between one layer (5, 6, 7) and at least one adjacent layer.
Systems and methods for measuring volume of potential sleeve in a sleeve gastrectomy
One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.
