The invention concerns the treatment of bioprosthetic tissues a Cyclodextrin, preferably in association with Ethanol.

Product and method for the treatment of bioprosthetic tissues

Prosthetic heart valve leaflet with a fixed end and a free end characterized by the fact that it has a variable thickness.

Prosthetic heart valve leaflet with variable thickness

An expandable stent-valve has a stent component and a valve component, preferably an aortic valve component, a mitral valve component or a tricuspid valve component. The stent has, an outer surface area structured in a manner such that the surface area has a higher coefficient of friction between the outer surface and a duct wall than an untreated surface area of the stent component. The surface area is preferably structured with micro-incisions or micro-grooves.

Expandable stent-valve and method for manufacturing a stent

Atrio-ventricular valve stent () having a tubular shape, with a sub annular anterior side (), a sub annular posterior side () and sub annular lateral sides (), the sub annular anterior side () comprising a self-folding native leaflet engagement member (-) that forms a straight extension of said sub annular anterior side () when the stent () is collapsed and that is folded on itself when the stent () is in an expanded state; said engagement member (-) forming an integral part of the stent () and wherein each sub annular lateral side () is longer than said sub annular anterior side () when the stent () is in an expanded state.

Atrio-ventricular valve stent with native leaflet grasping and holding mechanism

A cardiac stent-valve (), preferably a mitral stent-valve, comprising a stent component () and a valve component (), wherein the stent component () comprises an inflow end () and an outflow end () and a wall between the inflow () and the outflow end (), and wherein the valve component () is made of one single leaflet (); the periphery of said single leaflet () being partially attached or attachable to the stent component () along at least fixation lines (), characterized in that said two fixation lines (') are at least partially inclined with respect to an annular plane of said valve perpendicular to a flow direction (A) through the stent-valve () and wherein the third fixation line (&#x2033;) runs parallel with respect to said plane.

Cardiac stent-valve and delivery device for such a valve

A prosthetic valve, preferably an expandable prosthetic valve, having a valve component (), preferably a mitral valve component, made of a single functional leaflet () wherein the prosthetic valve () comprises at least two tissue supports (&#x2033;&#x2033;) attachable to an inner surface () of a stent component (), wherein at least one tissue support (&#x2033;&#x2033;) comprises at least one attachment area (&#x2033;), at least a section of the attachment area extending essentially inwardly from the inner surface (), wherein said leaflet () is attached to at least one tissue support ('&#x2033;) at the section of said attachment area(s) (&#x2033;) such that the leaflet () is arranged between said attachment area(s) (&#x2033;) or integrally formed with one tissue support (&#x2033;&#x2033;) and attached to the second tissue support (&#x2033;&#x2033;) at the section of the attachment area(s) (&#x2033;).

Prosthetic monoleaflet valve and delivery device

Medical device for transcatheter heart valve repair comprising a grasping tweezer () and a plicating tweezer (), said grasping tweezer () being adapted to grasp a leaflet rim () and said plicating tweezer () comprising two rotatable flaps () and a central shaft () around which said flaps () may rotate in a 'butterfly manner', in such a way that the plicating tweezer () may adopt a closed or an open configuration. The invention also relates to a method for using this medical device.

Device and method for transcatheter heart valve repair under triangular resection technique

Heart valve prosthesis, comprising a ring-shaped supporting structure () to be anchored at the valve annulus, and a valve leaflet () supported by the supporting structure. The supporting structure comprises a support wall portion (), at which a root end () of the valve leaflet is connected, and a complementary wall portion () opposite the support wall portion, which supports a coaptation surface () adapted to be sealingly engaged by a free end () of the valve leaflet (), and extending in a direction parallel to the direction of movement of the free end () of the valve leaflet () at the coaptation surface (). The free end of the valve leaflet () is connected to the support wall portion or to the complementary wall portion by means of a traction member (), dimensioned in such a way that the free end () of the valve leaflet () is stopped at the coaptation surface.
