A prosthesis for implantation at a native semilunar valve site of a subject can include a support structure configured such that in a first rotational disposition of the prosthesis with respect to the native semilunar valve, a tactile feedback sensation is provided to a user implanting the prosthesis.

Devices useful for implantation at a heart valve

A surgically implantable multiple orifice heart valve having a valve frame with at least two orifices, each of which can accommodate a tissue valve. The multiple orifice heart valve includes a stent frame having a first side, an opposite second side, and multiple orifices or opening, each of which extends from the first side to the second side of the stent frame and is adjacent to at least one of the other multiple orifices or openings.

Multiple orifice implantable heart valve and methods of implantation

Described is a delivery system for minimally invasive delivery of a self-expandable stent to a body lumen, and particularly delivery of a prosthetic valve to the right ventricular outflow tract. Also described is a method of loading a stent onto such a delivery system, and a method of delivering a self-expandable stent to a desired anatomic site.

Infundibular reducer device delivery system and related methods

A device useful for implantation at a native heart valve can include an anchor element having a tubular configuration defining a longitudinal direction and a circumference, a heart valve prosthesis disposed within the anchor element, and a plurality of elongate members positioned at equidistant angular intervals about the circumference of the anchor element. The device can be configured to be transitioned from a radially collapsed delivery configuration to a radially expanded implantation configuration, and the plurality of elongate members can have a length extending in the longitudinal direction of the tubular member in the expanded implantation configuration.

A replacement prosthetic heart valve for engagement with a structure of a previously implanted prosthetic heart valve. The replacement heart valve includes a stent structure including a generally tubular body portion with an interior area and a series of wire portions arranged in a mesh-like configuration, and at least one stent post engaging structure extending radially outwardly from the body portion for engaging with an outer surface of a stent post of the previously implanted prosthetic heart valve. The stent structure further includes at least two leaflets attached within the interior area of the tubular body portion of the stent structure.

Replacement prosthetic heart valves and methods of implantation

A prosthetic valve including a replacement valve having a tubular valve body wall, an expandable stent having a framework with first and second ends, and suturing holding the framework to the valve body at the first and second ends. The suturing at the first end is colored differently from the suturing at the second end.

Apparatus for treatment of cardiac valves and method of its manufacture

A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.

Prosthetic heart valve systems

A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.

System and method for implanting a replacement valve

Described is a prosthetic valve assembly comprising: a radially self-expandable stent configured to expand to bear against a wall of a native body lumen; and an implantable prosthetic valve, having a diameter, the valve being mounted inside the stent; wherein the diameter of the stent is greater than the diameter of the prosthetic valve.

Infundibular reducer devices

System for implanting a replacement valve

The implant implantation unit (), at a determined position in the tubular element () with a wall comprising a cavity (), is pushed there by a catheter () and the unit comprises deformable feelers () to, under the control of remote activation elements (), change from a stowed form to a deployed functional form, to detect the cavity () and position itself there with reference to the position of the cavity.
