A delivery device for a stented heart valve includes a handle, an elongate shaft extending from a distal end of the handle, and a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

Surgical delivery device and method of use

A delivery device for a stented heart valve comprises a handle, an elongate shaft extending from a distal end of the handle, and a conical housing having a proximal end coupled to the elongate shaft and an open distal end, the conical housing having a conical lumen therein with a first internal diameter adjacent to the proximal end of the conical housing and a larger second internal diameter adjacent to the open distal end of the conical housing.

A delivery device for a stented heart valve comprises a handle, an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal end, an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing at a distal end that is structured to receive the bumper element therein.

Transapical delivery device and method of use

A method and device for reducing paravalvular leakage upon implantation of a replacement heart valve is provided. The valve assembly includes a tissue or bioprosthetic heart valve attached to an anchoring structure. The anchoring structure includes an inlet rim that is substantially C-shaped in cross section to form a concave landing zone. The anchoring structure self-seats when implanted in the sinus of a patient with the proximal and distal ends of the C-shaped inlet rim pushed against the aorta to effectively prevent paravalvular leakage.

Anchoring structure with concave landing zone

A delivery device for a stented heart valve that includes a handle, an inner catheter shaft extending from the handle and having an enlarged bumper element at a distal end, an outer catheter shaft extending from the handle and slidably coupled around the inner catheter shaft, and a retraction mechanism for controlling longitudinal movement of the outer catheter shaft relative to the inner catheter shaft. The outer catheter shaft includes a generally cylindrical housing at a distal end that is structured to receive the bumper element therein.

A catheter system comprises a catheter having an elongate catheter shaft such that a portion of the catheter shaft proximal a stent retaining region defines at least one bend that is bent around the longitudinal axis of a vessel. The catheter also has a side branch guidewire housing, defining a side branch guidewire lumen, and a side branch guidewire that extends through the side branch guidewire lumen.

Twisting bifurcation delivery system

An implant holder for removably retaining an implant during an implantation procedure includes a holder device having a frame defining a chamber. The frame may be configured for removable retention of an implant, such as the flexible bioprosthetic heart valve, substantially within the chamber. The removable retention of the implant to the implant holder maintains the implant in an orientation and shape suitable for implantation.

Tool for implantation of replacement heart valve

The present invention relates to medical devices for implantation or insertion into body lumens, for example, catheters, guidewires, stents and aneurysm coils. The devices of the present invention comprise electrically actuated materials, such as electroactive polymers and piezoelectric and electrostrictive materials, which enhance or expand their functionality.
