摘要： A device for percutaneously delivering a stented prosthetic heart valve. The device includes an inner shaft, a delivery sheath, stability tube, and a handle. The delivery sheath is slidably disposed over the inner shaft, and includes a capsule compressively containing the prosthesis over the inner shaft. The stability tube is coaxially received over the delivery sheath, and includes a distal region. A circumferential rigidity of the capsule is greater than a circumferential rigidity of the distal region. In transitioning from a delivery state to a deployed state, the capsule is withdrawn from the prosthetic heart valve and at least partially into the distal region to permit the prosthesis to self-deploy. The capsule forces the distal region to stretch and expand in diameter.

摘要： A delivery device for percutaneously deploying a stented prosthetic heart valve. The device includes a delivery capsule and a recapture sheath. The capsule is configured to compressively retain the prosthesis. The recapture sheath includes a funnel segment having a plurality of circumferentially spaced runners and a polymer overlay. The runners are attached to a shaft and terminate at a distal tip. The overlay surrounds the runners, and is bonded to the shaft but not to at least the tips. The funnel segment is transitionable from a normal condition to an expanded condition forming a funnel shape with a distally increasing diameter, and self-transitionable back toward the normal condition. The funnel segment facilitates sliding of the capsule over a partially deployed region of the prosthesis as part of a recapturing operation. The runners provide columnar strength, with the overlay controlling a shape of the funnel segment.

摘要： The present invention is directed to an improved delivery system to deliver and deploy a prosthesis in a body lumen, and methods of use thereof. The improved delivery system allows for operation of the delivery system with one hand while maintaining accuracy in delivery and deployment of the prosthesis. An exemplary embodiment of the delivery system includes a first sheath control on a housing so as to be accessible from the exterior of the housing, wherein the first sheath control is operatively engaged with the sheath and controls movement of the sheath axially proximally with respect to the housing, thereby releasing at least a portion of the prosthesis.

摘要： A tubular stent that uniformly scaffolds vessel tissue within a region that significantly changes diameter or transverse dimension. The invention may be practiced in lumens that taper in either retrograde or antegrade directions, and the transverse dimensional change may be relatively linear or flared. A catheter for delivering the stent of the invention may include a balloon having a comparably flared shape and an inverse conical distal end.

摘要： Systems and methods of delivering and retaining a leadless medical implant to tissue, wherein a docking base and the implant are sequentially delivered to an implantation site. In a first stage, the docking base is delivered and deployed into tissue at an implantation site. In a second stage, the implant is navigated through the vasculature and coupled to the docking base. Various mechanisms for navigating the implant to the previously implanted docking base and coupling the implant thereto are described. Navigational mechanisms include advancing the implant over a proximally extending wire portion that is releasably attached to the previously implanted docking base, utilizing fluoroscopic visualization to guide the implant to a previously implanted docking base that is at least partially radiopaque and utilizing electromagnetism to guide the implant to a previously implanted docking base that is electro-magnetizable.
