  • Patent number: 10123895
    Abstract: 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.

  • Publication number: 20170304097
    Abstract: A catheter for delivering a self-expanding stent-graft prosthesis includes an inner shaft component having a distal segment over which the stent-graft prosthesis is loaded in a compressed delivery configuration. The distal segment has a covering that is intimately disposed thereover. The covering forms a raised outer surface on the distal segment and includes a plurality of protrusions that extend radially outward from the raised outer surface. An outer shaft component is slidingly disposed over the distal segment of the inner shaft component for holding the stent-graft prosthesis in the compressed delivery configuration. In the compressed delivery configuration, the stent-graft prosthesis is disposed over and makes contact with the covering of the distal segment of the inner shaft component such that at least the plurality of protrusions provide sufficient friction to of the covering secure a longitudinal position of the stent-graft prosthesis relative to the inner shaft component.

  • Patent number: 9687344
    Abstract: A delivery system for percutaneously delivering and deploying a stented prosthetic heart valve. The delivery device includes a delivery sheath slidably disposed over an inner shaft, and a capture assembly. The capture assembly includes a spindle and a biasing member. The spindle is attached to the inner shaft and defines slot. The biasing member is disposed within the slot and self-transitions from a deflected condition to a normal condition. In a delivery state, the delivery sheath retains the prosthesis over the inner shaft and coupled to the spindle via the capture slot, including a portion of the prosthetic valve being engaged within the slot and the biasing member forced to the deflected condition. In a deployment state, the delivery sheath is proximally withdrawn and the biasing member self-transitions toward the normal condition to eject the prosthetic valve from the capture slot.

  • Patent number: 8512401
    Abstract: 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.

  • Patent number: 8491650
    Abstract: 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.

  • Publication number: 20110270339
    Abstract: 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.

  • Patent number: 7867269
    Abstract: 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. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
