  • Patent number: 11819629
    Abstract: A catheter shaft includes an inner layer defining an innermost circumferential surface of the catheter shaft and defining a lumen of the catheter shaft, and an outer layer defining an outermost circumferential surface of the catheter shaft. The inner layer is formed by a first polymer having a first durometer and a first melting temperature. The outer layer is formed by alternating first and second segments of the first polymer and a second polymer, respectively, that alternate in a circumferential direction. The second polymer has a second durometer softer than the first durometer and a second melting temperature lower than the first melting temperature. Each segment of the alternating first and second segments extend in an axial direction for substantially an entire length of the catheter shaft. A method of forming the catheter shaft via extrusion is also disclosed.

  • Patent number: 11690713
    Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments.

  • Patent number: 11622858
    Abstract: A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.

  • Patent number: 11284997
    Abstract: A heart valve prosthesis is provided having a self-expanding multi-level frame that supports a valve body comprising a skirt and plurality of coapting leaflets. The frame transitions between a contracted delivery configuration that enables percutaneous transluminal delivery, and an expanded deployed configuration having an asymmetric hourglass shape. The valve body skirt and leaflets are constructed so that the center of coaptation may be selected to reduce horizontal forces applied to the commissures of the valve, and to efficiently distribute and transmit forces along the leaflets and to the frame. Alternatively, the valve body may be used as a surgically implantable replacement valve prosthesis.

  • Patent number: 11166815
    Abstract: A catheter that comprises a sheath that is connected at opposing ends to concentric tubes that move relative to each other in a manner that alternatively covers and exposes a medical device loaded onto the catheter. A portion of the sheath is arranged so as to invert upon itself so that axial movement of one tube relative to the other simultaneously moves the inversion point over or away from the device, alternatively covering or exposing the device.

  • Patent number: 10478302
    Abstract: This material comprises an annuloplasty member able to be introduced using a catheter through minimally invasive vascular access, then to be delivered by said catheter and fixed to the valve annulus. According to the invention, it includes at least one catheter comprising at least one guide member able to be deployed from said catheter such that it extends along one portion of the valve annulus of the valve, in the immediate proximity of said valve annulus, and an implant having a helical shape engaged on said guide member, connected, with separation possibility, to actuation means making it possible to cause this implant to move forward while driving it in rotation around its axis; the implant can thus be deployed from the catheter while being simultaneously moved forward and driven in rotation along its axis.
