  • Patent number: 10799350
    Abstract: Devices and methods for retrieving percutaneously implanted catheter systems such as a heart valve repair system. The devices include at least one locking connector at the distal end of a flexible elongated extension for coupling to an implanted tubular member. The locking connector may be a tubular anchor having a pair of distal prongs which are biased outward and face in a proximal direction, as well as an expandable auxetic midsection. Inserting the tubular anchor into the implanted tubular member flexes the distal prongs inward such that they prevent proximal movement of the tubular anchor. A user pulls on the proximal end of the tubular anchor to expand the auxetic midsection and lock the two pieces together. The devices and methods are particularly useful to attach extensions to implanted concentric tubes to enable relative axial force application.

  • Patent number: 10792468
    Abstract: An endovascular guide catheter includes a guide tube and a handle. The flexible guide tube has a distal end portion configured to deflect via actuation of a pull wire. The handle is coupled to the guide tube and comprises a steering assembly configured to actuate the pull wire to deflect the distal end portion of the guide tube. The steering assembly can comprise a stationary rack, a gear, a reel, and a slider. The gear engages the rack and the reel is coupled to and configured to rotate with the gear. The pull wire is coupled to the reel such that rotation of the reel causes the pull wire to wind or unwind around the reel. The slider is adapted for translation relative to the rack. Translation of the slider translates the reel relative to the rack and rotation of the gear along the rack rotates the reel.

  • Patent number: 10751208
    Abstract: An implant delivery system includes a delivery catheter and a delivery mechanism slidably disposed in a lumen of the delivery catheter. The delivery mechanism includes an annular channel and a compressible annular bushing disposed within the annular channel. The annular bushing is configured for being placed between a compressive profile and an expanded profile. The implant delivery system further includes an implant coaxially disposed between the delivery catheter and the delivery mechanism. The delivery catheter lumen is sized to maintain an engagement element of the implant within the annular channel and to urge the annular bushing into the compressive profile. The implant constrains a distal tip of the delivery mechanism to assume a straight geometry. The distal tip is configured for assuming a curved geometry when the implant is deployed from the delivery catheter.

  • Patent number: 10716690
    Abstract: A system for deploying a prosthesis over a Carina between an ipsilateral lumen and a contralateral lumen includes a guidewire, a guidewire capture catheter, a self-expanding tubular prosthesis, and a delivery catheter. The guidewire is first placed in the ipsilateral lumen. The guidewire capture catheter is then advanced from the contralateral lumen to a position at or above the ipsilateral lumen. The guidewire is typically advanced through an occlusion, which may be a total occlusion, and captured by a capture element on the guidewire capture catheter. The guidewire capture catheter pulls the guidewire out through the contralateral side, and the guidewire is used to advance a delivery catheter from the ipsilateral side. The delivery catheter delivers a first segment of the tubular prosthesis in the ipsilateral lumen and a second segment of the prosthesis in the contralateral lumen.
