  • Patent number: 11241253
    Abstract: Subcutaneous implantation tools and methods of implanting a subcutaneous device using the same. The tool may include a tool body having a longitudinally extending recess having a distal opening and having a tunneler at a distal end of the tool body extending from the distal opening of the recess. The tool may include a plunger slidably fitting within at least a portion of the tool body recess. The recess may be configured to receive an implantable device and the tunneler preferably extends distally from the recess at a position laterally displaced from the device when the device is so located in the recess.

  • Patent number: 11229537
    Abstract: An introduction arrangement for a fenestrated or branched stent graft intended for deployment into the lumen of a vessel having a blind vessel extending from it. The introducer has a distal end intended to remain outside a patient in use and a proximal end with a nose cone dilator and an arrangement to retain the branched stent graft distally of the nose cone dilator. A sheath on the introducer extends over the branched stent graft to the nose cone dilator. An indwelling catheter extends from the distal end of the introducer and enters the fenestration or side arm and through to the nose cone dilator, the indwelling catheter has a guide wire extending through it. The guide wire can be extended beyond the nose cone dilator in use before the sheath is withdrawn from the branched stent graft so that it can be snared from the contra-lateral artery.

  • Patent number: 11224725
    Abstract: A trans-atrial septal catheter system for delivery of a steerable sheath into the left atrium contains three components. The first component is a three-segmented needle-guide wire composed of a distal needle designed to flex sharply in relation to the conjoined looped guide wire segment after fossa ovalis puncture and needle advancement. The distal guide wire loops are advanced into the left atrium maintaining the angled needle in a central location relevant to the loops for preserving an atraumatic position while stabilizing the loops in the left atrium. The elongated proximal extra stiff guide wire segment is conjoined to the looped segment which crosses the fossa ovalis and extends proximally to become externalized to the femoral vein. This segment is extra stiff and significantly elongated to permit catheter and device exchanges. The guide wire serves as a support rail over which the dilator and sheath can be advanced into the left atrium.
