  • Implantable medical device delivery catheter with tether
    Patent number: 9717421
    Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming an inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with an enlarged distal portion, wherein the enlarged distal portion is configured to substantially fill the inner lumen and close-off the distal opening of the outer sheath. The enlarged distal portion is slidable relative to the outer sheath. The inner sheath further includes a tether with a helical element that is remotely controllable from a proximal end of the inner sheath to release the implantable medical device from a distal portion of the outer sheath.
    Type: Grant

  • Intravascular implantable medical device introduction
    Patent number: 9339197
    Abstract: In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient, the kit comprising an elongated outer sheath forming an inner lumen with a distal opening, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with an inflatable member at its distal portion. The inflatable member is inflatable from a proximal end of the inner sheath to close-off the distal opening of the outer sheath when inflated. The inner sheath further includes a stopper proximally located relative to the inflatable member. The inflatable member is remotely controllable from a proximal end of the inner sheath to retract in a proximal direction towards the stopper. The inflatable member can be retracted in a proximal direction towards the stopper and past an implantable medical device positioned within a distal portion of the outer sheath.
