Tethered implantable medical device deployment
First Claim
1. 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 a stopper configured engage a proximal side of the implantable medical device to preclude the implantable medical device from being located at a more proximal position than the stopper within the inner lumen of the outer sheath,wherein the inner sheath further includes a tether configured to form a loop on a distal side of the stopper, the loop being configured to engage a looped element of the implantable medical device to couple the implantable medical device to the inner sheath,wherein a first end of the tether is fixed to the stopper, wherein a second end of the tether includes a bead, wherein the bead is located within the inner lumen of the elongated outer sheath proximal to the stopper when the tether forms the loop,wherein the stopper is slidable relative to the outer sheath between a position that is proximally located relative to the distal opening of the outer sheath and a position in which at least a portion of the stopper is distally located relative to the distal opening of the outer sheath,wherein the tether is configured to release the looped element of the implantable medical device from the inner sheath by opening the tether loop when the at least a portion of the stopper is located distally relative to the distal opening of the outer sheath.

Abstract
In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device within a patient 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 a stopper. The inner sheath further includes a tether configured to form a loop on a distal side of the stopper, the loop being configured to engage a looped element of the implantable medical device to couple the implantable medical device to the inner sheath. The stopper is slidable relative to the outer sheath. The tether is configured to release the looped element of the implantable medical device from the inner sheath by opening the tether loop when a portion of the stopper is located distally relative to the distal opening of the outer sheath.

23. A method for intravascular implantation of an implantable medical device within a patient comprising:
-
positioning a distal end of an assembly including an elongated outer sheath and an elongated inner sheath via a vasculature of the patient proximate to a target site within the patient, wherein the outer sheath forms an inner lumen with a distal opening, wherein the inner sheath includes a stopper configured to engage a proximal side of the implantable medical device to preclude the implantable medical device from being located at a more proximal position than the stopper within the inner lumen of the outer sheath, wherein the inner sheath further includes a tether forming a loop on a distal side of the stopper, wherein a first end of the tether is fixed to the stopper, wherein a second end of the tether includes a bead, wherein the bead is located within the inner lumen of the elongated outer shealth proximal to the stopper when the tether forms the loop, the loop being in engagement with a looped element of the implantable medical device to couple the implantable medical device to the inner sheath within the inner lumen of the outer sheath; and retracting the outer sheath relative to the inner sheath such that the implantable medical device exits the inner lumen via the distal opening. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
