Tethered implantable medical device deployment

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, wherein the outer sheath sized to traverse a vasculature of the patient, and wherein the inner lumen is sized to hold the implantable medical device;
• an elongated inner sheath with a distal end, wherein the inner sheath is located within the inner lumen of the outer sheath;
• and
• a deployment handle located at proximal ends of the outer sheath and the inner sheath, wherein the deployment handle includes a sheath retraction mechanism that facilitates selectively retracting the outer sheath relative to the inner sheath to facilitate remote deployment of the implantable medical device out of the distal opening of the inner lumen of the outer sheath.

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, 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.
