IMPLANTABLE MEDICAL DEVICE DELIVERY CATHETER WITH TETHER
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 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, wherein the enlarged distal portion is slidable relative to the outer sheath,wherein 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.

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.

19. 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 enlarged distal portion, wherein the enlarged distal portion substantially fills the inner lumen to close-off the distal opening of the outer sheath, wherein the enlarged distal portion is slidable relative to the outer sheath, wherein the inner sheath further includes a tether with a helical element; and releasing an implantable medical device from a distal portion of the outer sheath by remotely rotating the helical element such that the helical element releases a looped element of the implantable medical device. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
