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, wherein the outer sheath is configured to receive the implantable medical device within the inner lumen; and
an elongated inner sheath with an enlarged distal portion, wherein the enlarged distal portion includes an inflatable member that is configured to substantially fill the inner lumen and close-off the distal opening of the outer sheath when inflated, 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,wherein the inner sheath further includes a stopper proximally located relative to the inflatable member, wherein the inflatable member is remotely controllable from a proximal end of the inner sheath to retract in a proximal direction towards the stopper while the stopper is stationary,wherein the kit is configured such that the inflatable member can be retracted in the proximal direction and towards the stopper while the stopper is stationary and past the implantable medical device positioned within the distal portion of the outer sheath, andwherein the implantable medical device includes at least one of a stimulation electrode, a sensing electrode, a battery, or a sensor.

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.

18. 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 implantable medical device is disposed within a distal portion of the outer sheath, wherein the inner sheath includes enlarged distal portion, wherein the enlarged distal portion includes an inflatable member that substantially fills the inner lumen to close-off the distal opening of the outer sheath when inflated, wherein the inflatable member is selectively inflatable from a proximal end of the inner 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; deflating the inflatable member; retracting the inflatable member in a proximal direction past the implantable medical device that is positioned within the distal portion of the outer sheath; and releasing the implantable medical device from the 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, wherein the implantable medical device includes at least one of a stimulation electrode, a sensing electrode, a battery or a sensor. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
