Pass-through implantable medical device delivery catheter with removeable distal tip
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 and a proximal opening, the outer sheath sized to traverse a vasculature of the patient;
an elongated inner sheath with a tapered distal end, wherein the tapered distal end is configured to substantially fill the inner lumen of the outer sheath and close-off the distal opening of the outer sheath, wherein the inner sheath is slidable within the inner lumen of the outer sheath, wherein the inner sheath is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath; and
an elongated deployment receptacle including a deployment bay at a distal end of the deployment receptacle and a proximal portion, wherein the deployment receptacle is slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath, wherein the deployment bay is configured to carry the implantable medical device through the inner lumen of the outer sheath and facilitate deployment of the implantable medical device out of the distal opening of the outer sheath, wherein the deployment bay includes a proximal wall that limits proximal movement of the implantable medical device relative to the elongated deployment receptacle while the implantable medical device is carried within the deployment bay, wherein a transverse cross section of the proximal portion is smaller than a transverse cross section of the deployment bay.

Abstract
In one example, this disclosure is directed to a kit for intravascular implantation of an implantable medical device, the kit comprising an outer sheath, the outer sheath sized to traverse a vasculature of the patient, and an elongated inner sheath with a tapered distal end. The inner sheath is slidable within the inner lumen of the outer sheath and is selectably removable from the inner lumen of the outer sheath by sliding the inner sheath out of the proximal opening of the outer sheath. The kit includes an elongated deployment receptacle including a deployment bay slidable within the inner lumen of the outer sheath when the inner sheath is not within the inner lumen of the outer sheath. The deployment bay carries an implantable medical device through the inner lumen of the outer sheath and facilitates deployment of the implantable medical device from the distal end of the outer sheath.

16. A method for intravascular implantation of an implantable medical device within a patient comprising:
-
positioning a distal end of an elongated outer 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 and a proximal opening; inserting an elongated deployment receptacle, including a deployment bay at a distal end of the deployment receptacle and a proximal portion, into the proximal opening of the outer sheath, wherein the implantable medical device is positioned within deployment bay, wherein the deployment bay includes a proximal wall that limits proximal movement of the implantable medical device relative to the elongated deployment receptacle while the implantable medical device is within the deployment bay, wherein a transverse cross section of the proximal portion is smaller than a transverse cross section of the deployment bay; sliding the deployment receptacle through the inner lumen of the outer sheath until the deployment bay is adjacent to the distal opening of the outer sheath; and deploying the implantable medical device from the deployment bay proximate to the target site within the patient. - View Dependent Claims (17, 18, 19, 20, 21, 22)
