APPARATUS AND METHODS FOR TRANSFERRING AN IMPLANTED ELONGATE BODY TO A REMOTE SITE
First Claim
1. A device for manipulating an implantable lead member, comprising:
- a biocompatible elongate member having a first section and a second section;
wherein the first section comprises a pull member attachment interface and the second section comprises a selective coupling interface configured to selectively attach to a section of an implantable lead member.

Abstract
A transfer guidewire assembly configured to manipulate an implanted elongate body includes a flexible elongate portion, such as a guidewire, and coupler. The flexible elongate body has a proximal end and a distal end attached to the coupler. The coupler can include a catheter and/or a handle. The handle can include a screw. The coupler is configured to be removably attached to the end of an implanted elongate body, for example, by forming an interference fit with the outside diameter of the implanted body. A method for transferring an end of an implanted medical component from first site to a second site within a patient, such as a pacemaker, defibrillator, and/or sensor lead, etc., includes inserting a guidewire into the body at the first site and externalizing the guidewire at the second site. A proximal portion of the implanted component near the first site and is attached to the guidewire. The proximal portion of the implanted component is pulled through the patient'"'"'s body and out the second site with the transfer guidewire assembly.
