Abstract
An apparatus is usable for guiding and stabilizing a body implantable medical device. The apparatus includes a guide wire with an enlarged distal tip. The enlarged distal tip may include a compliant portion to prevent tissue abrasion or perforation. The implantable device includes an open lumen configured to longitudinally advance along the guide wire. A sleeve is disposed over the guide wire and slidably deployable over the enlarged tip of the guide wire. When the implantable device is in final position, the open lumen encompasses at least part of the enlarged tip of the guide wire. The sleeve can be moved over at least part of the enlarged tip and create an interference between the tip and the open lumen, thereby stabilizing the implantable device.
