Insertion system for implanting a medical device and surgical methods
First Claim
1. An insertion system for an implantable medical device comprising:
- a guide wire having an outer surface;
an implantable medical device having a first inner surface, said first inner surface defining a first bore adapted for receiving said guide wire therethrough, whereby said guide wire and said implantable medical device are rotationally locked when said guide wire is received through said first bore; and
an insertion tool having a second inner surface, said second inner surface defining a second bore adapted for receiving said guide wire therethrough, whereby said guide wire and said insertion tool are rotationally locked when said guide wire is received in said second bore;
wherein said implantable medical device and said insertion tool are independently axially moveable along said guide wire.

Abstract
The present invention relates to an insertion system for medical devices and to surgical methods for the implantation of the same. In one embodiment, the implantation system includes a guide wire and an insertion tool. The insertion tool includes a longitudinal bore extending therethrough for receipt of the guide wire. A portion of the longitudinal bore of the insertion tool mates with the outer surface of the guide wire to rotationally lock the insertion tool and the guide wire. Additionally, the medical device to be inserted includes a longitudinal bore for receipt of the guide wire. Similarly, at least a portion of the longitudinal bore of the medical device may also mate with the outer surface of the guide wire to rotationally lock the medical device and the guide wire. The rotational locks allow for rotation of the insertion tool to result in corresponding rotation of the medical device via rotation of the guide wire. In another embodiment, the insertion system further includes a needle having an eyelet for receiving and positioning filaments attached to the medical device.
