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.

Claims

1. An insertion system for a medical device comprising:

a guide wire having an outer surface;

a 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 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.

2. The insertion system of claim 1 wherein said medical device and said insertion tool are both axially displaceable relative to said guide wire when said guide wire is received in said first and second bores.

3. The insertion system of claim 1 wherein said medical device further includes a filament connected thereto.

4. The insertion system of claim 3 further comprising a needle, said needle having an eyelet adapted for receipt of said filament therethrough.

5. An insertion system for a medical device comprising:

a guide wire having an outer surface;

a medical device having an inner surface defining a bore extending therethrough, said bore adapted to receive said guide wire therein, wherein at least a portion of said outer surface of said guide wire and at least portion of said inner surface of said medical device are in mating engagement when said guide wire is received in said bore; and

an insertion tool having an inner surface defining a longitudinal bore extending therethrough, said longitudinal bore adapted to receive said guide wire therein, wherein at least a portion of said inner surface of said longitudinal bore and at least of portion of said outer surface of said guide wire are in mating engagement when said guide wire is received in said longitudinal bore.

6. The insertion system of claim 5 wherein the mating engagement of said medical device and said insertion tool with said guide wire allows axial movement of said medical device and said insertion tool along said guide wire.

7. The insertion system of claim 5 further comprising a needle having an eyelet for receiving a filament, wherein said filament is attached to said medical device.

8. The insertion system of claim 5 wherein the cross-sections of said outer surface of said guide wire, at least a portion of said inner surface of said medical device, and at least a portion of said inner surface of said insertion tool are non-circular.
