Abstract

An instrument for deploying an implantable medical device into a body lumen is disclosed. The instrument comprises a base member having a base handle and a deployment extension, a first tubular member having a first tubular body and a first handle, and a second tubular member having a second tubular body and a second handle. The first tubular member fits over the deployment extension and is longitudinally slidable over the deployment extension, and the second tubular member fits over the first tubular member and is longitudinally slidable over the first tubular member. The distal ends of the deployment extension, the first tubular body, and the second tubular body are adapted to hold and deploy the implantable medical device.

Claims

1. An instrument for deploying an implantable medical device in a body lumen, the device comprising:

a base member comprising

a base handle; and

a deployment extension having a distal end and a proximate end, the proximate end is connected to the base handle;

a first tubular member that fits over the deployment extension and is longitudinally slidable over the deployment extension, the first tubular member comprising;

a first tubular body with a distal end and a proximal end; and

a first handle for controlling movement of the first tubular member; and

;

a second tubular member that fits over the first tubular member and is longitudinally slidable over the first tubular member, the second tubular member comprising;

a second tubular body with a distal end and a proximal end; and

a second handle for controlling movement of the second tubular member,

wherein the first handle is located between the base handle and the second handle and wherein the distal ends of the deployment extension, the first tubular body, and the second tubular body are adapted to deploy an implantable medical device.

2. The instrument of claim 1, wherein the base member further comprises a guiding extension, the guiding extension is connected to the base handle and extends in a direction parallel to the deployment extension.

3. The instrument of claim 1, wherein the base member further comprises a coupling device for a viewing device or a guide wire.

4. The instrument of claim 3, wherein the viewing device is an endoscope.

5. The instrument of claim 1, wherein the deployment extension comprises means at the distal end for attachment of a catheter.

6. The instrument of claim 1, wherein the body lumen is a blood vessel.

7. The instrument of claim 1, wherein the body lumen is a bile duct.

8. The instrument of claim 1, wherein the first handle of the first tubular member comprises a stabilizing ring that fits over the guiding extension of the base member and is longitudinally slidable over the guiding extension.

9. The instrument of claim 1, wherein the first tubular member comprises interlocking means for attachment to the second tubular member.

10. The instrument of claim 9, wherein the interlocking means includes a locking tab on the first tubular body and a matching locking hole on the second tubular body.

11. The instrument of claim 1, wherein the base handle, the first handle and the second handle are beveled handles.

12. The instrument of claim 1, wherein the first tubular member has contoured sides to facilitate single-finger control of the first tubular member.

13. The instrument of claim 1, wherein the deployment extension of the base member further comprises a compression stopper to prevent the instrument from being over deployed.

14. The instrument of claim 1, wherein the implantable medical device is a stent.

15. A method for delivering an implantable medical device to a body lumen using the instrument of claim 1.

16. The method of claim 15 comprising the steps of:

attaching the first tubular member to the base member by sliding the first tubular body over the implantable medical device and the deployment extension;

attaching the second tubular member to the base member by sliding the second tubular body over the first tubular body;

attaching a proximate end of a catheter to the distal end of the second tubular body, wherein an implantable medical device is attached to a distal end of the catheter;

advancing the distal end of the catheter into the body lumen; and

retracting the first tubular member and the second tubular member towards the base member to deploy the implantable medical device in the body lumen.

17. The method of claim 16, wherein the retracting step includes:

(1) retracting the second tubular member towards the proximate end of the first tubular member; and

(2) retracting the first tubular member towards the proximate end of the base member.

18. The method of claim 16, wherein the retracting step includes:

(1) retracting the first tubular member towards the proximate end of the base member, and

(2) retracting the second tubular member towards the proximate end of the first tubular member.

19. The method of claim 16, further comprising attaching an endoscope to the base member.

20. The method of claim 16, wherein said implantable medical device is attached to a distal end of said catheter.

21. The method of claim 16, wherein the implantable medical device is a stent.

22. The method of claim 16, wherein the body lumen is a blood vessel or a bile duct.
