Abstract

Device useful for implanting an implantable device within the vasculature of a patient. The device includes a deployment line, a control component for actuating the deployment line, and an actuation mechanism for translating constant-rate actuation of the control component into variable rate retraction of the deployment line from a remotely deployable implantable device. Suitable implantable devices include, for example, stents and stent grafts.

Claims

1. A device for retracting a deployment line of a remotely deployable implantable device comprising:

a deployment line adapted to effect deployment of the remotely deployable implantable device;

a control component for actuating the deployment line; and

an actuation mechanism for translating constant-rate actuation of the control component into variable rate retration of the deployment line from the remotely deployable implantable device.

2. The device of claim 1, wherein the actuation mechanism comprises a cam.

3. The device of claim 1, wherein the actuation mechanism comprises a variable pitch lead screw.

4. The device of claim 1, wherein the deployment line retracts at a slow rate during initial deployment and retracts at an increased rate following initial deployment.

5. The device of claim 4, wherein the deployment line retracts at an increasing rate following initial deployment.

6. The device of claim 1, wherein the control component comprises a thumb operable wheel.

7. The device of claim 1, wherein the remotely deployable implantable device comprises a self-expanding device.

8. The device of claim 1, wherein the remotely deployable implantable device comprises a stent.

9. The device of claim 1, wherein the remotely deployable implantable device comprises an implantable filter.

10. A device for retracting a deployment line of a remotely deployable implantable device comprising:

a deployment line adapted to effect deployment of the remotely deployable implantable device; and

a rotary control component for actuating the deployment line wherein rotation of the rotary control component at a constant angular velocity results in variable rate retraction of the deployment line.

11. The device according to claim 10, wherein the variable rate retraction is effected by a rotary cam.

12. The device according to claim 11, wherein the variable rate retraction is an increasing rate.

13. The device according to claim 10, wherein the variable rate retraction is an increasing rate.

14. A device for retracting a deployment line of a remotely deployable implantable device comprising:

a deployment line adapted to effect deployment of the remotely deployable implantable device; and

a rotary control component for actuating the deployment line wherein rotation of the rotary control component at a constant angular velocity results in variable tensile force applied to the deployment line.

15. The device according to claim 14, wherein the variable tensile force is a decreasing tensile force.
