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 (14)

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 and having a proximal end and a distal end;

a control component for actuating the deployment line;

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

a housing component having a proximal end and a distal end;

wherein said control component comprises a bore and a pin element inserted into said bore and in contact with and attached to the proximal end of said deployment line.

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 remotely deployable implantable device comprises a self-expanding device.

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

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

7. The device of claim 1 , wherein the control component is a rotary control component configured to rotate about an axis of rotation, and wherein the bore and the pin element are spaced apart from the axis of rotation such that the proximal end of the deployment line is connected to the control component outside the axis of rotation.

8. The device of claim 1 , wherein the pin element is configured to facilitate rotation of the pin within the bore to take up slack in the deployment line during assembly of the device without movement of the actuation mechanism.

9. The device of claim 8 , wherein the pin element is configured to facilitate the rotation of the pin while partially inserted within the bore, wherein the pin element includes a head with an irregular surface about a perimeter of the head, and wherein the bore of the control component includes a mating irregular surface to prevent, once the pin is fully inserted within the bore during assembly of the device, the pin from rotating within the bore.
