Device for deploying an implantable medical device
View Patent ↗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.
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;

14. The device according to claim 13 , wherein the variable tensile force is a decreasing tensile force.
15. 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 retraction of the deployment line from the remotely deployable implantable device;
wherein said control component comprises a plurality of variably spaced teeth elements, whereby actuation of the control component results in emission of an audible sound as said deployment line is retracted a predetermined interval.
16. The device of claim 15 , wherein the actuation mechanism comprises a cam.
17. The device of claim 15 , wherein the remotely deployable implantable device comprises a self-expanding device.
18. The device of claim 15 , wherein the remotely deployable implantable device comprises a stent.
19. The device of claim 15 , wherein the remotely deployable implantable device comprises an implantable filter.
20. A system, comprising:
a catheter having a proximal and distal end;
a remotely deployable member releasably attached to the distal end of said catheter;
