Abstract
An improved apparatus for delivering and deployment of an expandable stent with a protection sheath within a blood vessel is provided. The system comprises a fluid pressure device which is coupled with a retraction device for the protection sheath such that after retraction of the protection sheath the stent is automatically deployed by the fluid pressure device. The advantage of the invention is an easy and simple operation of the apparatus.
Claims11
Apparatus for delivery and deployment of a stent within a vessel, the stent being expandable from a delivery diameter to a deployed diameter, the apparatus comprising:
- a catheter having a proximal end and a distal end;
- an expandable means mounted at the distal end of the catheter and being expandable by means of a fluid pressure device, the expandable means configured to permit mounting of the stent thereon;
- a sheath configured to be advanced over the stent and being arranged for proximal retraction to expose the stent by means of a retraction device,
- wherein the fluid pressure device is further arranged to operate the retraction device so that the expandable means is expanded in response to the retraction of the sheath.
