Abstract
A system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region, which is capable of accurately treating an affected area in a blood vessel while preventing adverse effects for healthy tissue. The system includes a catheter which is positionable in a blood vessel at the interventional procedure site. The system further includes an interventional instrument such as a self-expandable stent which may be deployed in the blood vessel at the interventional procedure site. The system also includes an extendable member, adapted to be about the interventional instrument for delivery of the interventional instrument to the interventional procedure site, and to be retractable from extending about the interventional instrument for enabling the interventional instrument to expand at the interventional procedure site. The system further includes movement preventing elements, for preventing axial movement of the interventional instrument in a support region of a catheter elongated shaft, during retraction of the extendable member from extending about the interventional instrument, for enabling accurate deployment of the interventional instrumen…
