摘要:
What is disclosed is a medical device comprising a compressed, cylindrical or oblong, thin-walled, expandable metal structure (a "blockstent") and a flexible, elongated device (a "delivery catheter") to position the compressed blockstent into the lumen of a blood vessel segment to be treated, and methods of use for occlusion of treated blood vessel segments. A blockstent can be made with ductile metals such as gold, platinum, or silver such that the blockstent will conform to the shape of the lumen of the treated blood vessel segment during expansion and allow for the shape of the blockstent to be permanently changed by the application of an external force. The surface of the blockstent can be configured to promote local thrombus on the external surface of the blockstent and to promote the growth of tissue into the wall of the blockstent in order to occlude the treated blood vessel and fix the blockstent in place. The wall of the blockstent can also be configured to release drugs or pharmacologically active molecules such as those that promote thrombosis, cell proliferation, extracellular matrix deposititon to promote this thrombus formation and tissue growth.
