SELF-EXPANDABLE STENT

摘要

A self-expandable stent includes a plurality of first wires and a plurality of second wires interwoven together. A first anchor member is attached to a distal end of one of the plurality of first wires. The distal end of the first anchor member is fixed to the distal end of the one of the plurality of first wires, but the proximal end is a free end and is not fixed to any of the plurality of first wires or to any of the plurality of second wires. Consequently, the self-expandable stent is capable of contacting a blood vessel wall or digestive organ wall at the optimal position when the self-expandable stent is expanded at the target site. A gap is not easily formed between the anchor member and the blood vessel wall or digestive organ wall, and thus the self-expandable stent is not easily dislocated from the target site.
