LIVING BODY LUMEN TREATMENT SYSTEM AND STENT

摘要

A living body lumen treatment system includes a sheath that internally has a receiving lumen, and a stent that is received in a contracted state by the receiving lumen and that expands by being exposed from the sheath. A first region to which a drug is applied and a second region to which the drug is not applied are set to be located on an outer surface of the stent. The sheath has a protrusion portion protruding beyond an inner wall. In the stent, the second region is brought into contact with and supported by the protrusion portion so as not to bring the first region into contact with the inner wall.

1. A living body lumen treatment system comprising:
a tubular body that can be delivered into a living body lumen, and that internally has a lumen extending in an axial direction; and an expandable body that is received in a contracted state by the lumen, and that expands by being exposed from the tubular body so as to come into contact with an inner surface of the living body lumen, wherein a first region to which a drug is applied and a second region to which an application agent having an application form different from the drug is applied or to which the drug is not applied are set to be located on an outer surface of the expandable body, the tubular body has a protrusion portion protruding inward beyond an inner wall which configures the lumen, and the expandable body is received by the lumen in such a way that the second region is brought into contact with and supported by the protrusion portion so as not to bring the first region into contact with the inner wall.
