<P>PROBLEM TO BE SOLVED: To provide an anchor device and an intraluminal anchoring system which are capable of easily, quickly, and surely anchoring an intraluminal device to a living body tissue in the living body lumen. <P>SOLUTION: A anchor device 2 has a supporting member 3 and a plurality of pins 5 (three pins in the constitution shown in the figure) arranged in the supporting member 3. The supporting member 3 is constituted by crossing line-shape bodies 31 into a net shape and can assume folded and expanded states and is configured such that the entire shape is a substantially cylindrical shape in an expanded state. Further, the line-shape bodies 31 are made of a biodegradable material. Furthermore, each pin 5 is juxtaposed along the circumferential direction of the supporting member 3 in a state in which the supporting member 3 becomes a substantially cylindrical shape. The pin 5 has a puncturing portion 52 and a backbone portion 53 and the puncturing portion 52 is extendedly protruded from a proximal end portion 532 of the backbone portion 53. <P>COPYRIGHT: (C)2010,JPO&INPIT |
