INTRAVASCULAR HEMOSTASIS-TYPE CATHETER

摘要

PROBLEM TO BE SOLVED: To provide a unit which is usable for blood vessels of various sizes and can restrain hemorrhage in a blood vessel without blocking the blood flow toward the peripheral side. SOLUTION: An intravascular hemostasis-type catheter 10 contains: an elastically deformable portion 11 provided with a plurality of wire members 33 that are disposed apart from each other in the circumferential direction, maintaining an inflated shape in a basket shape, in which the wire members 33 are apart from each other and the outer diameter of a central portion 34 in a longitudinal direction 101 is enlarged, and elastically deforming into a deflated shape in which the wire members 33 come close to each other and the outer diameter of the central portion 34 is reduced; a shaft 12 provided with the elastically deformable portion 11 at the top end side thereof; a catheter body 13 having a lumen 20 through which the elastically deformable portion 11 in the deflated shape and the shaft 12 can pass; and a hemostatic film 15 which is stretched only at the central portion 34 of the elastically deformable portion 11 in the circumferential direction relative to the wire members 33 in the inflated shape and which has flexibility with which the hemostatic film 15 can follow the change in the shape of the elastically deformable portion 11.
