Abstract
A blood vessel expanding pipe with cut seams is a round pipe made of high-molecular materials or soft metal. The round pipe can be folded in a reeling way or expanded. With the cut seams on the pipe wall, the round pipe can be also bent. Before an operation, the round pipe is reeled and folded in a way to be parallel to the axial direction and forms a reeled column. The reeled column and a guide wire are inserted into an ingress pipe with an inner diameter slightly larger than the outer diameter of an envelope of the reeled column. The reeled column which is guided by the guide wire is conveyed to a target blood vessel and pushed out of the ingress pipe. An expanding device is guided into the reeled column through the guide wire. The reeled column is expanded by the expanding device. Then a round-pipe-shaped expanding pipe is formed to improve the blood circulation condition in a narrow part of the blood vessel.
