Claim:
An artificial blood stent insertion device for use in vessel surgery which comprises: a moving tube and an outer tube, said moving tube being slidably disposed to move back and forth within the outer tube, said moving tube being provided with a grip member positioned at one end thereof, a guide passing tube slidably and axially disposed within the outer tube, and a cylindrical, artificial blood stent disposed between the moving tube and the outer tube, said blood stent being operatively compressed by a fixing wire to the guide passing tube at a front end portion, a middle portion and a rear end portion of said blood stent such that the compression at the front end and rear end portions is greater than the compression at the middle portion, said fixing wire being provided with loops disposed at the sides thereof, and a core member passing through the loops of the fixing wires and through the moving tube and terminating at the grip member, wherein the artificial blood stent is positioned within a blood vessel by pushing the moving tube into the outer tube, displacing the artificial blood stent from the outer tube and disengaging the core member from the loops of the fixing wires causing the artificial blood stent to expand to its cylindrical shape.
