Abstract

A device for guiding a branched artificial blood vessel 1 having a tubular main body 5 with collapsible/restorable elasticity and a branch portion 6 with collapsible/restorable elasticity which branches from a part of the main body 5 with its internal space communicating with the main body 5, which artificial blood vessel 1 has been transferred as collapsed in a main blood vessel 2 to a branched part 4 branching a branch blood vessel 3 from the main blood vessel 2, the device being utilized in inserting the branch portion 6 of the artificial blood vessel 1 into the branch blood vessel 3, the device comprising an operating rod 9a inserted into the main body 5 from a trailing open end thereof and operable for rotation by hand, a guiding rod 9b continuously connected to the operating rod 9a so as to be capable of turning around with rotation of the operating rod 9a and having a leading end extending to an open end of the branch portion, and mooring means 9c for releasably mooring the branch portion by a portion adjacent the open end thereof to the guiding rod 9b, wherein when the main body is moved backward with the guiding rod 9b made to assume a predetermined position by turning, the branch portion 6 accompanying the guiding rod 9b is capable of advancing into the branch blood vessel 3 together with the guiding rod 9b.
