Abstract:
A device for guiding a branched appliance having a tubular main body with collapsible/restorable elasticity and a branch portion with collapsible/restorable elasticity which branches from a part of the main body with its internal space communicating with the main body, which appliance has been transferred in a collapsed state in a main blood vessel to a branched part branching a branch blood vessel from the main blood vessel, the device being utilized in inserting the branch portion of the appliance into the branch blood vessel, said device comprising:an operating rod insertable into the main body from a trailing open end thereof and operable for rotation by hand, a guiding rod continuously connected to the operating rod so as to be capable of turning around with rotation of the operating rod and having a leading end extendable to an open end of the branch portion, and mooring means for releasably mooring the branch portion by a portion adjacent the open end thereof to the guiding rod, wherein the device is usable such that when the main body is moved backward with the guiding rod made to assume a predetermined position by turning, the branch portion accompanying the guiding rod is capable of advancing into the branch blood vessel together with the guiding rod, and wherein the operating rod and the guiding rod are formed by turning up a flexible wire rod into a loop having a trailing side forming the operating rod and a leading side forming the guiding rod.
