BLOOD VESSEL-IMPLANTING APPARATUS, SYSTEM AND METHOD, AND APPARATUS USED TOGETHER THEREWITH

摘要

PURPOSE: To provide a device or system using a pusher rod assembly which can be constrained so that a relative large force can be applied thereto. CONSTITUTION: A vasepidermization device is composed of a flexible elongated pipe-like member 16 having a proximal end and a distal end, and a capsule and catheter 12 including a capsule 36 attached to the distal end. The capsule 36 is substantially cylindrical, and is formed of a spiral lap made of a metal ribbon 39. The lap 36 is formed into an integral capsule-like shape and is bendable. An epidermization piece formed of a pipe-like member having a proximal end and a distal end is laid in the capsule 36, and hooks are attached to the proximal end and the distal end, being directed outward toward the inner wall of the capsule 36. A push rod is located in the capsule catheter 12, being engaged with the epidermization piece. With this arrangement, it is possible to push out the epidermization piece from the capsule when relative motion occurs between the push rod and the capsule catheter.
