Abstract: A stent graft transport device includes a mounted state keeping wire that keeps a mounted state of a stent graft on a transport tube or a contracted state keeping wire that keeps a contracted state of the stent graft. The transport tube can be separated from the stent graft by pulling an operation end part of the mounted state keeping wire, and the stent graft can be in an expanded state by pulling an operation end part of the contracted state keeping wire. Furthermore, the operation end part of each of the wires is housed inside the transport tube. In order to draw the operation end part, a wire pulling-out string is provided, one end part of which is mounted on the mounted state keeping wire and the other end part of which is pulled out from a window arranged on a side peripheral surface of the transport tube.
Abstract: This invention provides a stent graft transport device that can perform not only automatic rotational angle adjustment by means of self-alignment, but also smooth and easy transportation. The stent graft transport device transports a stent graft to a lesion part along a guide wire that is inserted into the inside of a blood vessel beforehand. The stent graft transport device includes a posture control member that is provided with a through bore through which the guide wire slidably passes in a curved state in one direction. The stent graft transport device is also characterized in that the posture control member is shorter than the stent graft and is mounted on a distal end part of the stent graft.
Abstract: This invention provides a stent-graft that has both shape-maintainability and flexibility, and when implanted in a living body, the stent-graft performs its intended functions for a considerably long period of time relative to conventional stent-grafts, without causing conflict. The stent-graft comprises a stent comprising multiple elastic rings and a graft. An auxiliary elastic wire whose rigidity is lower than that of the stent is arranged at the end-part of the graft, and the auxiliary elastic wire is connected to the multiple elastic rings at the opening part.
Abstract: To provide a medical tool that dramatically simplifies operations and has a small number of parts. For this purpose, the medical tool includes: an outer tube; a core that is inserted into the outer tube so as to be movable forward and backward; a medical tool main body that is attached to the core; and a containing member that is attached to the fore end of the outer tube, and is configured such that when by moving the outer tube forward relatively to the core, the containing member is made to approach the medical tool main body released out of the containing member, the containing member makes driving force for operating the medical tool main body act on the medical tool main body.
Abstract: A therapeutic or diagnostic instrument includes first and second shaped wire members and that can be simultaneously inserted into a catheter tube and has predetermined bending elasticity, in which the first and second shaped wire members and are adapted to respectively have first and second curving parts that curve in a natural state, and when inserted into the catheter tube, curve the catheter tube at two desired positions correspondingly with the first and second curving parts.
