Abstract: A catheter includes a shaft part having a first shaft and a second shaft. The first shaft is a cylindrical member having a guide wire lumen into which a guide wire is inserted. The second shaft is a cylindrical member having an imaging lumen into which an imaging device for acquiring an image of an interior of a living body lumen is inserted, and is disposed alongside the first shaft. In a first region from a first position at a distal end portion of the shaft part to a second position further on a proximal end side than the first position, the second shaft is not joined to the first shaft. In a second region that is continuous with the first region and that is further on the proximal end side than the first region, the second shaft is joined to the first shaft.

Abstract: Connection transmitter for connecting a guidewire to a connector assembly (14), comprising: —a casing (16) surrounding at least partially the connector assembly, —a longitudinal connecting element (18) extending inside the casing along a longitudinal axis (X). The connecting element is translatable along a transversal axis, and receives the guidewire. The connector assembly comprises at least one connection blade extending along the transversal axis, and the connecting element comprises at least one transversal cavity (26) for receiving the guidewire, and cooperates with the connection blade. The connection transmitter presents: —a non-connecting configuration, in which the transversal cavity (26) and the connection blade are transversely disengaged, —a connecting configuration, in which the transversal cavity (26) and the connection blade are transversely cooperating by engagement. The connecting configuration enables to connect the guidewire with the at least connection blade.

Abstract: A medical device may include a handle and a flexible sheath extending from the handle. The sheath may include a first chamber configured to receive a first agent and a second chamber configured to receive a second agent. Each of the first chamber and the second chamber may be disposed in a distal portion of the sheath.
The sheath may also include a first piston received within the first chamber and a second piston received within the second chamber and at least one actuation element configured to transmit a force from the handle to each of the first piston and the second piston. In a first configuration, the first agent may be maintained within the first chamber and the second agent is maintained within the second chamber. In a second configuration, the first agent may be released from the first chamber to mix with the second agent.

Abstract: A guide wire for guiding a dilator to be inserted into a living body includes: a flexible elongated shaft portion; a puncture portion at a distal end portion of the shaft portion to form a hole in biological tissue; and an elastically deformable cover portion covering the puncture portion. The cover portion includes a sparse pitch portion that has a wire member wound in a spiral shape and axially contractible, and a distal end cover located on a distal end side of the sparse pitch portion and covering at least a part of the puncture portion. The puncture portion includes a first contact portion. The distal end cover includes a second contact portion configured to contact the first contact portion from a proximal end side, so that relative axial movement of the first and second contact portions is restricted by the first contact portion contacting the second contact portion.
