    摘要： Methods and apparatus for making an anastomotic connection between a first conduit and a second conduit. A connector structure having a first end portion and a second end portion is positioned about a balloon catheter, which when pressurized, expands to a significant extent at the distal end thereof. The balloon enlarges the connector structure when positioned at the distal end portion of the balloon to create the anastomosis, and at the same time reduces the axial length of the connector, thereby compressing the first conduit to the second conduit, creating a hemodynamic seal and a firm attachment of the two conduits. After enlargement, the connector structure remains in place and adds structure to the anastomosis. During introduction, the second end portion of the connector is covered by a nosecone assembly to prevent trauma to the second conduit while the apparatus is being introduced. The nosecone assembly has a flexible structure which may change configuration to expose the second set of members after insertion into the second conduit and to allow removal of the nosecone after deployment.

    摘要： An insertion assisting device includes a rotary body formed in a toroidal shape, and a support and drive unit that rotatably supports and rotates the rotary body. The support and drive unit has two supports, a first support and a second support. The first support is formed in a substantially cylindrical shape, and rotatably supports the rotary body. The second support is formed in a substantially triangular tubular shape, is arranged inside the first support, and supports driving gears that transmit a driving force to the rotary body. The second support is shorter than the first support, and is arranged so that front and rear end portions thereof are located inside front and rear end portions of the first support.

    摘要： An insertion and extraction assisting device of an endoscope has a promotion unit attached on the front end side of the endoscope and a transmission section whose one end is connected to a promotion unit, and the other end is drawn along the endoscope, and an outside unit. The other end of the transmission section is connected to the outside unit, and rotational force or a turn signal from the outside unit is transmitted to the promotion unit, so that driving force is generated by the promotion unit. When the other end of the transmission section is connected to, the outside unit reads an ID code expressing a kind of the promotion unit and controls the rotational force or the turn signal to send to the promotion unit.

    摘要： A propelling device includes a rotary body, an external cylinder for supporting a rotary body in a circulating manner, a first drive mechanism, and a second drive mechanism. The first drive mechanism has a torque wire and a pinion gear that are provided in a distal portion of the insertion part. The second drive mechanism has an internal cylinder mounted on the distal portion of the insertion part, a transmission gear rotatably supported outside the internal cylinder, and a housing cylinder provided outside the transmission gear. The transmission gear has a worm gear on the outer peripheral surface thereof, and a gear tooth portion that meshes with a pinion gear on an inner peripheral surface thereof. The housing cylinder has drive gears that mesh with the worm gear. Although the second mechanism is replaced at each inspection, the first mechanism provided at the insertion part is repeatedly used.
