摘要： [Problem] Provided are a medical device capable of preventing a maintenance treatment element imparting energy to biological tissue from being displaced from a treatment target site and a treatment method performed on a heart failure patient.
[Means for Resolution] A medical device 10 includes a shaft portion 150, an expandable and contractible expansion body 100 provided on a distal side of the shaft portion, and a maintenance treatment element 109 disposed in the expansion body and imparting energy to biological tissue. The expansion body includes a concave portion 115 recessed in a direction intersecting with an axial direction of the shaft portion. The maintenance treatment element is disposed in the concave portion.-

摘要： Provided are an energy generating device and a cauterization system which make it possible to uniformly cauterize bio tissues at a desired damage level and to reduce tissue damage or generation of distal embolization due to clot formation. This energy generating device (100) comprises a control unit (130) for controlling electric energy to be outputted to electrodes (22A-22D) for use in cauterizing bio tissues, wherein the control unit (130) has: an impedance calculation unit (132) which calculates impedance between an electrode and an counter electrode opposite thereto; and an output adjustment unit (131) which decreases electric power to the electrodes in the case when the impedance calculated by the impedance calculation unit (132) becomes equal to or greater than a predetermined threshold value.

摘要： Provided is a medical device which can suppress torsion of a wire in a circumferential direction in an expansion body formed using the wire.
Amedical device (10) includes an elongated shaft portion (20), and an expansion body (21) disposed in a distal portion of the shaft portion (20) , and configured to expand and contract in a radial direction. The expansion body (21) has wire portions (50) in which a distal portion and a proximal portion are linked with the shaft portion (20), and a holding portion (51) formed using at least one of the wire portions (50), and holding a biological tissue. At least one of a proximal side and a distal side of the holding portion (51) has an opening portion (57) formed using the wire portion (50) or formed using a plurality of the wire portions (50). When the expansion body (21) expands, the wire portion (50) forming the holding portion (51) faces the opening portion (57).-

摘要： Provided is a medical device which can suppress torsion of a wire in a circumferential direction in an expansion body formed using the wire.
Provided is a medical device (10) which enlarges a biological tissue. The medical device (10) includes an elongated shaft portion (20) and an expansion body (21) disposed in a distal portion of the shaft portion (20). The expansion body (21) has a wire portion (50) configured to expand and contract in a radial direction, and a torsion restriction portion (54) that restricts movement of the wire portion (50) in a circumferential direction of the expansion body (21).-

摘要： Provided are a medical device and a treatment method, in which energy is accurately applied to a target site by suppressing a positional displacement between an expansion body and a biological tissue.
There is provided a medical device (10) including an elongated shaft portion (20) and an expansion body (21) disposed in a distal portion of the shaft portion (20) and configured to expand and contract in a radial direction. The expansion body (21) has a hold portion (51) having a proximal side hold portion (51a) and a distal side hold portion (51b) which hold the biological tissue, and a movable portion (52) that opens and closes the holding portion (51) in a holding direction.-

摘要： A catheter includes: a catheter shaft; and a hub on a proximal side of the catheter shaft. The catheter shaft includes a shaft inner surface inclined portion at a proximal portion, the diameter of which increases proximally such that the shaft inner surface inclined portion forms an angle with the catheter central axis. The hub includes a first hub inner surface inclined portion continuous from the shaft inner surface inclined portion and inclined at the same inclination angle as the shaft inner surface inclined portion, and a second hub inner surface inclined portion proximal of the first hub inner surface inclined portion. The second hub inner surface inclined portion inclination angle differs from the first hub inner surface inclined portion inclination angle. The hub does not cover an inner peripheral surface of the catheter shaft in an interlock portion in which the catheter shaft and the hub are interlocked together.
