摘要： The present invention provides a PFO closing device for bringing septum primum and septum secundum into contact and joint with each other. The device includes clamping means and energy supplying means. The clamping means includes a needle part for puncturing the septum primum, and a clamping member for cooperating with the needle part in clamping therebetween the tissues having the septum primum and the septum secundum. The energy supplying means supplies energy for joining the tissues clamped by the needle part and the clamping member. The clamping means is mounted in a catheter so as to be protrudable from and retractable into the catheter.

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 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： There are provided a medical device and a treatment method by which it is possible to appropriately maintain a range in which it is possible to crush an object formed in a body lumen. A medical device (10) for crushing an object in a body lumen by being inserted into the corresponding body lumen, the medical device including: an elongated shaft portion (20) that is to be rotatably driven; a crushing unit (60) that is provided with bendable wire rods and is rotatable together with the shaft portion (20); and a sliding unit (50) that is fixed to each of end portions of the wire rods on at least one of a distal side of and a proximal side of the wire rods and is interlocked with the shaft portion (20) so as to be slidable in an axial direction of the shaft portion (20). The shaft portion (20) is provided with contact portions (42) that are to come into contact with the sliding unit (50) during rotation and are to limit relative rotation of the shaft portion (20) and the sliding unit (50). After the sliding unit (50) is attached to the contact portions (42), the sliding unit (50) rotates in the same direction as the shaft portion (20) along with the rotation of the shaft portion (20) .
