20140350330 | EXPANSION INSTRUMENT - An expansion instrument includes an elongated vaginal-insertion member insertable into the vaginal lumen which is adjacent the urethral lumen with biological tissue interposed between the two, an elongated urethral-insertion member insertable into the urethral lumen, an interlock device interlocking the vaginal-insertion member and the urethral-insertion member to allow the insertion members to be brought closer together and brought farther apart, and a vaginal-side restriction that restricts the positional relationship, with respect to the biological tissue, of the vaginal-insertion member after being inserted into the vaginal lumen. The vaginal-side restriction is on the vaginal-insertion member and has a configuration such that in a state where the vaginal-insertion member is in the vaginal lumen, the urethral-insertion member is in the urethral lumen, and the positional relationship has been restricted by the vaginal-side restriction, moving the vaginal-insertion member farther away from the urethral-insertion member widens the biological tissue in the moving away direction. | 11-27-2014 |
20150018606 | CATHETER ASSEMBLY - The catheter assembly includes a catheter having a catheter body, and a curved stylet that is constituted of a linear body of higher rigidity than the catheter body and is inserted into the catheter, the catheter assembly being assembled by inserting the curved stylet into the catheter. The curved stylet has a curved section, a part of which is curved. A deformation section that has been deformed in a curved manner along the curved shape of the curved section is formed on the catheter body at a portion where the curved section is located in the assembled state. The catheter assembly is so configured that, when the catheter is inserted into the urethral lumen in the assembled state, the deformation section curves a portion of the urethral lumen that faces the deformation section. | 01-15-2015 |
20150073206 | PUNCTURE DEVICE AND PUNCTURE APPARATUS - A puncture device, a puncture apparatus, and a method are disclosed, the puncture apparatus including a puncture device for puncturing a biological tissue, a urethral-insertion member, a vaginal insertion member, and a supporting member which supports the urethral-insertion member, vaginal insertion member and a puncture member of the puncture device. The puncture device includes a puncture needle for puncturing a biological tissue, a shaft portion and a connection portion for connecting the puncture needle and the shaft portion to each other, and an implant assembly positioned at a distal end of the puncture needle and having a needle tip portion for puncturing a biological tissue and a biological tissue supporting implant. The puncture needle has a form of a pipe and has a tubular portion. The biological tissue supporting implant is accommodated in the hollow portion. | 03-12-2015 |
20150073465 | PUNCTURE APPARATUS - A puncture apparatus is disclosed, which includes a first apparatus, a second apparatus, and an apparatus main body. The first apparatus includes a puncture needle assembly and a support member that supports the puncture needle assembly. The puncture needle assembly includes an outer tube curved into a circular arc shape and an inside structural body composed of a needle body and an implant. Two ultrasonic sensors are placed at the distal portion of the outer tube. The second apparatus can include a vaginal-insertion portion, a urethral-insertion member having a urethral-insertion portion, and an interlock portion that interlocks the vaginal-insertion portion with the urethral-insertion member. Reflective portions that reflect ultrasound are provided on the urethral-insertion portion and the vaginal-insertion portion, respectively. | 03-12-2015 |
20150080644 | IMPLANT AND METHOD OF PLACING IMPLANT INDWELLING - An implant and a method of placing an implant indwelling are disclosed. The implant, to be placed indwelling in a living body, is inserted into a medical tube prior to being placed indwelling. The implant can include an implant main body which is flexible, is elongated, and is shorter than a length of the medical tube; a guide portion which, at the time of insertion of the implant main body into the medical tube, is inserted into the medical tube prior to the implant main body and guides the implant main body; and an interlock portion which interlock the implant main body and the guide portion to each other, the interlock being released after the implant main body is inserted into the medical tube. | 03-19-2015 |
20150080930 | PUNCTURE APPARATUS AND PUNCTURING METHOD - A puncture apparatus and a puncturing method are disclosed by which a biological tissue is punctured. The puncture apparatus can include an elongated curveable puncture needle which punctures a biological tissue, and a curvature-changing unit which changes curvature of the puncture needle in a process of puncturing the biological tissue by the puncture needle. The puncturing method can include puncturing in such a manner that curvature of the puncture hole varies along a longitudinal direction of the puncture hole, in a process of puncturing the biological tissue. | 03-19-2015 |
20150080932 | TISSUE SEPARATION DEVICE - A tissue separation device includes: a sheath; a tube having a deformation part; a restriction member; and an inner structure. The tissue separation device is used in an assembled state where the tube is movably inserted in the sheath, the restriction member is inserted in the tube, and the inner structure is movably inserted in the restriction member. The inner structure includes: wires and which are expandable and contractible; an operation unit which operates expansion of the wires; a tubular body; and a traction shaft. The wires are expanded by being curved so as to protrude in opposite directions. When dissecting a biological tissue, the wires in an expanded state are moved within the tube in relation to the tube, without moving the tube relative to the living body. | 03-19-2015 |
20150087895 | METHOD OF PLACING IMPLANT INDWELLING - A method of placing an implant indwelling in a living body is disclosed. The method can include forming an insertion hole in the living body, the insertion hole extending from a living body surface and passing an obturator foramen on one side and an obturator foramen on the other side, the insertion hole having its end portion on the one side opened in the living body surface and its end portion on the other side closed in relation to the living body surface; inserting a medical tube that permits the implant to be inserted into the medical tube, prior to insertion of the implant; inserting the implant into the medical tube inserted in the insertion hole; and pulling the medical tube out of the insertion hole so that the implant is placed indwelling in the living body. | 03-26-2015 |
