20130253531 | PUNCTURE APPARATUS - A puncture apparatus includes a puncture needle for puncturing living body tissue, an axial portion, a puncture member including an interlock portion interlocking the puncture needle and the axial portion, an elongated urethral-insertion member insertable into the urethra, an elongated vaginal-insertion member insertable into the vagina; and a supporting member supporting the puncture member, the urethral-insertion member and the vaginal-insertion member. The distal end of the puncture needle includes a sharp needle tip, and the needle is bent in an arc shape centered on the axial portion. The axial portion is freely rotatable on the supporting member, and the supporting member restricts the positional relation between the puncture member and the urethral-insertion member such that when the puncture member rotates and punctures the living body tissue, the needle tip passes a far-position side from the center of the puncture needle compared with the urethral-insertion member or an extended line of such member. | 09-26-2013 |

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 |

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 |
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 |
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 |
20150133789 | PUNCTURE APPARATUS - A puncture apparatus is disclosed, which can include an elongated insertion portion configured to be inserted into a living body lumen, a puncture needle configured to puncture a living body tissue near the insertion portion from a part different from the living body lumen, with the insertion portion inserted in the living body lumen, a puncture needle guide portion, which movably supports the puncture needle and which determines a puncture path for a needle tip of the puncture needle when the puncture needle punctures the living body tissue, an ultrasonic transmission-reception section in the insertion portion or the puncture needle guide portion, for transmission and reception of an ultrasonic wave, and an image data production section for producing image data for displaying on a display section an image including the living body lumen and a predicted path of the puncture path, based on information acquired by the ultrasonic transmission-reception section. | 05-14-2015 |

The main body has a flat shape including a minor axis and a major axis as a cross-sectional shape at the central portion in the longitudinal direction thereof. The angle formed between the minor axis and a plane containing both a center point of the circular arc in the central portion and a center point of the cross-sectional shape with respect to the longitudinal direction of the main body is an acute angle. The angle is preferably 20° to 60°. The medical tube thus configured is for use in treatment of a disorder in a pelvic organ, by indwelling an implant between a urethral lumen and a vaginal cavity. | 01-28-2016 |
