20080300454 | TREATMENT TOOL - A treatment tool used with an endoscope includes a flexible sheath having an internal insertion through hole which extends in the axial direction of the sheath; one or more holes that are placed in a distal end portion of the sheath, and that penetrate a wall portion of the sheath so as to allow the insertion through hole to communicate with the outside of the sheath; a wire that passes from the insertion through hole in the sheath through the hole portion so that a portion thereof is exposed to the outside of the sheath; and a wire restricting portion that is provided in the vicinity of at least one hole portion from among the one or more hole portions, and that prevents the wire which is passing through the hole portion and extending to the outside of the sheath from shifting from the radial direction of the sheath. | 12-04-2008 |
20080300594 | INCISION TOOL - An incision tool includes a sheath; a plurality of wires that are inserted through an internal space of the sheath, and that, as a result of a portion thereof being inserted through both first wire insertion through holes that are provided in a distal end portion of the sheath and second wire insertion through holes that are provided on the sheath distal end side of the first wire insertion through holes, are exposed on the outside of the sheath between the first wire insertion through holes and the second wire insertion through holes, and that receive high-frequency current; and an operating unit that is connected to a base end side of the wires and that adjusts the length of the exposed portions of the wires which are exposed on the outside of the sheath by moving forwards or backwards relatively to the sheath in the longitudinal direction of the wires. | 12-04-2008 |
20080319259 | MEDICAL TUBE, MEDICAL INSTRUMENT, STENT SET AND ENDOSCOPE DEVICE - A first aspect of the present invention relates to a medical tube including: a tube main body; a sealed space which is formed in the tube main body and is sealed on both ends; and a variable hardness resin which fills the sealed space and the hardness of which can be changed by supplying energy thereto. A second aspect of the present invention relates to a medical tube including: a tube main body having at least one lumen; a variable hardness resin which fills the inside of the lumen and the hardness of which can be changed by supplying energy thereto; and an outflow preventing mechanism which prevents the filling variable hardness resin from flowing out from the lumen. | 12-25-2008 |
20090005855 | ENDOSCOPE TREATMENT TOOL - A stent system | 01-01-2009 |
20090099414 | METHOD OF PERFORMING DIAGNOSIS OR TREATMENT ERENDOSCOPICALLY AND MEDICAL TREATMENT DEVICE - A method of performing diagnosis or treatment perendoscopically in which a guide catheter is inserted inside a body, and the guide catheter is made to protrude beyond a distal end portion of the endoscope; and in which a first diagnosis or treatment is performed by inserting a medical treatment device that performs the diagnosis or treatment of the body inside the guide catheter, and causing this medical treatment device to protrude by a first predetermined distance from the guide catheter; and in which the medical treatment device is extracted from the guide catheter; and in which a second diagnosis or treatment is performed by inserting a medical treatment device into the guide catheter, and causing the medical treatment device to protrude by a second distance which is adjusted in accordance with the first predetermined distance. | 04-16-2009 |
20090125037 | LIGATION TOOL FOR ENDOSCOPE AND ENDOSCOPIC LIGATION SYSTEM - A ligation tool for endoscope includes an overtube having an insertion lumen | 05-14-2009 |
20090137867 | ENDOSCOPE TREATMENT SYSTEM - An endoscope treatment system includes: an endoscope; and a treatment tool that has a sheath that is inserted in a channel of an insertion portion of the endoscope, in which projection portions that project outward from the sheath in the radial direction are provided, and engagement portions that engage the projection portions are provided near the channel of the endoscope. | 05-28-2009 |
20090177030 | ENDOSCOPIC INCISION SYSTEM - An endoscopic incision system includes: an endoscope; a cylindrical member for covering at least a distal end of an insertion section of the endoscope; and at least an incision section for incising a living tissue, the incision section being provided to a distal end of the cylindrical member and being capable of being exposed from the distal end of the cylindrical member outwardly. In this configuration, the radially expanding incision section will not be twisted or bent, and the incision section prevented from inadvertent fall-off can maintain the desirable shape when it is operated and rotated. | 07-09-2009 |
