20100094284 | ORGAN INCISION METHOD - A method of making an incision in an organ includes piercing, by a puncture needle having a proximal end and a distal end, an abdominal wall and an organ that is to be incised, disposing, via the puncture needle, an electrode, to which a first end of a cable is electrically connected, inside the organ, and disposing a second end of the cable outside a body, performing insufflation using a conduit so as to form a space between the abdominal wall and the organ, pulling the cable farther from the second end so that the electrode is placed in contact with an incision position of the organ, and the incision position of the organ is pulled into the space, and supplying power to the cable so that an incision is made by the electrode at the incision position of the organ. | 04-15-2010 |
20100113873 | SUTURING DEVICE AND SUTURING SYSTEM - A suturing device for suturing tissues by using a suturing unit having an anchor mounted to an end portion of a suturing thread is provided, the suturing device including: a pair of first and second jaws which are opened or closed so as to grip the tissue; a hollow needle tube which receives the anchor in an inner cavity thereof; and a pusher which is inserted through the needle tube in a freely advancing and retracting manner and is capable of pushing the anchor received in the needle tube toward a distal end of the needle tube, in which the needle tube is disposed so as to intersect the first jaw and to allow the distal end thereof to face the second jaw, and in which, when the tissue is gripped by the first and second jaws, the needle tube is inserted into the tissue. | 05-06-2010 |
20100292532 | Endoscopic Vessel Dissector With Side Entry - A blunt dissector for endoscopic vein harvesting has a generally-cylindrical sheath for retaining an elongated endoscope. The sheath is elongated between a distal end and a proximal end. A transparent tip is disposed at the distal end of the sheath. A handle is disposed at the proximal end of the sheath. The sheath includes a selectably closable longitudinal slot having an opened configuration such that the endoscope can be inserted radially into the sheath. The longitudinal slot has a closed configuration that retains the endoscope within the sheath and presents a substantially smooth outer surface for use during dissection. | 11-18-2010 |
20110071354 | OVERTUBE AND MEDICAL PROCEDURE VIA NATURAL ORIFICE USING THE SAME - An overtube according to this invention includes: an insertion part, that is inserted into a subject and has a lumen, through which a device insertion part of a device for performing a medical procedure inside a body of the subject is removably inserted, the insertion part being inserted into the subject; and a tissue incising part that is disposed at a distal end side of the insertion part so as to cross the lumen and incises a tissue of the subject. | 03-24-2011 |
20120006337 | BIOLOGICAL TISSUE TRANSFER METHOD AND BIOLOGICAL TISSUE TREATMENT METHOD - The present application relates to a biological tissue transfer method for transferring a biological target tissue within the body, the method comprising: (a) attaching part of a first traction member to a first position which is different from a connecting position at which the target tissue is connected to other biological tissue; (b) attaching part of a second traction member to a second position which serves as the apex of a triangle formed together with the connecting position and the first position that surrounds the target site; (c) extending the first traction member in the direction from the connecting position to the first position, and extending the second traction member in the direction from the connecting position to the second position; and (d) transferring the target tissue within the body by applying traction on the first traction member and the second traction member respectively. | 01-12-2012 |
20120010460 | TISSUE DISPLACING METHOD - An organ displacing method implemented for performing a procedure in a patient's body cavity, the method includes a gravitational movement step in which the body position of the patient is changed, whereby surrounding organs adjacent to a hollow organ are moved in a primary direction by gravity; and a non-gravitational movement step in which, by using a medical instrument inserted into the hollow organ, the hollow organ is moved in a secondary direction where the hollow organ is separated from the surrounding organs. | 01-12-2012 |
20120232336 | ENDOSCOPE-HOLDING DEVICE AND ENDOSCOPIC SYSTEM - An endoscope holding device includes an insertion part that is long and holds the distal end part of an endoscope so as to freely protrude and retract; a distal end face that specifies a protruding direction of the endoscope, and is formed at the distal end of the insertion part, a displacement part which has a displacement face that is curved from the distal end toward a proximal end and provided at a position apart from the distal end face in order to displace living body tissue in front of the insertion part to secure a space for operating the distal end part of the endoscope protruded from the distal end face to curve; and a fixing portion that fixes the displacement part and the insertion part such that the distal end side of the displacement face intersects a direction orthogonal to the distal end face. | 09-13-2012 |
20130211433 | Endoscopic Vessel Dissector With Side Entry - A blunt dissector for endoscopic vein harvesting has a generally-cylindrical sheath for retaining an elongated endoscope. The sheath is elongated between a distal end and a proximal end. A transparent tip is disposed at the distal end of the sheath. | 08-15-2013 |
20140018630 | MEDICAL PORT - A medical port includes: a faceplate having a through-hole; a fixing ring formed in an annular shape and having an outer circumferential surface in which an outer diameter is gradually increased from a first opening end opened at a faceplate side toward a second opening end opened at an opposite side of the faceplate side; and a moving member connected to the fixing ring and the faceplate and configured to move the fixing ring with respect to the faceplate such that the fixing ring is pulled toward the faceplate. | 01-16-2014 |
20140155915 | GASTRIC THERAPY SYSTEM AND METHOD FOR SUTURING GASTRIC WALL - This gastric therapy system includes a loop-forming member that forms a loop along a lesser-curvature-line and a greater-curvature-line in a stomach; a guide member that introduces the loop-forming member into the stomach; and a therapy section that cerclages a part of the gastric wall after looping the loop-forming member. | 06-05-2014 |
