Patent number: 8192462Abstract: A surgical suture material and a method to the use thereof are represented by different needles and surgical threads. The main embodiments comprises a needle (6), consisting of two needles (7, 8) jointed by a temporary connection having a tetrahedral, diamond or another shape in such a way that a single needle point (9) is formed, and a surgical thread (10) provided with shaped design projections embodied on the thread surface in the form of notches. The shaped design of the notches has a very important significance since it makes it possible to provide a reliable linkage with soft tissues and to forcedly holding the soft tissues when force actions are applied thereto. The method consists in introducing, during a surgical intervention, the twin needle in one puncture at a small depth, wherein the needle is divided into two needles, and in leading each needle along a required contour. The surgical suture material can be extensively used for surgical and cosmetic interventions.Type: GrantFiled: May 16, 2006Date of Patent: June 5, 2012Inventors: Marlen Andreevich Sulamanidze, Georgiih Marlenovich Sulamanidze

Patent number: 7922744Abstract: A suture punch system that is capable of directly passing braided suture through tissue in a simple, one-step process. The system includes three principle components: a malleable needle capable of delivering the suture to the tissue, a handheld instrument for grasping tissue and controlling needle placement, and a force-supplying mechanism to supply the force required for needle placement. Needle deformation begins at the tip of the instrument, which beneficially includes a curved segment. As the distal tip of the needle pierces the tissue, it continues its radial path through the tissue. When the proximal end of the needle exits from the instrument, the needle may be radial in shape and traverses an essentially radial path through the tissue. Once the needle has passed entirely through the tissue, it may be retrieved using the jaws of the punch or another instrument.Type: GrantFiled: November 27, 2006Date of Patent: April 12, 2011Inventors: John K.

Publication number: 20090318958Abstract: The invention relates to a method of suturing. Briefly, a portion of a needle having a continuous suture thread running through the eye is advanced through a first location on a first side of a tissue. When the needle is withdrawn from said tissue a suture loop is retained on a second side of said tissue. This can be repeated to obtain as many suture loops as desired on additional locations of the tissue. When all the desired suture loops are formed the needle is advanced all the way through the tissue and a single strand of suture thread is passed through each suture loop on the second side of the said tissue. Thus, one continuous suture forms the suture loop(s) and engages the sutured loops. In a preferred embodiment the needle eye, through which the suture thread runs, is located in the tip portion of said needle. It is also preferred that the needle is curved. The tissue may be, for example, a tendon (e.g., patellar), a ligament, or a graft.Type: ApplicationFiled: June 17, 2009Publication date: December 24, 2009Inventor: Derek H. OCHIAI

Publication number: 20090216268Abstract: A suture for facilitating tying of knots includes a length of suture material fixed to a needle. At least part of the length of the suture material is resiliently biased to a coiled state which is straightenable under applied tension but which returns to its coiled state when released. In use, part of the suture material is drawn through a region of tissue so that portions of the suture material lie on opposite sides of the tissue. A knot is then formed in the suture material by passing one of the portions through at least one resiliently-formed coil formed in the other of the portions, and pulling tight the suture material.Type: ApplicationFiled: February 21, 2008Publication date: August 27, 2009Inventor: Gideon G.

Patent number: 7572253Abstract: In order to rotate and move an arm of a slave which supports a needle-holder, the rotation and movement of a pen-shaped operating section (31) caused by the fingers of the operator's hand are directly transmitted as the rotation and movement of the needle-holder, as sensors for detecting the rotation and movement of the operating section, an X-axis torque sensor, Y-axis torque sensor, Z-axis torque sensor, and a rotation detecting potentiometer (33) are installed thereon. As a result, the rotation and movement of the pen-shaped operating section (31) caused by the fingers of the operator's hand are transmitted as the rotation and movement of the needle-holder in optimum proportions through a computing section. Therefore, when the needle-holder is to be finely moved, a subtle motion of the fingers of the hand can be satisfactorily transmitted. Thereby, it is possible to provide a surgical operation device capable of doing minute surgical operations with ease.Type: GrantFiled: March 24, 2004Date of Patent: August 11, 2009Assignee: Japan Science and Technology AgencyInventor: Hiroyuki Gotani

Publication number: 20090171141Abstract: In one embodiment, a medical device includes a support portion having a first end portion and a second end portion opposite the first end portion. An elongate member extends from the first end portion of the support portion and has a length sufficient to extend from the first end portion of the support portion to a location above a pubic bone when the support portion is disposed between the bladder and a vagina of the patient. An elongate member extends from the second end portion of the support portion and has a length sufficient to extend from the second end portion of the support portion and through an obturator membrane of the patient when the support portion is disposed between the bladder and the vagina of the patient.Type: ApplicationFiled: December 22, 2008Publication date: July 2, 2009Inventor: Michael S. H. Chu

Publication number: 20090163950Abstract: A surgical instrument comprises two elongated arms terminating in a finger ring and a jaw for holding a needle. The arms are pivotably fastened to each other and a scissors member that includes a finger ring and a cutting edge proximate the scissors member second end. The arms can be locked together by a pair of interengageable clasps having a plurality of projections, which interlock when the clasps are engaged. A stop member attached to one arm limits the scissors member's movement. When the device is in a closed position, a needle is retained between the jaws, the needle being attached to a length of suture material. The device is used to place the suture, tie the suture, and the scissors member is opened, and then used to cut the untied suture material after the suture has been tied.Type: ApplicationFiled: December 20, 2007Publication date: June 25, 2009Inventor: Peter J. Waldman

Publication number: 20090131979Abstract: Disclosed is a wound closure device, such as a suture, including a substantially flexible tensile member, the tensile member having an external surface, the external surface including a biocidal material such as a coating of substantially pure silver. A method of applying the suture includes piercing a patient's skin adjacent to a wound using, for example, a needle and drawing a substantially flexible tensile member through a resulting aperture in the skin. By virtue of the biocidal material, pathogens and other bioactive materials drawn through the aperture are rendered less active and/or incapable of causing infection.Type: ApplicationFiled: July 17, 2008Publication date: May 21, 2009Inventors: G. Alan Thompson, Richard Edward Brois, SR., Christopher Matthew Scheuerman, SR., David Curry Pitts, JR.

Patent number: 7527590Abstract: There is provided an endoscopic system. The system comprises a flexible endoscope insertable into a first tubular organ from a natural opening of a human body. The system further comprises an opening member which forms on a wall part of the first tubular organ an opening used to insert the endoscope into an abdominal cavity from the first tubular organ in the body, an anastomosing member which is able to anastomoses the first tubular organ with a second tubular organ in the abdominal cavity, and a cutting member with which the second tubular organ is able to be cut.Type: GrantFiled: March 17, 2003Date of Patent: May 5, 2009Assignee: Olympus CorporationInventors: Keita Suzuki, Tetsuya Yamamoto, Yoshio Onuki, Satoshi Miyamoto, Masahiro Ishikawa, Anthony Nicholas Kalloo, Sergey Veniaminovich Kantsevoy, Pankaj Jay Pasricha, Sydney Sheung Chee Chung
