Patent number: 8518078Abstract: 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 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: March 9, 2012Date of Patent: August 27, 2013Inventors: Marlen Andreevich Sulamanidze, Georgiih Marlenovich Sulamanidze, Constantin Marlenovich Sulamanidze

Patent number: 8480689Abstract: A surgical suturing device has a grasper device that is translatable within an outer lumen where a first end of a needle is grasped with the grasper device. The needle may be resilient to a curved resting state. The grasper device translates proximally relative to the outer lumen such that the needle is translated into the outer lumen, wherein the outer lumen tends to straighten the needle from the curved resting state. The grasper device may be translated distally relative to the outer lumen such that a second end of the needle extends distally from the outer lumen and pierces the tissue. The needle may return to the curved resting state as it exits the outer lumen. When a second end of the needle emerges from the tissue, the second end of the needle may be grasped with the grasper device.Type: GrantFiled: September 2, 2008Date of Patent: July 9, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: James T. Spivey, Kempton K. Carroll, II, David B. Griffith

Patent number: 8366845Abstract: An apparatus for thermally treating a plurality of curved suture needles. The apparatus includes a conveyer for transferring the plurality of curved suture needles from a source of curved suture needles to a receiver, a housing positioned adjacent the conveyer, the housing having a first end, a second end, and an opening running from the first end to the second end, the opening aligned with the conveyer to enable the plurality of curved suture needles to pass therethrough, and a heat source located within the housing for heating the plurality of curved suture needles as the plurality of curved suture needles are transferred by the conveyer from the first end of the housing to the second end of the housing. Also provided is a process for thermally treating a plurality of curved suture needles to enhance the stiffness and yield moment of the curved suture needles. The curved suture needles so treated have a desirable combination of stiffness, strength and ductility.Type: GrantFiled: August 12, 2011Date of Patent: February 5, 2013Assignee: Ethicon, Inc.Inventors: Frank Richard Cichocki, Jr., David DeMarest, Gregory Hollin, Eugene D.

Publication number: 20130023927Abstract: A whip stitched graft construct and method of formation. The whip stitched graft construct includes a plurality of tendon strand regions or soft tissue grafts placed together so that at least a portion of the plurality of the tendon strand regions are stitched together by employing multiple suture passes placed according to a whip stitching technique. Preferably, the multiple suture passes start at about the mid length of the plurality of tendon strand regions and are advanced toward one of the free ends of the tendon strands. The whip stitched graft construct is provided with at least two regions, one region formed of at least a plurality of tendon strand regions tied and whip stitched together, and the other region formed of untied segments of the plurality of tendon strands.Type: ApplicationFiled: September 25, 2012Publication date: January 24, 2013Inventor: Mark A. Cassani

Patent number: 8292920Abstract: A surgical needle which is particularly suited for use in limited space applications and a method for its use are disclosed. The surgical needle generally includes an arcuate portion having a first end and a second end. A pointed tip is disposed near the first end. There is a relatively short, straight shank near the second end of the arcuate portion which extends from the arcuate portion at a predetermined angle. The predetermined angle is defined by the intersection of the arcuate portion and the shank. This predetermined angle is within a range of about 23° to about 29°. In a particularly useful embodiment, the predetermined angle is approximately 26°. Further, an extrapolation of a longitudinal axis of the shank intersects the arcuate portion of the surgical needle.Type: GrantFiled: November 10, 2005Date of Patent: October 23, 2012Assignee: Tyco Healthcare Group LPInventors: Reza Dabir, Michael Primavera, Gregg Krehel
