Patent number: 10245021Abstract: A suturing device is made of two hypodermic needles allowing one or more sutures (at the same time) and a retrieval probe to be advanced into a cavity (e.g., a stomach cavity) of the patient. Both the suture and retrieval probes comprise magnets of opposite polarities on their leading ends. Thus, after the suture and retrieval probe are inside the stomach cavity, the suture and retrieval probe may mate and the suture may be transferred from one hypodermic needle to the other using magnetic attraction. In doing so, the suture forms a loop through the stomach. Once removed, this loop, having two ends that are positioned outside the patient's body, can be pulled tight in order to pull the stomach wall closer to the surface of the patient's body. With the stomach wall close to the surface of the patient's body, it is easier to insert a gastrostomy device.Type: GrantFiled: August 8, 2014Date of Patent: April 2, 2019Assignee: APPLIED MEDICAL TECHNOLOGY, INCInventors: Grant Wesley Phillips, Derek M.

Patent number: 9247936Abstract: Methods and devices are provided for securing tissue to bone. In general, a suture leader can have leading and trailing ends, and an inner passageway configured to receive a strand of suture therein. More specifically, the trailing end of the leader can be configured to receive the strand of suture therein to form an overlapping region of suture leader and suture. When the suture is positioned in the leader, an outer diameter of the leading end of the leader can be less than an outer diameter of the over lapping region. The leader can have a lower bending stiffness than the suture so that the leader can be more easily folded into a bend. In certain aspects, the suture leader can be formed from a substantially flexible, braided material so that the leader can be configured to contract when a pulling force is applied to the leader. In another embodiment, the suture leader can have a pre-formed crease configured to mate with a threading tool.Type: GrantFiled: September 20, 2012Date of Patent: February 2, 2016Assignee: MEDOS INTERNATIONAL SARLInventors: Mehmet Z.

Patent number: 8652173Abstract: Knotless suture anchors are disclosed for surgical use, which contain one or more types of ratcheting mechanisms that will allow a surgeon to pull a suture strand through an anchor device in one direction, without allowing the suture strand to travel or creep backward, in the other direction. This will allow a surgeon to emplace a number of such anchors in hard bone(s) or soft tissue(s), during installation of an implant device, while the various suture strands remain loose and do not interfere with proper positioning of the implant. When the implant device is roughly in position, the surgeon can gently “snug” all of the suture strands (which preferably should be braided, to provide a non-smooth surface that will enable a stronger and more secure grip by the ratcheting mechanism), so that they will all reach a moderate plateau of gentle yet firm tension.Type: GrantFiled: January 20, 2012Date of Patent: February 18, 2014Assignee: Formae, Inc.Inventor: Kevin A.
