Publication number: 20200222097Abstract: Various exemplary methods, systems, and devices for blood flow are provided. In general, an implant can be configured to be implanted in bone and to delay clotting of blood flowing from the bone. The implant can include an anti-coagulation agent to delay the clotting of the blood. The anti-coagulation agent can be a coating on the implant, can be natural to a material forming the implant, or can be impregnated into a material forming the implant. In an exemplary embodiment, the implant is implanted in a bone in a surgical procedure for securing a soft tissue to bone, such as a rotator cuff repair procedure or an anterior cruciate ligament (ACL) repair procedure.Type: ApplicationFiled: April 1, 2020Publication date: July 16, 2020Inventors: Gregory R.

Patent number: 10702260Abstract: Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture, and can be useful in many different tissue repair procedures that are disclosed in the application. In one exemplary embodiment, one or more constructs are disposed on a suture threader, which can be used to associate the construct(s) with a repair suture(s) being used to repair the soft tissue. Tissue augmentation constructs can include various blocks and patches, among other formations. Exemplary methods for manufacturing the tissue augmentation constructs are also provided.Type: GrantFiled: January 30, 2017Date of Patent: July 7, 2020Assignee: MEDOS INTERNATIONAL SÀRLInventors: Mehmet Ziya Sengun, Gregory R.

Patent number: 10518275Abstract: A method provides for procuring platelet rich plasma (PRP) from a sample of whole blood in a vial. The method includes the steps of: separating the whole blood into layers through centrifugation with an upper layer containing platelet poor plasma (PPP) and a PRP layer below the upper layer containing PRP; adjusting an end point of a first range of motion of an extractor relative to a position of the PRP layer; moving the extractor through the first range of motion through the vial, PPP passing out from the upper layer through the extractor; and after the extractor reaches the end point of the first range of motion, extracting the PRP through the extractor and collecting the PRP.Type: GrantFiled: January 3, 2017Date of Patent: December 31, 2019Assignee: DePuy Synthes Products, Inc.Inventors: Mehmet Ziya Sengun, William Parrish, Brooks J.

Patent number: 10117698Abstract: In general, devices, systems, and methods for driving an anchor into bone are provided. In one embodiment, a surgical tool is provided that includes a driver tool with a handle and an elongate shaft. A resistance element is disposed within the handle. An inner portion of an anchor is retained on a distal end of the elongate shaft, and a guidewire extends between the resistance element and an outer portion of the anchor that is in bone. As force is applied distally to the handle, the guidewire pushes the anchor into the bone before overcoming force of the resistance element and thereby allowing the inner portion of the anchor to be driven into the outer portion of the anchor.Type: GrantFiled: March 1, 2016Date of Patent: November 6, 2018Assignee: MEDOS INTERNATIONAL SARLInventors: Gregory R.
