Patent number: 11864978Abstract: A computer-implemented bone-implant system evaluation method for application of mesh-free analysis of a bone-implant system for evaluation of performance of a bone-implant system for an implant implanted within the bone structure at an anatomical site, said method comprising (i) receiving a set of bone structure data set, wherein set of bone structure data includes data indicative of the bone structure at an anatomical site; (ii) inputting an implant data set and inputting the position of the implant data set, wherein the implant is selected based upon the biomechanical requirements for the anatomical site and the position and of the implant data set is indicative of the position of the implant with respect to the anatomical site, wherein implant data set includes data representative of the geometry and materials properties of the implant; (iii) creating a bone-implant model, wherein said bone implant-model includes a mesh-free model of trabecular bone at the anatomical site wherein the bone-implant model isType: GrantFiled: September 7, 2017Date of Patent: January 9, 2024Assignee: VERSITECH LIMITEDInventors: Sloan Austin Kulper, Hing Wan Alfonso Ngan, Xinshuo Christian Fang, Margaret Guo, Weijia William Lu, Ka Li Frankie Leung

Publication number: 20230210568Abstract: A fixation system (900) for the fixation of a first bone fragment (932) relative to a second bone fragment (934); the fixation system (900) comprising at least one first bone engagement element engagable with the first bone fragment (932), wherein the first bone engagement element has an elongate body portion, a proximal end, a distal end, and a passageway extending through the body portion from the proximal end to the distal end, at least one further bone engagement element engageable with the second bone fragment (934) and having a tensile element (920) securement portion for affixing a tensile element (920) to the further bone engagement element; wherein the tensile element (920) passing the first bone engagement element when engaged with the first bone fragment (932) is fixed relative to the further bone engagement element when engaged with the second bone fragment (934) by the tensile element (920) securement portion; such that the first bone fragment (932) is affixed relative to the second bone fragmentType: ApplicationFiled: May 8, 2021Publication date: July 6, 2023Applicant: LIFESPANS LIMITEDInventors: Christian Xinshuo FANG, Erica Ann BOLES, Man Chuen LEUNG, Sloan Austin KULPER, Ka Li Frankie LEUNG, Ahmed Abbas ALVI, Marilyn Janice OENTARYO, Mohd Rezaul Karim THARIM

Patent number: 10966842Abstract: Devices and methods for the removal of bone implant tips from within a bony structure in a body. The device or method includes a shaft with an internal grasping feature capable of being inserted while remaining in an un-expanded, un-deployed state. This permits a surgeon or operator to insert the device while in a small profile state, avoiding or reducing damage to adjacent bone tissue during insertion. Upon insertion of the shaft to the proper position within a patient's bone, the grasping feature may then be expanded or deployed from the distal end of the shaft by a surgeon or operator using an actuator in a handle attached to the proximal end of the shaft. Following deployment, the grasping feature may be used to manipulate and/or remove a bone implant tip from a patient's bone tissue. Embodiments of the grasping feature include one or more hooks, wires, articulating fingers, and/or net-based designs formed of metal, polymer, composite, or a combination thereof.Type: GrantFiled: July 11, 2018Date of Patent: April 6, 2021Assignee: The University of Hong KongInventors: Sloan Austin Kulper, Erica Ann Boles, Xinshuo Christian Fang, Ka Li Frankie Leung, Weijia William Lu

Patent number: 10799277Abstract: A device for engagement with a bone includes a dynamically expandable tip (12), a dynamically expandable ring (40), or other dynamically expandable insert (60, 62, 401L) that reacts to forces pushing the implant into bone tissue. The tip (12), ring (40) or insert (60, 62, 401L) expands at least normal to the direction of motion, increasing contact area between the surrounding bone tissue and the material and thereby reducing the occurrence of high areas of contact stress in the adjacent bone tissue. The tip (12), ring (40) or insert (60, 62, 401L) translates forces along an axis of motion into lateral frictional forces that can resist penetration into the bone tissue without the need for additional operator or patient interaction. A method of reducing migration of the device for engagement includes the steps of providing the device and inserting the device within bone tissue.Type: GrantFiled: April 1, 2016Date of Patent: October 13, 2020Assignee: VERSITECH LIMITEDInventors: Sloan Austin Kulper, William Weijia Lu, Frankie Ka Li Leung, Christian Xinshuo Fang
