Patent number: 9072810Abstract: The present invention relates to uses of resorbable medical implants that are metallic or semi-metallic, to produce soft tissues, membranous tissues, organs or organ parts within the body by fibrosis. The present invention further relates to such uses when the implants are made of specified alloys or metals, e.g. magnesium and its alloys. The present invention further relates to such uses when the implant is surface modified. The present invention further relates to such uses when the implant is pre-implanted at another part of the body before implantation into the target site.Type: GrantFiled: March 6, 2012Date of Patent: July 7, 2015Assignee: THE UNIVERSITY OF HONG KONGInventors: Wing Yuk Ip, Chi Keung Yuen

Patent number: 6908467Abstract: A fixation device for internally or externally fixing fractures comprising at least one nitinol wire having an S-shaped section and two ends wherein each of said two ends forms a hook for hooking into a bone section of a fractured bone. This device can be made from nitinol which has a transformation temperature between 25° C. and 35° C. In addition, this device can have a diameter between 0.6 mm and 5 mm. The device can be inserted using the following process which starts by cooling the wire below a transfer temperature such that the nitinol wire forms in a martensite state. Next, the nitinol wire is inserted into a interphalangeal bone underneath a patients skin. Next, the nitinol wire to heats up inside a patients body above the transfer temperature. Finally, the wire transforms wire from a martensite state to an austenite state wherein when the nitinol wire elongates in a longitudinal direction to generate a distraction force.Type: GrantFiled: May 14, 2003Date of Patent: June 21, 2005Assignee: The University of Hong KongInventors: Wing Yuk Ip, Daniel Cheng Chi Hang

Patent number: 6652530Abstract: The present invention relates to a fixation device for internally fixing fractures. The fixation device has an elongated support plate and a transverse plate and a fin member extending transversely from the elongated support plate. The elongated support plate and the transverse plate define a plurality of holes for receiving fixing elements to mount the fixation device onto a bone. The holes can be so located that the fixing elements can prevent the fixation device from rotating relatively to the bone after the fixation device is mounted onto the bone. Additionally, the fin member is formed to be more flexible than the transverse plate. Thereby, the fin member can be bent to conform to the contour of the bone for fixing or stabilizing a fractured fragment. As a result, the fixation device can both support the injured bone and fix/stabilize the fractured fragment.Type: GrantFiled: September 19, 2001Date of Patent: November 25, 2003Assignee: The University of Hong KongInventors: Wing-Yuk Ip, Ting-Lai Lau
