Patent number: 8753398Abstract: A method of inserting an expandable intervertebral implant between vertebrae of a human spine without overdistraction of the vertebrae is described. The method includes removing a portion of a disc between the vertebrae to create a disc space between the vertebrae. The unexpanded intervertebral implant may be positioned in the disc space. The intervertebral implant may be expanded to increase a height of the intervertebral implant, thereby increasing a separation distance between the vertebrae or a separation distance between an upper body and a lower body of the intervertebral implant. The increased height of the intervertebral implant may be maintained at substantially the expanded height, wherein the maximum separation distance between the two vertebrae during the procedure is the separation distance created during expansion of the intervertebral implant.Type: GrantFiled: May 20, 2005Date of Patent: June 17, 2014Inventors: Charles R.

Patent number: 8535282Abstract: The present disclosure is directed at methods and apparatus to evaluate and monitor healing progress of wound and/or to generate data to modify or identify a treatment protocol. Fluid exudate removed from the wound by a negative pressure therapy device may now be analyzed to identify the progress of wound healing, such as whether healing is progressing in a positive manner or experiencing one or more impediments. The fluid exudates may be specifically analyzed for one or more analytes indicative of one or more of the biochemical reactions that may occur during wound recovery. In addition, one may separately utilize optical sensors integrated into a dressing enclosure, optionally in those dressings employed in a negative pressure therapy device. Such optical sensors may then illuminate the wound and collect information regarding the wound via a light scattering type response.Type: GrantFiled: July 14, 2009Date of Patent: September 17, 2013Assignee: Southwest Research InstituteInventors: Heather S.
