Patent number: 8417322Abstract: In a method for diagnosing or helping to diagnose a bone tissue condition of a patient, a portion of bone tissue of the patient is irradiated using a light source. The bone tissue may be irradiated in vivo through the skin or via an incision, for example. Alternatively, a biopsy of the bone tissue may be irradiated. Then, spectral content information for light scattered, reflected, or transmitted by the bone tissue is determined, and is used, at least in part, to determine whether the patient has a bone tissue condition.Type: GrantFiled: June 29, 2004Date of Patent: April 9, 2013Assignee: Regents of the University of MichiganInventors: Michael D. Morris, Steven A. Goldstein, Barbara R. McCreadie, Tso-Ching Chen

Publication number: 20120100107Abstract: The present invention relates to an in vivo method for specific targeting and transfer of DNA into mammalian repair cells. The transferred DNA may include any DNA encoding a therapeutic protein of interest. The invention is based on the discovery that mammalian repair cells proliferate and migrate into a wound site where they actively take up and express DNA. The invention further relates to pharmaceutical compositions that may be used in the practice of the invention to transfer the DNA of interest. Such compositions include any suitable matrix in combination with the DNA of interest.Type: ApplicationFiled: January 10, 2012Publication date: April 26, 2012Applicant: The Regents of the University of MichiganInventors: Steven A.

Patent number: 6270501Abstract: A surgical method and apparatus and cannulated scalpel for use therein are provided. In particular, the cannulated scalpel is used during surgical procedures to make an incision through intervening tissue about a guide pin having an end for engaging a target tissue, such as bone. The scalpel includes a hollow, elongated shaft adapted to slide over the guide pin and a head mounted at one end of the shaft. The head has at least one leading cutting edge that is adapted to cut along a plane through the intervening tissue as the shaft slides over the guide pin toward the target tissue engaging end of the guide pin. The scalpel can then be removed from the incision along the plane, preferably with the aid of a trailing guide edge. Following removal of the scalpel, a driving tool, such as a power surgical drill, can be introduced to drive a cannulated fastener along the guide pin and through the incision to embed the fastener in the target tissue and provide fixation of the target tissue.Type: GrantFiled: November 8, 1999Date of Patent: August 7, 2001Assignee: The Regents of the University of MichiganInventors: Andrew A. Freiberg, Steven A. Goldstein

Patent number: 4778473Abstract: An improved prosthesis interface surface is incorporated on any implantable component where stable long lasting bone fixation is needed. The surface achieves immediate stabilization of the prosthetic component and promotes bony tissue ingrowth by either making the surface of a porous metal or ceramic or coating the surface of the interface surface with a porous metal or ceramic. In the preferred embodiment, the surface includes a large number of conical protrusions which are specifically designed to resist shear and torsional disruptive forces while accommodating the compression loads that occur during motion of a joint prosthesis. By utilizing a series of conical protrusions, the surface contact area of the interface surface is much greater than interface surfaces now in use and this large surface contact area improves stability and provides a large area for secure bony ingrowth fixation.Type: GrantFiled: October 31, 1986Date of Patent: October 18, 1988Assignee: The University of MichiganInventors: Larry S. Matthews, Steven A. Goldstein

Patent number: 4741345Abstract: This invention provides a means of measuring tissue pressure in muscle compartments and other regions in humans and other animals. An appropriate length, for example, 6 to 12 inches of thin plastic tubing, typically less than 3 mm outside diameters, is prepared as a working part of the tissue pressure transducer. A portion of the plastic tubing including the thin wall section such as a bubble is inserted into the muscle tissue for which pressure measurement is desired to be made. A fluid is circulated through the tubing at a constant flow rate. When the internal pressure of the tubing is greater than the external pressure, the bubble expands and there is no increase in the flow resistance of the system. When the pressure on the outside exceeds the normal system operating pressure, the thin wall section or bubble contacts, resistance to flow increases, and the system pressure increases. This increase in system pressure is directly proportional to tissue pressure.Type: GrantFiled: August 4, 1986Date of Patent: May 3, 1988Assignee: Board of regents of the University of MichiganInventors: Matthews, Larry S., Steven A. Goldstein

Patent number: 4706659Abstract: Disclosed herein are embodiments of a flexible connecting shaft for an intramedullary reamer. In each embodiment, several short segments or links are attached together to form an elongated flexible shaft which shaft is designed, due to the specific attachment means for the links, to bend along its longitudinal axis while transmitting torque without any lag in such transmission. A link at one end of the flexible shaft as made by a plurality of the links includes means provided for attachment to a torque providing device such as an electric motor. At the opposite end of the shaft, the last link includes structure thereon enabling connection to a drill bit. The various embodiments disclose different ways of interconnecting the links.Type: GrantFiled: December 5, 1984Date of Patent: November 17, 1987Assignee: Regents of the University of MichiganInventors: Larry S.
