Publication number: 20100233669Abstract: An antibiotic composition is provided for use in decontaminating biological tissue, for example, graft tissues for transplantation or preparation for terminal sterilization. The antibiotic composition is a physiological solution includes a lantibiotic, such as nisin. The antibiotic solution is effective to substantially inhibit bacterial growth of at least one type of gram-positive bacteria while substantially maintaining the physiological characteristics of the tissue. The method may include contacting the tissue with the antimicrobial composition at a temperature and for a period of time effective to substantially inhibit bacterial growth of the at least one type of gram-positive bacteria while substantially maintaining the physiological characteristics of the tissue.Type: ApplicationFiled: March 11, 2010Publication date: September 16, 2010Applicant: CRYOLIFE, INC.Inventors: Steven Walsh, Joseph Hamby, Chad Chinich

Patent number: 7129035Abstract: This invention relates to the sterilization and preservation of tissue for storage. More specifically, the invention relates to a method of using a solution to form a preserved tissue. The solution includes a radical scavenger at a concentration believed to reduce the damage to the tissue that could otherwise occur during sterilization with ionizing radiation.Type: GrantFiled: December 11, 2003Date of Patent: October 31, 2006Assignee: CryoLife, Inc.Inventors: Steven Goldstein, Joseph Hamby, Steven P. Walsh, Kirby S. Black

Patent number: 6994382Abstract: A retaining feature is provided for connecting a plastic tube to a corrugated acoustic duct. The retaining feature accommodates variations in the undulations and thread pattern of the corrugated duct, while at the same time minimizing the materials, specialized equipment or tools, labor and cost of making a successful connection. The retaining feature includes at least one barb extending circumferentially around the exterior surface of the plastic tube. Each barb is sized and structured to engage an undulation of the corrugated duct.Type: GrantFiled: July 1, 2004Date of Patent: February 7, 2006Assignee: Visteon Global Technologies, Inc.Inventors: Charles Bryan Peterson, Stephen Joseph Hamby, Milap Kanu Shah

Patent number: 6824119Abstract: A throttle body for use in the air intake system of a motor vehicle comprising a throttle body defining a throttle bore. The throttle plate is rotatably mounted within the throttle bore, having an outside diameter smaller than an inside diameter of the throttle bore. A plurality of fins, located on the throttle plate, extend from the throttle plate in a direction generally perpendicular to a plane defined by said throttle plate. The fins are optimized in number, thickness, spacing, length, shape, and angle to reduce air-rush noise without impacting engine performance.Type: GrantFiled: August 20, 2002Date of Patent: November 30, 2004Assignee: Visteon Global Technologies, Inc.Inventors: David A. Conley, Christopher Edward Shaw, Stephen Joseph Hamby

Patent number: 5797589Abstract: A throttle body (12), for an air intake system of a vehicle, including a housing (14) formed of a thermoplastic material and including a pair of throttle shaft bearing pockets (24, 26) extending from a main bore (16) of the throttle body. The bearing pockets (24, 26) each include a generally cylindrical wall (34) of a diameter to allow for a press fit of throttle shaft support bearings (28, 30) therein. After insertion, a swaging process secures the bearings (28, 30) into the pockets (24, 26) by forming lips (40) around the bearings. The walls (34) may include axial grooves (36) to allow for a more controlled swaging operation.Type: GrantFiled: July 9, 1997Date of Patent: August 25, 1998Assignee: Ford Motor CompanyInventors: Christopher Joseph Kalebjian, Stephen Joseph Hamby, Wade Coots
