Publication number: 20090098593Abstract: A portable temperature transfer device for transferring thermal energy to and/or from a laboratory plate is provided as well as its methods of use. The temperature transfer device comprises a base and a raised stage that comprises a thermal conductive material and an encasement that interfaces with the base to create a cavity that encloses a laboratory plate. The raised stage allows direct contact between individual wells of the laboratory plate and the temperature transfer device. The encasement completes the thermally conductive environment for the laboratory plate.Type: ApplicationFiled: May 30, 2008Publication date: April 16, 2009Applicant: Biocision, Inc.Inventors: Rolf Ehrhardt, Brian Schryver, Jeff Schryver

Patent number: 6630153Abstract: The present invention is directed to methods and compositions for manufacturing a bone graft substitute. A powder compaction process is utilized to generate a shaped product comprised of a granulated bone material, such as demineralized bone matrix. In addition, a processing aid is utilized to facilitate compaction of the granulated bone material and for release of the product from the die.Type: GrantFiled: February 23, 2001Date of Patent: October 7, 2003Assignee: Smith & Nephew, Inc.Inventors: Marc Long, Michael B. Cooper, Keith M. Kinnane, Trevor Allen, Jeff Schryver

Publication number: 20030036761Abstract: This invention relates to methods, devices, and systems for preventing complications, including for example, infection associated with any percutaneous or external fixation of bones by placing a pharmacological sleeve over an external fixation element. The pharmacological sleeve may be comprised of a polymer sleeve having one or more internal splines along at least part of the inner surface of the sleeve. The sleeve may be suffused or coated on any or all surfaces with a pharmacological coating which allows accumulation of drugs in the tissue surrounding the external fixation element, thereby reducing potential complications.Type: ApplicationFiled: July 3, 2002Publication date: February 20, 2003Inventors: Crista Smothers, John Schneider, Ed Austin, Ajit Mishra, Mark Gosney, Anthony James, David Castleman, Mark Hamby, Julie Bearcroft, Jeff Holbrook, Jeff Schryver, Michael Cooper

Patent number: 5534005Abstract: An in-situ surgical orthopedic milling apparatus includes an instrument frame having upper and lower end portions. A plurality of templates are provided, each forming a respective virtual pattern. A cutting device supported upon the frame cuts bone tissue (e.g., within the intramedullary canal of a patient's bone), by tracking the virtual patterns. A system of vertically stacked templates can be placed in position with respect to the instrument frame to define an operative position. The templates provide a wall portion that constrains movement of the cutting tool beyond a desired surgical cutting area defining an "actual pattern". In this first embodiment, the templates are in the form of stacked templates, each template having its own pattern.Type: GrantFiled: October 5, 1994Date of Patent: July 9, 1996Assignee: Smith & Nephew Richards, Inc.Inventors: Leonard J. Tokish, Jr., Thomas W. Fallin, Jeff Schryver

Patent number: 5507830Abstract: A modular hip prosthesis can be custom fitted to a particular patient by a surgeon prior to surgical insertion. The prosthesis features a body having a neck portion for carrying a rounded head element, a transitional mid-section of the prosthesis body includes generally rectangular and generally rounded cross-sectional areas, and a stem section has a generally rounded cross-sectional area. The stem is tapered to receive a tubular extension sleeve with a hollowed portion corresponding in shape to the stem portion of the prosthesis. The tubular extension sleeve has an open end portion receptive of the lower tapering stem of the prosthesis body. The stem portion includes an internal bore, and an attachment in the form of an elongated screw is provided for connection to the stem internal bore for securing the extension sleeve and the prosthesis body together, forming a compressive sealed connection therebetween.Type: GrantFiled: September 28, 1993Date of Patent: April 16, 1996Assignee: Smith & Nephew Richards Inc.Inventors: Michael DeMane, Thomas W. Fallin, Steve Garner, Jeff Schryver, Robert Brosnahan

Patent number: 5314487Abstract: An improved acetabular cup prosthesis has a cup body with a plurality of bores extending between an inner concave surface and an outer convex surface, wherein the bores can function as drill guides for providing alignment in the drilling of surgical openings after the acetabular cup body is placed in a patient. A plurality of pegs or spikes have proximate end portions that have connection members for forming connections with the bores, and distal end portions that can register into the drilled surgical openings.Type: GrantFiled: February 10, 1992Date of Patent: May 24, 1994Assignee: Smith & Nephew Richards Inc.Inventors: Jeff Schryver, Jeff Shea, Dawn M. Ryan

Patent number: 5310408Abstract: An improved acetabular cup prosthesis has a cup body with correspondingly shaped inner convex and outer concave surfaces. A polymer liner fits and attaches to the cup at the concave surface. The inner convex surface is highly polished and mirror-like, for retarding debris generation with the polymer liner and allowing optical pattern inspection. A plurality of bores can be provided, extending between an inner concave surface and an outer convex surface, wherein the bores can function as drill guides for providing alignment in the drilling of surgical openings after the acetabular cup body is placed in a patient. A plurality of pegs or spikes have proximate end portions that have connection members for forming connections with the bores, and distal end portions that can register into the drilled surgical openings.Type: GrantFiled: August 31, 1992Date of Patent: May 10, 1994Assignee: Smith & Nephew Richards Inc.Inventors: Jeff Schryver, Jeff Shea, Dawn M. Ryan
