Publication number: 20110125282Abstract: Knee prostheses featuring components that more faithfully replicate the structure and function of the human knee joint in order to provide, among other benefits: greater flexion of the knee in a more natural way by promoting or at least accommodating internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. In a preferred embodiment, such prostheses include an insert component disposed between a femoral component and a tibial component, the insert component preferably featuring among other things a reversely contoured posterolateral bearing surface that helps impart internal rotation to the tibia as the knee flexes.Type: ApplicationFiled: November 23, 2010Publication date: May 26, 2011Inventors: Jason K. Otto, Brian McKinnon, Dean Hughes, Michael Ries, Jan Victor, Johan Bellemans, Jonathan Garino, Timothy Wilton

Publication number: 20110029116Abstract: A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.Type: ApplicationFiled: December 8, 2008Publication date: February 3, 2011Inventors: Jason Sean Jordan, Michael Dean Hughes, Mark Ellsworth Nadzadi, Brian W.

Patent number: 7758650Abstract: A modular humeral prosthesis for replacement of the humeral head of a humerus. The prosthesis generally comprises a stem to be fitted to a resected humerus; a head sized and configured to approximate the humeral head; and an intermediate connecting member for connecting the stem to the head. The intermediate connecting member provides a desired angle of inclination or offset between stem and head. The head may be a traditional humeral head, or it may be an eccentric humeral head, with its mating portion being offset. The head may also comprise a groove or milled trench at least partially surrounding or otherwise defining mating portion. Also disclosed is a modular humeral prosthesis kit comprising a variety of different intermediate connecting members that may be selected to fit the prosthesis to the patient, and a method of replacing a humeral head in a patient.Type: GrantFiled: February 6, 2007Date of Patent: July 20, 2010Assignee: Smith & Nephew, Inc.Inventors: Paul M.

Patent number: 7496037Abstract: A database server storing an authorization module and a rerouting module. The authorization module may be configured to define a second network interface module authorized to relay a response message queued in a hold queue associated with a first network interface module, where the response message is generated in response to a first request message. The rerouting module may be configured to route the response message from the hold queue to the second network interface module in response to a second request message requesting messages queued in the hold queue. The present invention thus enables delivery of requested queued messages despite failure of the request for such messages to correspond to the queue in which the messages are contained.Type: GrantFiled: June 14, 2005Date of Patent: February 24, 2009Assignee: International Business Machines CorporationInventors: Gerald Dean Hughes, Jack Chiu-Chiu Yuan

Patent number: 7472161Abstract: The present invention is a system for ensuring client access to paired and unpaired response messages. In the method, the server detects one or more unpaired message which are stored in a data structure on the server. The data structure may be created when the server is staffed or automatically when the first unpaired message is identified. The method then uses a communications protocol between the client and server which allows the client to request on or more of the stored unpaired messages. The system of the-present invention uses a request module configured to receive a client request and prepare the client request for a response generator. The response generator receives the client request from the request module and generates an appropriate response. Next, an unpaired message module analyzes the response message generated by the response generator and distinguishes a paired message from an unpaired message. Then, the unpaired message module stores paired messages in an unpaired response data structure.Type: GrantFiled: March 25, 2008Date of Patent: December 30, 2008Assignee: International Business Machines CorporationInventors: James Robert Davis, Gerald Dean Hughes, Steve T. Kuo, Thomas Clarke Morrison, Jack Chiu-Chiu Yuan

Patent number: 7308617Abstract: An apparatus, system, and method are provided for automatically freeing locked server resources using a timeout value closely related to actual real-time message delays plus a delta value that can be adjusted at a plurality of levels. The levels include default, server, connection, and transaction. The apparatus includes a timer, a communication module, a computation module, and a lock handler. The timer determines a timeout value for communications from a client to a server. The communication module sends an output message to the client and locks a server resource in anticipation of an acknowledgement (ACK) message from the client. The computation module, which calculates an ACK timer, includes a difference between a send time and a current time. If no ACK message has been received from the client and the ACK timer exceeds the timeout value, the lock handler may free the locked server resource.Type: GrantFiled: June 17, 2004Date of Patent: December 11, 2007Assignee: International Business Machines CorporationInventors: Michael Richard Artobello, Gerald Dean Hughes, Steve T.

Patent number: 7266622Abstract: A buffer accessible by an application executing under an application server in a first address space is managed by a database adapter executing in a second address space. A data request from the application executing in said first address space, comprising a buffer locator in the empty state, is received by the database adapter executing in the second address space. A buffer is allocated in the first address space and the address of this buffer is stored in the buffer locator. Data associated with the data request, received from a database subsystem, is copied to the buffer. Control is then transferred back to the application whereby the application utilizes the buffer locator to access the buffer and process the data contained therein. A database adapter automatically managing application buffers across address spaces in accordance with the present invention may be referred to as an “auto-buffer database adapter”.Type: GrantFiled: March 25, 2002Date of Patent: September 4, 2007Assignee: International Business Machines CorporationInventors: John Kevin Flanigan, Haley Hoi Lee Fung, Judith Eleanor Hill, Gerald Dean Hughes, Steve T.
