Patent number: 10363141Abstract: An artificial disc to replace a damaged spinal disc in a spinal column includes a resilient core which is fixedly connected to first and second plates. The first and second plates engage upper and lower vertebra in the patient's spine. The inner side of at least one of the first and second plates has an array of recesses into which said resilient core extends. The array of recesses includes a plurality of recesses. Each of the recesses of the plurality of recesses has surfaces which are integrally formed as one piece with the plate.Type: GrantFiled: March 17, 2014Date of Patent: July 30, 2019Assignee: AXIOMED, LLCInventors: Kari Zimmers, Keith Duke, James Kuras, Rebecca Blice, J. Edward Barber, Tawny Brag

Publication number: 20180207027Abstract: Example heat exchange pads are described herein. A heat exchange pad can include an input compartment, an output compartment arranged in fluid connection with the input compartment, and an internal member disposed between the input and output compartments. The internal member can include an array of holes formed therein. Additionally, the internal member can be configured to produce impinging flow convection heat transfer in proximity to a heat exchange surface of the output compartment.Type: ApplicationFiled: January 25, 2018Publication date: July 26, 2018Inventors: Kenneth R. Diller, Gary L. McGregor, Dale Wagner, Jon Harvey, Brad Pulver, James Kuras

Publication number: 20060149273Abstract: A method for replacing a spinal disc between first and second vertebrae of a spinal column includes determining a reference point on the spinal column. A marker is connected to a vertebra of the spinal column at the reference point. The marker is engaged with a guide assembly for guiding insertion of a surgical instrument between the first and second vertebrae to prepare the space between the first and second vertebrae for receiving an apparatus between the first and second vertebrae. The apparatus is inserted between the first and second vertebrae. The apparatus has a first end, a second opposite end, and first and second lateral sides extending between the first and second ends. An outer surface is engageable with the first vertebra of the spinal column. A rail extending from the outer surface is engageable with the first vertebra to connect the apparatus to the first vertebra. The rail extends a first distance from the outer surface adjacent the first end.Type: ApplicationFiled: December 6, 2005Publication date: July 6, 2006Inventors: Raymond Ross, Isador Lieberman, Edward Benzel, Lee Strnad, Keith Duke, James Kuras, Kari Zimmers, Charles Birchall

Publication number: 20050131543Abstract: An apparatus for replacing a damaged spinal disc in a spinal column includes an artificial disc. The artificial disc includes a resilient core having a first surface and a second surface, a first retaining member connected to the first surface of the resilient core, and a second retaining member connected to the second surface of the resilient core. The first retaining member has an outer surface engageable with a first vertebra of the spinal column and an inner surface facing the first surface of the resilient core. The second retaining device has an outer surface engageable with a second vertebra of the spinal column and an inner surface facing the second surface of the resilient core. A first mounting member is connectable with the first vertebra and the artificial disc to position the artificial disc between the first and second vertebrae.Type: ApplicationFiled: December 10, 2003Publication date: June 16, 2005Inventors: Edward Benzel, Isador Lieberman, Lee Strnad, James Kuras, Raymond Ross, Charles Birchall, Keith Duke, Kari Zimmers

Publication number: 20050131542Abstract: A method for replacing a damaged spinal disc between first and second vertebrae of a spinal column includes connecting a first mounting member with the first vertebra of the spinal column. An artificial disc is moved between the first and second vertebrae and into engagement with the first mounting member to guide the artificial disc into position between the first and second vertebrae. The artificial disc includes a resilient core having a first surface and a second surface, a first retaining member connected to the first surface of the resilient core, and a second retaining member connected to the second surface of the resilient core. The first retaining member has an outer surface engageable with a first vertebra of the spinal column and an inner surface facing the first surface of the resilient core. The second retaining member has an outer surface engageable with the second vertebra of the spinal column and an inner surface facing the second surface of the resilient core.Type: ApplicationFiled: December 10, 2003Publication date: June 16, 2005Inventors: Edward Benzel, Isador Lieberman, Lee Strnad, James Kuras, Raymond Ross, Charles Birchall, Keith Duke, Karl Zimmers

A first retaining device is connected to the first surface of the resilient core. The first retaining device includes an outer surface engageable with a first vertebra of the spinal column and an inner surface facing the first surface of the resilient core. A second retaining device is connected to the second surface of the resilient core. The second retaining device has an outer surface engageable with a second vertebra of the spinal column and an inner surface facing the second surface of the resilient core. The inner surface of the first retaining device is spaced from the core. The core deflects into engagement with the inner surface of the first retaining device upon relative movement between the first and second retaining devices.Type: ApplicationFiled: December 10, 2003Publication date: June 16, 2005Inventors: James Kuras, Lee Strnad, Keith Duke, Kari Zimmers, Edward Benzel, Isador Lieberman, Raymond Ross, Charles Birchall

Patent number: 6669732Abstract: A spinal disc prosthesis (10) to replace a damaged spinal disc in a spinal column (16) of a human, includes an elastomeric core (200) having upper and lower surfaces (202, 212) which are parallel to each other. An upper rigid plate (20) has opposed first and second surfaces (42, 52). The first surface (42) is affixed to the upper surface (202) of the elastomeric core. The second surface (52) is inclined relative to the first surface (42). A lower rigid plate (120) has opposed third and fourth surfaces (142, 152). The third surface (142) is affixed to the lower surface (212) of the elastomeric core (200) and extends parallel to the first surface (42). The fourth surface (152) is inclined relative to the third surface (142). The second and fourth surfaces (52, 152) are inclined relative to each other.Type: GrantFiled: August 2, 2001Date of Patent: December 30, 2003Assignee: DePuy AcroMed, Inc.Inventors: Hassan Serhan, James Kuras, Carl McMillin, Maarten Persenaire
