Publication number: 20140025082Abstract: A deployment device for a prosthesis includes a driving assembly, including a driving tube and a driving pin. The deployment device also includes a driven assembly, including a driven tube and a driven pin. The driven pin and the driven tube may be further associated with the prosthesis. The driving tube, the driving pin, the driven tube and the driven pin may all be located coaxially, with the driving pin configured to translate through a cavity in the driving tube and the driven pin configured to translate through a cavity in the driven tube. This configuration allows for a two-stage implantation process for the prosthesis, as the driving tube and driving pin may move together in one stage and may move relative to one another in a second stage.Type: ApplicationFiled: July 18, 2012Publication date: January 23, 2014Applicant: JMEA CORPORATIONInventors: James A.

Patent number: 8518118Abstract: An embodiment provides an implant prosthesis. In some cases, the prosthesis can take the form of an implant strip that may be implanted through the use of a surgical procedure that minimizes incision sizes and may be considered less invasive than typical spinal implant procedures. In one aspect, a spinal prosthesis may include an implant strip including a first portion comprising a first lateral side portion and a second lateral side portion, and a second portion separating the first lateral side portion from the second lateral side portion, with the first and second lateral side portions configured to engage a first and second vertebra, with a first longitudinal portion of the implant strip forming a first inner coil, with a second longitudinal portion forming a second outer coil, and with the second outer coil spaced radially outward of the first inner coil, wherein the second portion deflects before the first portion under compressive and tensile forces.Type: GrantFiled: February 27, 2008Date of Patent: August 27, 2013Assignee: JMEA CorporationInventors: James A.
