  • Publication number: 20140025107
    Abstract: A deployment device for a tissue repair system includes a front delivery assembly that is detachable from a base assembly of the deployment device. The front delivery assembly includes at least one prosthesis and at least one driven assembly that actuates the at least one prosthesis. The base assembly includes a driving assembly that may engage the at least one driven assembly of the at least one prosthesis. The front delivery assembly can be rotated so that the position of a prosthesis in the front delivery assembly is moved in and out of alignment with the driving assembly. A kit of parts may be provided that includes a base assembly as well as two or more detachable front delivery assemblies.

  • Patent number: 8603118
    Abstract: A tissue repair system is disclosed. The tissue repair system can include a prosthesis with a first end portion, a second end portion and an intermediate portion disposed therebetween. The first end portion can engage the second end portion when installed to retain tissue in a desired configuration. The tissue repair system can also include a delivery device configured to implant and fasten the prosthesis to repair imperfections in tissue or retain tissue in a desired configuration. The delivery device may be configured to fasten the first end portion and second end portion of the prosthesis on a distal portion of the tissue.

  • Publication number: 20130282063
    Abstract: A dynamic stabilization device is disclosed. The device includes a dual spring member comprising an outer spring and an inner spring that have approximately equal working lengths. The dynamic stabilization device is also configured so that the dual spring member does not undergo stresses greater than an effective fatigue limit that is related to a fatigue limit of the spring. Methods for treating a deformity of a spine using a dynamic stabilization device are also disclosed.

  • Patent number: 8518117
    Abstract: 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 configured for insertion between two adjacent vertebrae, the implant strip including a first portion having a first rigidity and a second portion having a second rigidity that is less than the first rigidity, wherein the second portion is configured to deflect under an axial load before the first portion deflects.

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.

  • Patent number: 8317868
    Abstract: A repair system including a closure prosthesis and deployment device, and associated methods for repairing any imperfection including a flaw, hole, tear, bulge, or, in some cases, a deliberate cut or incision in any tissue including an intervertebral disc. The prosthesis has first and second side portions with a connecting central portion, and is designed to span an imperfection with opposite ends positioned on opposite sides of the imperfection. The prosthesis may include anchoring features including barbs and/or members that extend transversely. The deployment device can include a cannula for positioning the prosthesis near the imperfection, and, in some cases, a mechanism that may cause the two sides of the prosthesis to be deployed in a specific order.
