Abstract
An assembly for replacing a vertebral disc. The assembly includes an implant and a device for positioning the implant between two adjacent vertebrae. The implant includes a body having an internal compartment enclosed by an outer wall, and an endoskeleton coupled to the body. The device includes a cannula, a container coupled to the cannula, the container having a first end and a second end, a plunger threadingly coupled to the cannula and to the first end of the container, and a conduit coupled to the second end of the container and in fluid communication with the body of the implant. The implant is positioned within the cannula in an undeployed state and is deployed within a vertebral disc to receive a biological fluid in a second state.
Claims23
An assembly for replacing a vertebral disc, the assembly comprising:
- an implant including
- a body having an internal compartment enclosed by an outer wall;
- and
- an endoskeleton coupled to the body;
- a device including
- a cannula;
- a container coupled to the cannula, the container having a first end and a second end;
- a plunger threadingly coupled to the cannula and to the first end of the container;
- and
- a conduit coupled to the second end of the container and in fluid communication with the body of the implant,
- wherein the implant is positioned within the cannula in a first state and is deployed within a vertebral disc to receive a biological fluid in a second state.
A kit for inserting an implant replacing a nucleus pulposus, the kit comprising:
- a first assembly including
- a cannula having a first end and a second end, and
- a hub connected to the first end of the cannula;
- a second assembly including
- a container coupled to the cannula, the container having a first end and a second end,
- a plunger threadingly coupled to the first end of the cannula and to the first end of the container, and
- a conduit coupled to the second end of the container and in fluid communication with an implant.
A spinal implant comprising:
- a body including an internal compartment enclosed by an outer wall, the body positioned within a cannula in an undeployed state and the body configured to be filled with a biological fluid in a deployed state;
- and
- a nitinol endoskeleton configured to support the body, the endoskeleton being configured to constrain the body in an XY plane and to allow the body to expand along a plane perpendicular to the XY plane.
A method of implanting a spinal implant using an implantation device, the spinal implant including a body and an endoskeleton configured to support the body, the method comprising:
- coupling the implant to the implantation device;
- positioning the implant between adjacent spinal vertebrae;
- and
- transferring biological fluid from the implantation device to the implant thereby expanding the implant from a first, compressed state to a second, expanded state such that the implant replaces at least a portion of a nucleus pulposus of an intervertebral disc.
