Abstract: A rongeur including a base, which includes a handle portion, a body portion and a shaft portion. The shaft portion is made of a metal material and includes a male mold-on interlock portion configured to non-removably interlock with an over-molded plastic material. The body portion is made of plastic material and includes an over-mold interlock portion that is over-molded onto and non-removably fixed onto the mold-on interlock portion of the shaft portion. A slide shaft of the rongeur includes a distal portion and a proximal portion. The distal portion is made of a metal material and includes a male mold-on interlock portion configured to non-removably interlock with an over-molded plastic material. The proximal portion is made of a plastic material and includes an over-mold interlock portion that is over-molded onto and non-removably fixed onto the mold-on interlock portion of the distal portion.

Abstract: An interspinous process spacer device that is operable to be positioned between the spinous process of adjacent vertebra. The spacer device includes a body portion having a central bore extending therethrough, where the body portion includes a cylindrical center portion, a tapered front-end portion and a threaded portion, and where the center portion includes circumferentially disposed channels for delivering bone graft material. The spacer device also includes a spacer ring having an outer rim with a larger diameter than the center portion and a threaded opening that allows the spacer ring to be threaded onto the threaded portion. The spacer device further includes a securing member positioned against the spacer ring and including a threaded opening that allows the member to be threaded onto the threaded portion opposite to the center portion so that the spinous process can be locked between the front-end portion and the spacer ring.

Abstract: An example device for the fixation and support of bone bodies includes a base member for implantation into a patient at a location between two bone bodies. The base member of the device includes an enclosed chamber for receiving fusion material and apertures for receiving bone fasteners that can be embedded into the adjacent bone bodies. The device further includes protrusions extending from the base member, wherein the protrusions are configured for engagement with one or more bone bodes upon implantation and for progressive penetration into at least one bone body over a period of time subsequent to the implantation.

Abstract: An implant device for the spine suitable for the fixation and support of adjacent vertebrae includes a base member for implantation at a location between the two vertebrae and one or more protrusions extending from the base member. The protrusion(s) are configured for engagement with one of the vertebrae upon implantation and for progressive penetration into the vertebrae over a period of time subsequent to the implantation. The implant device includes a lateral mounting portion to accommodate fixation of the device to a lateral side of the vertebrae. The implant device is configured for insertion between the adjacent vertebrae through a posterior lateral or lateral opening that exposes a lateral side of the disc space.

Abstract: Kit and associated method with at least one tool for achieving selective implantation. The kit includes a fixation device for implant location intermediate the two bone bodies, a spacer for implant location intermediate the two bone bodies and adjacent the fixation device, and at least one implantation tool. The at least one tool has a portion for engaging and holding at least one of the device and the spacer during implantation of the at least one of the device and the spacer for implant location intermediate the two bone bodies and for releasing the held at least one of the device and the spacer subsequent to implantation. The at least one tool may be a single tool for engaging and holding both.

Abstract: An insertion tool has a curved fastener guide for allowing a user to safely insert bone fasteners and associated tools at the surgical site for securing an implant device to a bone body. The insertion tool has an elongate cannula and attachment shaft coupled to the distal end of the fastener guide. The attachment shaft can be docked to an implant device and the insertion tool can be used to locate the implant device at the surgical site. The fastener guide can be aligned with fastener holes in the implant device for accurate placement of the bone fasteners.
