B23P 11/00

US Classification:

606278, 29428

Abstract:

In one embodiment, a medical device includes an elongate member, a first coupler, and a second coupler. The elongate member has a first end portion, a second end portion, and a side portion. The side portion of the elongate member has a first receiving portion and a second receiving portion. The first receiving portion is configured to receive a first support member. The second receiving portion is configured to receive a second support member. The first coupler is coupled to the elongate member and is configured to engage the first support member to help retain the first support member within the first receiving portion. The second coupler is coupled to the elongate member and is configured to engage the second support member to help retain the second support member within the second receiving portion.

International Classification:

A61F 2/44
A61F 2/46

Abstract:

An implant is insertable in the joint space to separate bones of the joint. The implant has two endplates each configured to engage a separate articulating bone of the joint, and a threaded member positioned between the two endplates and configured to increase the space between the two endplates when the threaded member is rotated. A rotatable gear is engaged with the threaded member, and is engageable with a rotating gear of a connected implantation tool, so that rotation of the gear on the tool causes rotation of the threaded member and expansion of the implant to separate the bones. Connector portions on the tool and the implant may be rotated together to securely engage the implant and the tool so that the gears of the tool and the implant can be rotated using an actuator outside of the body, when the implant is inside the body.

International Classification:

A61B 17/70

Abstract:

Devices and methods for coupling first and second adjacent vertebrae. The device includes a first coupling element and a second coupling element. The first coupling element has a first body portion for receiving a first bone fastener and an elongate rod portion extending transversely from the first body portion. The second coupling element has a second body portion for receiving a second bone fastener and an extension portion extending transversely from the second body portion. The extension portion defines a recess sized and configured to receive the rod portion of the first coupling element. When unlocked, the rod portion is moveable in the recess to allow for rotational and translational movement of the first and second coupling elements. When locked, the relative position of the first and second coupling elements is fixed.
