Abstract: Implantable medical devices suitable for implantation in spaces between bones, such as in the spaces between vertebrae in a vertebral column of an animal, are described. An implantable medical device comprises a laminate structure in which a cover conforms to and is attached to a main body. The implantable medical device is suitable for implantation in spaces between bones, such as in the spaces between vertebrae in a vertebral column of an animal.

Abstract: The technical description relates to anchor assembly tools, drivers kits, and methods useful in connecting a structure with another structure. An anchor assembly tool includes an outer member having a distal end configured to engage a head member and an inner member having a distal end configured to engage an anchor. A driver includes an outer member, an inner member, and a grasping member. A set screw driver includes an outer member and an inner member. An example kit includes an anchor assembly tool, an anchor, and a head member. A method of assembling an anchor assembly tool comprises releasably attaching a head member to the distal end of the outer member, releasably attaching an anchor to the distal end of the inner member, and advancing the inner member within the outer member such that the anchor is disposed within the head member.

Abstract: A surgical guide is disclosed and methods of use are disclosed. The surgical guide is adapted to receive a surgeon's finger for dissecting to a target site. The surgical guide comprises a first component defining a channel and comprising a palpating portion and a non-palpating portion disposed on an opposing side from the palpating portion. The surgical guide further comprises a second component engaged with the first component and defining a guide channel extending therethrough. The guide channel is adapted to receive a guide pin suitable for insertion to the target site such that the guide pin is carried adjacent the non-palpating portion of the first component.

Abstract: An interbody spacer includes an elongated body with a maximum width between opposite side walls and a maximum height between upper and lower bearing surfaces. The interbody spacer also includes a leading end nose connecting the side walls to facilitate insertion of the interbody spacer into a disc space between vertebrae in an insertion orientation, from which the interbody device is then rotated to position the upper and lower bearing surfaces in contact with the endplates of the adjacent vertebrae. The leading end nose forms a blunt convex nose between the upper and lower bearing surfaces to maximize the bearing surface area available to contact the adjacent endplates.
