Abstract: Various embodiments of a placement tool for an apparatus to be fastened to a cranium with a fastener around a burr hole formed through the cranium are disclosed. The placement tool includes a receptacle adapted to hold the fastener, where the receptacle includes a channel extending between an upper opening of the receptacle and a lower opening of the receptacle along a channel axis. The placement tool further includes a retainer disposed within the channel of the receptacle, where the retainer includes a recess or a protrusion adapted to restrain the fastener against movement. The fastener opening of the apparatus is configured to align with the channel axis of the channel of the receptacle when the placement tool is engaged with the apparatus.

Abstract: An apparatus for fastening around a cranial burr hole includes a substantially flat core and a shell encapsulating a ring portion of the core. The shell defines an orifice substantially centered within the ring portion, and has a contoured lower surface to match the cranial curvature. Pliable arms of the core extend laterally from the ring portion, each being terminated by a fastener member. A central portion of a placement tool for the apparatus has a lower part configured to extend through the apparatus orifice, and an upper part from which first and second arms of the tool extend laterally. Each tool arm is terminated with a receptacle to hold a bone screw, and, when the tool central portion lower part extends through the apparatus orifice, each receptacle aligns with a corresponding fastener member, and lower openings of the receptacles are generally oriented along the contoured lower surface.
