Abstract

A burr hole cover is configured to be recessed in a burr hole formed in a patient and includes a base and a cap provided with complementary features to allow a portion of a medical device, such as a brain lead, to be situated in the burr hole cover and then secured by rotation of the cap relative to the base. The features include channels on the base and matching cut-outs on the cap, and slots and locking pockets on the base that are configured to be aligned with locking tabs and locking protrusions on the cap. Because the burr hole cover is recessed in the burr hole, the medical device can extend proximally of the burr hole at the level of the cranium. A bottom surface of the cap may be provided with guides for the lead extending distally in towards the brain.

Dependent claims

A burr hole cover for securing a portion of a medical device within a burr hole formed in a patient's cranium, the burr hole cover comprising:

a base provided with a cap-receiving aperture, a plurality of base channels, and at least one slot having a locking pocket provided in the at least one slot of the base;
and
a cap provided with a corresponding cut-out for each channel of the plurality of base channels provided in the base, and a locking protrusion dimensioned to fit within the at least one slot of the base,
wherein the cap is configured to be placed in the cap-receiving aperture and to transition, through rotational movement of the cap relative to the base, between 1) an unlocked position during which the locking protrusion is vertically aligned with an axis of the at least one slot and the locking protrusion is disengaged from the locking pocket of the at least one slot of the base, and 2) a locked position during which the locking protrusion is offset from the axis of the at least one slot and the locking protrusion is engaged with the locking pocket of the at least one slot of the base.
