Cam lock burr hole plug for securing retainer/plug base
First Claim
1. A cranial burr hole plug, comprising:
- a plug base configured for being mounted around a cranial burr hole, the plug base including an aperture through which an elongated medical device exiting the burr hole may pass; and
a retainer configured for being mounted within the aperture of the plug base, the retainer including a retainer support, a slot formed in the retainer support for receiving the medical device, and a clamping mechanism having a movable clamping element and a cam configured for being rotated relative to the retainer support to linearly translate the movable clamping element towards the plug base, thereby laterally securing the retainer within the plug base.

Abstract
A burr hole plug comprises a plug base configured for being mounted around a cranial burr hole. The plug base includes an aperture through which an elongated medical device exiting the burr hole may pass. The burr hole plug further comprises a retainer configured for being mounted within the aperture of the plug base. The retainer includes a retainer support, a slot formed in the retainer support for receiving the medical device, and a clamping mechanism having a movable clamping element and a cam configured for being rotated relative to the retainer support to linearly translate the movable clamping element into the slot, thereby securing the medical device. The retainer further comprises another clamping mechanism having another movable clamping element and another cam configured for being rotated relative to the retainer support to linearly translate the other movable clamping element, thereby laterally securing the retainer within the plug base.
