Abstract
A cranial lead fixation device includes a body configured for fixation to a cranium over or within a burr hole, and a fixation mechanism associated with the body. The body and fixation mechanism capture a medical device (e.g., a lead, catheter, or similar device) within a fixation channel of the cranial lead fixation device for protection of the burr hole and securement of the medical device. The cranial lead fixation device is operable for a first open configuration and a second closed configuration.
Claims17
A device, comprising:
- a body including:
- a burr hole aperture defining a central axis;
- a first portion of a fixation channel, the first portion of the fixation channel being in communication with the burr hole aperture;
- and
- an insertion channel in communication with the burr hole aperture for insertion of a medical device through the insertion channel and into the burr hole aperture;
- and
- a fixation mechanism pivotably coupled to the body by a connector mechanism defining a pivot axis that is substantially parallel to the central axis of the burr hole aperture, the fixation mechanism being rotatable about the pivot axis between a first open configuration and a second closed configuration, and the fixation mechanism having an inner face and a protrusion projecting from the inner face;
- wherein rotation of the fixation mechanism about the pivot axis from the first open configuration into the second closed configuration positions the protrusion within the insertion channel to occlude the insertion channel, completes the fixation channel, and occludes the burr hole aperture.

A method, comprising:
- a body defining an inner face, an outer face, and a burr hole aperture defining a central axis, the inner face being configured for engagement with a cranium of a patient;
- forming a first portion of a fixation channel along the outer face of the body and in communication with the burr hole aperture;
- forming an insertion channel in communication with the burr hole aperture for insertion of a medical device through the insertion channel and into the burr hole aperture;
- providing a fixation mechanism having an inner face;
- forming a first hinge aperture in the body and a second hinge aperture in the fixation mechanism, the first hinge aperture and the second hinge aperture being coaxially positionable to receive a pivot hinge of a connector mechanism that defines a pivot axis substantially parallel to the central axis of the burr hole aperture, such that, when the fixation mechanism is coupled to the body by the connector mechanism, the fixation mechanism is rotatable about the pivot axis between a first open configuration and a second closed configuration;
- and
- forming a protrusion projecting from the inner face of the fixation mechanism such that rotation of the fixation mechanism into the second closed configuration positions the protrusion within the insertion channel to occlude the insertion channel, completes the fixation channel, and occludes the burr hole aperture.
