Cranial Anchoring and Positioning System and Method
First Claim
1. A cranial anchor system configured to attach to an opening in a cranium, the system comprising:
- an anchor member that is elongate along a first axis, the anchor member including;
a middle anchor portion defining a middle anchor recess that extends about the first axis; and
a lower anchor portion coupled to and disposed in a downward direction relative to the middle anchor portion along the first axis, the lower anchor portion including;
a plurality of contact members that together define a lower anchor recess, each of the plurality of contact members having;
a leg that extends at least partially in the downward direction,a tab connected to the leg, the tab extending at least partially in a radial direction, the radial direction being perpendicular to the first axis, anda rib disposed between the leg and the tab;
an outer sheath that is elongate along a second axis and defines a first channel, the outer sheath including a lower outer sheath portion configured to be at least partially disposed within the middle anchor recess and the lower anchor recess such that the lower outer sheath portion is rotatable within the middle anchor recess and the lower anchor recess; and
an inner sheath disposed within the first channel and slidable relative to the outer sheath along the second axis, the inner sheath defining a second channel that is elongate along the second axis.

Abstract
A cranial anchor system configured to attach to an opening in a cranium includes an anchor member. The anchor member has a middle anchor portion and a lower anchor portion coupled to and disposed in a downward direction relative to the middle anchor portion. The lower anchor portion has a plurality of contact members, each of which have a leg that extends at least partially in the downward direction, a tab connected to the leg, and a rib disposed between the leg and the tab. The system further includes an outer sheath and an inner sheath disposed within the outer sheath and slidable relative to the outer sheath.
