First Claim
Patent Images
1. A method for creating an intracranial access point comprising:
- forming a hole in a skull;
inserting a threaded, hollow shaft through a lumen of at least one body;
engaging the threads of the hollow shaft with an interior surface of the hole in the skull by rotating the hollow shaft; and
rotating the hollow shaft until a proximal surface of the shaft pinches the body against a surface of the skull approximate the hole in the skull.

Abstract
A bolt stop for use with an intracranial access bolt that assists in preventing penetration of the bolt into the skull, resists accidental rotation and movement of the bolt with in the skull, and facilitates healing of the scalp.

8. A method for deploying an intracranial bolt comprising:
-
surrounding a portion of a threaded shaft of an intracranial bolt with a body having a length less than a length of the shaft; screwing the threaded shaft of the intracranial bolt into a hole in a skull; and resisting the screwing of the threaded shaft of the intracranial bolt into the hole in the skull with the body when the threaded shaft has engaged the hole in the skull a distance approximately equal to a difference in the length of the body and the length of the shaft. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for deploying an intracranial probe comprising:
-
engaging a threaded shaft of an intracranial bolt with a hole in a skull by rotating the intracranial bolt; preventing further rotation of the intracranial bolt when a distal end of the threaded shaft of the intracranial bolt is approximately planar with a interior surface of the skull; and deploying a probe into the skull through a lumen formed axially through the intracranial bolt. - View Dependent Claims (17, 18, 19, 20)
