Intracranial bolt and method of placing and using an intracranial bolt to position a medical device
First Claim
1. A clamp for releasably anchoring a medical device extending through an opening in a skull, the clamp comprising:
- a body adapted to be secured in the opening in the skull, the body having a bore therethrough for the passage of a medical device, and an inflatable member, positioned in the bore, which when inflated can engage a medical device passing through bore, to releasably anchor the medical device.

Abstract
An intracranial bolt, for installation in an opening in the skull to provide access to the brain for a medical device, has a bore therethrough for the passage of the medical device, and an inflatable member in the bore which when inflated engages a medical device in the bore, releasably anchoring the device. The inflatable member comprises a cylinder of flexible sheet material inside the bore and secured to the wall of the bore defining an annular pocket therebetween. A passage extends through the bolt to the pocket for the introduction of fluid into the pocket to expanding radially inwardly. The bolt in a medical procedure on the brain by forming an opening in the skull; installing the intracranial bolt in the opening in the skull; and securing the cap on the bolt. When it is time to conduct the procedure, the cap is removed and a medical device can be inserted into the brain through the bolt. The inflatable member can be inflated to temporarily hold the medical device in place.

7. A clamp for releasably anchoring a medical device extending through an opening in a skull, the clamp comprising:
a body adapted to be secured in the opening in the skull, the body having a bore therethrough for the passage of a medical device;
a panel of flexible sheet material secured to a wall of the bore to form a pocket between the panel and the wall, and a passage through the body communicating with the pocket;
the panel expanding radially inwardly into the bore upon the introduction of fluid into the pocket to engage a medical device passing through the bore to releasably anchor the medical device.- View Dependent Claims (8, 9)

An intracranial bolt for installation in an opening in a skull to provide access to a brain for a medical device, the bolt having a bore therethrough for the passage of a medical device, and an inflatable member, in the bore, which when inflated can engage a medical device passing through the bore, to releasably anchor the medical device.
- 18. An intracranial bolt for installation in an opening in a skull to provide access to a brain for a medical device, the bolt having a distal portion adapted to be secured in the opening of the skull, and a proximal portion adapted to project from the skull when the bolt is installed in the opening, and a bore extending between the proximal and distal sections, the proximal portion adapted to sealingly receive a cap for closing the proximal end of the bore.

23. A method of performing a medical procedure on the brain comprising:
-
forming an opening in the skull; installing an intracranial bolt in the opening in the skull, the intracranial bolt having a distal portion adapted to be secured in the opening in the skull, a proximal portion adapted to project from the skull when the bolt is installed in the opening, and a bore extending between the proximal and distal sections for providing access to the brain through the bolt; securing a cap on the proximal end of the bolt; and removing the cap after installation of the bolt and inserting a medical device through the bore in the bolt to perform a medical procedure on the brain. - View Dependent Claims (24)
