First Claim
Patent Images
1. A device for immobilizing a primary instrument, comprising:
- a base;
a stabilizer configured to engage the instrument, the stabilizer being configured to rest on the base and including at least one variable opening sized and shaped to at least partially surround the instrument and allow passage of the instrument when normally relaxed and to immobilize the instrument when compressed inwardly toward the instrument; and
a plate that is relatively more rigid than the stabilizer, the plate being configured to rest on the stabilizer and comprising a feature complementary to the normally relaxed size and shape of each variable opening of the stabilizer, yet shaped and sized to compress the at least one variable opening inwardly upon compression of the plate and the stabilizer together.

Abstract
Devices and methods provide accurate targeting, placement, and/or stabilization of an electrode or other instrument(s) into the brain or other body organ, such as to treat severe tremor or other neurological disorders. Targeting is performed using any form of image-guidance, including real-time MRI, CT, or frameless surgical navigation systems.

15. A device for immobilizing a primary instrument, comprising:
-
means for securing the device around an entry portal in a surface; and
means for varying an opening in the device to at least partially surround the instrument and allow passage of the instrument when the opening is normally relaxed and to immobilize the instrument when the opening is compressed inwardly toward the instrument. - View Dependent Claims (16, 17)
