1. A method including:
- securing a base portion of a guide lumen carrying assembly around an entry portal in a surface;
rotating at least a portion of the guide lumen carrying assembly about a first axis that is substantially concentric to the entry portal and substantially orthogonal to the surface; and
tilting at least a portion of the assembly so that a second axis, extending concentrically through the guide lumen, is at a desired angle with the first axis.

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.

28. A method including:
-
securing a base access plate to a surface around an entry portal;
introducing an instrument through the entry portal to a target location beyond the surface; and
securing the introduced instrument to the base access plate.

-
37. A method including:
-
securing a base portion of a multiple primary guide lumen carrying assembly around an entry portal in a surface;
orienting a secondary guide lumen, with respect to a plurality of coupling locations of the primary guide lumen carrying assembly, such that the secondary guide lumen aligns with a desired one of the multiple primary guide lumens; and
coupling the secondary guide lumen to the primary guide lumen carrying assembly in the selected orientation.

42. A method including:
-
introducing a sheath through a portal in a surface to a target location;
introducing an instrument through the sheath to the target location;
rotating first and second portions of the sheath with respect to each other to create an access opening in the sheath above the surface of the portal, thereby exposing a portion of the instrument;
securing an exposed portion of the instrument; and
removing the sheath.
-
-
43. A method including:
-
securing a base portion of a guide lumen carrying assembly around an entry portal in a surface, the guide lumen providing a trajectory axis, and the body portal providing a portal normal axis that is orthogonal to the surface of the body portal;
adjusting an angle between the trajectory axis and the portal normal axis by pivoting an arcuate portion of the guide lumen carrying assembly with respect to the base; and
adjusting the angle between the trajectory axis and the portal normal axis by sliding a portion of the guide lumen carrying assembly along the arcuate portion of the guide lumen carrying assembly. - View Dependent Claims (44, 45, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64)
