SHIFTING BURR CAP ASSEMBLY
First Claim
1. An implantable medical device comprising:
- a burr cap assembly configured to be positioned at least partially within a burr hole in a cranium of a patient, the burr cap assembly defining a cavity and being configured to enable implantation of at least a portion of an implantable medical elongate member into a brain of the patient through the burr cap assembly, the burr cap assembly including a member positioned within the cavity of the burr cap and defining at least one opening to enable passage of at least a portion of the implantable medical elongate member into the brain of the patient, the member being configured to move within the cavity relative to the burr cap within at least one dimension of a plane that is substantially perpendicular to a longitudinal axis of at least a portion of the implantable medical elongate member.

Abstract
A burr cap assembly is at least partially inserted into a burr hole within the cranium of a patient. The burr cap assembly enables a elongate member to be inserted through the burr cap assembly to access a brain of the patient. A shifting member of the burr cap assembly may be configured to enable the elongate member to move with shifting fluid and matter of the brain. The shifting member of the burr cap assembly may be configured to move within a cavity defined by the burr cap assembly. The shifting member may be configured to move in a direction that is substantially perpendicular to a longitudinal axis of the distal portion of the elongate member. The shifting member may at least partially retain the elongate member, so as the shifting brain applies forces upon the elongate member, the elongate member and the shifting member may move within the cavity.

13. A method comprising:
in a burr cap assembly positioned at least partially within a burr hole in a cranium of a patient, moving a member, through which at least a portion of an implanted medical elongate member extends into a brain of the patient, within a cavity defined by the burr cap assembly, in at least one dimension of a plane that is substantially perpendicular to a longitudinal axis of the at least a portion of the implantable medical elongate member, to move the at least a portion of the implantable medical elongate member in response to a force applied to the member by the implantable medical elongate member following implantation of the at least a portion of the implantable elongate member in the brain of the patient. - View Dependent Claims (14, 15, 16)

17. An implantable medical device comprising:
-
a burr cap assembly configured to be positioned at least partially within a burr hole in a cranium of a patient, the burr cap assembly defining a cavity, the burr cap assembly including a member positioned within the cavity of the burr cap assembly and defining at least one opening, the member being configured to move within the cavity relative to the burr cap assembly within at least one dimension of a plane that is substantially perpendicular to a longitudinal axis of at least a portion of the implantable medical elongate member; and an implantable medical elongate member, wherein at least a portion of the implantable medical elongate member is configured to be implanted into a brain of the patient through both the burr cap assembly and the at least one opening of the member, wherein the burr cap assembly comprises a cover configured to retain the implantable medical elongate member as the implantable medical elongate member enters the burr cap assembly, the cover configured to substantially seal the burr cap. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
