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 of the burr cap assembly being configured to, while the implantable medical elongate member is secured by the burr cap assembly, 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:
inserting a portion of an implantable medical elongate member through an opening of a member of a burr cap assembly configured to be positioned at least partially within a burr hole in a cranium of a patient such that at least a portion of the implanted medical elongate member extends into a brain of the patient, wherein the member of the burr cap assembly is configured to be positioned within a cavity defined by the burr cap assembly and configured to, while the implantable medical elongate member is secured by the burr cap assembly, move within the cavity and in at least one dimension of a plane that is substantially perpendicular to a longitudinal axis of the at least the portion of the implantable medical elongate member, the member of the burr cap assembly being configured to enable movement of the at least a portion of the implantable medical elongate member in response to a force applied to the member of the burr cap assembly by the implantable medical elongate member following implantation of the at least the portion of the implantable medical 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 of the burr cap assembly being configured to, while the implantable medical elongate member is secured by the burr cap assembly, 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 the 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 defined by the member of the burr cap assembly, wherein the burr cap assembly comprises a cover configured to retain the implantable medical elongate member at a location in which 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)
