Abstract
The present invention is a method and apparatus for securing an implantable lead within a brain of a patient comprising a bur ring and a septum contained within an aperture of the bur ring. The burr ring may be secured to a skull portion of the brain and the septum accepts and secures the lead in a substantially fixed position relative to the brain. The septum may be composed of a silicone rubber, elastomer, polyurethane, or butyl rubber. The septum may have a sold composition, a porous composition, or one have at least one blind hole for accepting the lead. The burr ring may include a one or more guides positioned along an upper flange portion of the burr ring accepting the lead and a cap capable of being positioned to close the aperture of the burr ring.
Claims24
A device for securing an implantable lead within a brain of a patient comprising:
- (a) a burr ring capable of being secured to a skull portion of the brain and having an aperture;
- and
- (b) a septum contained within the aperture of the burr ring capable of accepting the lead at a plurality of locations along a surface of the septum and of securing the lead in a substantially fixed position relative to the brain.
A method of securing an implantable lead having a distal end and a proximal end such that the distal end is positioned near a predetermined portion of a brain of a patient comprising the steps of:
- (a) securing a burr ring to a skull portion of the patient, the burr ring having an aperture and a septum contained within the aperture;
- (b) inserting the lead into the septum from amongst a plurality of locations along a surface of the septum in the direction of the predetermined portion of the brain;
- and
- (c) forwarding the lead into the brain through the septum until the distal end of the lead is positioned near the predetermined portion of the brain.
A device for securing an implantable lead within a brain of a patient comprising:
- (a) a burr ring capable of being secured to a skull portion of the brain and having an aperture;
- and
- (b) a septum contained within the aperture of the burr ring capable of accepting and securing the lead in a substantially fixed position relative to the brain and of projecting the lead along one of a possible plurality of trajectories into the brain.
A method of securing an implantable lead having a distal end and a proximal end such that the distal end is positioned near a predetermined portion of a brain of a patient comprising the steps of:
- (a) securing a burr ring to a skull portion of the patient, the burr ring having an aperture and a septum contained within the aperture;
- (b) inserting the lead into the septum in the direction of the predetermined portion of the brain, the septum capable of directing the lead along one of a possible plurality of trajectories into the brain;
- and
- (c) forwarding the lead into the brain through the septum until the distal end of the lead is positioned near the predetermined portion of the brain.
