Insertion of medical devices through non-orthogonal and orthogonal trajectories within the cranium and methods of using
First Claim
1. A method of effecting or collecting data about a target site in a brain, the method comprising:
- creating an opening at an entry site in an outer surface of a patient'"'"'s skull, the skull having a thickness defined between the outer surface and an inner surface;
inserting a first shaft through the opening into the skull at the entry site along a first angle such that at least a portion of the first shaft extends within the skull between the outer and inner surfaces, the portion extending within the skull between the inner and outer surfaces diverging away from the opening of the outer surface as the first shaft extends from the outer surface to the inner surface, the first shaft having coupled thereto at least one component including an effector or a sensor, wherein the at least one component is inserted into the skull and extends inside the skull generally parallel to an inner surface of the skull, and extends between the skull and the brain; and
inserting a second shaft through the opening into the skull at the entry site along a second angle such that at least a portion of the second shaft extends within the skull between the outer and inner surfaces, the portion extending within the skull between the inner and outer surfaces diverging away from the opening of the outer surface as the second shaft extends from the outer surface to the inner surface, the second angle different from the first angle, the second shaft having coupled thereto at least one component including an effector or a sensor, wherein the at least one component is inserted into the skull and extends inside the skull generally parallel to the inner surface of the skull, and extends between the skull and the brain.

Abstract
An elongated device adapted for insertion, including self-insertion, through the body, especially the skull is disclosed. The device has at least one effector or sensor and is configured to permit implantation of multiple functional components through a single entry site into the skull by directing the components at different angles. The device may be used to provide electrical, magnetic, and other stimulation therapy to a patient'"'"'s brain. The lengths of the effectors, sensors, and other components may completely traverse skull thickness (at a diagonal angle) to barely protrude through to the brain'"'"'s cortex. The components may directly contact the brain'"'"'s cortex, but from there their signals can be directed to targets deeper within the brain. Effector lengths are directly proportional to their battery size and ability to store charge. Therefore, longer angled electrode effectors not limited by skull thickness permit longer-lasting batteries which expand treatment options.
