Techniques for positioning therapy delivery elements within a spinal cord or brain

A method for providing treatment therapy to targeted tissue comprising the steps of:

• (a) implanting a therapy delivery device in a patient;
• (b) implanting a collar into bone of a patient, the collar having outer and inner threads the other threads used to secure the collar into the bone of the patient;
• (c) inserting a threaded housing into the collar, the threaded housing defining a proximal opening in a top portion of the housing, a passageway through the housing, and a distal opening;
• (d) implanting a lead in the patient through the proximal opening and passageway of the threaded housing so that a therapy delivery element of the implanted lead lies closer to the distal opening than the proximal opening;
• (e) coupling a proximal end of the lead to the implanted therapy delivery device;
• and (f) operating the implanted therapy delivery device to provide treatment therapy to the targeted tissue via the therapy delivery element.

A medical device for providing therapy to a body comprising:

• a plurality of leads, each lead having at least one therapy delivery element at a distal end of the lead;
• a plurality of collars, the plurality of collars having outer and inner threads, the plurality of collars configured to be screwed into bone of the body using the outer threads;
• a plurality of threaded housings configured such that at least a portion of the threaded housing is inserted into a channel defined by each of the plurality of collars, the plurality of threaded housings defining a proximal opening in a top portion of the threaded housings, a passageway through the threaded housings, and a distal opening, the proximal opening and passageway adapted to allow the therapy delivery element to be inserted therethrough and be positioned closer to the distal opening than the proximal opening;
• and
• a swivel mechanism connected to each of the plurality of threaded housings, the swivel mechanism configured to allow turning of the threaded inner housing without moving the plurality of leads.
