Systems and methods for positioning implanted devices in a patient
First Claim
1. A patient treatment system, comprising:
- a signal delivery system that includes a patient-implantable signal delivery device coupleable to a signal generator to deliver a neural modulation signal;
a signal transmission system carried by the signal delivery system to transmit a locator signal; and
an array of external signal detector elements and display elements that is movable relative to the signal delivery device, the external signal detector elements being positionable to detect the locator signal wirelessly through the patient'"'"'s skin, the display elements being operatively coupled to the signal detector elements to display data based on information provided by the detector elements, wherein the array defines a plane, and wherein individual detector elements and corresponding individual display elements are co-located to have the same coordinates in the plane.

Abstract
Systems and methods for positioning implanted devices in a patient are disclosed. A method in accordance with a particular embodiment includes, for each of a plurality of patients, receiving a target location from which to deliver a modulation signal to the patient'"'"'s spinal cord. The method further includes implanting a signal delivery device within a vertebral foramen of each patient, and positioning an electrical contact carried by the signal delivery device to be within ±5 mm. of the target location, without the use of fluoroscopy. The method can still further include, for each of the plurality of patients, activating the electrical contact to modulate neural activity at the spinal cord. In further particular embodiments, RF signals, ultrasound, magnetic fields, and/or other techniques are used to locate the signal delivery device.
