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 power source to deliver a neural modulation signal;
a signal transmission system carried by the signal delivery system to transmit a locator signal;
an external signal detector system that is movable relative to the signal delivery device and positionable to detect the locator signal wirelessly through the patient'"'"'s skin, the signal detector system having at least one releasable fixation element positioned to releasably secure at least a portion of the signal detector system to the patient'"'"'s skin;
an insertion tracker positionable to track a length of the signal delivery system inserted into the patient; and
a computer-readable medium containing instructions that when executed;
compare a first inserted length of the signal delivery device based on information received from the external signal detector system and corresponding to a projected length of the signed deliver device in a plane of the external signal detector system, with a second inserted length of the signal delivery device based on information received from the insertion tracker; and
provide an indication when the first and second inserted lengths differ by at least a threshold amount.

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.
