    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.

    Abstract: Systems and methods for detecting intrathecal penetration are disclosed. A method in accordance with one embodiment includes detecting a value corresponding to an impedance of an electrical circuit that in turn includes an electrical contact located within the patient, and patient tissue adjacent to the electrical contact. The method further includes comparing the detected value to a predetermined criterion, and, if the detected value meets the predetermined criterion, identifying penetration of the patient's dura based at least in part on the detected value.

    Abstract: An implantable lead having at least one electrode contact at or near its distal end prevents undesirable movement of the electrode contact from its initial implant location. One embodiment relates to a spinal cord stimulation (SCS) lead. A first injectable material is injected into the dura space to mechanically position the electrode array with respect to the spinal cord. Conjunctively for use with adhesives, or alternatively for use instead of the adhesives, a balloon may be positioned on the electrode lead array. The balloon is filled with air, liquid or a compliant material. When inflated, the balloon stabilizes the lead with respect to the spinal cord and holds the lead in place. An elastic aspect of the balloon serves as an internal contained relief valve to limit the pressure the balloon may place on the surrounding tissues when the epidural space is constrained.

    Abstract: A method for transitioning electrical energy in steps between electrodes implanted within a patient to stimulate tissue (e.g., spinal cord tissue) is provided. The method comprises determining a maximum comfortable step size, determining a minimum step size, selecting one or more step sizes between the maximum comfortable step size and the minimize step size, and transitioning the electrical energy between the electrodes using the selected one or more step sizes.

    Abstract: A method for determining whether the relative position of electrodes used by a neurostimulation system has changed within a patient comprises determining the amplitude of a field potential at each of at least one of the electrodes, determining if a change in each of the determined electric field amplitudes has occurred, and analyzing the change in each of the determined electric field amplitudes to determine whether a change in the relative position of the electrodes has occurred. Another method comprises measuring a first monopolar impedance between a first electrode and a reference electrode, measuring a second monopolar impedance between second electrode and the reference electrode, measuring a bipolar impedance between the first and second electrodes, and estimating an amplitude of a field potential at the second electrode based on the first and second monopolar impedances and the bipolar impedance.

    Abstract: A tissue stimulation system is provided that evaluates and/or scores stimulation sets based on both patient feedback and frequency of use. Stimulation sets and any associated scores and/or usage may be stored in a retrievable database. Upon subsequent stimulation sessions, a patient may select stimulation sets that have a high score and/or usage in order to effectively meet therapeutic objectives. Methods of determining patient satisfaction, which involve evaluating patient pain before and after stimulation pulses are applied, are also provided herein.
