    摘要： 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.

    摘要： Methods for automatically programming a signal generator in a patient therapy system and associated systems are disclosed. A representative method comprises retrieving data including therapy program parameters, level of efficacy, and medication use corresponding to a plurality of time periods; identifying from the data a target time period having a corresponding level of efficacy; determining from the data if medication was used during the target time period; determining from the data if medication was used during a prior time period immediately before the target time period; calculating a lead position confidence factor; and programming the signal generator to repeat therapy with the therapy program parameters corresponding to the target time period if the confidence factor is greater than a threshold value and medication was used during the prior time period and not during the target time period.

    摘要： Methods for identifying responders to paresthesia-free stimulation therapy, and associated systems are disclosed. A representative method comprises implanting a pair of spinal cord signal delivery devices and connecting an external signal generator thereto. A plurality of the electrical contacts are simultaneously activated with a high frequency signal without causing paresthesia in the patient, wherein the electrical contacts would cause paresthesia in the patient if activated with a low frequency signal. The high frequency signal is in a range of from about 3 kHz to about 20 kHz and an amplitude of less than 4 mA. If the patient responds favorably, a signal generator is implanted in the patient. A second high frequency signal is then applied to fewer than the plurality of electrical contacts.

    摘要： Methods for systematically testing a plurality of therapy programs in a spinal cord modulation system, and associated systems are disclosed. A representative method comprises loading a plurality of therapy programs into a signal generator, wherein individual therapy programs include parameters specifying electrode configuration, signal amplitude, and/or signal frequency. The programs are automatically activated for an automatically instructed period of time. The method includes automatically changing from one therapy program to another after the instructed period of time. The patient is queried for patient input corresponding to the therapy programs. The patient input is received via a remote. The patient input is correlated with a corresponding time of day and recorded in the signal generator. Thereafter, the patient input is retrieved from the signal generator.

    摘要： Couplings for implanted leads and external stimulators, and associated systems and methods are disclosed. A connector in accordance with a particular embodiment includes a first housing portion and a second housing portion pivotably connected to each other. The first housing portion has an elongated fixed stop opening. The second housing portion has a stop element and a plurality of connector contacts positioned to electrically contact a plurality of connection contacts of a spinal cord stimulation lead. The first and second housing portions are pivotably connected to each other to move between a partially-opened position in which the stop element is in a first location in the elongated fixed stop opening, and a closed position in which the stop element has a second location in the elongated fixed stop opening.
