Implantable medical devices (IMD) such as those used in Deep Brain Stimulation application are commonly replaced when the device's useful life expires. At the time of replacement, the electrodes that were connected to the initial IMD are typically reused with the replacement IMD. It is desirable for the replacement IMD to utilize the stimulation parameters that were being utilized to provide stimulation in the initial IMD, but it is important that the electrodes be connected to the replacement IMD in a similar manner as they were connected to the initial IMD if stimulation parameters are reused. A connected electrode profile that includes measurements of electrical parameters associated with the electrodes can be generated in the initial IMD and the replacement IMD, and the profiles can be compared to determine whether the electrodes are connected in a similar manner in the replacement IMD as they were in the initial IMD.

Incorrect connection or mapping of leads' proximal terminals to the ports of an Implantable Stimulator Device (ISD), such as an implantable pulse generator or an external trial stimulator, is a concern, and this disclosure is directed to use of measurement and identification algorithms to either determine that leads are properly connected to their assigned ISD ports, or to determine which leads are connected to the ports even if the leads are not preassigned to the ports. Particular focus is given in the disclosed technique to assessing leads that comprise larger number of electrodes than are supported at each port, and thus have more than one proximal terminal that connect to more than one port of the ISD.

An electrode (10) for transcranial current stimulation is provided. The electrode (10) comprises at least two pins (11a, 11b) for contacting the skin of a living or human being, and a current delivering unit (12) connected to the at least two pins (11a, 11b). The current delivering unit (12) is configured to estimate the corresponding range of the respective contact impedance with respect to the skin for each of the at least two pins (11a, 11b) or to analyze the corresponding level of the respective contact impedance with respect to the skin for each of the at least two pins (11a, 11b). The current delivering unit (12) is configured to distribute a desired current over all of the at least two pins (11a, 11b) or to select a set of the at least two pins (11a, 11b) for delivering a set of partial currents in order to achieve the desired current.

In part the disclosure relates to methods of treating acne, excessive sweating, unwanted hair, and/or unwanted blood vessels. The method may include providing a needle array comprising a plurality of needles; inserting plurality of needles into a dermis of a treatment area; detecting a location of an enlarged sebaceous gland; and energizing one or more of the plurality of needles to treat sebaceous glands, one or more sweat glands, vascular legions, unwanted hair follicles and/or unwanted blood vessels.

Disclosed herein are various embodiments of an interface control subsystem that may be used between an electrode terminal and a recording terminal of a neurostimulation and neurorecording system. The interface control subsystem may operate in three modes. In a disable mode, a first transistor and a second transistor disposed between the electrode terminal and the recording terminal may operate in a cutoff region and generate a high impedance. In an active mode, the first transistor and the second transistor may operate in a saturation region and generate a low impedance. In a stimulation mode, the first transistor and the second transistor operate in a triode region and generate an impedance between the high impedance of the disable mode and the low impedance of the active mode. The interface control subsystem may further limit voltage at the recording terminal in response to a detected overvoltage condition.

Restless Leg Syndrome (RLS) or Periodic Limb Movement Disorder (PLMD) can be treated using high frequency (HF) electrostimulation. This can include selecting or receiving a subject presenting with RLS or PLMD. At least one electrostimulation electrode can be located at a location associated with at least one of, or at least one branch of, a sural nerve, a peroneal nerve, or a femoral nerve. HF electrostimulation can be delivered to the subject, which can include delivering subsensory, subthreshold, AC electrostimulation at a frequency that exceeds 500 Hz and is less than 15,000 Hz to the location to help reduce or alleviate the one or more symptoms associated with RLS or PLMD. A charge-balanced controlled-current HF electrostimulation waveform can be used.
