The invention relates to a stimulation device for electrotherapy, in particular a defibrillator device and/or external pacemaker device, comprising: at least two contact electrodes (11, 12), which can be applied to the body of a patient at suitable stimulation positions and by means of which current pulses can be applied to the body of the patient (10), the first of the at least two contact electrodes (11, 12) acting as a supply electrode (12) having positive polarity, and the second of the at least two contact electrodes (11, 12) acting as a removal electrode (11) having negative polarity with respect to an emitted current pulse; and a current pulse generator (14), which is or can be connected to the contact electrodes (11, 12) by means of line connections (21, 17). In order to simplify the correct positioning of the contact electrodes on the body of the patient, a signal evaluation unit (15), which is or can be connected to the contact electrodes (11, 12), is provided for determining the application positions of the contact electrodes (11, 12) on the body of the patient (10), by means of which signal evaluation unit the polarity of the electrodes can also be automatically reversed in a preferred embodiment.

The disclosure describes an enhancement to lead monitoring techniques, which uses a sensing integrity counter (SIC). The techniques of this disclosure may enhance lead monitoring techniques by detecting possible sensing issues based on a significant increase in periodic, e.g., daily, SIC counts relative to previous periods. Some issues with sensing cardiac signals via implantable cardiac leads can result in an implantable medical device (IMD) measuring very short intervals between what appears to be sensed heart beats. Examples of issues include insulation breach, conductor fracture, or poor electrical connection, which may cause noise that appears to be an R-wave. The IMD may detect the noise, along with actual R-waves, and determine that there are relatively short (e.g., less than a threshold) intervals between the “R-waves.” A significant increase in the number or frequency of very short intervals between R-waves may indicate the date/time of a significant sensing issue.

This disclosure is directed to devices, systems, and techniques for controlling electrical stimulation. In some examples, a system includes a user interface and processing circuitry. The processing circuitry is configured to output, for display by the user interface, a message requesting the patient perform a set of actions, receive, from the user interface, user input indicative of a patient response associated with the set of actions, and determine, based on the user input, one or more adjustments to a control policy which controls electrical stimulation delivered by a medical device based on a plurality of evoked compound action potentials (ECAPs) sensed by the medical device.

An electrode unit for performing electroporation of a biological cell is provided, including at least one electrode which can contact a cell. A stimulation unit and an impedance measurement device are connected to the cell, respectively to provide signals to provide cell electroporation and to measure the impedance of the electrode in contact with the cell. Further, a memory stores a predetermined value of an impedance parameter of the biological cell, and it is arranged to be readable by a comparing element. The comparing element is configured to compare the value stored in the memory with a value measured with the impedance measurement device, and to produce an adjustment signal to the stimulation unit, forming a feedback loop. The unit is further configured to apply a further electrical signal for providing electroporation of the cell upon receiving the adjustment signal from the comparing element.

The test fixture may comprise a substrate (22), at least one electrically conductive pad (24a) disposed on the substrate for reducing pressure applied to the at least one electrode when the electrically conductive pad makes contact with an exposed surface of the electrode, and a wire (26a) extending from the at least one electrically conductive pad. The pad may be formed of a non-abrasive material, such as conductive foam or smooth metal. The substrate may be a probe formed with a number of slots for holding pads and routing wires, a mandrel with openings for holding pads and routing wires, and a flexible circuit with exposed smooth metal surfaces. The test fixture may be suitable for testing cuff-like and paddle-like devices.

A wearable, percutaneous device for suppressing appetite or hunger in a patient includes a microprocessor, electrical stimulator and at least one percutaneous electrode implanted and configured to deliver electrical stimulation through the patient's skin. The percutaneous device includes a pad and at least one needle, in which the electrode is disposed, for secure placement of the device within the skin of a patient. The percutaneous device is adapted to provide electrical stimulation as per stimulation protocols and to communicate wirelessly with a companion control device configured to monitor and record appetite patterns of the patient. The control device is also configured to monitor, record, and modify stimulation parameters of the stimulation protocols.

A patch for a therapeutic electrical stimulation device includes a shoe connected to the first side of the patch, the shoe including a body extending in a longitudinal direction from a first end to a second end, and having first and second surfaces, the first end of the shoe defining at least two ports, and the first surface of the shoe defining a connection member. The patch also includes at least one conductor positioned in the ports of the first end of the shoe. The shoe is configured for sliding insertion into a receptacle defined by a controller so that the conductor is connected to the controller to deliver electrical current from the controller, through the conductor, and to the electrodes, and the connection member is at least partially captured by a detent defined by the controller in the receptacle to retain the shoe within the receptacle.

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.

The present invention provides an apparatus and method for limiting the power output of a transcutaneous electrical stimulator in response to changes in electrode impedance.
