An example device for detecting one or more parameters of a cardiac signal is disclosed herein. The device includes one or more electrodes and sensing circuitry configured to sense a cardiac signal via the one or more electrodes. The device further includes processing circuitry configured to determine an R-wave of the cardiac signal and determine whether the R-wave is noisy. Based on the R-wave being noisy, the processing circuitry is configured to determine whether the cardiac signal around a determined T-wave is noisy. Based on the cardiac signal around the determined T-wave not being noisy, the processing circuitry is configured to determine a QT interval or a corrected QT interval based on the determined T-wave and the determined R-wave.

Systems and techniques are disclosed to evaluate a neurostimulation treatment provided from a neurostimulation device, based on freeform text analysis. In an example, a system or device to evaluate a neurostimulation treatment provided from a neurostimulation device is configured to perform operations that: obtain text content, originating from text or voice input of a human patient, which relates to a state of a human patient; identify a state of the human patient from natural language processing of the text content; obtain device data from the neurostimulation device; identify a state of the neurostimulation treatment of the human patient from the device data; associate the identified state of the human patient to the identified state of the neurostimulation treatment; and initiate an action for the neurostimulation treatment, based on the identified state of the human patient that is associated with the identified state of the neurostimulation treatment.

A method for determining an intensity index for electrical stimulation includes receiving stimulation information; determining a stimulation field from the stimulation information; determining at least one stimulation field function using the stimulation field; and analyzing the determined at least one stimulation field function to determine the intensity index. The intensity index corresponds to a stimulation target and indexes at least one dosing reference for electrical stimulation for that stimulation target.

A stimulation probe device including a first electrode, a stimulation module, a control module and a physical layer module. The stimulation module is configured to (i) wirelessly receive a payload signal from a console interface module or a nerve integrity monitoring device, and (ii) supply a voltage or an amount of current to the first electrode to stimulate a nerve or a muscle in a patient. The control module is configured to generate a parameter signal indicating the voltage or the amount of current supplied to the electrode. The physical layer module is configured to (i) upconvert the parameter signal to a first radio frequency signal, and (ii) wirelessly transmit the first radio frequency signal from the stimulation probe to the console interface module or the nerve integrity monitoring device.

Various aspects of the present subject matter provide an implantable medical device. In various embodiments, the device comprises a pulse generator, a first monitor and a controller. The pulse generator is adapted to generate a neural stimulation signal for a neural stimulation therapy. The neural stimulation signal has at least one adjustable parameter. The first monitor is adapted to detect an undesired effect. In some embodiments, the undesired effect is myocardial infarction. The controller is adapted to respond to the first monitor and automatically adjust the at least one adjustable parameter of the neural stimulation signal to avoid the undesired effect of the neural stimulation therapy. Other aspects are provided herein.

An introducing device for locating a tissue region and deploying an electrode is shown and described. The introducing device may include an outer sheath. An inner sheath may be disposed within the outer sheath. The inner sheath may be configured to engage an implantable electrode. In an example, the inner sheath may comprise a stimulation probe having an uninsulated portion at or near a distal end of the delivery sheath. The outer sheath may be coupled to a power source or stimulation signal generating circuitry at a proximal end. A clinician may control application of the stimulation signal to a tissue region via the outer sheath.

Feedback regarding electrical stimulation is provided to a patient. Electrical stimulation is applied to the patient. The electrical stimulation is applied by varying an electrical stimulation parameter. A signal is communicated to the patient via an electronic device. The signal is correlated with the electrical stimulation parameter such that the signal varies in association with the varying of the electrical stimulation parameter. The communicating is performed while the electrical stimulation is applied. Feedback is received from the patient in response to the electrical stimulation. Based on the received feedback from the patient, the electrical stimulation is adjusted.

An implantable pacemaker has a first housing and a second housing tethered to the first housing by an elongated electrical conductor. The elongated electrical conductor has a proximal end coupled to the first housing and a distal end coupled to the second housing and includes a signal line configured to carry an electrical signal between the first housing and the second housing.

The present specification discloses devices and methodologies for the treatment of transient lower esophageal sphincter relaxations (tLESRs). Individuals with tLESRs may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow and have improved energy storage requirements.

Techniques are disclosed for determining, by an extracardiovascular implantable cardioverter defibrillator (ICD) implanted in a patient, whether one or more test therapy signals generated by another medical device implanted in the patient is detected. In response to detecting the one or more test therapy signals, the extracardiovascular ICD provides an indication that the extracardiovascular ICD has detected the one or more test therapy signals. In some examples, the indication is an audible tone provided to a clinician. In some examples, the other medical device is an intracardiac cardiac pacing device, and the one or more test therapy signals comprises a plurality of anti-tachycardia pacing (ATP) pulses.
