ElectroCorticoGraphy (ECoG) sensors and uses are disclosed. These ECoG arrays, systems, and processes may be operable or configured to: i) simultaneously record neural signals while providing stimulation on specific portions of the cortex using a user-guided stimulator; ii) acquire neural signals over a large cortex area; iii) provide individual or group stimulation while concurrently receiving neural feedback; and/or iv) acquire neural signals at a setting remote from the neural source using wireless or other communication techniques.

An implantable medical device is disclosed. A housing includes a hollow body forming a first electrode on an outer surface with end caps affixed to opposite ends, one end cap forming a second electrode. A microcontroller circuit is provided and includes a microcontroller operable under program instructions stored within a non-volatile memory device. An analog front end is interfaced to the electrodes to sense electrocardiographic signals. A transceiver circuit is operable to wirelessly communicate with an external data device. The program instructions define instructions to continuously sample the electrocardiographic signals into the non-volatile memory device and to offload the non-volatile memory device to the external data device. A receiving coil and a charging circuit are operable to charge an onboard power source for the microcontroller circuit.

A system for interfacing an in-body medical device with an external network includes a subdermal wideband on-body network (WON) hub, which in turn includes a hub rechargeable battery, a hub processor coupled to the hub rechargeable battery, a device interface configured to communicate with the in-body medical device, and coupled to the hub processor, and a hub-satellite near field communications wireless interface coupled to the hub processor. The system also includes a wearable WON server that in turn includes a server processor, a server-satellite interface coupled to the server processor, and an external network interface coupled to the server processor. The server processor implements a software controller; and a skin-mountable WON tethered satellite that includes a wired satellite-server interface, coupled to the wearable WON server, and a tethered satellite near-field communications (NFC) wireless interface, configured to communicate with the hub-satellite NFC wireless interface, and coupled to the wired satellite-server interface.

An apparatus that includes a partial power source including a first material and a second material, the partial power source configured to generate, upon contact with a conducting medium, a potential difference between the first material and the second material to provide power to a control device, and generate, using the first material and the second material, a current flow within the conducting medium, the current flow including information encoded based on a variable conductance between the first material and the second material.

A prosthesis for monitoring a characteristic of flow includes a first tubular prosthesis having a lumen and a sensor for detecting the characteristic of flow through the lumen. The sensor may be covered with another tubular prosthesis or by a layer of material in order to insulate the sensor from the fluid flow. A pocket may be formed between the tubular prosthesis and the adjacent layer of material or prosthesis and the sensor may be disposed in the pocket.

An active implantable medical device (IMD) which, in operation: repeatedly senses a body temperature of a person having the IMD implanted therein; stores the sensed body temperature values; repeatedly senses a cardiac physiologic parameter of the person; stores the sensed cardiac physiologic parameter values; determines whether one of the body temperature values exceeds a predefined body temperature threshold; if an excess is determined, the IMD: determines whether one of the cardiac physiologic parameter values exceeds a predefined cardiac physiologic parameter threshold, wherein the one cardiac physiologic parameter value is determined in the same time period as the one body temperature value exceeding the body temperature threshold; classifies an infection of the person as a local infection if the one cardiac physiologic parameter value does not exceed the threshold; or classifies an infection of the person as a systemic infection if the one cardiac physiologic parameter value exceeds the threshold.

Systems and methods describe providing for the intelligent assessment and analysis of medical patient data. In one embodiment, the system receives medical imaging data of a patient, as well as connected implant data from an implant device implanted in the patient. A number of features are extracted via artificial intelligence (AI) algorithms from the medical imaging data and connected implant data. One or more reports are then generated based on the extracted features. In some embodiments, the systems and methods provide for indices, features, information, and/or metrics which have clinical value, and which enable a surgeon to support his or her decisions (related to, e.g., diagnosis, prognosis, monitoring, or any other suitable subject area).

Systems and methods for determining monitoring compliance are provided. Each element in a plurality of data elements is obtained from a medical device connected to a corresponding subject in a first plurality of subjects and interrogated to determine a condition of the device or subject. A medical code and timestamp for evaluation of the device or subject is recorded in the subject's medical record. A determination is made for each epoch in a plurality of epochs, for each subject in a second plurality of subjects, whether the medical code is recorded in the subject's medical record for the epoch by evaluating the time stamps and codes in the medical records. A compliance counter is advanced when a medical record includes the code for a respective epoch and otherwise a noncompliance counter is advanced. Responsive to a compliance request, compliance information or suggested treatment options are provided based on the counters.

Described herein are systems, devices, and methods for energy-efficient operation of wireless devices. In some variations, a wireless monitor may comprise a sensor configured to measure a physiological parameter of a patient at a first resolution. A processor may be configured to generate physiological parameter data based on the measured physiological parameter of the patient at the first resolution. The sensor may be configured to measure the physiological parameter of the patient at a second resolution based at least in part on the physiological parameter data.

Systems and methods involving implants positioned within implant pockets through minimally invasive entrance incisions, along with related implants. In some implementations, implants may be folded, rolled, or otherwise compressed to fit within subcutaneous implant pockets, after which they may be decompressed to fit within an implant pocket having one or more dimensions substantially larger than the entrance incision. Such implants may be used for a variety of purposes, including generating electrical energy for various other implants located throughout the body.
