The present disclosure provides implants, sensor modules, networks, and methods configured to establish transcutaneous power and transcutaneous bidirectional data communication using ultrasound signals between two or more medical devices located on and within a body of a patient.

A system that provides an independent and agnostic cardiovascular sensing ability that can be deployed prior to the standard treatment methods for blocked cardiovascular arteries, and placed in the zone of a vascular lesion for treatment, placing sensors that can monitor blood and vessel specificity to manage the acute and long term biologic reaction to the treatment zone communicating information for analytical management and decision processing to an external or internal receiving station.

The present disclosure provides implants, sensor modules, networks, and methods configured to establish transcutaneous power and transcutaneous bidirectional data communication using ultrasound signals between two or more medical devices located on and within a body of a patient.

This disclosure is directed to devices, systems, and techniques for an external device to receive data collected by an IMD implanted in a patient. The IMD may collect physiological data associated with a patient and store the physiological data in memory. The IMD may determine an amount of the physiological data stored in the memory to send to an external device and send, via a wireless connection, the determined amount of the physiological data stored in memory to the external device.

An insertable cardiac monitor (ICM) with induction-based recharging capabilities and a transmitting coil for recharging the same are disclosed. The length of the monitoring performed by the ICM is extended and the functionality of the ICM enhanced, by including an internal energy harvesting module that allows for charging the ICM at a high speed without burning the patient or overheating components of the ICM. Internally, the energy harvesting module includes at least two overlapping receiving coils that are spaced to be orthogonal to each other and that have a tilt angle of substantially 45°. Such overlapping wire combination allows to minimize mutual inductance of the solenoid coils and increase the rate at which energy can be provided to the energy harvesting module. Further, the rate at which the energy is transmitted from the outside can be increased by defining in a transmitting coil a substantially triangular gap.

A noise-separating cardiac monitor is provided. An implantable housing includes an external surface. A wireless antenna is shaped to wrap around an interior periphery of the implantable housing. Electrodes are provided on a ventral surface of the implantable housing to capture P-wave signals and R-wave signals. Electronic circuitry is provided within the wearable housing and includes a low power microcontroller. A front end circuit includes a signal lead operable to sense cardiac electrical potentials through one of the electrodes, a reference lead operable to sense the cardiac electrical potentials through another electrode, and a reference generator configured to inject a driven reference to the reference lead. The signal lead includes a coupling capacitor and a protection resistor associated with thermal noise. The thermal noise is not contained in the driven reference and not introduced to the reference lead. A non-volatile memory is electrically interfaced with the microcontroller.

A system and method for collecting operation data associated with a medical apparatus including an internal device implanted in a subject and an external device that is magnetically-coupled to and drives the internal device. The medical apparatus may be monitored to obtain raw data associated with the operation of the medical apparatus and one or more calculations may be performed on the raw data, wherein the raw data and/or calculated values may be associated with voiding frequency and voiding volume of the subject. A report may be generated from the raw data and/or calculated values. In addition, one or more signals may be sent to the external device and/or a docking station, or communicated by other means, to indicate to the subject that the operation of the medical apparatus should be altered.

The present disclosure relates to an enhanced intrauterine device. Some aspects may involve a body, at least one arm, at least one connector, a communication circuit, and a removal mechanism. The body may be inserted in a uterus. The at least one arm may in a first position extend radially from the body and in a second position be detached from the body. The at least one connector may link the at least one arm to the body such that the at least one arm remains linked to the body in both the first position and second position. The communication circuit may couple to at least one of the body and the at least one arm for responding to a first signal by transmitting a second signal. The removal mechanism may couple to body and may include a magnetic portion for removing the intrauterine device from the uterus.

There are provided a sensor device and a sensor system that consume less power, can be miniaturized, and are excellent in productivity. The sensor device has: a unit 1 having at least one type of power supply portion 13 selected from a power generation portion and a wireless power supply portion, a sensor portion 11 that detects target information and outputs a signal, a logic portion 12 that performs determination based on the signal, and a wireless communication portion 14 that transmits a result of the determination to the outside; and a sealing material that covers at least a part of the outer periphery of the unit 1. The unit 1 has the respective portions on one semiconductor substrate surface, and the respective portions are electrically connected to each other. Alternatively, the respective portions are formed on a plurality of semiconductor substrates, the semiconductor substrates on which the respective portions are formed are laminated, and the respective portions are electrically connected to each other.
