An electrocardiography patch is provided. A backing includes an elongated strip with a midsection connecting two rounded ends. The midsection tapers in from each end and is narrower than each of the two ends. An electrode is positioned on each end of the backing on a contact surface to capture electrocardiographic signals. A circuit trace electrically is coupled to each of the electrodes in the pair. A battery is provided on an outer surface of the backing opposite the contact surface. Memory is provided on the outer surface of the backing to store data regarding the electrocardiographic signals. A processor is powered by the battery to write the data into the memory.

A method of determining signal quality in a patient monitoring device includes acquiring one or more signals using the patient monitoring device. One or more signal quality metrics are determined based on the one or more acquired signals. A noise condition is detected based on the one or more signal quality metrics, and a determination is made whether the noise condition should be classified as intermittent or persistent. One or more actions are taken based on the classification of detected noise as intermittent or persistent.

The present invention relates to methods for tuning treatment parameters in movement disorder therapy systems. The present invention further relates to a system for screening patients to determine viability as candidates for certain therapy modalities, such as deep brain stimulation (DBS). The present invention still further provides methods of quantifying movement disorders for the treatment of patients who exhibit symptoms of such movement disorders including, but not limited to, Parkinson's disease and Parkinsonism, Dystonia, Chorea, and Huntington's disease, Ataxia, Tremor and Essential Tremor, Tourette syndrome, stroke, and the like. The present invention yet further relates to methods of tuning a therapy device using objective quantified movement disorder symptom data acquired by a movement disorder diagnostic device to determine the therapy setting or parameters to be provided to the subject via his or her therapy device. The present invention also provides treatment and tuning remotely, allowing for home monitoring of subjects.

Described herein are external devices, and methods for use therewith, that are configured to communicate with one or more implantable medical devices (IMDs) implanted within a patient using conductive communication, wherein the external device includes or is communicatively coupled to at least three external electrodes that are in contact with the patient. Certain such methods involve the external device identifying, for each IMD, of the plurality of IMDs, which one of the plurality of communication vectors is a preferred communication vector for communicating with the IMD, based on respective indicators of conductive communication quality that are determined for the plurality of communication vectors. Certain embodiments involve determining when there should be a reassessment of which one of the plurality of communication vectors is the preferred communication vector for communicating with an IMD, and in response thereto, identifying an updated preferred communication vector for communicating with the IMD.

Techniques are disclosed for gating state transitions of a medically related device. Specifically, detection that a particular condition is satisfied can directly or indirectly trigger switching the medically related device from operating in a normal operation mode to a suppressed operation mode.

A spirometry system operable to measure airflow through an air passage defined by a mouthpiece including one or more contact sensors configured to generate at least one mouth contact signal indicative of user mouth contact with the proximal portion of the mouthpiece. The spirometry system can further include an airflow sensor configured to generate an airflow signal corresponding to airflow within the air passage, and processor circuitry communicatively coupled to the one or more contact sensors and to the airflow sensor. The processor circuitry can be configured to determine an indication of an amount of user mouth contact for use with a measurement of airflow by the processor circuitry.

Disclosed is a surgical instrument, comprising a shaft, an articulation joint extending distally from the shaft, and an end effector extending distally from the articulation joint. The end effector comprises a jaw, and a staple cartridge seatable in the jaw. The staple cartridge comprises a cartridge body, staples removably stored in the cartridge body, and a first antenna. The surgical instrument further comprises a remote power source configured to supply power, a second antenna configured to cooperate with the first antenna when the staple cartridge is seated in the jaw to transmit at least one of the power and a data signal to the staple cartridge, and a tuning electronics package located in a cavity in a proximal portion of the end effector. The tuning electronics package is configured to facilitate a locally tunable wireless transmission of the at least one of the power and the data signal.

An extended wear electrocardiography and physiological sensor monitor recorder is provided. A set of electrical contacts extend from a bottom surface of a proximal end of a sealed housing. The sealed housing includes electronic circuitry, including an electrographic front end circuit to sense electrocardiographic signals and a micro-controller interfaced to the electrocardiographic front end circuit to sample the electrocardiographic signals. A patient feedback button located is on a top surface of the proximal end of the sealed housing and positioned above the feedback bottom on the distal end.

In an embodiment, an apparatus, such as a sensor package, includes a sensor, an antenna, and a power circuit. The package is configured for attachment to an object or a subject, for example a patient in need of clinical monitoring. The sensor package is configured to sense a condition or conditions related to the object or subject, and configured to generate a sense signal according to the sensed condition. The sensor patch may include a dual power source and means for switching between power sources, such as NFC and battery. The sensor patch may also include dual radios. As practiced, an NFC radio can be supplemented with a Bluetooth or other LAN radio for data logging. Systems for monitoring sensor patches may include methods for monitoring or tracking location of the patches. In one instance, patches worn by patients are used to triage patients and remotely monitor one or more clinical signs and radio proximity; the system notifies caregivers in real time if the clinical data is indicative of a worsening condition and guides the caregivers to the patient by the shortest possible path, even in a busy facility such as an emergency room.
