A bridge device includes a housing, a plurality of electrodes exposed outside of the housing such that at least two of the plurality of electrodes can be concurrently placed in contact with a patient's skin. A controller is disposed within the housing. A first communications module is operably coupled to the controller and to the at least two of the plurality of electrodes. The first communications module is configured to allow the controller to communicate with an implantable medical device via at least two of the plurality of electrodes using conducted communication. A second communications module is operably coupled to the controller and is configured to allow the controller to communicate with a remote device external to the patient.

In some examples, a medical device system includes an electrode. The medical device system may include impedance measurement circuitry coupled to the electrode, the impedance measurement circuitry may be configured to generate an impedance signal indicating impedance proximate to the electrode. The medical device system may include processing circuitry that may be configured to identify a first component of the impedance signal. The first component of the impedance signal may be correlated to a cardiac event. The processing circuitry may be configured to determine that the cardiac event occurred based on the identification of the first component of the impedance signal.

A patient-worn arrhythmia monitoring and treatment device includes at least two pads configured to affix to skin on a torso of a patient. At least one of a pair of sensing electrodes is disposed on each one of the pads and configured to sense surface ECG activity of the patient. At least one of a pair of therapy electrodes is disposed on each one of the pads and configured to deliver one or more therapeutic pulses to the patient. A controller is in communication with the pairs of sensing and therapy electrodes and is configured to monitor for cardiac arrhythmias based on the sensed surface ECG activity and cause the delivery of the one or more therapeutic pulses. The device includes a removable garment to be worn about the torso to immobilize on the torso the one of the at least two pads to which the controller is coupled.

A wearable therapeutic device is provided. The wearable therapeutic device includes a garment, and the garment includes an electrode and a conductive thread. A control unit is coupled to the conductive thread and identifies an electrical connection between a conductive surface of the electrode and the conductive thread, and an alarm module can provide information about the positioning of the electrode in the garment based on the electrical connection.

A subcutaneously implantable device includes a housing, a clip attached to a top side of the housing, a first prong with a proximal end attached to the housing and a distal end extending away from the housing, and a first electrode on the first prong. The clip is configured to anchor the device to a muscle, a bone, and/or a tissue. The first prong is configured to contact a heart. The first electrode is configured to contact the heart. Sensing circuitry in the housing that is configured to sense an electrical signal from the heart, and therapeutic circuitry in the housing is in electrical communication with the first electrode and is configured to deliver electrical stimulation to the heart through the first electrode.

Apparatuses, systems and methods are provided that may include a system for patient monitoring and defibrillation. The system may include at least two defibrillation electrodes. The system may further include a first unit for physiological monitoring of a patient, including ECG monitoring circuitry for monitoring ECG of the patient. The first unit may store CPR chest compression data. The system may further include a second unit, separate from the first unit, which may communicatively couple with the first unit, for providing defibrillation pulses to the patient. The second unit may include a processor, communicatively coupled with the at least two defibrillation electrodes, for providing defibrillation pulses to the patient via the at least two defibrillation electrodes.

Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus. In addition, the methods and device allow for timed delivery of ventilations based on a condition of a thoracic cavity to increase the amount and efficiency of blood flow during a resuscitation procedure.

An example system for monitoring and delivering therapy to a patient includes a monitor module with patient monitoring capability, and a manifold that is operable to provide an electrical connection between the monitor module and cables connecting to sensors for collecting physiologic monitoring data of a patient, and to provide a gas connection between the monitor module and tubing for delivering treatment to or collecting additional physiologic monitoring data from the patient. The manifold includes a connector for mechanically connecting the manifold to the monitor module, and the connector also for mechanically disconnecting the manifold from the monitor module while maintaining the cables and the tubing coupled to the patient. In some examples, the system can also include a cot including a second set of monitoring electronics with patient monitoring capability, the cot including a port for coupling with the connector of the manifold.

A magnetic connection can be formed between a magnet set of a first device and magnet set of a second device. The magnetic strength of the magnetic connection can be modified by changing an orientation of a magnet set of a first device from a first orientation to a second orientation. The magnet set or a case in which the magnet set is disposed can be asymmetric, such that alternating between the first and second orientations results in different magnetic connections.
