One or more medication pumps are in fluid connection with respective ones of the reservoirs. A processor is connected with the sensors. The processor includes a memory that stores processing instructions to interpret the parameters and to determine a recommended medication to deliver to the patient based on the parameters, the recommended medication being one of the predetermined medications. The processor is operatively connected with the medication pumps. When a recommended medication is determined, the processor actuates the medication pump connected with the reservoir including the recommended medication to deliver the medication to the patient via the manifold and the delivery line.

A serviceable wearable cardiac treatment device for continuous extended use by an ambulatory patient includes a garment, a device controller, and an ingress-protective housing. The garment is configured to dispose therein a plurality of ECG sensing and therapy electrodes to monitor for and treat a cardiac arrhythmia in the patient. The device controller is configured to be in separable electrical communication with the plurality of ECG sensing and therapy electrodes and includes an impact-resistant energy core, and first and second circuit boards affixed to opposing sides of the impact-resistant energy core. The impact-resistant energy core includes a frame and at least one capacitor permanently bonded to the frame to form a unitary mass. The ingress-protective housing is configured to enable removal of the impact-resistant energy core and the first and second circuit boards during servicing.

A temporary pacing lead device comprises: an elongate body having a distal portion and a proximal end; an electrode array at the distal portion configured to deliver a pacing signal to target tissue; a displacement member attached to a first side of the distal portion; at least one anchoring element deployable from a second opposite side; and an interface at the proximal end of the elongate body. The interface is configured to couple to a pacing signal generator and/or a control handle to actuate the displacement member and/or anchoring element. The pacing generator can be a miniature pacing signal generator and/or a standard pacemaker device, and the interface can switch between providing the pacing signal from either of the two sources. The miniature pacing signal generator can include a protective element for the control and/or actuation elements at the proximal end.

Systems, apparatuses, and methods for electroporation ablation therapy are disclosed, with a protection device for protecting electronic circuitry, devices, and/or other components from induced currents and voltages generated during a cardiac ablation procedure. A system can include an ablation device near cardiac tissue of a heart. The system can further include a signal generator configured to generate a pulse waveform, where the signal generator coupled to the ablation device and configured to repeatedly deliver the pulse waveform to the ablation device in synchrony with a set of cardiac cycles of the heart. The system can further include a protection device configured to suppress induced current and voltage in an electronic device coupled to the protection device.

Systems and methods are described herein for generating surrogate cardiac electrical activation times from electrical activity monitored by a plurality of external electrodes. Surrogate cardiac electrical activation times that should be corrected may be identified, or determined, according to one or more metrics, and then such surrogate cardiac electrical activation times may be corrected according to various criterion.

Ambulatory medical devices may occasionally improperly administer a therapeutic stimulation pulse to a patient upon an incorrect detection of arrhythmia in the patient. To address these improperly administered therapeutic stimulation pulses, an ambulatory medical device includes processes and systems for verifying an initial declaration of an arrhythmia. The ambulatory medical device described include at least one first sensing electrode and at least one second sensing electrode distinct from the at least one first sensing electrode. First electrocardiogram (ECG) signals detected by the first sensing electrode are analyzed to provide an initial declaration of the arrhythmia condition of the patient. As a treatment protocol is being initiated in response to the analysis of the first ECG signals, second ECG signals detected by the second sensing electrode are analyzed to verify the initial declaration of the arrhythmia.

In one embodiment, a method to detect noise levels in electrocardiogram (ECG) signals is described. The method includes connecting to at least three sensing electrodes and obtaining a signal from each of the at least three sensing electrodes. The method also includes defining at least three channels between the at least three electrodes. The method includes calculating a morphological similarity value of at least one combination of the at least three channels based at least in part on the obtained signal from each of the at least three sensing electrodes and determining a noise level based at least in part on the calculated morphological similarity value.

Technologies and implementations for a wearable medical device (WMD). The technologies and implementations facilitate improved comfort and usability of WMDs. Additionally, the technologies and implementations include WMDs having wearable cardioverter defibrillator capabilities.

An assembly for placement of a cardiac, aortic or arterial implant. The assembly includes an insertion sheath of an introducer or of a delivery catheter, which is of a size smaller than that of an introducer, intended to be introduced into an artery of a human body. The metal support of an electrode of the external cardiac stimulator being integrated into the insertion sheath of a peripheral venous or arterial accessory catheter, or a sleeve around the accessory catheter, which is introduced into the peripheral vein or artery of a patient. The sheath of the accessory catheter or the sleeve is therefore directly in contact with a peripheral vein or artery of the patient.
