A wearable cardiac monitoring and treatment device for improved skin interface contact and easy assembly and disassembly includes a garment including an inner surface and an outer surface, ECG sensing electrodes, and at least one stiffener forming a section of the garment in proximity to one or more of the ECG sensing electrodes. The at least one stiffener is configured to resist rotation or pulling away of the one or more of the ECG sensing electrodes from a patient's torso. The device includes therapy electrodes, at least one separate module including a therapy delivery circuit, and a controller. The device includes compartments configured to receive the therapy electrodes and at least one separate module, and retention loops configured to route external wires extending between at least the therapy electrodes and at least one separate module, where the compartments and retention loops are disposed on the outer surface of the garment.

Garments for wearable cardiac monitoring and treatment devices

A cardiac monitoring and treatment system includes a controller, a first wearable portion, and a second wearable portion separate from the first wearable portion. The first wearable portion includes an elongated strap configured to encircle a thoracic region of a patient, a plurality of ECG sensing electrodes disposed about the elongated strap, one or more receiving ports configured to receive one or more additional components including a treatment electrode and/or an additional sensor, and a plurality of conductive wires configured to couple the plurality of ECG sensing electrodes and the one or more receiving ports with the controller. The second wearable portion is configured to be worn over at least one shoulder of the patient and includes a wearable substrate, one or more treatment electrodes disposed on the wearable substrate, and at least one conductive wire configured to releasably connect the one or more treatment electrodes to the controller.

Modular garment for a wearable medical device

A wearable cardiac monitoring and treatment device includes a garment, a plurality of ECG electrodes, a plurality of therapy electrodes, a therapy delivery circuit, and one or more sensors configured to monitor one or more physiological signals of the patient. The device also includes a controller configured to detect an arrhythmia condition, cause the therapy delivery circuit to deliver one or more therapeutic pulses to the patient on detecting the arrhythmia condition, detect that the garment is no longer worn about the torso of the patient prior to expiration of at least a prescribed duration of wear by detecting a loss of signal for at least a threshold period of time from one or more of the plurality of ECG sensing electrodes and/or one or more of the one or more sensors, and issue a notification that the garment is no longer worn about the torso of the patient.

An ergonomic and unobtrusive cardiac monitoring and treatment device for continuous wear includes a band, ECG sensing electrodes and treatment electrodes configured to deliver an electrotherapy, one or more sensor ports for receiving one or more physiological sensors, and a controller for analyzing an ECG signal of a patient and causing a delivery of electro therapy. The band is configured to be worn about a thoracic region and has a vertical span of between about 1 to about 15 centimeters. The band is configured to be immobilized relative to a skin surface of the thoracic region of the patient by exerting one or more compression forces against the thoracic region. The device can include at least two separate wearable portions comprising a band portion including ECG sensing electrodes and/or other physiological sensors, and a second wearable portion optionally separable from the band portion, the second wearable portion including treatment electrodes.

An injector system for injecting fluid includes a syringe and an injector. The syringe includes a body and a plunger movably disposed within the body. The plunger has at least one flexible leg extending toward the rearward end of the body. The injector has a housing with a front plate, a drive member at least partially disposed within the housing and operable to engage the plunger, and a syringe release assembly operable to release the syringe. The syringe assembly includes a syringe release gear that forms an enclosure for receiving the syringe when the syringe is fully seated within the housing and a plunger release tube surrounding at least a portion of the drive member. The plunger release tube has a first end rotationally engaged with the syringe release gear. Rotation of the syringe release assembly releases the at least one flexible leg from the drive member.

System for syringe engagement to an injector

A wearable cardiac monitoring and treatment device includes a garment, a plurality of ECG electrodes and a plurality of therapy electrodes supported by the garment. A fastener is configured to secure the garment about a torso of the patient for a prescribed duration. A disengagement sensor to provides an indication of disengagement of the fastener prior to expiration of the prescribed duration in which the garment is no longer secured about the torso of the patient. The device includes a therapy delivery circuit coupled to the plurality of therapy electrodes and configured to deliver one or more therapeutic pulses. A controller coupled to therapy delivery circuit is configured to analyze an ECG signal monitored by the plurality of ECG electrodes and, upon detecting one or more treatable arrhythmias, cause the therapy delivery circuit to deliver the one or more therapeutic pulses to the patient.
