Abstract

A wearable cardiac therapeutic device includes a plurality of ECG sensing electrodes configured to sense ECG signals regarding a cardiac function of a patient; a plurality of therapy electrodes configured to deliver transcutaneous defibrillation shocks or transcutaneous pacing pulses to the patient's heart; and a support garment configured to support and hold the plurality of ECG sensing electrodes and the plurality of therapy electrodes against the patient's body. The support garment includes one or more features for improving and enhancing the patient's experience in wearing the support garment with respect to wearability, comfort, aesthetics, and assembly and usage of the device.

First claim

1 .- 116 . (canceled)

117 . A cardiac therapeutic device support garment for easy and quick donning and removal about the torso of the patient, comprising:
a plurality of ECG sensing electrodes configured to sense ECG signals regarding a cardiac function of a patient; a plurality of therapy electrodes to deliver transcutaneous defibrillation shocks or transcutaneous pacing pulses to the patient's heart in the event of a life-threatening cardiac arrhythmia; and the support garment configured to support and hold the plurality of ECG sensing electrodes and the plurality of therapy electrodes against the patient's body, the support garment comprising: a back portion; a belt defined by side portions extending from the back portion and around a front of the patient's torso; and a closure mechanism configured to connect the side portions at the front of the patient's torso in a manner to facilitate the support garment to support and hold the plurality of ECG sensing electrodes while the ECG sensing electrodes senses the ECG signals regarding the cardiac function of the patient and while the plurality of therapy electrodes delivers the transcutaneous defibrillation shocks or transcutaneous pacing pulses to the patient's heart, the closure mechanism comprising: a first clasp member disposed on one of the side portions; and a second clasp member disposed on another of the side portions, the second clasp member being identical to the first clasp member, wherein the first and second clasp members are configured to form a mating engagement with each other to secure the side portions, and wherein the first and second clasp members are configured to facilitate mutual alignment and securing of the side portions at the front of the patient, provide tactile feedback to a user that the clasp members are matingly engaged and thereby indicate to the patient that the cardiac therapeutic device has been correctly donned to protect the patient from life-threatening cardiac arrhythmia events, and have an appealing aesthetic appearance.

118 . The wearable cardiac therapeutic device according to claim 117 , wherein at least one of the first and second clasp members is connected to the respective side portion by a belt attachment and an adjustable slider.

119 . The wearable medical device according to claim 117 , further comprising a third clasp member disposed on the same side portion as the first clasp member at a different location along a length of the side portion, the third clasp member being identical to the first clasp member and the second clasp member and being configured to form a mating with the second clasp member to secure the side portions.

120 . The wearable medical device according to claim 117 , wherein the first clasp member and the second clasp member comprise corresponding protrusion and recess features configured to indicate proper alignment of the clasp members to form the mating engagement and to engage each other to secure the clasp members in the mating engagement, and wherein the corresponding protrusion and recess features are also configured to snap together to provide the tactile feedback to the user.

121 . The wearable medical device according to claim 117 , wherein the first clasp member and the second clasp member each comprise at least one smooth-textured protrusion disposed on a rough-textured exterior surface, the smooth-textured protrusions being configured to align with each other to indicate proper alignment of the clasp members to form the mating engagement.

122 . The wearable medical device according to claim 117 , wherein the support garment comprises a gray color fabric material, and wherein the first clasp member and the second clasp member each have a color complementary to the gray color fabric material of the support garment.

123 . The wearable medical device according to claim 117 , wherein the closure mechanism has a height of approximately 40 mm-50 mm, more particularly approximately 45 mm-47 mm, more particularly 45.75 mm,
wherein the closure mechanism has a width of approximately 20 mm-35 mm when the first and second clasp members form the mating engagement, more particularly approximately 26 mm-28 mm, more particularly 27.2 mm, and wherein the closure mechanism has a maximum thickness of approximately 3 mm-8 mm, more particularly approximately 5 mm-6 mm, more particularly approximately 5.75 mm.

124 . The wearable cardiac therapeutic device according to claim 117 , further comprising a medical device controller in communication with the plurality of ECG sensing electrodes and the plurality of therapy electrodes, the medical device controller configured to:
detect a patient event based, at least in part, on the ECG signals sensed by the plurality of ECG sensing electrodes; and provide a therapy to the patient via the plurality of therapy electrodes in response to a detection of the patient event, wherein the patient event detected by the medical device controller comprises one or more of bradycardia, ventricular tachycardia or ventricular fibrillation, atrial arrhythmias such as premature atrial contractions, multifocal atrial tachycardia, atrial flutter, and atrial fibrillation, supraventricular tachycardia, junctional arrhythmias, tachycardia, junctional rhythm, junctional tachycardia, premature junctional contraction, and ventricular arrhythmias such as premature ventricular contractions and accelerated idioventricular rhythm.

125 . The wearable cardiac therapeutic device according to claim 124 , wherein the medical device controller is configured to issue an audible alarm to notify the patient that the patient event has been detected.

126 . The wearable cardiac therapeutic device according to claim 124 , wherein the medical device controller comprises one or more input components configured to receive a response input from the patient, wherein the one or more input components comprise at least one of: a response button; a touch screen; an audio detection device; a motion sensor; a contact sensor; a pressure sensor; a gesture recognition component; or a patient physiological sensor.

127 . The wearable cardiac therapeutic device according to claim 117 , wherein the support garment comprises a plurality of circular hook-and-loop fastener patches on an inside surface thereof for fastening and supporting the plurality of ECG sensing electrodes on the support garment,
wherein each of the plurality of ECG sensing electrodes comprises a corresponding hook-and-loop fastener configured to connect to a respective circular hook-and-loop fastener patch on the support garment, and wherein the plurality of circular hook-and-loop fastener patches are configured to facilitate alignment and assembly of the respective ECG sensing electrodes on the support garment and provide for fastening and support for the respective ECG sensing electrodes on the support garment independent of the rotational orientation of the respective ECG sensing electrodes.

128 . The wearable cardiac therapeutic device according to claim 127 , wherein the plurality of circular hook-and-loop fastener patches and the corresponding hook-and-loop fasteners are color coded to facilitate assembly of each of the plurality of ECG sensing electrodes to a corresponding predetermined location on the inside surface of the support garment.

129 . The wearable cardiac therapeutic device according to claim 117 , wherein the support garment comprises:
a plurality of support pockets disposed on an inside surface of the support garment for supporting the plurality of therapy electrodes on the support garment; and a plurality of handling tab members, at l
