Abstract: Systems and devices for a conformable wearable device are described. The wearable device may include a sensor module comprising one or more sensors configured to acquire physiological data from a user. In some cases, the wearable device may include a deformable material coupled with the sensor module and configured to transition between a planar orientation in an unworn state and a non-planar orientation in a worn state and a flexible material that at least partially encases the sensor module and the deformable material.

Abstract: An electrocardiogram (ECG) measurement method with reduced power consumption for displaying a six-lead ECG waveform using a portable apparatus and a smartphone is disclosed. The apparatus includes three electrodes configured to contact both hands and a left leg of a user, two contact detectors configured to detect a contact status of the user, and a microcontroller. Upon detecting simultaneous contact on all three electrodes, the microcontroller transitions from a low-power mode to an active mode, activating two amplifiers and a constant voltage generator to acquire two ECG signals. The two ECG signals are converted into two digital lead signals and wirelessly transmitted to the smartphone. The smartphone generates four additional derived lead signals and displays a six-lead ECG waveform based on the two received signals.

Abstract: The present invention provides a catheter for treating occlusions in body lumens. The catheter includes a catheter body that is fillable with fluid. An impactor is connected to the distal end of the catheter body and has a proximal end inside the catheter body and a distal end outside the catheter body.
