Abstract: Epidermal electronics are sensors with mechanical properties matching human epidermis. Their manufacturing process includes photolithography and dry and wet etching within cleanroom facilities. The high cost of manpower, materials, photo masks, and facilities greatly hinders the commercialization potential of disposable epidermal electronics. In contrast, an embodiment of the invention includes a low cost, high throughput, bench top “cut-and-paste” method to complete the freeform manufacture of epidermal sensor system (ESS) in minutes. This versatile method works for many types of thin metal and polymeric sheets and is compatible with many tattoo adhesives or medical tapes. The resultant ESS is highly multimaterial and multifunctional and may measure ECG, EMG, skin temperature, skin hydration, as well as respiratory rate. Also, a stretchable planar coil made of serpentine ribbons can be used as a wireless strain gauge and/or a near field communication (NFC) antenna. Other embodiments are described herein.

Abstract: In some examples, a medical device is configured to deliver high dose electrical stimulation therapy to a patient by at least generating and delivering an electrical stimulation signal having a relatively high duty cycle, and a stimulation intensity less than a perception or paresthesia threshold intensity level for the patient. The pulses of the electrical stimulation signal may each have a relatively low amplitude, but due at least in part to a relatively high number of pulses per unit of time, a dose of the electrical stimulation may be high enough to elicit a therapeutic response from the patient.

Abstract: An example method is performed by a current defibrillator and includes determining that a memory embedded within a therapy cable coupled to the current defibrillator stores data indicative of a previous shock delivered to a patient, the previous being delivered using a previous defibrillator. The method also includes obtaining the data indicative of the previous shock, and setting an energy level for a subsequent shock based on the data indicative of the previous shock. The method further includes delivering the subsequent shock to the patient at the energy level for the subsequent shock.

Abstract: Embodiments of this disclosure are directed to a wearable cardioverter defibrillator (“WCD”) system design in which a WCD implements an alert prioritization scheme to provide the patient with feedback in an order that is less likely to cause confusion. Different conditions (e.g., device status, equipment condition, or physiologic condition) are prioritized based on an analysis of severity of the condition and timeliness of user action needed. The prioritization scheme defines what alert, if any, is presented to the user by the WCD system as a result of various conditions. Generally stated, an alert for the highest priority condition currently detected is presented to the user and maintained until that condition either changes or becomes surpassed in the prioritization scheme.

Abstract: A stereotactic frame includes a vertical column that extends up from a base. A first laterally extending support arm extends from a first side of the column and a second laterally extending support arm extends from a second side of the column. One of the first or second support arms may include a transducer assembly. The transducer assembly may move a focal point of the transducer in different lateral and longitudinal horizontal positions and different vertical positions. The transducer assembly also may move the focal point of the transducer beam into different pivoting angled positions. The stereotactic frame applies repeatable ultrasonic energy to targets inside a patient without using invasive attachment procedures and without having to repeatedly use expensive magnetic resonance imaging (MRI) machines.

Abstract: An intracardiac ventricular pacemaker is configured to detect a ventricular diastolic event from a motion signal received by a pacemaker control circuit from a motion sensor. The control circuit starts an atrial refractory period having an expiration time set based on a time of the detection of the ventricular diastolic event. The control circuit detects an atrial systolic event from the motion signal after expiration of the atrial refractory period and controls a pulse generator of the pacemaker to deliver a pacing pulse to a ventricle of a patient's heart at a first atrioventricular pacing time interval after the atrial systolic event detection.

Alternately, the methods and systems may identify effective electrodes and other stimulation parameters based on preferential stimulation of different types of neural elements. These methods and systems can further facilitate programming an electrical stimulation system for stimulating patient tissue.
