A handheld device measures all vital signs and some hemodynamic parameters from the human body and transmits measured information wirelessly to a web-based system, where the information can be analyzed by a clinician to help diagnose a patient. The system utilizes our discovery that bio-impedance signals used to determine vital signs and hemodynamic parameters can be measured over a conduction pathway extending from the patient's wrist to a location on their thoracic cavity, e.g. their chest or navel. The device's form factor can include re-usable electrode materials to reduce costs. Measurements made by the handheld device, which use the belly button as a fiducial marker, facilitate consistent, daily measurements, thereby reducing positioning errors that reduce accuracy of standard impedance measurements. In this and other ways, the handheld device provides an effective tool for characterizing patients with chronic diseases, such as heart failure, renal disease, and hypertension.

Methods, devices, systems, and kits are provided that buffer the time spaced glucose signals in a memory, and when a request for real time glucose level information is detected, transmit the buffered glucose signals and real time monitored glucose level information to a remotely located device, process a subset of the received glucose signals to identify a predetermined number of consecutive glucose data points indicating an adverse condition such as an impending hypoglycemic condition, confirm the adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the adverse condition, where confirming the adverse condition includes generating a notification signal when the impending hypoglycemic condition is confirmed, and activate a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.

A wearable device includes one or more sensors of information from a subject. The wearable device may have an electronic assembly supported by a base. The electronic assembly may include a sensor data collection system configured to control collection of sensor data related to one or more characteristics of a subject and one or more processors. the sensor data collection system may include a controller configured to control sequencing and scheduling of the sensor data collection, and a buffer configured to receive and buffer data corresponding to the sensor data collected from the one or more sensors in accordance with a signal provided by the controller. The one or more processors may be configured to receive the buffered data from the buffer in accordance with a wake signal; process the received data; and output the processed data. Scheduling and sequencing the sensor data collection by the sensor data collection system may be decoupled from the processor such that the processor may be in a low-power sleep mode during data collection and in a normal power mode to process data received from the buffer.

Vessel occlusion coils disclosed that have a primary configuration for delivery and a secondary configuration for deployment that is conferred upon the devices by a stretch resistant member. In the secondary configuration, the stretch resistant member forms a stiffer coil and may have a greater diameter, and a more complex shape having some interior space, at one end than at the other end, for improved anchoring of the device in the vessel. The methods include intravascular delivery and deployment for implanting one or more vessel occlusion devices.

The present invention relates generally to a method for preventing gravity-induced loss of consciousness (G-LOC), which arises from increased acceleration during flight, and more particularly, to a G-LOC warning method and system using a G-LOC warning algorithm, which detects, in advance, risk factors that cause a G-LOC state by monitoring a change in the electromyogram (EMG) signal in real time. According to the G-LOC warning method and system using the G-LOC warning algorithm of the present invention, because information about the EMG signal is measured and collected in real time, changes in the EMG signal of a pilot who is exposed to high levels of acceleration during a flight maneuver are measured and checked on the spot.

Embodiments described herein are directed to an automatic catheter measurement system for determining a length of a catheter required to extend between an insertion site and a target location, prior to placement of the catheter. The system can include a measurement device that can be aligned with, and map, a three-dimensional arrangement of one or more external landmarks. The measurement device can include magnetic and/or fiber optic systems to map the external landmarks. The system then determines a framework to provide a predicted catheter length required to extend between the insertion site and target location. The measurement device can also be included with the catheter during placement to confirm the actual catheter length and improve the accuracy of future predicted frameworks.
