System and method for collecting clinical data associated with a medical apparatus including an implantable device
A system and method for collecting operation data associated with a medical apparatus including an internal device implanted in a subject and an external device that is magnetically-coupled to and drives the internal device. The medical apparatus may be monitored to obtain raw data associated with the operation of the medical apparatus and one or more calculations may be performed on the raw data, wherein the raw data and/or calculated values may be associated with voiding frequency and voiding volume of the subject. A report may be generated from the raw data and/or calculated values. In addition, one or more signals may be sent to the external device and/or a docking station, or communicated by other means, to indicate to the subject that the operation of the medical apparatus should be altered.

The support structure includes patches, clips, eyeglasses, head mounted gear and the like, containing passive or active sensors positioned at the end of the tunnel with sensing systems positioned on and accessing a physiologic tunnel.
HEART RHYTHM DETECTION CONTROL METHOD AND TERMINAL
A heart rhythm detection control method and a terminal relate to the field of terminal technologies, and can reduce, to some extent, an inaccurate heart rhythm detection result displayed by a terminal. The heart rhythm detection control method includes: detecting motion data of the terminal in response to a heart rhythm detection instruction input by a user; and if the motion data is greater than a motion data threshold, displaying first prompt information in a user interface. The first prompt information is used to prompt the user that heart rhythm detection is suspended.
CMOS-BASED LOW-POWER, LOW-NOISE POTENTIOSTAT CIRCUIT AND ITS INTEGRATION WITH AN ENFM-BASED GLUCOSE SENSOR
The present disclosure presents glucose sensing methods and systems. One such system comprises an electrospun-nanofibrous-membrane (ENFM)-based amperometric glucose sensor integrated on a silicon chip, in which the glucose sensor has a working electrode, a reference electrode, and a counter electrode, wherein the working electrode comprises an ENFM-based sensing electrode. The system further comprises a potentiostat circuit integrated on the silicon chip such that the potentiostat circuit comprises a voltage control unit to control a voltage difference between the working electrode and the reference electrode and a transimpedance amplifier to measure a current flow between the working electrode and the counter electrode, in which a strength of the current flow corresponds to an amount of glucose present in a sample of blood on the glucose sensor.
Cointegration filter for a catheter navigation system
A system and method for determining a position of a medical device within a body are provided. The system includes an electronic control unit that receives position signals from position sensors of a first type and a second type disposed on the device and applies a filter to each of the position signals to obtain filtered estimated positions for each sensor. The unit computes a spline connecting the position sensors of the first type responsive to the filtered estimated positions for the sensors and estimates a spline position for the sensor of the second type along the spline. The unit generates maps between the spline position and filtered and unfiltered estimated positions for the sensor of the second type and determines actual positions for the sensors of the first type responsive to the filtered estimated position for the sensors and a composite map of the two maps.

Methods and devices to monitor an analyte in body fluid are provided. Embodiments include continuous or discrete acquisition of analyte related data from a transcutaneously positioned in vivo analyte sensor automatically or upon request from a user. The in vivo analyte sensor is coupled to an electronics unit holding a memory with instruction to cause processing circuitry to initiate a predetermined time period that is longer than a predetermined life of the sensor, during the predetermined time period, convert signals from the sensor related to glucose to respective corresponding glucose levels, without relying on any post-manufacture independent analyte measurements from a reference device, and at the expiration of the predetermined time period, disable, deactivate, or cease use of one or more feature.
