A calibration method and related systems for colorimetric chemical assay and a fluid sensor apparatus using the same are provided. Reference measurements are taken from both a digital camera and a spectrometer. The digital camera is installed in the fluid sensor apparatus. Subsequently, color measurements from the digital camera are then converted and compared to prior spectrometric measurements to perform a colorimetric analysis.

Systems and methods for device-independent color measurements for colorimetric sensing

The disclosed techniques include applying, using a voltage controller, multiple voltage pulses to a working electrode of a two-electrode sensor probe, and measuring, using a current sensor, the current response to the applied multiple voltage pulses. The techniques also include analyzing, using a processor, the measured current response, and calibrating, using a processor, the current sensor on the basis of the analyzed measured current response. The techniques further include determining, using a processor, a glucose concentration value on the basis of the calibrated current sensor, and transmitting, using a transmitter, the determined glucose concentration value to a receiver.

Miniaturized analyte sensor

A neuromodulation therapy is delivered via at least one electrode implanted subcutaneously and superficially to a fascia layer superficial to a nerve of a patient. In one example, an implantable medical device is deployed along a superficial surface of a deep fascia tissue layer superficial to a nerve of a patient. Electrical stimulation energy is delivered to the nerve through the deep fascia tissue layer via implantable medical device electrodes.

Minimally invasive implantable neurostimulation system

A medical device system for delivering a neuromodulation therapy includes a delivery tool for deploying an implantable medical device at a neuromodulation therapy site. The implantable medical device includes a housing, an electronic circuit within the housing, and an electrical lead comprising a lead body extending between a proximal end coupled to the housing and a distal end extending away from the housing and at least one electrode carried by the lead body. The delivery tool includes a first cavity for receiving the housing and a second cavity for receiving the lead. The first cavity and the second cavity are in direct communication for receiving and deploying the housing and the lead coupled to the housing concomitantly as a single unit.

Disclosed herein are sensors for sensing analyte concentration values, and methods of operating such sensors. The sensors include a sensor probe comprising two electrodes; a voltage controller operably connected to the two electrodes of the probe, the voltage controller operable to apply multiple voltage pulses to one of the electrodes; a current sensor operable to measure a current response to the multiple voltage pulses; and a processor module operably connected to the current sensor, the processor module operable to calibrate the current sensor on the basis of the current response.

The invention relates to a fluid sensor apparatus and a related sensor card for determining and/or monitoring a pH and/or solute concentration in a fluid. The fluid sensor apparatus can be used in any application requiring the detection of fluid components or concentrations of solutes, and in an exemplary embodiment, is used to detect ammonia concentration and/or pH in dialysis fluid. The fluid sensor apparatus has a camera, a light source positioned opposite to the camera, and a receiving slot for positioning a removable sensor card between the camera and the light source such that both sides of the sensor card are exposed to the sampled fluid.

Fluid sensor apparatus

The invention relates to a colorimetric gas detector for determining and monitoring gaseous substances. The colorimetric gas detector can be used in any application requiring the detection of substances in a gaseous environment. The colorimetric gas detector has a photodetector, a light source positioned opposite to the photodetector, and a receiving slot for positioning a colorimetric media between the camera and the light source.
