Abstract: A system, device and method for measuring markers for a periprosthetic joint infection in a sample of synovial fluid. A sensor reader device includes a vial receptacle for receiving a vial containing synovial fluid. A light source illuminates the vial and an optical sensor detects light scattered and/or absorbed by white blood cells in the fluid sample. An electrical signal corresponding to the intensity of the light received at the optical sensor is detected. A white blood cell concentration is determined from the electrical signal value. The sensor reader device also includes one or more immunoassay strip receptacles. Immunoassay strips for other marker are inserted into the receptacles. Immunoassay optical sensors detect light generated by the immunoassay reaction on the immunoassay strip to determine the concentration of the marker. In example implementations, the device includes an immunoassay strip reader for leukocyte esterase and c-reactive protein.

Abstract: A prosthesis for monitoring a characteristic of flow includes a first tubular prosthesis having a lumen and a sensor for detecting the characteristic of flow through the lumen. The sensor may be covered with another tubular prosthesis or by a layer of material ire order to insulate the sensor from the fluid flow. A pocket may be formed between the tubular prosthesis and the adjacent layer of material or prosthesis and the sensor may be disposed in the pocket.

Abstract: A system, device and method for automatically and remotely acquiring sensor data from a wearable patch mounted on a patient. An example device implemented as a wearable patch includes a sensor assembly comprising a plurality of sensors configured to detect a corresponding plurality of sensory modalities and generate electrical signals representing the sensory modalities. A signal converter receives the electrical signals from the plurality of sensors and converts the signals to sensor data signals comprising a data representation of at least one of the electrical signals. A communications interface communicates the sensor data signals to a sensor data processing system.

Abstract: A prosthesis for monitoring a stenosis in the prosthesis comprises a tubular prosthesis having a proximal portion, a distal portion, and a lumen extending therebetween. A sensor is coupled to the tubular prosthesis and disposed at an effective predetermined location on the tubular prosthesis so that the sensor may sense a presence of the stenosis in the lumen.

Abstract: A method for detecting a stenosis in a prosthesis includes providing a tubular prosthesis having a sensor coupled to the prosthesis and implanting the tubular prosthesis in a native fluid conduit. The sensor senses the stenosis and captures data that characterizes the stenosis. A spectral analysis of the data may then be performed in order to provide a frequency spectrum of the data. The frequency spectrum may be examined in order to identify a break frequency value in the frequency spectrum. The break frequency may then be translated into a percentage of stenosis in the tubular prosthesis.

Abstract: A method for assessing fluid flow in a conduit includes sensing the fluid flow with a sensor and generating data from the sensor that relates to the sensed fluid flow. The data is output from the sensor and filtered so that it may be interpreted to characterize the fluid flow. The conduit may be a prosthesis such as stent, a stent-graft or a prosthetic vascular graft and the flow may be any body fluid such as blood, bile, or cerebrospinal fluid.
