Abstract: Systems and methods to non-invasively measure sub-cutaneous processes in a patient are disclosed. Examples of systems may optically detect biological fluid properties. The optical detection techniques described herein may be incorporated into a wearable monitoring system. Examples of wearable monitoring systems may simultaneously measure a plurality of sensory modalities. Systems of the present disclosure may be mounted on the skin of a patient.

Abstract: Systems and methods for remotely monitoring blood flow that include an endovascular prosthesis. The endovascular prosthesis includes a conduit forming a lumen within a surrounding wall having an inner surface and an outer surface. A monitoring device is disposed on the wall forming the lumen. The monitoring device comprises a sensor element configured to detect a physical event and to generate an electrical parameter shift in response to the physical event. An antenna portion is configured to receive a first oscillating electrical signal from an interrogator device and to transmit a second oscillating electrical signal to the interrogator device. The second oscillating electrical signal is modulated by the electrical parameter shift.

Abstract: An endovascular prosthesis comprising: a conduit formed by a wall structure surrounding a lumen; a sensor element configured to generate an electrical parameter shift in response to a physical event, the sensor element integrated in the wall structure of the conduit, the wall structure includes at least one wire structure, where at least a part of the wire structure include a first metallic conduit, a second metallic conduit, and a sensor disposed between the first metallic conduit and the second metallic conduit, where the first and second metallic conduits are conductors in a monitoring device detecting the electrical parameter shift in the sensor; wherein the sensor is either a variable capacitive sensor, and the first metallic conduit and the second metallic conduit form the electrodes of the variable capacitor; or a variable resistor configured to generate a resistance change in response to the physical event.

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 in 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 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.
