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.
Claims41
A prosthesis for monitoring a characteristic of flow, said prosthesis comprising:
- a first tubular prosthesis having proximal and distal ends;
- and a lumen extending therebetween;
- a second tubular prosthesis having a lumen extending therethrough,
- a non-optical sensor for detecting a characteristic of fluid flowing through the lumen of the first tubular prosthesis;
- and
- a layer of material provided over the sensor, sealingly coupling the sensor to a surface of the first tubular prosthesis without embedding the sensor within the first tubular prosthesis, wherein the sensor is insulated from contact with fluid flowing through the lumen;
- wherein the second tubular prosthesis is coaxially mounted to the first tubular prosthesis such that the non-optical sensor is not interposed between the first and second tubular prosthesis.
