ABSTRACT:
A system for quantifying pressure exerted on a bolus in a digestive tract of a patient includes: a catheter of sufficient length and insert into the digestive tract of the patient, a plurality of radiopaque pressure sensors on the catheter to output pressure data, a videofluoroscope for producing images of the digestive tract of the patient in which the bolus is moving in relation to the sensors, and equipment for recording a video record of a sequence of the images and the data, wherein the equipment combines each image with a substantially contemporaneous portion of the pressure data to form a video record sequence of images and the substantially contemporaneous portions of the pressure data.
The system produces a manofluorogram, which is a videotape record of the videofluoroscopic and contemporaneous pressure data, preferably with timing information. The system also produces a manofluorogram, which is an analysis of pressure data based on timing information derived from the videotape. A method of manufacture and method of use for the above are also set forth.
