Abstract
(EN)
A system for providing real-time measurements of constriction pressure applied by the inner surface of a body lumen, such as a sphincter, includes a probe (10) comprising an elongated core member (24) having a matrix of pressure transducer regions (28) distributed over the surface of the elongated core member (24). The preferred matrix of pressure transducer regions is addressed by a first inner array of substantially parallel electrically conductive strips (36) conformed to at least a portion of the elongated core member, the first array (36) being disposed in overlapping relationship with a second outer array of substantially parallel electrically conductive strips (30), and substantially conformed axially to at least the same portion of the elongated core member, so as to provide a matrix of intersection regions.

L'invention concerne un système pour effectuer des mesures en temps réel de la pression de constriction appliquée par la surface interne d'une lumière du corps, tel qu'un sphincter. Ce système comprend une sonde (10) comportant un élément central allongé (24), une matrice de zones de capteurs de pression (28) étant répartie sur la surface de l'élément central allongé (24). La matrice préférée de zones de capteurs de pression est desservie par un premier ensemble intérieur de bandes électriquement conductrices sensiblement parallèles (36) adaptées à au moins une partie de l'élément central allongé. Le premier ensemble est disposé de manière à chevaucher un deuxième ensemble extérieur de bandes électriquement conductrices sensiblement parallèles (30), et est placé de manière sensiblement axiale par rapport à au moins la même partie de l'élément central allongé, afin de constituer une matrice de zones se recoupant.
