SOLID STATE SPHINCTER MYOMETERS

摘要

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.
