  • Probe with variable geometry for measuring the radial strains in a sphincter of a living organism
    Patent number: 4566465
    Abstract: A probe for studying the visco-elastic behavior of sphincters of living organisms is comprised of an expansible head formed by three articulated groups disposed radially at 120.degree. intervals about a central axis. Each of the articulated groups is composed of a cross-piece which interconnects a rigid member, carrying a strain gauge on its outer surface, to the central axis. The cross-pieces are articulated at one end about the opposite ends of the rigid member and are articulated at the other end about two blocks which are carried by the central axis. The cross-pieces are constructed such that rotation of the central axis causes the distance between the rigid elements and the central axis to vary. A flexible shaft couples the central axis to a motor.
