A highly elastic stent is made of an alloy that exhibits superelasticity at body temperature. 0 Pa\u22121; and a tensile modulus, determined according to ISO 527-2, of at least 1600 MPa measured on a test specimen prepared by injection molding according to ISO 1873-2. A mounting bar is secured to a distal end of the integral barrel wherein the mounting bar serves to attach the measuring device to an external surface. The member is comprised of a first material and the coupler is comprised of a second material. The right of payment is contingent upon a first yield per unit land area of the particular in the field less than second yield per unit land area of a geographic area by more than a threshold amount.
