tubular member 26 and second tubular member 27 can assume a different retracted and or extended configuration independently from each other thus the first section and second section of the plurality of tissue contactor members can also assume radially expanded or contracted configuration independently of each other by having a u201c double mound u201d configuration the structure provided by the two sections of the plurality of tissue contactor members can exert adequate pressure to the surrounding tissue of an annular organ structure for stabilizing the placement of the distal section of the catheter system and or suitable for compressively sandwiching the inner wall of the annular organ structure the basic principle for the tissue contactor member as illustrated in fig4 and fig7 of one or more embodiments of the invention is to compress the target tissue e g annulus sphincter tumor and the like for enhanced site specific application of tissue shrinkable energy the compression may come from sandwich type setup such as from two opposite tissue contactor members at a suitable angle arrangement to compress the target tissue fig5 illustrates a cut away view of a tubular tissue contactor member 11 integrated with a tissue shrinkable energy emitting element 8 the energy emitting element 8 is fitted with at least one temperature sensor e g a thermocouple type a thermister type or any miniature temperature sensor known to one of ordinary skills in the relevant art which are coupled via temperature sensing wires 15 16.
