Abstract:
1. A catheter comprising: an elongated catheter body having proximal and distal ends and at least one lumen therethrough; a three-dimensional ablation assembly at the distal end of the catheter body, said assembly having a seamless cylindrical structure defining a length and a circumference, the assembly adapted to assume a deployed configuration, the seamless cylindrical structure being configured with a plurality of longitudinal slats in a sidewall that predictably bow outwardly in the radial direction to a greater circumference when said length is decreased, the seamless cylindrical structure including a proximal end with a first length and a distal end with a second length, and the longitudinal slats in the sidewall extend between the first length and the second length; the assembly also having a ribbon electrode extending around an external circumference of a cross-section of said seamless cylindrical structure, said ribbon electrode adapted to expand from said circumference to said greater circumference with said structure.
