1. An ablation catheter apparatus comprising:
an elongated body member having a proximal end, and a distal end; a basket at the distal end, the basket comprising a plurality of radially expanding splines, the plurality of radially expanding splines including at least a first radially expanding spline, a second radially expanding spline, and a third radially expanding spline; a first electrode located on the first radially expanding spline, the first electrode configured to apply energy to tissue adjacent to the first radially expanding spline during an ablation procedure; and a second electrode located on the second radially expanding spline, the second electrode configured to apply energy to tissue adjacent to the second radially expanding spline during the ablation procedure; wherein at least one of the first radially expanding spline, the second radially expanding spline, or the third radially expanding spline includes:
a first and a second aperture or aperture portion;a lumen;an optical emitting element inside the lumen configured to emit optical radiation through the first aperture and into adjacent tissue during the ablation procedure; andan optical receiving element inside the lumen configured to collect optical radiation through the first or the second aperture during the ablation procedure, the optical radiation indicating characteristics of adjacent tissue during the ablation procedure;wherein the optical receiving element and the optical emitting element are arranged such that there is a spatial offset between the optical receiving element and the optical emitting element along a longitudinal axis of the lumen. |
