1. An ablation catheter comprising:
a proximal section;
a distal section comprising:
an active area, wherein a surface of the active area comprises a patterned texture and is configured to apply radiofrequency (RF) energy, cryogenic cooling, or laser energy output to a portion of a target tissue, such that the portion of the target tissue is ablated; and
a plurality of view ports surrounded by the patterned texture, the plurality of view ports being configured to send and receive optical signals to and from the target tissue; and
a sheath coupled between the proximal section and the distal section, wherein the patterned texture is configured to increase a friction coefficient of contact between the target tissue and the active area, maintain contact between the target tissue and the active area, and prevent movement of the target tissue relative to the active area during a time of an ablation procedure.
