Ablation catheter with electrodes

A catheter, comprising:

• an elongate shaft comprising a shaft proximal end and a shaft distal end, the elongate shaft extending along a shaft longitudinal axis;
• a tip assembly that comprises a tip assembly longitudinal axis, wherein the tip assembly is connected to the shaft distal end and includes:
• a proximal electrode portion and a distal electrode portion connected to the proximal electrode portion via an intermediate portion, wherein the proximal, intermediate, and distal portions extend along the tip assembly longitudinal axis;
• and
• an insulative layer disposed on an outer surface of the intermediate portion;
• and
• a mapping electrode disposed on an outer surface of the insulative layer.

A catheter tip assembly, comprising:

• a proximal flexible electrode, wherein the proximal flexible electrode includes at least one first linear gap, configured to allow the proximal flexible electrode to flex;
• an intermediate portion connected to a distal end of the proximal flexible electrode, wherein the intermediate portion includes:
• an insulative layer circumferentially wrapped around an outer surface of the intermediate portion;
• and
• a plurality of mapping electrodes circumferentially disposed on an outer surface of the insulative layer;
• and
• a distal flexible electrode connected to a distal end of the intermediate portion, wherein the distal flexible electrode includes at least one second linear gap, configured to allow the distal flexible electrode to flex.
