Layered high density electrode mapping catheter

A flexible catheter tip, comprising:

• an inboard understructure that defines a tip longitudinal axis, wherein the inboard understructure is formed from a first continuous element that includes a first rectangular cross-section, the first continuous element defining first and second inboard arm understructures and a flared head portion connected to a distal end of each of the first and second inboard arm understructures;
• an intermediate inboard covering disposed about the flared head portion;
• an outboard understructure that extends along the tip longitudinal axis, wherein the outboard understructure is formed from a second continuous element that includes a second rectangular cross-section, the second continuous element defining first and second outboard arm understructures and a head portion connected to a distal end of each of the first and second outboard arm understructures;
• an intermediate outboard covering disposed about the second continuous element that forms the head portion;
• an inboard covering disposed about the intermediate inboard covering and the flared head portion;
• and
• an outboard covering disposed about the intermediate outboard covering and the head portion, wherein the intermediate inboard and outboard coverings and the inboard and outboard coverings are non-conductive coverings and each of the intermediate inboard and outboard coverings and the inboard and outboard coverings extend about a respective circumference of a respective on of the inboard understructure and the outboard understructure.
