Abstract

Various embodiments of the present disclosure can include flexible catheter tip. The flexible catheter tip can include an inboard understructure that defines a tip longitudinal axis, wherein the inboard understructure can be formed from a first continuous element that includes a first rectangular cross-section. An intermediate inboard covering can be disposed about the first continuous element that forms a distal portion of the inboard understructure. An outboard understructure can extend along the tip longitudinal axis, wherein the outboard understructure can be formed from a second continuous element that includes a second rectangular cross-section. An intermediate outboard covering can be disposed about the second continuous element that forms a distal portion of the outboard understructure.
