Abstract: An elongate medical device shaft may comprise an elongate body and an annular electrode disposed on the elongate body. The annular electrode may define a longitudinal axis and have an outer diameter. The outer diameter may be greater at an axial center of the electrode than at an axial end of the electrode. Additionally or alternatively, the elongate body may comprise three longitudinal sections having three wall thicknesses. The middle wall thickness may be less than the proximal and distal wall thicknesses and the distal wall thickness may be less than the proximal wall thickness. Additionally or alternatively, the shaft may comprise an inner cylindrical structure and an outer tube. The outer tube may comprise a first radial layer and a second radial layer that is radially-outward of the first radial layer, the first radial layer, second radial layer, and inner structure having different stiffnesses.

Abstract: A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis with a distal end and a proximal end. First and second pull wires can extend along the elongated body and can have a proximal end and a distal end. First and second pull wire liners can be disposed over a portion of one of the first and second pull wires, respectively. Each of the first and second pull wires can have a proximal end and a distal end. A first gap can exist between the proximal end of the first pull wire liner and the proximal end of the elongated body and a second gap can exist between the proximal end of the second pull wire liner and the proximal end of the elongated body.

Abstract: A deflectable catheter is disclosed. The deflectable catheter includes a deflectable shaft including a proximal portion and a distal portion, the distal portion of the deflectable shaft including one or more electrodes. The deflectable catheter also includes a pull ring disposed in the distal portion of the deflectable shaft, a first pull wire, and a second pull wire. Both the first pull wire and the second pull wire extend through the proximal portion of the deflectable shaft and a distal end of the first pull wire and a distal end of the second pull wire are coupled to the pull ring. The deflectable catheter also includes a cylindrical braid structure at least partially disposed within the distal portion of the deflectable shaft.
