A medical device for the diagnosis or treatment of tissue in a body and method for fabricating the same are provided. The device includes comprises a first shaft and a second shaft. The first shaft includes a longitudinal axis, and the second shaft includes a second shaft axial end disposed within the first shaft. The second shaft is connected to the first shaft by a first nested lap joint formed between the first shaft and the second shaft.

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.

Deflectable catheter shaft section

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.

Elongate medical device including chamfered ring electrode and variable shaft

A system for application of neurostimulation includes an outer sheath, an elongate inner member in the outer sheath and movable relative to the outer sheath. The inner lumen has a distal end. An expandable member is coupled to the distal end of the inner member and is in the outer sheath. The expandable member is self-expanding upon from a compressed state in the outer sheath to an expanded state out of the outer sheath. The expandable member includes a distal portion including a plurality of wires woven together and a proximal portion including the plurality of wires extending parallel to a longitudinal axis. The system includes a plurality of electrode assemblies outward of the expandable member and circumferentially spaced around the expandable member. Each electrode assembly is coupled to two of the wires extending parallel to the longitudinal axis. Each electrode assembly includes a plurality of longitudinally-spaced electrodes.
