Abstract
Medical devices, methods of manufacturing medical devices, and systems comprising medical devices are provided. The medical device comprises a shaft having a proximal end, a distal end, and a major lumen disposed therein extending between the proximal end and the distal end. The major lumen is configured to receive a second medical device therein. The shaft comprises an inner liner, a generally planar element wrapped in a spiral pattern about the outer surface of the inner liner, and an outer layer. The generally planar element has a longitudinal axis and a plurality of longitudinally extending ribs and comprises a polymeric material.

A deflectable medical device, comprising:
- a shaft having a proximal end, a distal end, and a major lumen disposed therein extending between the proximal end and the distal end and configured to receive a second medical device therein, the shaft further comprising:
- an inner liner having an inner surface and an outer surface, the inner surface forming the major lumen;
- a generally planar element wrapped in a spiral pattern about the outer surface of the inner liner, wherein the generally planar element has a longitudinal axis and a plurality of longitudinally extending ribs and comprises a polymeric material;
- an outer layer comprising a polymeric material, wherein at least a portion of the outer layer is adjacent the outer surface of the inner liner;
- and,
- an electrode mounted on the outer layer of the shaft, wherein an electrical wire connected to the electrode is disposed within one of the plurality of ribs of the generally planar element
- wherein the inner liner has a plurality of minor lumens disposed therein.
