Abstract: A steerable catheter includes a catheter shaft having a lumen defined by a catheter wall, a proximal portion, a distal portion, and a length extending therebetween, and at least one pullwire extending along the length of the catheter shaft and coupled to the catheter wall. The at least one pullwire has a proximal section extending along the proximal portion of the catheter shaft in a first radial position, a distal section extending along the distal portion of the catheter shaft in a second radial position, and a transition zone connecting the proximal section and the distal section. The second radial position is offset circumferentially from the first radial position.
