Abstract
A steerable catheter comprises a flexible tube having a proximal portion and a distal portion and comprising a circumferential wall that defines an elongate lumen between the proximal portion and the distal portion. A pull-wire can extend, in association with the wall, from the proximal portion to the distal portion. A pull-ring can be coupled to the wall at the distal portion such that the pull-ring circumscribes the lumen, and coupled to the pull-wire, such that pulling on the pull-wire bends the distal portion. The pull ring can have (i) a first state in which the pull-ring is elliptical and has a first eccentricity, and (ii) a second state in which the pull-ring is elliptical and has a second eccentricity that is smaller than the first eccentricity. The pull ring can be biased toward the first state, and deformable to the second state. Other embodiments are also described.
