Abstract
An articulation segment for a catheter includes a tube formed with a first plurality of axially aligned slits that are respectively oriented in planes perpendicular to the axis, with each slit extending azimuthally in an arc partway around the axis. The tube is also formed with a second plurality of similarly formed slits that are axially offset and diametrically opposed relative to the slits of the first plurality to allow for a bending of the catheter in a plurality of different planes. In a particular embodiment, the slits are arranged to allow the articulation segment to be reconfigured from a straight, substantially cylindrically shaped tube to a configuration in which a portion of the articulation segment is formed in the shape of a ring.
