Catheter curve shape struts for steerable medical devices such as catheters are disclosed. These struts may not only help shape a steerable portion of a medical device (e.g., a distal portion of a catheter), but also may help to return a steered or deflected portion of the medical device to an uncurved configuration when it is no longer desirable or necessary to steer or deflect the medical device. These struts may include first and second pluralities of complementary, staggered cutout regions. When used in a catheter that is deployed via an introducer, at least some configurations of the catheter curve shape strut can enable the catheter to be rotated about its longitudinal axis, even when the distal deflectable section is in a curved configuration and inside of the introducer. |
