Patent Images
1. A deflectable tip catheter comprising:
- an elongate catheter body having proximal and distal ends and defining a longitudinal axis;
an inner body coaxially disposed and slideably engaged within the elongate catheter body, the inner body having proximal and distal portions and defining a longitudinal axis, the distal end portion terminating with an atraumatic distal tip, the distal portion including first and second strut members having proximal and distal ends and arranged in spaced apart opposition parallel to the longitudinal axis, wherein the proximal end of the first strut member is cooperatively associated with the proximal portion of the elongate inner body, the distal end of the first strut member is cooperatively associated with the distal end of the second strut member, and the proximal end of the second strut member is cooperatively associated with the distal end of the elongate catheter body; and
a support structure coaxially disposed over the inner body.

Abstract
This invention relates to devices for navigating passageways in a body, and in particular, to a steerable catheter that can be used to navigate the tortuous anatomy of a body'"'"'s vasculature. In one embodiment of the invention the deflectable catheter comprises an inner catheter body having a first strut spine member and a cantilevered second strut tang member. An outer catheter body is cooperatively associated with the second strut tang member and an actuator is cooperatively associated with the first strut spine member. The actuator is slideably engaged within the outer catheter body.
