Abstract

A medical device configured to navigate through anatomy that may be used as a guidewire, or both. Embodiments may navigate like a guidewire, but once in place, perform many or all of the functions that a catheter may perform. The device generally has a body which may be nitinol, with a plurality of pairs of slots cut into the body to make it more flexible in bending while maintaining adequate torsional stiffness. Each longitudinally adjacent pair may be rotated an angle around the axis from the previous pair, and the angle may be less than 89 degrees and greater than 31 degrees. In some embodiments, the angle may be in the range of 70-90 degrees and the average of the angles, computed over 10 adjacent sets of cuts, may be less than 89 degrees and greater than 70 degrees.
