16. A tubular member for a medical device formed by the following process;
-
providing a tubular member having a tube center, a longitudinal axis, and an outer diameter; forming a first cut in the tubular member at a first longitudinal position along the longitudinal axis of the tubular member from a first angular position; forming a second cut in the tubular member at the first longitudinal position from a second angular position to define a first pair of slots and a first pair of beams in the tubular member; wherein the first pair of beams is offset from the tube center; forming a third cut in the tubular member at a second longitudinal position along the longitudinal axis of the tubular member from a third angular position; forming a fourth cut in the tubular member at the second longitudinal position from a fourth angular position to define a second pair of slots and a second pair of beams in the tubular member; wherein the second pair of beams is offset from the tube center; wherein the distance that the first pair of beams and the second pair of beams is offset from the tube center is a function of the angular position from which the cut defining the first or second beam pair originates from. - View Dependent Claims (17)
