Claim Text:
1. A medical device, comprising: a core member having a proximal region and a distal region; a tubular member disposed over the distal region of the core member; wherein the tubular member has a length and a plurality of slots defined through a side wall of the tubular member, the plurality of slots including a plurality of opposed pairs of slots, each opposed pair of slots comprising a first slot at an axial position on the tubular member and a second slot at the same axial position on the tubular member; a plurality of pairs of beams, each pair of beams including a first beam disposed between a first end of the first slot and a first end of the second slot, and a second beam disposed between a second end of the first slot and a second end of the second slot; wherein at least some of the pairs of beams are offset from a central axis of the tubular member by a distance from the central axis to a plane passing through each of the beams in the pair of beams parallel to the central axis; wherein the distance from the central axis to the plane oscillates along the length of the tubular member; wherein the distance from the central axis to the plane oscillates in accordance with a cosine function; and wherein the distance that the pairs of beams are offset from the central axis is defined by: CD CD MAXOFFSET is the distance that the beams are offset from the central axis, and ANGULAR POSITION is an angle from which a cutting member approaches the central axis of the tubular member to make the second cut.
