Abstract
Disclosed are intravascular devices having enhanced one-beam cut patterns. An elongated member includes a plurality of fenestrations that define a plurality of axially extending beams interspersed between a plurality of circumferentially extending rings. The beams are formed using a dual-pass cutting method in which a blade makes two, rotationally offset cutting passes at a given longitudinal location of the elongated member. The resulting beam has enhanced structure that avoids overly sharp edges and minimizes structural weak points.
Claims18
An intravascular device formed from a stock material, the intravascular device comprising:
- an elongated member extending between a proximal end and a distal end along a longitudinal axis, and having a plurality of fenestrations that define a plurality of axially extending beams and circumferentially extending rings in a one-beam cut pattern, wherein between each pair of adjacent circumferentially extending rings is disposed a single axially extending beam without other axially extending beams;
- wherein at least one beam of the one-beam cut pattern includes an interior surface, an exterior surface, and a pair of lateral surfaces, wherein the lateral surfaces are substantially planar;
- wherein an angle formed between the interior surface and one or both of the lateral surfaces is between about 75 degrees and about 120 degrees;
- wherein an angle formed between the exterior surface and one or both lateral surfaces is greater than about 45 degrees;
- and
- wherein the at least one beam of the one-beam cut pattern has a shape resulting from cutting the stock material to a depth of 30% to 70% of the stock material diameter from a first angle, and cutting the stock material to a depth of 30% to 70% of the stock material diameter from a second angle, wherein the first angle and the second angle are 60 degrees to 120 degrees apart.
