A method of modifying a hypotube may include cutting the hypotube with a laser cut pattern, winding the hypotube in a spiral collector, and flowing gas into the spiral collector. Flowing the gas into the spiral collector may include cooling the hypotube. Flowing the gas into the spiral collector may include flowing the gas into the spiral collector at a temperature between 20° C. and 25° C. The gas may include air or inert gas. The method may include holding the hypotube at a height using a bushing, a plurality of collets, and a hypotube clamp. The bushing and plurality of collets may be configured to inhibit sag of the hypotube to be less than 3% of the height. The method may include inhibiting forming fissures in the hypotube. The pattern may include a plurality of patterns each comprising longitudinally-spaced rows. |
