1. A method of manufacturing an intracardiac blood pump system comprising an elongate catheter defining at least one lumen having a lumen cross section, the method comprising:
coating a filter media with a hydrogel;
assembling the coated filter media to form a self-sealing filter, sized and shaped to have a filter cross section equal to that of the lumen cross section;
positioning the self-sealing filter at a distal end of a sealed compartment;
positioning an elongate catheter such that the self-sealing filter extends between
the sealed compartment and a portion of the elongate catheter, the elongate catheter defining at least one lumen; and
delivering a sterilization gas to the elongate catheter via a hollow tube extending through at least a portion of the sealed compartment.
