Claim 10:
11. A method of assembling a filtered needle assembly (100) comprising:
obtaining:
a needle and connector portion (110);
a filtering needle cap body (250);
a seal plug (300); and
a filter (400);

pushing the seal plug into an open distal end (204) of the filtering needle cap body (250) until the seal plug rests against an annular shoulder (220) at a distal end of a proximal chamber (212) that lies between the annular shoulder and an open proximal end (208) of the filtering needle cap body;
holding the seal plug against the annular shoulder with a holding tool (500) that has an open midline while advancing a distal tip (154) of a hollow needle (150) through the seal plug so that the distal tip of the hollow needle extends beyond a distal end (304) of the seal plug and into the open midline of the holding tool;
removing the holding tool after the distal tip of the hollow needle extends beyond the distal end of the seal plug; and
inserting the filter into the distal end of the filtering needle cap body and securing the filter to the distal end of the filtering needle cap body.
