The self-venting cannula assembly including an outer tube that defines a throughbore, an inner tube, a vent aperture, and a filter element. The inner tube is positioned within the outer tube, which defines a vent channel therebetween.

The filter element is positioned over the vent aperture and prevents particles having a dimension greater than about 0.2 microns from passing therethrough.
