Abstract
Guards for a space access device are configured to be attached to, as well as removed from the space access device by hand, without the need to resort to any tools to perform the attachment or the removal. A distal guard includes at least first and second filters separated by at least one convoluted pathway, and also includes outwardly extending members projecting outwardly from a base of the distal guard. A proximal guard forms at least one convoluted pathway with a cap forming a proximal end of the space access device. A pull tab provides redundancy against failure. The pull tab may be incorporated into the distal guard.
