1. A needleless connector, comprising:
a housing comprising a cavity and a proximal fluid port in fluid communication with the cavity;
a filter support disposed at least partially within the cavity, the filter support comprising a distal fluid port in fluid communication with the proximal fluid port; and
a filter disposed circumferentially around the filter support and between the proximal fluid port and the distal fluid port, wherein a proximal end of the filter radially expands away from the filter support to prevent fluid flow through a filter medium to the proximal fluid port.
