Abstract: A protective cap for fluidly sealing a connector of a cable is provided. The protective cap includes a flexible body having an interior cavity with a distal opening through which the connector is inserted. The distal opening is defined by an annular ridge that engages a cable portion proximal the connector to fluidly seal the entire connector within the cavity. The body portion may have an oval-shaped cross-section while the interior cavity is cylindrical so that the portions wider portions of the body provide longitudinal rigidity to facilitate installation and removal of the cap by a manual pushing and pulling. A tether may be included to attach the cap to a distal portion of the cable. The protective cap and tether may be integrally formed of a soft, highly flexible material to improve ease of use, biocompatibility and patient comfort.
