ABSTRACT:
A catheter device (20) for taking uncontaminated culture specimens from a patient through an orifice includes an outer catheter (22), an inner catheter (23) disposed within the internal passage (33) of the outer catheter (22) and self-sealing valve means (60) located at a distal end of the outer catheter and remotely actuatable via the inner catheter (23) for selectively sealing the proximal end (31) of the outer catheter (22) to prevent contamination of the aperture (49) employed to obtain a specimen by aspiration.
