ABSTRACT A medical irrigation device for alternately introducing fluid into and withdrawing fluid from a body cavity through a conduit includes a container defining a fluid-receiving volume and having an open neck, a filter disposed within the container volume for separation of tissue particles above a predetermined size from fluid introduced from the container into the body, and a cap for interconnecting the open neck and conduit. In an improved irrigation device, the filter consists of an elongated filter element disposed adjacent the open neck and extending within the volume of the container, the filter element being disposed about an axis and defining a filter opening axially aligned with and spaced from the open neck. Application of compressional forces upon the container in directions transverse to the axis of the filter element urges fluid toward and through the filter element substantially free of tissue particles in excess of a predetermined size, to pass through the open neck into the conduit toward the body cavity. Upon release of compressional forces, the container expands to withdraw unfiltered tissue-particle-bearing fluid into the container via the open neck and generally axially within the filter element through the filter opening.
