A device for separation and collection of tissue from an effluent stream of tissue and carrier fluid generated in a medical procedure comprises a housing (600) having an upper wall (601a), a lower wall (602a), a circumferential wall (612) extending between the upper wall and lower wall, an inlet aperture (606a) for receiving the effluent stream and an outlet aperture (607a) for discharge of filtered fluid. The housing encloses a filter member (603a) positioned between said upper wall and said lower wall and comprising at least one filter receptacle (615), the upper wall comprising a viewing window (604) for viewing tissue collected in the filter member. The inlet aperture is located beneath the filter member, and the device comprises a fluid pathway (628) for delivering effluent stream received through the inlet aperture into a said filter receptacle from above the filter member. The device can be compact whilst nonetheless allowing visualisation of collected tissue.
