Abstract (en)
[origin: WO9204059A1] A surgical device (10) has a first cannula (12) formed to define a first channel (13) and a second cannula (70) positioned substantially within the first channel (13) of the first cannula (12). The second cannula (70) is formed to define a second channel (73). Both the first cannula (12) and the second cannula (70) are attached to a conduit piece (20) that defines a first passageway (30) in fluid communication with the first channel (13) of the first cannula (12) and a second passageway (32) in fluid communication with the second channel (73) of the second cannula (70). A third passageway (34) defined by the conduit piece (20) is in fluid communication with the first channel (13) of the first cannula (12). The second passageway (32) is covered by a seal (80) that permits insertion of an instrument (90) therethrough while limiting undesired fluid flow.
