Selectable seal cannula

A kit for for a surgical cannula, said surgical cannula having a tubular member defining a passageway insertable into a medical patient and a housing member at the proximal end of the tubular member and adapted to receive a member transversely movable across the passageway of the tubular member;

• said kit comprising:
• (a) a movable member mountable to the housing cannula and movable transversely across the passageway, said movable member having a first aperture therein and further having a second aperture therein;
• (b) at least one valve body mountable in at least one of said apertures, said valve body having an opening sized to receive and provide a fluid tight seal around a first medical device;
• and,
• (c) a separate elastomeric valve body for mounting in the housing to provide a fluid tight seal across the cannula passageway when no medical devices are inserted therethrough.

A device for a surgical cannula, said surgical cannula having a tubular member defining a passageway insertable into a medical patient, comprising:

• (a) a housing member mountable to the proximal end of the tubular member, said housing member having a passageway allowing insertion of a medical device therethrough and into said lumen, said housing member further adapted to receive a movable member transversely across said passageway;
• (b) a movable member mountable to the housing member and movable transversely across the passageway;
• (c) a first aperture in said movable member;
• (d) a first valve body mountable in said first aperture, said first valve body having an opening sized to receive and provide a fluid tight seal around a first medical device;
• (e) a second aperture in said movable member sized to receive a second medical device, wherein said movable member is transversely movable across the passageway of the cannula between a first position with said first valve body aligned with the passageway and a second position with the second aperture aligned with the passageway.
