ABSTRACT:
The rear end of a dual lumen oocyte recovery needle is sealed in a plastics hub by means of two polyurethane seals compressed between the outside of the needle and opposite ends of a bore through the hub. The needle has an outer tube and an inner tube with a suction lumen along its length and which is deformed to provide a flushing lumen between its outside and the inside of the outer tube. A suction tube is joined to the rear end of the needle at the rear end of the hub in communication with the suction lumen. A flushing tube is joined in a side bore opening into the interior of the hub and communicating via a slot in the side of the needle with the flushing lumen.
