STERILE ASPIRATION CATHETER A sterile aspiration catheter is disclosed which includes a catheter tube enclosed within a pliable sleeve and which extends beyond the tube end which is inserted in the patient. Preferably, the sleeve is vented at the end remote from the tube insertion end whereby as the sleeve is retracted from the tube insertion end, air within the envelope escapes through the vent.
