We describe a new cannula for the intraventricular administration of drugs which is easily and rapidly constructed, is inexpensive and has significant advantages over other cannulas of similar type. The structure of the cannula includes a guiding funnel which greatly facilitates insertion of the injection needle. The cannula also has a locking cap/stylet which is rat-tamper-resistant.
