ABSTRACT:
An angiographic syringe and a connector for effecting the connection of a catheter to the syringe is disclosed. The connector is a tubular member that engages the syringe at the discharge end and removably engages a suitable end member of a catheter. In the preferred embodiment, the connector is a hollow single-piece structure with tabs at one end for engaging the discharge end of the syringe. A track in the discharge end permits purely rotational movement of the connector about the syringe and eliminates any translational movement thereon. The other end of the connector employs an inner thread to engage the corresponding end of the catheter. Rotational movement of the connector about the discharge end of the syringe draws the catheter into tight engagement therewith, eliminating any rotational movement of either the syringe or catheter.
