A catheter and stylet assembly is provided which includes a silicone rubber catheter for insertion into the left ventricle of the heart. A stylet of malleable metal covered by a plastic cover is inserted into the catheter to permit the catheter and stylet to be manually shaped into a desired form before insertion into the patient. The stylet is removable from the catheter after the catheter is in the patient.

Preformable catheter

An irrigation syringe is provided which includes a barrel having an axially extending annular groove open at the proximal end for receiving the connector portion of a resilient compressible syringe bulb in tight frictional fitting relation. The syringe barrel is adapted to receive, instead of the bulb, a plunger having a piston that may be inserted into the barrel to provide a piston-type syringe so that the barrel can be used either with a syringe bulb or a syringe plunger. The inner wall of the groove has a plurality of slots so that if the syringe barrel is employed as a funnel, liquid will flow from the groove into the barrel.

Syringe

A multiple passage tube connector fitting is provided which includes a pair of connectors each having a passage open at one end. The fitting has a single-piece elastomeric tube adapter and plug device having a coupling element for connecting it to the connector. The device includes a tube adapter having a passage through it which is connected by a flexible strap to the coupling element and is adapted to fit in the passage of the connector. Another plug is connected by a strap to theadapter for closing the adapter passage. The device also has a plug connected to the coupling element by flexible strap for closing the passage of the other connector.
