ABSTRACT:
Apparatus for central vein cannulation that includes a valved Y-connector for use between a conventional syringe and introducer needle. The valve is in an auxiliary arm and removably receives an end portion of a length of flexible tubing so that venous pressure can be visually observed during the medical procedure and then removed for insertion of a J-wire through the same valve by a conventional J-wire dispensing system.
