Abstract
A catheter placement device is provided which includes a catheter, a pair of relatively rotatable valve members connected to the catheter, an elastomeric longitudinally extending tubular member connected between the valve members and twistable in response to relative rotation of the valve members, and an introducer needle extending longitudinally through the tubular member and catheter for introducing the distal end of the catheter into a blood vessel. Predetermined relative rotation between the valve members effects twisting of the tubular member about the needle and closure of the tubular member. A side port may be connected to a valve member for introducing fluid into a patient.
