Abstract:
A catheter assembly comprises a catheter and a sheath enclosing the catheter to preserve the sterility thereof, the sheath being provided with a plurality of fold lines which form accordion-like pleats to enable a collapse of the sheath at a point of insertion of the catheter into a patient. The sheath is provided at a distal end of the catheter with a flange for engaging a patient during an insertion of the catheter into the patient. A catheter assembly also comprises an anchor balloon attached to the catheter at a distal end thereof, an ancillary balloon attached to the catheter at a point spaced in a proximal direction from the anchor balloon, a tube connecting the ancillary balloon to the anchor balloon so as to enable communication therebetween, and a flow stop mounted to the catheter for preventing fluid from returning to the tube from the anchor balloon upon a pressurization of the anchor balloon with fluid forced from the tube by an application of pressure to the ancillary balloon. A hollow catheter plug defining a flash chamber and having a transparent wall is connected to the catheter at a proximal end thereof for communicating with the catheter. A valve is connected to the plug for preventing fluid flow from the flash chamber.
