ABSTRACT:
An enclosed guidewire exchange system is described which utilizes a flexible sterile barrier which is preferably tubular and folded or rolled prior to use. The barrier functions to enclose the old catheter as it is being withdrawn from the patient. The system also provides a sterile barrier for enclosure of the guidewire upon removal of the old catheter from over the guidewire. Thus, the system preferably includes a guidewire container containing a flexible guidewire. The container includes a connector which may be a threaded female end for attachment to the pilot tube luer of the distal port of the multilumen catheter or other indwelling catheter. The guidewire container preferably includes an interrupted portion such as a window to allow the physician to contact the guidewire within the container so as to advance the guidewire into catheter once the container has been connected to the luer of the catheter. The sterile barrier enclosure is preferably attached to the guidewire container proximal to the female connector and unfolds or unrolls to provide a sterile cavity distal to the guidewire container. The sterile barrier can include a proximal catheter barrier portion and a distal guidewire barrier portion and a tear point or region intermediate those portions. The system may further include a sterile catheter for placement over the guidewire.
