A method and apparatus for introducing a stent into a region of a major blood vessel within the human body in a manner which substantially reduces the risk of embolic material escaping to the vessel and causing a blockage at a downstream location. Additionally, the apparatus includes a uniquely designed stent delivery catheter having a central lumen through which a guide wire travels, the central lumen being provided with a valve means that is operable by the guide wire and when moved into a closed position by withdrawal of the guide wire, functions to prevent the flow of loose debris toward the proximal end of the catheter.

An intravascular catheter system includes an intravascular catheter that can be easily and safely navigated through severely occluded arteries. The system uniquely includes both an optical fiber for use in providing data for guiding the catheter and a conventional metal guide wire for use in navigating the catheter through the artery passageway. The system further includes optical imaging of the arterial occlusion during guidance of the catheter through the artery passageway. More particularly the system provides a visual indication to the surgeon to determine if the catheter assembly is approaching the arterial wall.

An apparatus for controllably dispensing fluid, such as eyewash, from a fluid container into the human eye. The apparatus includes a uniquely formed eyecup and a connector connected to the eyecup for securely interconnecting a bottle or vial containing the treating liquid with the eyecup. The connector sealably positions the tip of the liquid containing bottle or vial within the eyecup and at a strategic spaced-apart location relative to the eye being treated.

A wheelchair construction which includes both removable patient foot supports and an outwardly extending patient leg support which can function to support the patient's legs in an upraised position when the foot supports have been removed. The wheelchair construction also includes an easily removable inclined back support assembly having connector elements which are telescopically receivable within upstanding tubular rear members of the wheelchair mainframe for supporting the patient in a more comfortable reclined position. The leg support and inclined back support assemblies permit the wheelchair patient to shift positions and achieve a greater degree of comfort than is provided by the standard wheelchair back and foot supports.
