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.

The specification describes new high frequency ion implanted semiconductor devices, novel microwave integrated circuits employing same, and a planar fabrication process for both wherein initially an ion implantation and PN junction passivation mask is formed on one surface of a semiconductor substrate. Next a heavily doped buried region is ion implanted through an opening in the mask and into the substrate to a preselected controlled depth. Thereafter, one or more additional ion implants are made through the mask opening to complete the active device regions and a PN junction therebetween, all of which are bounded by an annular, higher resistivity unimplanted region of the semiconductor substrate. The PN junction thus formed terminates beneath the implantation and passivation mask, and the semiconductor substrate is then annealed to remove ion implantation damage and to electrically activate the ion implanted regions, while simultaneously controlling the lateral movement of the PN junction beneath the passivation mask. Such annealing does not adversely affect the conductivity and passivation characteristics of either the higher resistivity region or the passivation mask.
