International Classification:

C23C 1402
C23C 1424
C23C 1650

US Classification:

427535

Abstract:

Disclosed is a method and apparatus for effecting glow discharge comprising an elongated electrically conductive glow bar electrode, means for applying a potential to the glow bar electrode, thereby generating ions, means for creating a flow of ions from the glow bar electrode to a second electrode, and a shield situated to block partially the flow of ions between the glow bar electrode and the second electrode, said shield having a plurality of apertures through which ions can flow between the glow bar electrode and the second electrode, each aperture having associated therewith at least one shutter, said shutters being capable of at least partially blocking the flow of ions through the apertures, each shutter individually movable to a plurality of positions to adjust the flow of ions through the apertures.

Abstract:

An apparatus includes a navigational guidewire and a suction device. The navigational guidewire includes a sensing element, an outer member and a conductor. The sensing element is configured to respond to positioning within an electromagnetic field. The conductor extends along the length of the outer member and is in communication with the sensing element. The shaft assembly has an open distal end. The shaft assembly also defines a suction lumen and a guidewire lumen extending through the open distal end. The guidewire lumen is dimensioned to receive the sensing element of the navigational guidewire.
