摘要: A catheter including an elongate drive shaft having a proximal end and a distal end, an ablation burr disposed at the distal end expandable between a first position and a second position, wherein in the second position has a greater transverse dimension than in the first position. The catheter of the present invention can include a mechanism for positioning the burr eccentrically within a vessel lumen. In this context, expansion means that the burr can ablate a lumen having a larger diameter than the diameter of the lumen of the guide catheter to which the device is advanced.

摘要: A combination gas valve in which means associated with the main diaphragm valve is provided for opening the valve in a stepped manner. The combination valve includes an electromagnetic operator which controls the pressure differential across the main diaphragm valve so as to open and close it. The main valve seat surrounds a concentrically located recessed secondary valve seat. Slidably located on a stem extending from the main diaphragm valve, a secondary valve plate having a plurality of orifices therein is adapted to mate with the secondary valve seat so that initial opening of the main valve allows flow only through the orifices in the secondary valve and further opening of the main valve disengages the secondary valve from its seat, thus allowing full flow. On full flow conditions, a servo regulator provides a regulated output.
