Abstract: Methods and apparatus are provided for removing emboli generated during a surgical procedure comprising a catheter having proximal and distal ends, a lumen extending therethrough, an occlusive member affixed to the distal end, and at least one blood intake port disposed in a lateral surface of the catheter. The occlusive member preferably is disposed in a treatment vessel, and the blood intake port, when uncovered, permits a portion of the antegrade flow from a host vessel to be diverted into the lumen of the catheter. A pressure differential caused by the blood intake from the host vessel establishes a venturi-effect suitable for manipulating flow in the treatment vessel. The flow characteristics may be manipulated via the intake port to direct emboli into the lumen of the catheter for subsequent removal.

Abstract: An emboli filtration apparatus is provided comprising a guide wire having a filter element captured thereon, so that the guide wire is free to rotate or translate while the filter element remains stationary. The apparatus allows for movement and rotation of the guide wire as devices are advanced over it to treat occlusive disease, substantially without dislodging the filter element.

Abstract: An engine crankcase oil surveillance system with restoration of oil sufficiency. A vertical oil detection member extends down and into the engine sump. A timer is set for a specific period of time after initiation. The timer is initiated upon shut-off of the engine ignition system. An oil level indicator is activated when said timed period has taken place, and determines the sump oil level. An oil supply means is connected to a reservoir and to the oil level indicator for supplying reserve oil from the reservoir to the sump, upon indication by the oil level indicator that the sump oil level is below a predetermined level. The fluid from the reservoir is cut off the desired oil level is reached.
