Title: Methods and systems for enhancing fluid flow through an obstructed vascular site
Inventor: HANKERMEYER CHRISTINE
IPC: A61F2/958
Filed: 2001-03-06
Abstract: Methods of enhancing fluid flow through a vascular site occupied by a vascular occlusion, as well as systems and kits for use in practicing the same, are provided. In practicing the subject methods, the vascular site is flushed simultaneously with a first dissolution fluid (e.g., an organic matter dissolution fluid and/or an inorganic matter dissolution fluid), and a second dissolution fluid attenuating fluid, where flushing is carried out in a manner such that only a surface of the vascular occlusion is contacted with the non-attenuated dissolution fluid. Examples of dissolution fluid/dissolution fluid attenuating fluid pairs include: (1) oxidizing agent fluid and fluid comprising oxidizable neutralizing agent; (2) surfactant fluid and phosphate buffered saline; (3) acidic solution and phosphate buffered saline; etc.  Flushing is carried out in this manner for a period of time sufficient for fluid flow through the vascular site to be enhanced, e.g. increased or established. The subject methods, systems and kits for practicing the same find use in the treatment of a variety of different vascular diseases characterized by the presence of vascular occlusions, including both partial and total occlusions.

Abstract: Extracts of vetiver oil were found to significantly repel termites. In one extract, nootkatone was isolated and found to be a significant repellent and toxicant of termites. Nootkatone significantly decreased food consumption, decreased tunneling behavior, and increased mortality in termites. Nootkatone is an effective repellent and toxicant of termites either by itself or as an addition to other materials or substrates, including mulches made from vetiver grass roots or other wood products. Nootkatone can also be used to protect construction wood from attack by Formosan subterranean termites. Nootkatone as a repellent is non-toxic to humans and other mammals and is environmentally safe. In addition, .alpha.-cedrene was found to be a weak termite repellent;  and both zizanol and bicyclovetivenol were found to be repellents and toxicants of termites.

Abstract: A precision modulating globe valve for controlling the flow of a fluid from zero to a maximum flow rate. The valve plug of the globe valve includes at least one flow modulating channel recessed from the outer surface of the valve plug. The outer surface of the valve plug engages a sealing member positioned along the inner surface of the valve port. The sealing member provides a fluid-tight seal between the outer surface of the valve plug and the valve port. The flow modulating channel is recessed from the outer surface of the valve plug from a minimum flow end to a maximum flow end. The radially recessed area of the flow modulating channel increases from the minimum flow end to the maximum flow end, such that as the valve plug moves past the stationary sealing member, an increased flow rate is created through the valve port.
