摘要： A method and means effectively evacuates smoke plumes, vapors, aerosol release, mists, tissue and small particles produced from an operative nasal cavity and any other gas- or air-borne materials provided in or produced in the surgical environment. To this end, an evacuator tube is placed in the contralateral (suction) nasal cavity surrounded by a sealing member which blocks the space between the evacuator tube and nares and/or nasal vestibule.

摘要： A method and apparatus deliver dry, flowable hemostatic powder into a gas flow stream by gravity delivery within a body of the apparatus. The hemostatic powder is then carried with the gas out of the apparatus into an elongated delivery tube inserted into a patient. Delivery of the powder into the gas flow stream creates a bolus of powder and air which becomes more uniformly distributed as it passes through the elongated delivery tube.

摘要： A polymeric stent having a length, an outer surface and a cross-section. A lumen passes through the entire length, the lumen having a surface forming an equivalent diameter in the polymeric stent. The polymeric stent includes a first aqueous-swellable, biocompatible and biodegradable composition (e.g., polymer) having a thickness. The aqueous-swellable and biodegradable polymer retaining structural integrity for at least 1 hours up to thirty days when swollen to between 15% and 500% of its dry diameter and kept moist by a moist aqueous environment. Barrier layers of biodegradable polymer(s) may be used to prevent migration of liquids into the lumen.

摘要： A method and apparatus for the removal of free, emulsified, or dissolved water from liquids of low volatility, such as oil, is shown. The liquid of low volatility is removed by contacting the fluid stream of concern with one side of a semi-permeable membrane. The membrane divides a separation chamber into a feed side into which the stream of fluid is fed, and a permeate side from which the water is removed. The permeate side of the chamber is maintained at a low partial pressure of water through presence of vacuum, or by use of a sweep gas.
