Abstract: Flexible catheters adapted to be inserted into a body to deliver high-voltage, fast (e.g., microsecond, sub-microsecond, nanosecond, picosecond, etc.) electrical energy to target tissue may include a plurality of conductive layers, that may be coaxial. These catheters and method of using them to treat tissue are configured to reduce or avoid arcing.

Abstract: A cardiopulmonary by-pass system having a vacuum assisted venous drainage system including a hard-shelled venous reservoir which is closed to atmosphere. The reservoir having a blood inlet for supplying blood removed under negative pressure during operation of the cardiopulmonary by-pass system to the reservoir, a blood outlet for removing blood from the reservoir, and a vacuum inlet for supplying a vacuum to the reservoir. A vacuum supply is also included for providing a predetermined desired vacuum of approximately −70 to −25 mmHG from a house wall vacuum source to the venous reservoir via the vacuum inlet. A patient support unit is also provided for receiving blood from the reservoir blood outlet, treating and returning revitalized removed blood under positive pressure. A vacuum regulator subassembly is also provided for manually setting the predetermined desired vacuum. A valve subassembly is further provided for manually enabling and disabling a vacuum from being supplied to the reservoir.

Abstract: A method and apparatus for applying drywall compound to an irregularity in a wall surface. The drywall compound is formulated to be flowable and placed into an aerosol container with a propellant material. A valve assembly is arranged to allow or prevent fluid flow from the aerosol container. When the valve assembly is opened, the aerosol material expands to force the drywall compound out of the container. A scraper member is arranged on the container to facilitate smoothing of the drywall compound; preferably, the scraper member comprises a scraper edge that is arranged adjacent to an exit opening such that the drywall compound can be dispensed and scraped at the same time.

Abstract: A sanitary meat purge eliminator includes a circular upright wall that loosely fits within the opening of a supporting barrel and an outwardly protruding ledge that supports the device on the barrel top. A transverse wall extending across the upright wall includes a perforated section designed to support prepackaged meat and an adjacent discharge opening. The perforated section and discharge opening are separated by an upright divider.
