Abstract: A system comprising: a nasogastric tube comprising: (a) a main lumen having one or more proximal connectors for connecting to a source of substances or pressure; (b) at least four vacuum lumens peripherally surrounding said main lumen; and (c) at least four suction ports for sealingly drawing an inner wall of an esophagus thereagainst, each of said at least four suction ports associated with a different one of said at least four vacuum lumens, wherein said at least four suction ports are distributed between at least two different locations along a longitudinal axis of said nasogastric tube.

Abstract: A method for restricting the number of consequential interactions to further virtual objects having a relationship with a first virtual object, resulting from an interaction with said first virtual object. The method comprises: defining a maximum number of consequential interactions, counting consequential interactions, and stopping further interaction when the maximum number of consequential interactions is reached.

Abstract: A virtual object for use in an object oriented environment; the virtual object comprising at least a user-sensible aspect and further comprising at least a functional aspect; the said user-sensible aspect being encapsulated as a user-sensible encapsulation, separately from the functional aspect, which is encapsulated as a functional encapsulation.

Abstract: Devices and methods for delivering a substance to tissue or organs, particularly, the bladder, by a plurality of microneedles The devices may include a delivery tube, a a substance chamber to fill with the substance to be delivered, a plurality of needles, a plunger coupled to a handle movable relative to the tube to deliver the substance to the tissue through the needles, and a protective plate having at least one orifice therein, such that when the device is in a first, resting, position the needle tips are on a first side of the protective plate, and when the device is in a second, operational, position, the needles are on a second side of the protective plate.

Abstract: A virtual environment for user interaction, and virtual objects for use therein, the virtual objects having an internal co-ordinate system with natural language definition to allow simplified inter-object relationships. The internal co-ordinate system is used to define docking positions for connecting to other objects to allow logical or natural positional relationships. A dynamically defined menu system allows pop-up menus for simple user entry of required relationships.
