Abstract: A method of using a catheter assembly for inserting in a fluid filled space in a body includes providing a main body having a first end portion and a second end portion. The first end portion is positioned within the fluid filled space. The second end portion is adjusted to extend outwardly from the fluid filled space when the first end portion is positioned within the fluid filled space. A catheter tip is connected to the second end portion of the main body. The catheter tip includes a housing having a cavity defined therein and a rotating element positioned within the fluid filled space. The rotating element is rotated within the cavity of the housing to impart movement of the first end portion of the main body within the fluid filled space.

Abstract: A computing system is proposed for installation or retrofit in homes or offices. The system easily installs in wall structures without concern for interference with load bearing structures. In its varying embodiments the system provides for audio or video entertainment, security, remote monitoring, and all forms of communications and networking with other computing systems and appliances. The system exploits a menu-driven graphical user interface, a rigid framing mechanism and special ventilation techniques to achieve an unprecedented computing system for integral incorporation within a home and office.
