Abstract: A catheter system includes abase plate having a bottom surface, an outer circumferential wall, a circular flange extending inwardly from the outer circumferential wall, and an inner ring that is spaced apart from the outer circumferential wall, extends upwardly from the bottom surface, and defines a central opening in the base plate. A catheter is placed within the central opening of the base plate. A cover is placed over and secured to the base plate. The cover has a closed upper portion defining an internal chamber of the cover and a lower portion defining an opening in the cover. The lower portion includes a skirt with a flange extending outwardly around a periphery of the skirt to engage the circular flange of the base plate and form a closed reservoir. Methods of accessing cerebrospinal fluid using the catheter systems are also provided.

Abstract: A bio-mass fueled boiler operating at delivered efficiencies in excess of 90%. Pre-heated, pressurized primary combustion air is supplied to a primary burn chamber via horizontal and vertical orifice containing conduits. Exhaust gases are directed past a reflective secondary burner supplying pre-heated, pressurized secondary combustion air into a secondary burn/ash collection chamber. Exhaust gases are directed from the secondary burn chamber via exhaust conduits having axial and cross-sectional shapes and wall geometries that promote internal turbulence and heat transfer. One or more gas/oil fired burners are fitted to or between the primary and secondary combustion chambers. Several operating modes are provided via associated blowers, air baffles, liquid and gas fuel conduits, pumps and sundry stove sensors and servos coupled to microprocessor control circuitry.
