A prosthesis for treating a body passage includes a micro-porous tubular element and a support element. The tubular element is formed from a thin-walled sheet having a wall thickness of 25 micrometers or less, preferably a coiled-sheet exhibiting temperature-activated shape memory properties. The mesh pattern includes a plurality of openings in the sheet having a maximum dimension of not more than about 200 micrometers, thereby acting as a filter trapping embolic material while facilitating endothelial growth therethrough. The support element includes a plurality of struts, preferably having a thickness of 100–150 micrometers. The support element is preferably an independent component from the tubular element. Alternatively, the support element may be attached to or integrally formed as part of the tubular element. The tubular and support elements are placed on a catheter in contracted conditions and advanced endoluminally to a treatment location within a body passage. The tubular element is deployed, and the support element is expanded to an enlarged condition at the treatment location to engage an interior surface of the tubular element, thereby securing the tubular element and holding the lumen of the treatment location open.

A sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

A transparent ferrule is fused to an end of an optical fiber to increase the coupling area without altering the input numerical aperture of the fiber system. This is accomplished by controlling the length of the area at which the transparent ferrule is fused or welded. In addition, an extended ferrule portion is situated behind the fusion area and is separated from the fiber core such that light that fails to couple to the core is reflected from the inner diameter of the extended ferrule portion away from the fiber core, where it can be deflected or dissipated by a beam block or absorptive material. The transparent ferrule is formed from a plurality of relative thin wall ferrules that are successively fused from the side to form at the least the termination or coupling end of the transparent ferrule.

The anchor may be a section of the catheter body having an expandable axial cross-section, an expandable member mounted on the catheter body, one or more wire anchors, or a flexible section of the catheter body.

Two identical support cushions are flexibly joined to provide ergonomic support to a person having to perform physical activities in a supine position, often in confined spaces, such as a plumber lying on his back under a sink inside a cabinet with the lower part of the body being positioned on the room floor and the upper part of the body being positioned on the raised floor of the cabinet. The lightweight and rugged support cushions can be easily configured into a valise-like rectangular shape for easy carrying utilizing integrated handles. In addition, a plurality of lamps is enclosed within the support cushion, the lamps comprising light diffusing lenses and the lamps being spatially aligned to provide illumination with minimum shadow creation of the space in front of the supported person, such as a plumber working under a sink in a cabinet.

Heat transfer fins (110), and heat exchangers (100) incorporating such fins (110), enhancing heat transfer with acceptable pressure drop increase. The fins (110) include tabs or secondary fins bent upward and downward from the fin body at a selected bend angle. All or a majority of the tabs are aligned with a simple flow path or with local flow paths for cooling air adjacent the fins (110) to minimize turbulence and pressure drop. The tabs are planar and generally aligned parallel to the simple flow path or local flow paths and are arranged so as to serve as a plurality of sites for starting new boundary layers by offsetting the tabs such that downstream tabs are not shadowed by upstream tabs. The tabs have a height sufficiently large to extend the tabs out into boundary layers on the fin (110). The tabs provide more uniform flow over fins (110) and shrink wake size behind tubes (120).
