An esophageal delivery system includes features that facilitate the precise positioning of a medical device within the gastrointestinal tract. The system supports indexed positioning without relying solely on endoscopic viewing or external imaging equipment to identify the location of the medical device. A fixation element holds an elongated delivery device at a selected position within the gastrointestinal tract. The medical device is carried at a position that is a fixed and known distance away from the fixation element. Once the fixation element is positioned at a known location, precise positioning of the medical device within the esophagus can be achieved with greater certainty. As an illustration, the fixation element may take the form of a balloon an expandable frame or other device capable of engaging the lower esophageal sphincter (LES) to provide a reference position for a medical device to be placed at a precise distance above the LES.

The invention provides an improved procedure for the precise quantitation of organic oxidants in a solution with hydrogen peroxide in which the peroxide is removed by the addition of catalase to scavenge the same. Surprisingly, the catalase does not affect the organic oxidant, and the procedure can accurately quantitate even minute amounts of the organic oxidant. The inventive method is especially effective in quantitating peracid generated enzymatically, although it can be used for chemically generated organic oxidants.

A system and a method of performing a frameless image-guided biopsy uses imaging, a six-dimensional robotic couch system, a laser guidance system, an optical distance indicator, and a needle control apparatus. A planning CT scan is made of the patient with stereotactic fiduciary markers to localize and produce digitally reconstructed radiographs.

Based on the measuremental input, the computer evaluates the surface profile of the cylindrical object. Exemplary inventive practice may also provide for at least one fixed LVDT providing measurements relating to cylindrical length and / or cylindrical end surface profile (e.g., in terms of axial perpendicularity).
