摘要: A catheter includes multiple primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes a resistive element located at the working end of the catheter. Separation is maintained between the leads such that each lead can individually receive power. The catheter can include a lumen to accommodate a guide wire or to allow fluid delivery. Energy is applied until the diameter of the hollow anatomical structure is reduced to the point where occlusion is achieved. In one embodiment, a balloon is inflated to place the resistive elements into apposition with a hollow anatomical structure and to occlude the structure before the application of energy. The inflated balloon impairs blood flow and facilitates the infusion of saline, or medication, to the hollow anatomical structure in order to reduce the occurrence of coagulation and to improve the heating of the structure by the catheter.

摘要: One embodiment comprises an apparatus for applying energy to a hollow anatomical structure having an inner wall. The apparatus comprises an elongate shaft having a distal end and a proximal end opposite the distal end; and a capacitive treatment element located near the distal end. The capacitive treatment element is sized for insertion into the hollow anatomical structure and placement near the inner wall. The capacitive treatment element is configured to create an electric field that extends at least partially into the inner wall. Other devices and methods for treatment of hollow anatomical structures are disclosed as well.

摘要: Described herein are devices for reversibly constraining an endoscope. Such devices may comprise: a base positionable proximate a patient; a column extending vertically from the base; an arm extending horizontally from the column; and a clamp coupled to the arm. In some embodiments, the clamp comprises a holder comprising an annular ring defining an endoscope receiving area or a first sidewall and a second sidewall together defining an endoscope receiving area. The holder is transitionable between a first configuration in which the annular ring or the first and second sidewall are configured to set apart from an endoscope in the endoscope receiving area and a second configuration in which the annular ring or the first and second sidewall are configured to clamp the endoscope in the endoscope receiving area.

摘要: Disclosed herein is a system for estimating the concentration of an analyte in a material sample. The system comprises a source of electromagnetic radiation; a detector positioned to detect radiation emitted by the source, so that the source and the detector define an optical path therebetween; and a sample element configured to be positioned in the optical path. The sample element comprises a sample chamber at least partially defined by opposed first and second windows which are substantially transmissive of at least a portion of the radiation emitted by the source, and which define an optical pathlength through the sample element. The sample chamber has an internal volume of less than 2 microliters. When the material sample is positioned in the sample chamber and the sample chamber is positioned in the optical path, the system computes estimated concentrations of the analyte in the material sample. The estimated concentrations deviate from corresponding actual concentrations of the analyte in the material sample by an RMS error of less than 15 mg/dL.
