  • Publication number: 20230263372
    Abstract: Described herein are methods for reversibly constraining an endoscope. A method may include positioning an elongate medical device or endoscope in a holder of a clamp. A method may include actuating the holder such that one or more of a first sidewall and a second sidewall of the holder move to a clamped configuration to exert a force on the endoscope. A method may include adjusting a pad of the clamp from a first position to a second position where the pad is in contact with the endoscope in the second position.

  • Patent number: 11672410
    Abstract: 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.

  • Publication number: 20230149020
    Abstract: Described herein are devices and related methods for occluding at least a portion of a bodily lumen during a procedure. In some embodiments, the device includes an inner shaft defining a lumen therethrough and a first aperture; and an outer shaft including a flexible member and defining a lumen therethrough and a second aperture positioned proximally on the outer shaft relative to the flexible member. The inner shaft extends through the lumen of the outer shaft, such that at least a portion of the outer shaft is axially translatable toward and away from the distal portion of the inner shaft. The flexible member is movable between an unexpanded configuration and an expanded configuration when at least a portion of the outer shaft is translated axially toward or away from the distal portion of the inner shaft. In some embodiments, the device and methods are used for endoscopy procedures.

  • Patent number: 10299796
    Abstract: Described herein are endoscopic plicators passed transorally into the stomach and used to plicate stomach tissue by engaging tissue from inside of the stomach and drawing it inwardly. In the disclosed embodiments, the tissue is drawn inwardly into a vacuum chamber, causing sections of serosal tissue on the exterior of the stomach to be positioned facing one another. The disclosed plicators allow the opposed sections of tissue to be moved into contact with one another, and preferably deliver sutures, staples or other means for maintaining contact between the tissue sections at least until serosal bonds form between them. Each of these steps may be performed wholly from the inside of the stomach and thus can eliminate the need for any surgical or laparoscopic intervention. After one or more plications is formed, medical devices may be coupled to the plication(s) for retention within the stomach.

  • Publication number: 20070100405
    Abstract: A working end of a catheter includes at least one therapeutic element, such as a resistive heating element, usable to deliver energy for ligating, or reducing the diameter of, a hollow anatomical structure. In certain examples, the catheter includes a lumen to accommodate a guide wire or to allow fluid delivery. In certain embodiments, a balloon is inflated to place resistive element(s) into apposition with a hollow anatomical structure and to occlude the structure. Indexing devices and methods are also disclosed for successively treating portions of the hollow anatomical structure. In certain examples, marks along the catheter shaft provide visual verification to the physician of the relative position of the therapeutic element of the catheter. Embodiments of indexing devices may include pairs of rings and/or hinged arms that move a catheter a desired indexed position between successive treatments.

  • Publication number: 20070016272
    Abstract: 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.

  • Publication number: 20050037384
    Abstract: 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.
