  • FLEXIBLE TISSUE COLLECTION DEVICE
    Publication number: 20210251614
    Abstract: An instrument for collecting tissue from a body cavity includes a hollow tubular body having a tubular wall. The hollow tubular body can collect material from a body cavity in a coring mode or an aspiration mode. The tubular wall defines a passage that extends from a proximal end portion of the tubular body to a distal end portion of the tubular body. A middle section of the tubular body includes an articulating section that allows the middle section to articulate relative to the proximal end portion. The distal end portion includes at least one suction port extending from an outer wall surface to an inner wall surface of the tubular wall. The suction port provides a path of fluid communication between the outer wall surface and the passage for drawing in tissue from a body cavity when the tubular body is connected to a source of negative pressure.
