Abstract: A medical system for applying negative pressure within a gastrointestinal tract of a subject. The system includes a linearizing element, an elongate tube, and a fluid-tight lumen. The elongate tube includes a longitudinal channel, portals in fluid communication with the channel, and a longitudinal shape-forming wire. The elongate tube has a delivery state when associated with the linearizing element and a coiled state when dissociated therefrom. When the elongate tube is in the coil form, a proximal end of the coil forms a shoulder. At a region of the shoulder, the shape-forming wire is modified. The elongate tube has a first flexure modulus in a coil-radial direction and a second flexure modulus, greater than the first flexure modulus, in a coil-axial direction. The fluid-tight lumen is in fluid communication with the elongate tube and couples to a source of negative pressure.

A rotational orientation of the shape-forming wire relative to the elongate tube is fixed throughout an entire length of the shape-forming wire. The fluid-tight lumen is in fluid communication with the elongate tube, and is adapted to couple to a source of negative pressure and to deliver negative pressure to the elongate tube.

Abstract: A wireless-enabled dissolution instrument calibration system including a vessel module measuring a first set of data related to the calibration of dissolution instrument, an instrument module measuring a second set of data related to the calibration of the dissolution instrument, a data conversion module configured to receive the first and second set of data and convert the data into visual data on a report, and a wireless transceiver coupled to the vessel module, the instrument module, and the data conversion module. The wireless transceiver transmits the first and second set of data to the data conversion module automatically as the first and second set of data is measured. The data conversion module organizes the visual data on the report into spreadsheets and/or tables by the particular measurement and renders the visual data un-editable to safeguard compliance.
