  • Publication number: 20240216160
    Abstract: Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing tube having a distal end portion including plural apertures through which suction is applied for anchoring the sizing tube in the patient's stomach and for forming a visually perceptible delineation line on the exterior of the patient's stomach along which a portion of the stomach may be resected, sealed and tested. The elongated flexible sizing tube includes a source of illumination to produce near infrared light to facilitate the location of the sizing tube within the patient's stomach and to provide visual information about location of certain relevant internal anatomical features.

  • Publication number: 20240108488
    Abstract: Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing tube having a distal end portion including a plurality of apertures. The control valve enables suction to be applied to the patient's stomach via the apertures to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the sizing tube to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

  • Publication number: 20230414254
    Abstract: A device and method of use for treatment/management of postpartum uterine bleeding or hemorrhage of a patient. The device includes a suction tube having a distal end portion at which an aperture or an array of plural apertures is located and extending about the periphery of the distal portion. A sealing member having a flexible sidewall whose outer surface is of a generally conical, bulbous, or cylindrical shape is mounted on the suction tube and extends distally from the apex of the sealing member so that a portion of its sidewall can be brought into engagement with tissue outside of the uterus. Suction from a vacuum source is applied to a proximal end portion of the suction tube to apply suction via the aperture(s) to the interior of the patient's uterus.

  • Publication number: 20230099821
    Abstract: System and methods for automatically removing by suction urine voided by a female. The systems include an external catheter and an integrated suction regulator or a stand alone external catheter for use with any source of regulated suction. The external catheter includes a suction tube an a fluid pervious cover. The catheter's cover is applied at the female's urethra opening to receive urine voided by the female, whereupon urine from the external female catheter passes through the cover into the suction tube, from which it is carried by out of the external catheter for collection. The external catheter is malleable so that it can be conformed to the anatomy of the female.
