  • Publication number: 20220096061
    Abstract: A device for collecting a biological sample in a patient includes a collection portion having a first axial end portion and a second axial end portion. The second axial end portion has a collapsed position and an expanded position. The second axial end portion moves in an axial direction relative to the first axial end portion when the second axial end portion moves between the collapsed position and the expanded position. The second axial end portion extends axially into the first axial end portion and has a concave shape when in the collapsed position. The second axial end portion is convex when in the expanded position.

  • Patent number: 11278436
    Abstract: Provided is a ureteral stent including a bladder portion positioned in a bladder of a patient, a kidney portion positioned in a kidney and ureteral passageway of the patient, and one or more tethers coupling the bladder portion to the kidney portion. The ureteral stent allows urine to pass around a blockage, and allows a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state to prevent or minimize urinary reflux, flank pain, blood in the urine, etc., while allowing the bladder portion to move freely in the bladder to prevent the bladder portion from irritating the trigone muscle.

  • Publication number: 20220008187
    Abstract: Provided is a ureteral stent for placement in a bladder, a kidney and a ureteral passageway connecting the bladder and the kidney. The ureteral stent includes a solid bladder portion free of a lumen positionable in the bladder, a tubular kidney portion positionable in the kidney and the ureteral passageway, and a tether connecting the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state. By not having a lumen, the solid bladder portion allows the bladder to have a smaller diameter while maintaining a necessary uncoil force. The smaller diameter also allows the bladder portion to be inserted into a scope alongside a pusher tube, thereby avoiding loading the bladder portion onto a guidewire.

  • Publication number: 20200100922
    Abstract: Provided is a ureteral stent (=50) including a bladder portion (=52) positioned in a bladder of a patient, a kidney portion (=54) positioned in a kidney and ureteral passageway of the patient, and one or more tethers (=56) coupling the bladder portion to the kidney portion.

  • Publication number: 20200077992
    Abstract: A device for collecting a biological sample in an esophagus of a patient includes a swallowable collection portion for collecting a sample at a collection site in the esophagus. A stylet is connected with the collection portion for placing the collection portion into the back of a throat of a patient for swallowing. The device may have a collection portion having a first axial end portion and a second axial end portion. A sleeve is in the first axial end portion. The device may have at least one tissue collecting projection extending from an outer surface of the collection portion; a first side wall of the tissue collecting; a second wall of the tissue collecting projection. A method for collecting a biological sample includes moving the swallowable collection portion with the stylet into the back of a throat of a patient for swallowing.
