Patent number: 11278436Abstract: 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.Type: GrantFiled: December 4, 2019Date of Patent: March 22, 2022Assignee: UNIVERSITY HOSPITALS HEALTH SYSTEM, INC.Inventors: Lee E. Ponsky, Dean Secrest

Publication number: 20220008187Abstract: 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.Type: ApplicationFiled: September 23, 2021Publication date: January 13, 2022Inventors: Lee E. Ponsky, Dean Secrest

Publication number: 20200077992Abstract: 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.Type: ApplicationFiled: May 3, 2018Publication date: March 12, 2020Inventors: Sanford Markowitz, Dean Secrest, Amitabh Chak, Joseph Willis, Dennis Siedlak
