  • TOOLS FOR TRANSURETHRAL DEPLOYMENT AND FIXATION OF GRAFT FOR THE MANAGEMENT AND TREATMENT OF URETHRAL STRICTURES
    Publication number: 20230000650
    Abstract: An embodiment in accordance with the present invention provides a device and method for the treatment of urethral stricture. The present invention places and holds a graft at an incised urethral stricture site for 5-21 days, while the graft adherences to the incised urethral stricture site. A device of the present invention includes a delivery component, a graft carrier component, and a removal component. In some embodiments, the delivery and removal components may be combined into the same device. The delivery component, the graft carrier component, and the removal component are all configured to enter and exit the urethra without trauma. A method according to an embodiment of the present invention includes harvesting a graft, loading the graft onto the graft carrier component, introducing the delivery device into the urethra with the graft carrier component and graft loaded, and delivering of the graft to the incised urethral stricture site.
