Abstract
An endourethral device is provided having an elongate member having proximal and distal segments, the elongate member positionable within a lower urinary tract so as to at least partially traverses a prostatic urethra. A proximal anchor, adapted to abuttingly engage portions of a bladder neck so as to at least proximally anchor the device, is supported at least indirectly by the proximal segment of said elongate member. The proximal anchor includes bladder engaging elements radially extending from the proximal segment of said elongate member, urine being freely dischargable about at least the proximal segment so as to substantially bathe the bladder neck therewith.
