1. An endourethral device comprising:
- a. a proximal anchor adapted to abuttingly engage a bladder neck so as to at least proximally anchor said device, said proximal anchor including a body and bladder engaging elements radially extending therefrom, urine flowable about an exterior surface of said body of a deployed device so as to substantially bathe the bladder neck therewith;
b. a distal anchor adapted to engage portions of a bulbous urethra so as to at least distally anchor said device; and
,c. an elongate member interposed between said proximal and distal anchors, said device being anchorable within a lower urinary tract such that said elongate member at least partially traverses a prostatic urethra.

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.
