摘要：
An implantable biocompatible expander (1) suitable for implantation into a urinary duct, comprises an elongated sinusoidal ring comprising at least two proximal prongs (7) and at least two distal prongs (5), wherein the expander is resiliently deformable from a relaxed radially expanded orientation to a radially contracted orientation suitable for transluminal delivery through the urinary duct. The expander is configured to exert an outward radial force against a wall of the urinary duct when /n-s/fx/within the urinary duct. In particular, the expander is suitable for treatment of benign prostatic hyperplasia and configured for implantation into the prostatic urethra between, and substantially spanning the prostatic urethra between, the bladder neck and external sphincter.
