Implantable devices and methods to treat benign prostate hyperplasia (bph) and associated lower urinary tract symptoms (luts)

A retrievable implant sized and configured for placement in a prostatic urethra narrowed by enlarged tissue and expandable between a collapsed configuration and an expanded configuration comprising:

• a hub having a distal end, a proximal end and a longitudinal axis;
• and
• a plurality of arms connected to the proximal end of the hub, each of the plurality of arms having:
• i) a first curved transitional region connected to the hub, ii) a linear intermediate region connected to the first curved transitional region, the linear intermediate region forming a first angle with the longitudinal axis of the hub when the implant is in the collapsed configuration a second angle with the longitudinal axis of the hub when the arms are deployed outward and the implant is in the expanded configuration, the first angle being greater than the second angle and both the first and second angles being less than 90 degrees, iii) a second curved transitional region connected to the linear intermediate region, and iv) a tissue engaging region that is coaxially aligned with the longitudinal axis of the hub when the implant is in the collapsed configuration and when the arms are deployed outward and the implant is in the expanded configuration, tissue engaging region remains coaxially aligned with the longitudinal axis of the hub and exerts a force on the enlarged tissue in the prostatic urethra in a direction perpendicular to the longitudinal axis.
