The invention is devices and methods to treat benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms infections (LUTS). The devices are intra-urethral implants placed in a patient in need thereof by minimally invasive procedures, preferably under local anesthesia in an office environment. The devices are sized and designed for atraumatic insertion and expansion within the urethra to engage and retract enlarged prostatic tissue proximate to the urethra that is leading to adverse symptoms associated with BPH. The methods include steps to deploy the implant devices of the invention using a delivery system of the invention and at target prostatic tissue that is visualized during the procedure and yields a reduction in the symptoms of BPH.

In one example, the present invention is directed to a wound-healing patch including a flexible substrate, at least one wound electrode, at least one guard electrode and at least one return electrode. The guard electrode is positioned between the wound and return electrodes in the electrical path of current traveling between the return and wound electrodes on the surface of the skin, sinking the surface current and force the wound current to travel deeper into the tissue. In the invention, the wound electrode(s) is positioned on a portion of the flexible substrate designed to be placed over wounded tissue and the return electrode is positioned on a portion of the substrate substantially surrounding the wound and guard electrodes and is designed to be placed over healthy tissue.

A method for preparing an electrokinetic element is provided and generally includes providing a porous membrane adapted for use in an electrokinetic pump and encapsulating the porous membrane within a polymer substrate to yield an electrokinetic element base member having the porous membrane encapsulated by the polymer. In one embodiment, the method can include laminating the porous membrane between opposed sheets of a polymer before the step of encapsulating. The method can also include cutting the electrokinetic element base member into a plurality of slices and assembling an electrokinetic infusion pump by inserting a slice into a chamber of the pump.
