Description: Echo-V is a patent-pending, ultrasound-visible polymer solution that is injected into the vas deferens. It forms a hydrogel device that acts as a semi-permeable membrane, blocking sperm while allowing fluids through. Contraline is designing the gel so that it can be dissolved and flushed out with a reversal solution. Echo-V will be inserted through Vasintomy?, a novel non-surgical procedure.
