The SomaTherapy-ED SOMAerectStf represents the new generation of uniquely custom fitted vacuum therapy systems for restoring penile health. Utilizing over 25 years of research and development, and manufactured with medical grade plastic, this revolutionary product developed exclusively by Augusta Medical Systems offers 3 cylinder sizing options so you can precisely find the anatomically correct sizing option that neatly fits your fully rigid penis size. The custom sizing technology was developed to ensure that each patient receives the highest level of comfort when treating their ED. Never before has the Vacuum Therapy industry had a product with this level of customization and comfort. The future of vacuum therapy has arrived thanks to Augusta Medical Systems. The custom sizing will prevent the loose non-penile tissue from around the base of the penis (supra-pubic fat or scrotal skin) from being drawn into the mouth of the cylinder during the creation of an erection. The use of the customizable system guarantees a much more comfortable erection experience every time. This system comes with a manually operated negative pressure device that provides effortless operation, you can even operate it with just one finger.
