The Spartan vacuum therapy system is an effective and proven rehabilitation tool for men to use after prostate surgery. Rejoyn has simplified our latest erectile dysfunction pump system, the Spartan Premium Battery Operated Pump, to include only those components necessary for post-surgical rehabilitation. Rehab exercises are critical to your recovery and future sexual health, and we recommend that you create daily erections during the period following prostate surgery. It is not advisable to constrict blood flow with a support ring or be sexually intimate during your recovery. We offer the rehab units to provide you with a lower cost system that is not encumbered with unnecessary components. When you are ready for them, the support rings and loading cone are available for purchase in our online store.
