Confirmation of Circulatory Protection from Pacey Cuff
Research News:
The most important contribution made by the invention of the Pacey Cuff male continence device is that the circulation is preserved when the cuff is applied at pressures that are customary for Urethral compression control of urine flow. The development of the cuff was guided by the measurement of blood flow to the glans by use of a hand held digital doppler vascular flow ultrasound. The doppler signal was compared with Classic Clamp designs and found to be variable in older designs that typically have ischemic pain which limits comfort . The Pacey Cuff has consistent pulses with all variants tested during the development and this was particularly so with the low compression Night Cap design of 2018. This variant is designed for night use in combination with an awakening device for extra safety when users take medication to sleep or for pain.

Pulse Oximetry Experiments with the Pacey Cuff
PMT has had the benefit of an engineering co-op 4th year student from the UBC Engineering Physics program during the summer of 2018. Matt Hill , our student, worked with PMT engineering staff Ian Mcdougall and Marc Alphonso of PLC electronics. This has given us many benefits including the development of a testable Pulse Oximetry variant of the Pacey Cuff Turbo device. A very science intensive summer! We also developed the Night Cap device and other products for introduction to the market this fall.

Conclusion:
The Pacey Cuff Urethral Control device does provide excellent protection of the circulation in the penis when normal vascular function and anatomy is present. This confirms the truth of the PMT claim that the circulation is protected.
