Rigi10™ Malleable Penile Prosthesis
Also Known As
Vacuum pump, penis pump, vacuum constriction device (VCD), vacuum therapy device.
Definition
A vacuum erection device (VED), also known as a vacuum pump or penis pump, is an external medical device used to help individuals achieve and maintain an erection. It typically consists of an acrylic cylinder that is placed over the penis and a pump (either manual or battery-operated) that creates a vacuum within the cylinder.¹ This vacuum draws blood into the penis, causing it to become erect. Once an erection is achieved, a constriction ring or band is placed at the base of the penis to maintain the erection by preventing blood from flowing back out. The constriction band can typically be left in place for up to 30 minutes.¹ The primary purpose of a VED is to treat erectile dysfunction (ED), offering a non-invasive option for individuals who may not be suitable for or responsive to other treatments like oral medications.¹
Clinical Context
A vacuum erection device is clinically used for the management of erectile dysfunction (ED) from various causes. It is often recommended for individuals who cannot take, do not respond to, or prefer to avoid oral ED medications.¹ VEDs can be particularly useful for penile rehabilitation, for example, after prostate cancer surgery, to promote blood flow and oxygenation to the penile tissues, which can help maintain nerve function and tissue health, and potentially minimize loss of penis length.¹ User feedback indicates a generally positive sentiment towards VEDs, though proper patient education is essential to ensure safe use and minimize the risk of injury.²
Patient selection criteria often include individuals with organic, psychogenic, or mixed ED. While generally safe, there are some considerations: the erection achieved may feel cold to the touch as the constriction band restricts active blood flow, and the penis might not stand as rigidly erect at the base (hinge effect).¹ The process can also be perceived as awkward or disruptive to sexual spontaneity by some users.¹ Common themes in user experience include efficacy and ease of use, with safety and warnings also noted.²
Expected outcomes include the ability to achieve an erection sufficient for sexual intercourse. Success rates can vary, and some individuals may move on to other therapies if the VED does not meet their expectations or due to the potential downsides mentioned.¹
