Maintaining an Erection Using Vacuum Therapy: The Role of Constriction Rings

Erectile dysfunction (ED) affects many men and can have a significant impact on confidence, relationships, and quality of life. Vacuum erection therapy offers a well-established, drug-free alternative, and constriction rings play a key role in helping maintain the erection once it has been achieved. 

What is a constriction ring?

A constriction ring (also known as a support or pressure ring) is placed at the base of the penis after an erection has been created using a vacuum erection device. Its purpose is to gently reduce venous blood outflow for a limited period of time, helping to maintain the erection for sexual activity.
Constriction rings are an essential accessory for vacuum erection therapy and are intended for use exclusively with compatible vacuum erection systems. Medintim constriction rings are designed specifically for use with:

• Medintim Active3® Erection System
• Medintim Manual® Erection System

They are not designed for standalone use.

Why constriction rings matter in vacuum therapy

For many users, the challenge is not creating an erection, but maintaining it long enough for intimacy. When used correctly as part of vacuum therapy, constriction rings:

• Support the maintenance of a vacuum-assisted erection
• Provide a controlled, non-pharmacological option for Erectile Dysfunction management
• Allow therapy without systematic medication

Correct sizing and proper application are essential for comfort and safety.

Material and sizes

Medintim constriction rings are manufactured from elastic thermoplastic elastomer (TPE), a skin-friendly material suitable for repeated use when cleaned according to the Instructions for Use (IFU). The rings are available in five sizes (9mm to 21mm) to allow individual fitting. Selecting the correct size helps achieve adequate support with the lowest possible pressure and without pain.

How to use a constriction ring with a vacuum erection device

A typical application involves the following steps:

• Placing the constriction ring over the cone of the vacuum erection device
• Creating an erection using the vacuum system
• Sliding the ring onto the base of the penis
• Removing the ring after use

The constriction rings are designed for repeated use and should be cleaned with warm water and mild soap. A pause of at least 60 minutes between applications is recommended.
