Unique Features of the FMS Dilators

FMS stands for Flexibility, Massage, System – a name that already hints at the innovative approach behind these dilators, setting them apart from conventional models. Much of their design draws inspiration from nature:

• The fish-shaped form – with the slimmer end at the back – prevents tissue compression during insertion, unlike wedge-shaped dilators
• The gentle back-and-forth motion of the elliptical head creates a wave-like effect, offering a cramp-relieving massage
• Borosilicate glass, with its exceptionally smooth surface, glides through the body like a fish through water – frictionless and hygienic over the long term

Thanks to their thoughtful construction, FMS dilators are, above all, exceptionally gentle. But they also offer a range of benefits that go well beyond standard use:

• Dilation – not primarily through stretching like conventional conical dilators, but via an alternative, much gentler approach
  
• Massage without irritation – to relieve cramping, gently reawaken scarred or hardened tissue after radiation therapy or birth injuries, and support healthy nerve regeneration
• Haemorrhoid relief – tailored precisely to your individual anatomy and condition
• Prostate massage / stimulation – remarkably effective thanks to the heads’ shape, exceptional glide and precise control
• Heat or cold therapy – from approx. 30 mm diameter upwards, for example warming dilation to relax tight tissue or cooling treatment to soothe haemorrhoids

Philosophy and development of the FMS dilators

The development of FMS dilators was driven by a clear goal: to improve on the weaknesses of conventional conical silicone dilators. Our focus was on gentleness and effectiveness – in line with our philosophy: uncompromising quality.

This commitment to quality explains the outstanding effectiveness of our glass dilators, as confirmed by both clinical application and the consistently positive feedback from users.

Thanks to their unique shape (the effect is concentrated in the front section), FMS dilators can be used in a highly targeted way – for instance, to stimulate the prostate or treat internal scar tissue without having to insert the entire shaft. The slim design avoids unnecessary pressure on the vaginal opening or anal sphincter. The ultra-smooth surface helps prevent irritation of the mucous membranes – during vaginal massage for loosening or stimulation, or prostate massage to support prostate health, potency and erection.

In cases of haemorrhoids, repositioning combined with gentle cooling can often lead to visible improvement after just one use.

1. Innovative shape for gentle insertion

Traditional conical dilators compress the tissue during insertion – the deeper they go, the greater the pressure becomes. The vaginal entrance (or anal sphincter) resists this force, tenses up, and may ultimately only yield to painful pressure. This discomfort, especially caused by the “thick end”, can even trigger retraumatisation.

That’s why we completely reimagined the shape: In contrast to conventional dilators, the active area of our glass dilators is not the base but the head. And instead of a cone, we chose an elliptical head, inspired by nature – the most streamlined shape in water and air. This allows the dilator to glide smoothly into the body, as the tissue can follow the tapering shaft without being compressed. The slender shaft gives the tissue freedom to move in both directions – everything stays in flow.

Moving the dilator gently back and forth generates a soft, wave-like pulsation in the application area – a massage effect. Seven different silhouettes allow for varied stimulation when using multiple dilators from a set. The result: maximum effectiveness with maximum gentleness.

2. Smoothest surface available (ISO 25178)

Materials like silicone or plastic have a relatively rough surface texture, which compromises glide and hygiene. FMS dilators are handcrafted from seamless borosilicate glass – a highly durable material with the smoothest surface of any material in existence.

This enables friction-free use in even the most sensitive or traumatised areas of the body – for example, with inflamed haemorrhoids, after surgery, or during extended massage for flexibility or prostate therapy.

3. 27 sizes for precise personalisation

Most dilator sets on the market include a maximum of 10 sizes – insufficient for the variety of body types, conditions and severity levels that users experience.

That’s why we offer 27 sizes in 1–2 mm increments – the world’s largest range of dilators. Choose from standard sets or create your own, for vaginal or rectal use. This allows you to tailor your set to your body, your health needs (e.g. haemorrhoids grade 1 to 4), or your journey of erotic self-discovery.

We also offer guidance to help you choose the right size or set for your application.

4. Targeted internal applications

With conventional dilators, the widest diameter is at the base, meaning their effect focuses mainly on the vaginal entrance or anal sphincter. This makes targeted treatment of internal areas difficult or even impossible. The pointed shape is also far from ideal for internal use.

That’s exactly what we wanted to change.

In FMS dilators, the effective part is the elliptical head at the front. This offers two clear advantages:
– First, the therapeutic effect no longer depends on how deeply the dilator is inserted, as it does with conical shapes
– Second, internal problem areas can be precisely treated without overstretching the vaginal or anal entrance

The soft head allows for a broad, gentle stimulation or massage, such as of the prostate.

5. Uniform length across all sizes

With conventional silicone dilators, smaller diameters are always shorter – because the material lacks stability.

FMS dilators are made of rigid glass. Even the narrowest sizes are easy to guide and control, so all sizes maintain the same length. This is crucial – especially in the early stages of use – as full-length preparation helps you benefit from the full therapeutic effect.

6. Effective in both directions

FMS dilators are not only effective during insertion – they’re especially powerful during back-and-forth motion. By consciously holding the head in place while moving the shaft, you can train your entire pelvic floor, including vaginal and anal muscles.

Thanks to the ultra-smooth surface, you can gradually increase the movement without irritating sensitive tissue – until the motion gently simulates penetrative sex. This can be a gentle, self-directed way to rebuild comfort with penetration – whether in cases of vaginismus or after a long period of sexual abstinence.

The natural form of FMS dilators – reminiscent of a penis and glans – supports this process intuitively.

7. Sustainable temperature control

From a diameter of 30 mm upwards, FMS dilators have enough internal space to be filled with water-soaked material – allowing them to be warmed or cooled sustainably.
– Gentle warmth supports stretching, massage and can act as a pleasurable erotic stimulus
– Cooling helps reduce swelling and inflammation – ideal for treating haemorrhoids

Further tips are available under vaginal or rectal applications.

8. 100% hygienic, biocompatible and sustainable

Borosilicate glass is not only ultra-stable and smoother than any other material – unlike silicone, it is also completely odourless, stain-resistant, inert and biocompatible. It‘s non-porous surface is easy to clean and meets even clinical hygiene standards with minimal effort.

In contrast to silicone, borosilicate glass is also entirely eco-friendly and long-lasting.

9. Certified medical device

FMS dilators are certified Class I medical devices. Their effectiveness has been verified, and CE certification guarantees their safety and regulatory compliance.

The Fascination of Borosilicate Glass

Borosilicate glass is a truly remarkable material. Engineered to meet the most demanding technical requirements, it is incredibly strong, resistant to extreme temperature shocks, and completely impervious to acids and alkalis.

Our FMS glass dilators far exceed the standard safety requirements defined in the Medical Devices Regulation. You can find detailed specifications, safety certificates and fracture test results in our download section.

At the same time, borosilicate glass possesses captivating optical properties – its unique way of refracting light evokes a sense of sensuality, which is why this material is often used in art and sculpture.
