Peristal® Massager Design

 

The Peristal is specifically engineered to work with the body’s natural mechanics rather than fighting against them. While most rectal inserts are static shapes that the body treats as waste to be expelled, the Peristal's design uses the expulsion reflex (the body's natural response to eject any object from the rectum) to its advantage.

Here is how the specific design elements overcome that reflex:

1. The "Shoulder" and "Waist" Synergy

The most critical feature is the relationship between the Shoulder (the upper bulb) and the Waist (the narrow mid-section).

• The Problem: A standard cylindrical object stretches the rectal walls uniformly, triggering a constant contraction wave (peristalsis) to push it out.

• The Peristal Solution: When the rectum contracts, the muscles grip the narrow Waist. Because the Shoulder is wider and sits above the contraction point, the downward pressure actually helps "seat" the device deeper or holds it in a stable position rather than letting it slide out like a smooth taper would.

2. Utilization of Peristaltic Waves

The "Peristal" name comes from the word "peristalsis" because it is designed trigger rectal peristalsic waves.

• As the rectal walls move in a wave-like motion to eject the device, the alternating "Hips" and "Shoulders" of the device provide anchor points.

• Instead of the wave moving the object toward the exit, the muscle contractions catch on the device's contours. This effectively "locks" the device in the optimal therapeutic zone (near the prostate and pelvic floor) during a contraction.

3. Anatomical "Nesting"

The Head of the device is shaped to nestle into the rectal vault, while the Neck allows for a degree of flexibility.

• By reducing the "bulk" in the areas where the sensory nerves are most sensitive (the sampling zone near the anal canal), the device minimizes the "foreign body" sensation.

• If the body doesn't feel a constant, uniform stretch in the lower rectum, the Sampling Reflex is less likely to stay "active," eventually allowing the muscles to relax around the device.

4. External Stabilization (The Base/Foot)

The Base or Foot acts as an external limit. While the internal contours prevent the device from being easily pushed out, the base prevents it from migrating too far in. This creates a "balanced" state of tension where the device stays perfectly aligned with the prostate even as the internal muscles fluctuate between relaxation and contraction.

Summary of Key Peristal Components

Feature	Mechanical Function	Effect on Expulsion
Waist	Provides a "grip" point for the sphincter	Prevents slipping
Shoulder	Acts as an internal anchor	Counters downward pressure
Hips	Stabilizes the device near the exit	Maintains vertical alignment

 

Summary

The result of the Peristal being "locked" in this therapeutic zone is the generation of blood circulation to the area through involuntary peristaltic waves.  These motions tone the pelvic floor muscles through a natural, passive bio feedback loop.
