body-jet® neo: The new generation of WAL liposuction

The body-jet® neo has arrived. The new generation of WAL liposuction is now in Spain.

German technology. Over 20 years of clinical experience. And now, a new level of intelligence in the operating theatre.

We have been waiting for this moment for months. Ever since Human Med AG announced the development of the body-jet® neo, we knew its arrival would raise many questions. Both among surgeons already working with WAL technology and among those who have yet to discover it.

And that is exactly what we want to address in this article: what is the body-jet® neo, how does it change the experience in the operating theatre, and why now is the right moment to discover this technology if you have not done so yet.

If this is the first time you hear about WAL, start here

WAL (Water Assisted Liposuction) is a technique developed and refined over more than 20 years by Human Med AG, a German company based in Schwerin and the world leader in the manufacture of medical devices based on water-assisted liposuction.

Unlike conventional tumescent liposuction, the WAL technique does not require waiting for the tissue to infiltrate with large volumes of fluid. The device can be used in three different ways depending on the needs of the procedure:

• ✔ Infiltration only: tissue preparation without aspiration.
• ✔ Aspiration only: when the tissue has already been prepared/infiltrated beforehand.
• ✔ Simultaneous infiltration and aspiration: the most common mode — a pulsating fan-shaped water jet selectively dissolves the adipose tissue while aspirating at the same time.

A fundamental advantage: fat harvested with WAL has high cell viability (≤90%) and can be used directly for lipofilling without the need to wash, clean or centrifuge it. The fat is naturally washed during the process — water enters the system and the aqueous content exits simultaneously — so only a natural decantation is needed to obtain fat ready for transfer. The documented retention rate of the transferred tissue is up to ≤87%.

Other documented clinical advantages:

• ✔ Up to 70% less tumescent solution than in conventional liposuction.
• ✔ Shorter surgical time: no waiting for prior tumescence and with direct selective aspiration.
• ✔ Less trauma to surrounding tissues: blood vessels, nerves and connective tissue are largely preserved.
• ✔ Predictable and reproducible results: the surgeon works on the real body contour, without distortion caused by fluid accumulation.

The body-jet® range is certified with the CE marking (CE 0482) and approved/listed by the FDA (the United States health authority). UpViser Spain is the certified exclusive distributor of Human Med AG in Spain, Portugal and Andorra.

body-jet® neo: the successor to the body-jet® classic

The body-jet® neo is the new WAL device by Human Med AG, launched in 2026, and the direct successor to the body-jet® classic model. The same proven WAL technology. The same working principles. But with a completely redesigned interface, greater efficiency and integrated intelligence that transforms the daily workflow in the operating theatre.

In three words, according to Human Med AG: more intuitive. More efficient. More versatile.

And in figures: +25% pulsation compared to the classic model, while maintaining the same gentle and atraumatic treatment. ≤90% cell viability of the harvested fat. ≤87% retention rate of the transferred tissue.

Over the coming years, the body-jet® neo will progressively replace the classic model as the reference in the range. The transition has already begun.

The intelligent operating theatre: what changes with the neo day to day

The body-jet® neo actively guides the surgical team through the three phases of the procedure:

1. Preparation — guided set-up step by step

The touchscreen guides the team through the set-up, just like the body-jet® evo. Less reliance on the operator’s memory, less margin for error and less waiting time before starting the procedure.

2. Procedure — real-time parameters

All relevant parameters visible on screen simultaneously: water jet (RANGE), aspiration (vacuum), fluid consumption and LipoCollection mode. Full control without interruptions.

3. Documentation — traceability with no additional effort

The body-jet® neo automatically records procedure parameters in a standardised and traceable format. For centres with growing clinical documentation requirements, the neo resolves this with no additional effort.

One platform, three configurations

BASIC — for liposuction

Designed for experienced surgeons who prioritise speed and efficiency. No weighing system, complexity reduced to a minimum.

ALL-IN-ONE for liposuction and lipofilling

With integrated LipoCollection function for the controlled harvesting of high-viability fat, ready for direct transfer. Ideal for aesthetic and reconstructive breast surgery, facial lipofilling, gluteal procedures and regenerative medicine.

ALL-IN-ONE for lipedema treatment

With integrated rack and weighing system (removable, not foldable) for precise monitoring and documentation of tumescent solution volume. Designed for specialist lipedema units.
