During the procedure, tumescent solution is delivered through the cannula while adipose tissue is aspirated in the same step.

This dual process:

• Reduces the need for high infiltration volumes
• Minimizes tissue swelling
• Improves intraoperative visibility
• Shortens procedure time

The reduced fluid exposure contributes to gentler tissue handling.

Harvested fat is collected in a sterile, closed system such as the LipoCollector® 3 or FillerCollector®.

Key features include:

• Collection of up to 1,000 ml of fat tissue (LipoCollector® 3) 
• Automatic removal of drugs such as local anesthetics and adrenaline 
• Residual fluid reduction to approximately 15% 
• No centrifugation required in many workflows 

This enables immediate preparation for fat transfer.

The WAL procedure typically follows structured phases:

1. Infiltration using gentle water-jet
2. Simultaneous irrigation and aspiration
3. Removal of excess fluid
4. Extraction of injectable fat suspension
   

This systematic approach allows predictable and reproducible results in body contouring and lipofilling applications.

Combined irrigation and aspiration reduces the volume of tumescent fluid required and supports gentler tissue handling.

Moderate suction and selective water-jet power allow controlled fat separation with lower mechanical stress.

Precise separation of adipose tissue helps preserve surrounding structures and supports predictable harvesting.

Continuous irrigation enables improved visual control during the procedure and may reduce correction rates.

Integrated separation of fat and fluid can eliminate the need for centrifugation in standard workflows.

Pressure-adjusted filtration (“swimming filtration”) supports preservation of fat cell structure.
