Fat grafting is only as good as the fat that goes in, and ExaFat is Advanced Biomedical Concept’s answer to that problem. This article explains the idea behind it in general terms. It is educational information, not a substitute for the device instructions for use or clinical judgement.

The problem ExaFat addresses

Harvested fat (lipoaspirate) contains not just useful fat and its regenerative cells but also blood, oil and cellular debris. If those contaminants are grafted along with the fat, they can trigger inflammation and unpredictable resorption — a core reason fat grafting results vary.

The fat dialysis idea

ExaFat is built around a fat dialysis concept: cleaning the lipoaspirate to remove contaminants while aiming to preserve the fat’s structure and its regenerative stromal vascular fraction. The goal is cleaner, better-preserved fat that behaves more predictably once grafted.

Why preservation matters

Aggressive processing can remove contaminants but damage the fat and its regenerative cells. The engineering challenge is to clean gently — separating what you do not want while keeping what makes grafted fat take and endure. That balance is the point of a purpose-built system.

Where it fits in reconstruction

Cleaner fat supports the soft-tissue refinement that modern reconstruction relies on, especially in prepectoral reconstruction where the implant sits closer to the skin. ExaFat is often paired with the ExaShape matrix as part of a combined med-tech approach.

The bottom line

ExaFat aims to make fat grafting more predictable by cleaning lipoaspirate while preserving its regenerative fraction — addressing the quality problem at the heart of variable grafting results. See combining ExaShape and ExaFat for how the two work together.
