Protocol & Research

The lipofilling technique includes four essential steps:

      • Infiltration
      • Tissue harvesting
      • Washing and centrifugation
      • Injection

Tissue preservation is key to its survival. Adip’sculpt instruments, technique and protocols ensure efficient tissue harvesting, while controlling the negative pressure and preserving adipose / Stromal Vascular Fraction (SVF) cells, leading to:

      • Increased retention rates: 70 to 90%
      • Decreased oil release, cyst formation, necrosis, inflammation.

Protocol

Infiltration of the tumescent solution

Pre-tunneling and infiltration of the tumescent solution (avoid local anaesthetic if the patient is under general anaesthesia as it is toxic for the SVF cells) with the provided infiltration cannula will ensure a better diffusion of the solution in the donor site (resulting in greater retention rates of the transferred tissue), as well as making the harvesting easier.

Tissue Harvesting

Cannulas size and design

The size of the harvested lobules affects the fat retention rates, as small adipose lobules ensure a better vascularisation. Adip’sculpt harvesting cannulas have been specifically designed to harvest micro lobules adapted to each indication. The blunt micro cannulas also preserve the integrity of the adipose cells, ensuring their viability.

Negative pressure

High negative pressure damages the adipose cells’ membrane.  A low negative pressure (10 ml in a 60 ml syringe / 2 ml  in a 10 ml syringe) will ensure optimal adipose cells viability. Adip’sculpt developed and patented the 60 ml Spinfill syringes to ensure low pressure thanks to its lockable plunger in 10 ml increments.

Washing and centrifugation

Once harvested, the adipose tissue needs to be purified as it contains cell debris and toxic molecules. To increase the retention, the tissue is washed and leftover solutions removed. Adip’sculpt has shown that centrifugation is the most efficient technique; however, the parameters must be set at a low speed and short duration to concentrate the tissue while preserving cell viability.

Injection

Adip’sculpt fine injection cannulas ensure the deposition of a small amount of adipose tissue per channel, maximising the vascularisation of the transferred tissue and thus ensuring high retention rates.

Studies & research

Comparative study of 4 protocols

Comparative studies (in the same patient) with different techniques have shown that Microfill and Macrofill have greater retention rates than other devices.

Clinical study

A clinical study performed on 23 patients (breast reconstruction after DIEP surgery) with the Macrofill kit have shown fat retention rates >70% (6 months post-surgery).
