Development of a water-assisted liposuction device

Development of an innovative water-assisted liposuction device for the extraction of human fatty tissue and adipose derived stem cells for approaches in regenerative medicine, dermatology and reconstructive surgery


The method of water-assisted liposuction (WAL) is capable of gentle extraction of human fatty tissue with the use of a specifically U-shaped water jet. Associated with it is the obtention of adipose derived stem cells (ADSC). A novel WAL-device with compact dimensions for the gently extraction of small quantities of ADSC for tissue engineering application is investigated. This is done in cooperation with human med AG, Schwerin, Germany.

To support the development, Computer Fluid Dynamics (CFD) simulations of the fat cell movement and stress level are performed.

This project is fundet by Ministry of Economics, Labour and Tourism of Mecklenburg-Vorpommern with financial resources by the European Regional Development Fund.
