Secondary lymphedema is a common complication after lymph node removal. For most patients the disease is a lifelong condition involving psychological and physical disabilities.¹ With the exception of symptomatic therapies like compression bandages or massages, very few hospitals offer lymph node transplantation as a causal treatment. The surgery is a serious intervention performed under full anesthesia. Currently, a generally accepted etiologic surgical standard therapy for the treatment of lymphedema does not exist.²


The innovation comprises a scaffold for lymph node fragment transplantation. The scaffold is made of a biodegradable polymer and can be manufactured by using a melt electrospinning process. The surgery involves the following steps : First a healthy lymph node is removed from the patient's body. Subsequently, the tissue is fragmented and the fragments are fixed in the scaffolds using fibrin glue. Finally, the filled scaffolds are transplanted into the affected area.

Kommerzielle Möglichkeiten

The invention represents an alternative to complicated lymph node transplantations. With the inventive bioartificial lymph node technology surgery is performed under local anesthesia taking only one hour instead of six to eight hours. Therefore, the strain on the patients and the costs for this causal treatment can be significantly reduced.


Animal testing performed successfully. Next steps: clinical studies
