In 1908, W. S. Handley introduced one of the earliest concepts of artificial lymphatic channels. By implanting sterile silk threads subcutaneously in lymphedematous limbs, he demonstrated temporary improvement of lymphatic drainage and reduction of swelling, attributed to capillary action along the threads.
A preclinical murine study demonstrated that interstitial fluid drainage pathways are essential for lymphangiogenesis and can direct its formation.
Treatment with BioBridge scaffolds, both as a standalone approach and in conjunction with autologous lymph node transfer, has been shown to support lymphangiogenesis.
In a porcine model of induced secondary lymphedema, three months after implantation, the nanofibrillar scaffold demonstrated high biocompatibility, accompanied by substantial cellular infiltration within the scaffold structure. Immunofluorescent analysis revealed a significant increase in the number of lymphatic collectors in close proximity to the scaffold.
This was associated with restoration of lymphatic drainage, reflected by improved bioimpedance measurements and a reduction in tissue fluid accumulation.
Histological analysis of lymphedema sites three months after BioBridge implantation. Arrows indicate the folds of the scaffold integrated into the surrounding tissue. Cellular infiltration is observed throughout the internal structure of the scaffold.
Confocal microscopy images of immunofluorescent staining demonstrate the presence of newly formed lymphatic structures, characterized by LYVE1-positive vessel-like formations with defined lumens.
Changes in the average bioimpedance ratio in treatment and untreated control groups. A reduction in bioimpedance following BioBridge implantation indicates decreased interstitial fluid accumulation at three months post-treatment.
Six out of eight patients treated with BioBridge responded within six months, with an average limb volume reduction of approximately 20%.
BioBridge was associated with greater edema reduction versus controls and increased newly formed lymphatic collectors.
Observational studies demonstrated significantly greater limb volume reduction in the BioBridge group.
