The Rotium™ Bioresorbable Wick is intended to be used in conjunction with suture anchors for the reattachment of tendon to bone in rotator cuff repairs. It is a non-woven, microfiber matrix comprising biodegradable polymer fibers that mimic the extracellular matrix structure. Rotium™ supports cellular infiltration and migration, and facilitates functional tissue regeneration. The Rotium™ Wick is designed to be fully absorbed within 3-4 months over which time it is replaced by neo-native tissue.
Nanofibers act as a scaffold that support cellular ingrowth and proliferation. The Rotium™ Wick supports and encourages the regeneration of healthy tendon and Sharpey fibers.
History Of Rotator Cuff Repair
About 450,000 rotator cuff repairs are performed each year, an increase of 141% in the last decade 
In the last 30 years there have been tooling improvements, but no healing improvements 
Some scaffolds have been used as “onlays” but tendon failure occurs at the insertion point and quality of repair is more important than augmenting the tendon 
“Inlay” scaffolds are currently being investigated, but the four zones of the enthesis are too complex to reproduce in a scaffold 
There is a need to keep the cells at the repair site to promote healing 
Our scaffolds have shown the ability to promote cell migration , localize cells at the repair site , and facilitate remodeling into healthy tissue 
This video shows cells migrating along the scaffold material just as they would in the body. An in-vitro study against a prominent competitor showed that Rotium™ outperformed in cell proliferation and adhesion.
Rotium™ mimics the extracellular matrix found naturally in the body. Our scaffold is engineered to promote healthy tissue growth rather than an inflammatory response - thus decreasing scar tissue formation.
