ReFilx™ Technology

In collaboration with University of Toronto and the University Health Network, Polumiros Inc. has developed ReFilx™, a Regenerative Filler Matrix, using our immunomodulatory polymer technology, which provides breast cancer patients with a cosmetically superior and minimally-invasive solution for the permanent restoration of breast tissue defects following lumpectomy. 


Lumpectomy, an essential component of most breast cancer treatments, often results in poor cosmetic outcomes due to large soft tissue defects from the procedure. There is an increasing demand for better cosmesis as these patients are expected to survive longer-term, and poor cosmetic outcomes can serve as a constant reminder of their illness, causing psychosocial distress and negatively impacting their quality of life.
