Bioabsorbables
Bioabsorbables are popular in micro medical applications, as the materials dissolve or are absorbed by the body, eliminating the need for repeat surgery for their removal.
Many micro medical applications rely on bioabsorbable materials (also called resorbable, bioresorbable, or biodegradable) because the materials dissolve or absorb into the body, eliminating the need for additional surgeries and minimizing concerns about adverse effects.
A successful bioabsorbable product starts with the right material selection, but also addresses other key factors to ensure premium quality and maximum cost-effectiveness. Learn more about our bioabsorbable expertise and capabilities.
