Renú® CaHA soft tissue filler implant is a sterile, semi-solid, cohesive implant. The semi-sold nature is created by suspending the CaHA particles in a durable high-yield strength thixotropic gel. The aqueous phosphate buffer gel carrier consists of sodium carboxymethylcellulose (NaCMC) and glycerin. The carrier resorbs in vivo, so that the CaHA remains at the site of implantation, providing a scaffold for local tissue infiltration. This cellular infiltrated CaHA scaffold provides the long-term, non-permanent restoration and augmentation. Over time, the tiny micro-particles gradually break down into calcium and phosphate ions that are naturally absorbed by the body.
