RENU: The Power of Voice

Calcium Hydroxylapatite (CaHA)

for long term management of vocal fold insufficiency

RENU Voice

Sodium Carboxymethylcellulose (Na-CMC)

for short term management of vocal fold insufficiency


The choice for long- or short-term augmentation

RENÚ Voice is for long-term augmentation:

  • A buffered hydrogel with synthetic, proven-biocompatible calcium hydroxylapatite (CaHA) particles 25 to 45 microns in size for consistent and easy injection.1

RENÚ Gel is for short-term augmentation:

  • A buffered hydrogel of sodium carboxymethylcellulose2 (Na-CMC) and glycerin.
  • Resorbs slowly in vivo, providing a scaffold for local tissue infiltration.3

Higher volume, less waste

Both RENÚ Voice and RENÚ Gel provide a greater volume of material than competitive products: 1.5 cc vs. 1.0 cc.1 The greater volume:

  • Helps eliminate waste and inconvenience.
  • Reduces the added cost of opening additional syringes.

Convenience and comfort at your fingertips

Both RENÚ Voice and RENÚ Gel are provided in sterile, ready-to-use 1.5 cc syringes with ergonomic finger grips and 2-year shelf life.

Inject RENÚ Voice or RENÚ Gel percutaneously with a needle of your choice.
