The right post-op sinus packing for your patient
Novapak™ Nasal Sinus Packing and Stent is designed to deliver meaningful therapeutic benefits and antibacterial effectiveness to support postoperative healing.1-4
Key features of Novapak™1-8
- Supports vital tissue structures and stabilization at 48 hours
- Dissolves within the nasal cavity with daily irrigation and natural mucus flow
- Absorbs up to 32 times its weight in draining and bleeding of debrided mucosal surfaces
- Acts as a hemostatic aid by absorbing and aggregating blood
- Residence time is typically 7-14 days with adequate irrigation
- Separates and maintains tissue and maintain moisture
- Aids in the prevention of adhesions
- No temperature-controlled environment required for storage or shipping
How Novapak™ works1-4
The Novapak™ sponge is placed in the middle meatus of the nasal cavity and physically separates the mucosal tissue surfaces as a stent and, in turn, aids in preventing adhesion formation. Upon application, Novapak™ acts as a hemostatic aid by minimizing bleeding and oozing of the debrided mucosal surfaces via a tamponade effect, blood absorption, and stimulation of platelet aggregation.
Novapak™ hydrates with sterile saline and forms a gel. The packing dissolves within the nasal cavity with daily irrigation and natural mucus flow over several days. Residence time is typically 7-14 days with adequate irrigation. Alternately, the packing may be removed through gentle aspiration at the discretion of the physician.
Product specifications
Easy-to-use solution with
two configurations
Novapak™ is pliable, compressible, springs back when hydrated, and easily manipulated during placement. One sponge can be used in a bilateral procedure by cutting or tearing. Offered in standard and firm configurations for optimal support, stability and density, enabling surgeons to tailor therapy.1,2

What is chitosan?
Chitosan is a polymer produced from chitin, a component of the hard external shell of shellfish. Its hemostatic properties have been extensively studied in civilian and military clinical settings.1-4
Novapak is contraindicated in patients with known shellfish allergies.
