The support you need with proven hemostatic control
HemoPore bioresorbable nasal dressing delivers the support and stability of our NasoPore dressings—with the added clinical benefits of chitosan lactate, a proven hemostatic agent.
We blended chitosan lactate directly into our proprietary synthetic polymer while preserving the high performance NasoPore has always delivered.1
HemoPore’s gentle to firm compression strength helps prevent adhesions and minimizes edema—while it keeps structures separated and stable. The result for you and your patients: reliable tissue support and hemostatic control without the need for separate topical hemostats.
Stability, control, convenience
- Integrated chitosan lactate hemostat reduces need for topical hemostats
- Supports vital tissue structures for 36 to 48 hours1
- Fragments in 10 to 14 days1
- Helps prevent adhesions
- Clears through natural mucosal flow—no need for manual or painful removal
- No need for mixing, moistening, injection syringes or other prep
Unique two-way action Tissue support plus platelet activation and aggregation
Chitosan Proven to drive the wound healing process3
With proven safety and biocompatibility for human use, chitosan:
- Spurs resting platelets into activation; helping them adhere to collagen4-6
- Fosters platelet aggregation; forming platelet plugs that accelerate blood coagulation4, 6-8
- Has inherent antimicrobial properties9
- Helps avoid the need for direct acting topical hemostats
