Technical Information


PosiSep should not be used on patients who have known allergies to shellfish.

Intended Use:

PosiSep Hemostat Dressing/Intranasal Splint is indicated for use in patients undergoing nasal/sinus surgery as a space occupying splint and hemostat to:
• Separate tissue or structures compromised by surgical trauma;
• Separate and prevent adhesions between mucosal surfaces during mesothelial cell regeneration in the nasal cavity;
• Help control minimal bleeding following surgery or trauma;
• Help control minimal bleeding following surgery or nasal trauma by tamponade effect, blood absorption and platelet aggregation; and
• Act as an adjunct to aid in the natural healing process.
PosiSep is indicated for use as a nasal hemostat to treat epistaxis.
PosiSep is intended for use under the direction of a licensed healthcare provider.


Hemostasis, LLC offers two different platforms of hemostat dressings/intranasal splints. PosiSep and PosiSep X are patient-comfortable sponges manufactured from naturally occurring Chitosan polymers. PosiSep and PosiSep X expand when hydrated providing separation between the sinus tissues. However, if extra gelling properties are desired, PosiSep will form a smooth gel surface when exposed to liquids. If extra expansion properties are desired, PosiSep X will expand more than PosiSep to fill in spaces.
