Intended Use
MeroPack™ Bioresorbable Nasal Dressing and Sinus Stent is indicated for use in patients undergoing nasal/sinus surgery as a space occupying stent to separate and prevent adhesions between mucosal surfaces during mesothelial cell regeneration in the nasal cavity; to help control minimal bleeding following surgery or nasal trauma by tamponade effect, blood absorption and platelet aggregation; and to prevent lateralization of the middle turbinate during the postoperative period.
Device Story
MeroPack™ is a sterile, bioresorbable nasal dressing and sinus stent; composed of lyophilized, compressed HYAFF® (esterified hyaluronic acid) and collagen. Device functions as a space-occupying stent; placed in nasal cavity by physician post-surgery or trauma. Upon contact with fluids, device acts hygroscopically; absorbs fluid (exceeding 10x its weight) and swells to form a gelatinous mass. This mass provides tamponade to control minimal bleeding; separates mucosal surfaces to prevent adhesions; prevents middle turbinate lateralization. Device degrades over time; absorbed within 14 days or removed via gentle irrigation of residues by physician. Benefits include improved post-operative healing and reduced adhesion formation.
Clinical Evidence
Bench testing only. Data provided includes biocompatibility testing per ISO 10993-1 and FDA Guidance G95-1, and performance characterization (absorption capacity, resorption time). No clinical trials were conducted; substantial equivalence is based on technological and material similarities to legally marketed predicates.
Technological Characteristics
Materials: Esterified hyaluronic acid (HYAFF®) and collagen. Principle: Hygroscopic swelling to form gelatinous mass. Form factor: Lyophilized, compressed stent. Sterilization: Gamma irradiation. Biocompatibility: ISO 10993-1 and FDA Guidance G95-1 compliant. Resorption: Within 14 days.
Indications for Use
Indicated for patients undergoing nasal/sinus surgery or experiencing nasal trauma. Used as a space-occupying stent to prevent mucosal adhesions, control minimal bleeding via tamponade/absorption/platelet aggregation, and prevent middle turbinate lateralization post-operatively.
Regulatory Classification
Identification
An intranasal splint is intended to minimize bleeding and edema and to prevent adhesions between the septum and the nasal cavity. It is placed in the nasal cavity after surgery or trauma. The intranasal splint is constructed from plastic, silicone, or absorbent material.
