#### 7.0 Substantial Equivalence

EpiFilm™ Otologic Lamina is an ENT polymeric implant material for prescription use supplied sterile in individual pouches containing a single 2.5 cm x 2.5 cm square of the device. EpiFilm™ squares feature microholes to provide a permeable surface and are intended for aid in surgical repairs and is an adjunct to aid in the natural healing process in various otologic procedures by providing a biocompatible covering surface.

Both the subject and predicate devices are intended for use as long term implant materials for ENT surgical repairs. Both use biocompatible polymeric materials in the form of thin sheeting which may be trimmed to meet the specific needs of the patient, are sterile, single use. The difference is that the predicate devices are made of silicone whereas EpiFilm™ is made of the benzyl ester of hyaluronic acid which typically dissolves in about six (6) to eight (8) weeks after implantation.

material comprising EpiFilm™ has been subjected to extensive The biocompatibility testing according to the ISO/EN standards for material testing for toxicity and biocompatibility. The material has been demonstrated non-toxic and biocompatible according to ISO 10993 standards, and in clinical study has presented no new issues of safety or effectiveness for the intended use.

In conclusion, Xomed EpiFilm™ Otologic Lamina has the same intended use as the predicate devices and differs only in the material which has been shown as biocompatible, as based on the data in the submission, and raises no new issue of safety or effectiveness.
