Ventral Hernia Study Using OviTex Reinforced Bioscaffold

The study is intended to evaluate the post-operative complications and re-herniations
following the use of OviTex® Permanent 1S reinforced bioscaffold in subjects with ventral
hernias. The study is designed to mirror surgical standard of care for ventral hernia
intervention, with the exception of asking for subjects to return for evaluation at longer
time points post-surgery than is typical for standard care. A baseline visit will be
performed for patients who are identified for and provide informed consent to participate in
the study. During this visit, a review of medical history, a physical exam and assessment of
the hernia site will be performed. The potential subject will also be asked to complete two
quality of life surveys; one that is disease specific and one that is a standard method of
health assessment. On the day of surgery, the ventral hernia will be repaired with the use of
OviTex® 1S reinforced bioscaffold. Perioperative data will be collected and the surgeon will
provide an assessment of the product's handling qualities. During the course of the hospital
stay, the subject will be assessed for incidence of early post-operative surgical site wound
events and complications, all necessary medical interventions and/or re-operations. On the
day of discharge, surgical site occurrences or wound related events noted at the hernia
repair site and the occurrence of other post-operative complications will be assessed.

The Day 30 and Day 90 visits will have a visit window of +/- 2 weeks. At these visits, the
incidence of late surgical site occurrences or wound related events noted at the hernia
repair site will be assessed. If hernia recurrence is suspected, it will be confirmed via
diagnostic imaging with a CT scan. The occurrence of other late post-operative complications
will also be assessed. The subjects will be asked to complete the same disease specific
questionnaire and the same health assessment questionnaire as was done at the Baseline visit,
however the subject will also be asked to complete a pain assessment. Both the surgeon and
the subject will provide an assessment of his/her satisfaction with the hernia repair. The
activities at Months 12 and 24 mirror those of Days 30 and 90, however the visit window is
extended to +/- 4 weeks.

Inclusion Criteria:

with the use of an implant to reinforce or replace weakened or missing tissue.

- The size of the implant needed for repair is expected to be 18 x 22 cm, 20 x 20 cm or
less.

the IRB approved Informed Consent form for this study.

- Subject is able to complete Quality of Life (QoL) and pain Questionnaires.

- Subject has a BMI of >35

- Subject meets CDC/SSI Wound Classification Class III (Contaminated) or Class IV
(Dirty-Infected) criteria.
