Comparative Study of Biologic Mesh Versus Repair With Component Separation.

Inclusion Criteria: 1. Is an adult ≥ 18 years old of either gender 2. Will undergo a planned open abdominal incisional hernia repair 3. Has a defect that can be repaired primarily without tension with myofascial advancement flaps and requires no more than 1 piece of surgical mesh (largest mesh size (19 x 35 cm) 4. Contamination is known preoperatively, e.g. repair in the presence of a chronic wound, the presence of a stoma or in conjunction with a bowel resection, or such contaminations occurs intraoperatively, e.g. inadvertent enterotomy or opening of other hollow intra-abdominal viscus 5. Infection is known due to local frank signs of incisional drainage, fistula formation or abdominal abscess following prior surgical abdominal surgery or presence of infected mesh 6. Has an estimated hernia size of ≥ 3cm to 20cm in maximal width by physical exam 7. Is considered a clean-contaminated or contaminated case per Surgical Site Infection Risk Guidelines 8. Is willing and able to return for all scheduled and required study visits 9. Is willing and able to provide written informed consent for study participation Exclusion Criteria: 1. Has a defect that the surgeon cannot achieve primary fascial apposition and requires a bridge of mesh 2. Is a clean or dirty case per Surgical Site Infection Risk Guidelines 3. Has conditions that would adversely affect subject safety as per product labeling 4. Will undergo a laparoscopic hernia repair 5. Has a nidus of chronic colonization, such as chronic indwelling bladder catheter or significant amounts of non-removable infected mesh 6. Has conditions which preclude abdominal imaging at a standard imaging facility 7. Has an anticipated survival of \< 24 months 8. Care plan is to perform a staged repair over 45 days 9. Is bedridden or otherwise non-ambulatory (i.e. is unable to independently transfer into and out of a wheelchair) 10. Is ASA class 4 or 5 11. BMI over 45 12. Is pregnant
