- Subject must be willing and able to give written informed consent.
- Subject must be diagnosed with a ventral or incisional midline hernia.
- Mesh must be placed in the retro-rectus or intraperitoneal plane.
- Subject must be willing to undergo open hernia repair and be able to undergo all other study procedures as outlined in this protocol.
- The use of surgical graft as a bridge repair.
- The subject has more than 4 prior recurrences.
- Subject has a contraindication for the placement of surgical graft.

- Subject is pregnant, breastfeeding or planning on becoming pregnant during the course of the study.
- Subjects with known sensitivity to porcine products.
- Subjects with allergy, history of allergy or hypersensitivity to tetracyclines (including minocycline) or rifamycins (including rifampin).

Group Intervention Description Xen Matrix AB Xen Matrix AB Subjects treated with Xen Matrix AB
- Primary Outcome Measures
Name Time Method Number of Participants With Wound Occurrences Up to 45 Days Post Implantation Up to 45 days post implantation Wound occurrences were defined as surgical site infection, seroma, wound dehiscence, skin necrosis and fistulas requiring intervention.
- Secondary Outcome Measures
Name Time Method Number of Participants With Reoperation Due to Index Hernia Repair 24 months post implantation procedure Number of Participants With Wound Occurrences > 45 Days Post Implantation Day 45 and up to 2 years post implantation Wound occurrences was defined as surgical site infection, seroma, wound dehiscence, skin necrosis and fistulas requiring intervention.
Number of Participants With Hernia Recurrence Within 6 Months and 24 Months of Implantation Procedure Within 6 months and 24 months of implantation procedure General Health Score on the Short Form 12 (SF-12) Questionnaire at Baseline, 1, 3, 6, 12, 18, and 24 Months Post Implantation. Baseline, 1, 3, 6, 12, 18, and 24 months post implantation The Short Form 12 (SF-12) is a self-reported 12-item questionnaire that evaluates general health and well-being (overall quality of life of an individual). The SF-12 includes questions on physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. Scores range from 0 to 100, with higher scores indicating better levels of functioning.
Total Score on the Carolinas Comfort Scale (CCS) at Baseline, 1, 3, 6, 12, 18, and 24 Months Post Implantation Procedure Baseline, 1, 3, 6, 12, 18, and 24 months post implantation procedure The Carolinas Comfort Scale (CCS) quality of life questionnaire aimed for patients who have had hernia repair surgery. Symptoms in the CCS are rated by the participants on a scale of 0 to 5, with a score of 0 suggesting no symptoms and a score of 5, disabling symptoms. A lower score on the questionnaire compared to baseline would indicate a better outcome.
Number of Participants Who Returned to Work Post Implantation Procedure Up to 2 years following implantation procedure Duration of Participants Stay in Hospital Following Implantation Procedure From index procedure day to discharge from hospital day
