Clinical Trial Summary

The purpose of this prospective, pivotal, multi-center, single-arm, pre-market, investigational clinical study is to assess the safety and performance of Deternia™ Self-Gripping Resorbable Mesh when used for suture line reinforcement after midline laparotomy in clean and clean-contaminated fields (CDC Classification I and II). Data from this study will be used to support market applications. The indication under investigation is reinforcement of midline laparotomy to limit the rate of incisional hernia (IH) in clean and clean-contaminated surgeries (CDC Classification I and II).

Description:

The primary objective of this investigation is to evaluate the performance of Deternia™ Self-Gripping Resorbable Mesh when used for suture line reinforcement after elective midline laparotomy in clean and clean-contaminated fields (CDC Classification I and II) at 12 months post-operatively and to demonstrate expected performance in terms of rate of IH occurrence relative to a performance goal (based on historical data on primary laparotomy incision suture closure with small bites only). The secondary objectives are to evaluate the safety and performance of Deternia™ Self-Gripping Resorbable Mesh when used for suture line reinforcement after elective midline laparotomy in clean and clean contaminated fields (CDC Classification I and II) within 36 months postoperatively.

11. Study procedure is a relaparotomy within 30 days of previous abdominal surgery

12. Subject with an American Society of Anesthesiologists (ASA) scores higher than 3

13. Subject has participated in an investigational drug study within the washout period of the drug or in a device study that would interfere with mesh implantation or assessment of Incisional Hernia

14. Subject with current chemo and/or radiation therapy within 2 weeks of procedure

Only exclusion of chemotherapeutic drugs that have:

• Cytotoxic effect and/or
• Inhibit of cell replication and/or
• Impaired tissue healing

15. Subject with any history of ascites

16. Subject has a medical condition that precludes the patient from participation in the opinion of the investigator

17. Subject is undergoing a vascular procedure other than abdominal aortic aneurysm (AAA) surgery (i.e, only AAA surgeries accepted) Intraoperative Exclusion criteria

1. Subject's study procedure is in a contaminated or infected site as assessed by the Investigator(s) (CDC Class 3 and 4)

2. Abdomen is left open at the end of the procedure

3. Subject has an unsuspected ventral hernia >2cm encountered at the time of laparotomy

4. Inability to close the anterior fascia or keep the mesh securely out of the peritoneal cavity

5. Second-look procedure planned

6. Cases requiring a full-thickness partial resection of the abdominal wall (in particular the midline) because of involvement in neoplastic process or complex fistula

7. Inoperable tumor/poor prognostic cancer/patient non curatively treated

8. Subject has a suture length to wound length ratio< 3.5/1

9. Subject has any ongoing infection at the time of the surgery, that is uncontrolled and/or requiring treatment such as antibiotics

10. Subject was not implanted with Deternia™ Self Gripping Resorbable Mesh

11. Subject requires more than 1 mesh
