4DVentral / Umbilical

Semi-resorbable parietal reinforcement implant

Partially resorbable extraperitoneal prosthesis for umbilical and small ventral hernias.

4DVentral includes a range of round partially resorbable PP/PLLA implants for extraperitoneal reinforcement of umbilical and small ventral hernias. The implant combines a macroporous architecture with a progressive reduction of the implanted mass over time. It is designed for extraperitoneal positioning and covers typical defects at the umbilicus and anterior abdominal wall.
Composition: composite macroporous monofilament mesh made of polypropylene (PP) and poly-L-lactic acid (PLLA)

Clinical benefits

Partially resorbable PP/PLLA implant with marked shape memory: stable parietal reinforcement with progressive reduction of the implanted mass

  • Designed specifically for umbilical and small ventral hernias: round dimensions for centered extraperitoneal coverage
  • Macroporous structure: promotes tissue integration and facilitates intraoperative control of defect coverage
  • Extraperitoneal application: avoids direct contact of the implant with visceral organs
  • Integrated into the 4D range: proven PP/PLLA technology and consistent handling in the operating room
  • Option compliant with recommendations for frequent small wall defects, when a limited amount of permanent material is preferred.

4DUmbilical is a round, partially resorbable PP/PLLA implant of intermediate weight, specially developed for umbilical and small ventral hernias. A high percentage of PLLA ensures sufficient stability during the early repair phase, before progressive resorption. The macroporous design promotes tissue integration, while the shape memory of the mesh facilitates deployment and centered placement over the umbilical defect.

4DUmbilical is primarily intended for umbilical and small ventral hernias treated via an extraperitoneal approach. Typical indications are primary umbilical hernias and small epigastric defects in adults. The implant is designed for open or minimally invasive extraperitoneal approaches and complements intraperitoneal composite prostheses (e.g. CA.B.S.’Air® Composite, Intramesh® T1) in a graduated wall management strategy.

4DUmbilical is positioned extraperitoneally, most often via an approach centered at the umbilicus or the defect. The implant is deployed to cover the defect with sufficient overlap; the round shapes facilitate centered positioning. Flat variants can be cut, provided the macroporous structure is respected. Fixation depends on the technique (sutures, tacks, glue); for small defects, reduced fixation may be sufficient based on the surgical team’s assessment.

4DUmbilical benefits from data generated with 4D technology and extraperitoneal management of small ventral and umbilical hernias. Clinical data on partially resorbable PP/PLLA implants such as 4DMesh® and 4DVentral® show reliable defect coverage with good comfort and low foreign body sensation, as a large part of the implant is resorbed over time. 4DUmbilical thus complements intraperitoneal composite prostheses like CA.B.S.’Air® Composite or Intramesh® T1 when a partially resorbable extraperitoneal solution is preferred.[1–3]
