Intramesh T1

Non-absorbable intraperitoneal parietal reinforcement implant

Intraperitoneal composite mesh for the repair of ventral hernias and incisional hernias.

Intramesh® T1 is an intraperitoneal composite mesh for parietal reinforcement in ventral hernias and incisional hernias.

The visceral ePTFE side provides a smooth barrier surface designed to minimize adhesions on the mesh. The implant is designed for laparoscopic, robot-assisted, or open IPOM techniques.

Clinical benefits

Dual-sided composite design (PP + ePTFE): parietal mesh side for reliable tissue integration, visceral barrier side to protect intra-abdominal organs

  • Designed for the intraperitoneal IPOM technique: suitable for ventral hernias and incisional hernias
  • Proven technology with extensive clinical follow-up: stable outcomes in terms of recurrence and complications across various studies and registries
  • Macroporous parietal side: promotes secure anchoring and limits mesh shrinkage
  • Wide range of sizes: round, square, and rectangular implants for different defect geometries
  • Clearly defined side orientation: simplifies intraoperative identification and reduces the risk of mesh inversion.

Intramesh® T1 is a dual-sided composite mesh, consisting of a macroporous PP mesh parietal side and a smooth ePTFE visceral side. This combination is intended to meet the requirements of intraperitoneal repair: strong reinforcement of the wall on the parietal side, combined with a barrier surface toward the peritoneal cavity to limit adhesion formation. The clear differentiation of the two sides facilitates intraoperative orientation.

Intramesh® T1 is indicated for intraperitoneal parietal reinforcement in ventral hernias, incisional hernias, and certain selected umbilical hernias. The mesh is used with the IPOM/IPOM-plus technique, generally laparoscopic or robot-assisted, when a reliable barrier surface is required on the visceral side and broad parietal coverage with sufficient overlap is sought.

Intramesh® T1 is placed intraperitoneally, with the PP mesh side facing the abdominal wall and the ePTFE side facing the viscera. After insertion, the mesh is deployed without folds and centered over the defect, with sufficient overlap. Fixation depends on the technique and uses trans-fascial sutures and/or tackers (double-crown technique). As a composite mesh with an anti-adhesive surface, it is not intended to be trimmed, in order to preserve the continuity of the ePTFE barrier layer.

For Intramesh® T1 and similar PP/ePTFE composite meshes, several clinical studies and registry data are available. Prospective series of laparoscopic ventral hernia repair with Intramesh® T1 report satisfactory outcomes, acceptable recurrence rates, and a manageable complication profile (e.g., seromas, infections, chronic pain). Other registry data confirm routine use in various centers with stable long-term results.[1–5]
