Biomesh P1

Non-absorbable extraperitoneal parietal reinforcement implant

Polypropylene mesh for femoral, inguinal, and ventral wall reconstructions.

Biomesh® P1 is a medium- to heavyweight monofilament polypropylene mesh for extraperitoneal reinforcement of the abdominal wall. It is designed for the management of inguinal hernias (including with preformed 3D implants) as well as ventral hernias and large incisional hernias. Its more robust structure provides significant mechanical load capacity, particularly for large defects or complex reconstructions.

Clinical benefits

Increased stability: higher weight than Premium® for situations with high mechanical stress (e.g. large incisional hernias, complex reconstructions)

  • Versatile use: from inguinal hernia repair (including with 3D implants) to large ventral hernias and incisional hernias
  • Preformed 3D implants for the inguinal region: anatomical shapes facilitating adaptation to the inguinal canal and potentially reducing operative time
  • Large dimensions for ventral hernias: meshes up to 45 × 45 cm for generous overlap of extensive defects
  • Proven PP material with a well-known long-term profile
  • Compatible with suture, staple/clip, or glue fixation, depending on the chosen operative concept.

Biomesh® P1 is a monofilament polypropylene implant of approximately 100 g/m². Compared to lightweight meshes, its structure is more stable and less extensible, which can be advantageous in the presence of large defects or those subject to high stress. Despite this higher weight, the mesh remains macroporous to allow adequate tissue integration.

Biomesh® P1 is indicated for extraperitoneal reinforcement during inguinal hernia repairs (including with 3D implants), ventral hernias, and incisional hernias. In inguinal surgery, Biomesh® P1 can be used with open, laparoscopic, or robot-assisted techniques, as well as for ventral hernias and incisional hernias. Flat implants of various sizes – from 10 × 15 cm up to 45 × 45 cm – allow extensive coverage with adequate overlap.

Biomesh® P1 is available as flat implants and preformed 3D implants for the inguinal region. The 3D prostheses are positioned anatomically on the inguinal floor and fixed at defined points; flat implants can be trimmed to fit defects. Fixation can be performed with sutures, staples, or glue systems, depending on the size, location of the defect, and technique used. Due to the high stability of the material, careful adaptation and sufficient overlap are essential to ensure durable, low-tension reinforcement.

Biomesh® P1 is part of the well-established medium- to heavyweight polypropylene implants in the portfolio. In studies on implant fixation with glue, PP prostheses in this category have been used successfully, with stable results in terms of recurrence and complications. Biomesh® P1 complements lightweight meshes (Premium®) and partially resorbable 4D composite prostheses when priority is given to significant mechanical stress, for example in cases of large ventral defects, repeatedly operated walls, or in obese patients.[1]
