Biomesh P1
Non-resorbable extraperitoneal abdominal wall reinforcement implant
Polypropylene mesh for femoral, inguinal and ventral abdominal wall reconstructions.
Biomesh® P1 is a medium- to heavyweight monofilament polypropylene mesh for extraperitoneal reinforcement of the abdominal wall. It is designed for the treatment of inguinal hernias (including preformed 3D implants), as well as ventral hernias and large incisional hernias. Its more robust structure provides high mechanical load-bearing capacity, especially for large defects or complex reconstructions.
Clinical benefits
Greater stability: higher weight than Premium® for high mechanical-load situations (e.g., large incisional hernias, complex reconstructions)
- Versatile use: from inguinal hernia repair (including 3D implants) to large ventral hernias and incisional hernias
- Preformed 3D implants for the inguinal region: anatomical shapes that facilitate adaptation to the inguinal canal and may reduce operating time
- Large sizes 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 fixation by suture, staples/clips or adhesive, depending on the chosen surgical approach.
Implant material, stability and design
Biomesh® P1 is a monofilament polypropylene implant of approximately 100 g/m². Compared with lightweight meshes, its structure is more stable and less extensible, which may be advantageous in the presence of large defects or high loads. Despite this higher weight, the mesh remains macroporous to allow adequate tissue integration.
Indications and surgical techniques
Biomesh® P1 is indicated for extraperitoneal reinforcement in repairs of inguinal hernias (including 3D implants), ventral hernias and incisional hernias. In inguinal surgery, Biomesh® P1 can be used with open, laparoscopic or robot-assisted techniques, as can ventral hernias and incisional hernias. Flat implants in different sizes—from 10 × 15 cm to 45 × 45 cm—allow extensive coverage with appropriate overlap.
Handling, 3D implants and fixation
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; the flat implants can be trimmed to fit the defects. Fixation can be performed with sutures, staples or adhesive systems, depending on the size, location of the defect and the technique used. Due to the high stability of the material, careful adaptation and sufficient overlap are essential to ensure durable, low-tension reinforcement.
Clinical experience and combination with other technologies
Biomesh® P1 is part of the well-established medium- to heavyweight polypropylene implants in the portfolio. In studies on adhesive fixation of implants, PP prostheses in this category have been used successfully, with stable outcomes in terms of recurrence and complications. Biomesh® P1 complements lightweight meshes (Premium®) and partially resorbable 4D composite prostheses when high mechanical loads are the priority, for example in large ventral defects, multiply operated abdominal walls or in obese patients.[1]
