Knitted fabrics are widely used in surgery for various applications and textile implants including sutures, meshes for hernia repair, artificial ligaments, knitted grafts and filters for oxygenators.

The versatility of Comez knitting machines allows users to create numerous types of textiles that meet the many requirements in terms of strength, flexibility, durability and stability for these articles.

The Comez Acotronic 8B/600 and SNB/EL-800 machines enable the production of hernia meshes with customised designs and countless pore configurations. Depending on the end user’s needs, both 2D and 3D meshes can be realised, in monofilament or other materials. Hernia mesh is used for the treatment of abdominal or inguinal hernias.

Textile ligaments are used for the reconstruction of damaged ligaments located in different parts of the body. These applications require a special knitted texture by using crochet machines such as the Acotronic 8B/600. The layout of the finished product  as well as the dimension can vary based on individual requirements and surgical treatments.

Membrane filters are used in artificial lungs, blood oxygenators and heat exchangers. These fabrics consist of microcapillaries linked by crochet technology. The CT-8B/829 is a specific crochet knitting machine configuration for blood filtration fabrics.

Knitted grafts are made of synthetic materials using artificial textile veins that can be produced in different designs and diameters. © Comez

Knitted grafts are made of synthetic materials using artificial textile veins that can be produced in different designs and diameters for replacing damaged sections of arteries and veins on the Comez DNB/EL-32. A main distinction is between linear and bifurcated knitted grafts.

Comez, based in Cilavegna, Italy, is part of the Swiss Jakob Müller group.
