Ultrasound welding device for reinforcement of the invasive textile mesh destined to the reconstruction of the thoracic wall

Abstract

The assimilation of synthetic macromolecular compounds in the interdisciplinary fields represented by the medicine and therapeutics, must address the complexity of the problems imposed by the application field, mainly resulting from the temporary or long-term contact of the polymeric materials with the tissues and biological substances. In this context, polymeric biomaterials are defined as polymers or polymeric composite types certified as biocompatible in contact with the biostructures. Comparing to conventional procedures, ultrasonic welding is a domain with a lower overall weight, but with exceptional development and dissemination perspectives in different industrial branches (automotive, electrotechnical, electronics, microelectronics, medical devices), which involves techniques of combining new materials, biocompatible, intelligent composites, with shape memory, etc. Through their geometric, technical, bio functional and biomedical characteristics, the implantable medical devices must meet the imposed requirements, mainly represented by: chemical inertia, resistance to infections, adequate ratio between flexibility and dimensional stability, adaptability to the defect geometry and high bursting resistance etc.
