Augmentation devices Device

The use of an augmentation device results in an improved heat transfer coefficient, thus reducing exergy destruction due to convective heat transfer however, exergy destruction due to frictional effects may increase. The exergy destruction number Nx is the ratio of the nondimensional exergy destruction number of the augmented system to that of the... 

Polymer-supported Ag nanoparticles have been widely investigated and provide potential applications as catalysts, photonic and electronic sensors, wound dressings, body wall repairs, augmentation devices, tissue scaffolds, and antimicrobial filters [15-22]. For these applications, Ag nanoparticles have to be supported in a biocompatible polymer system [23-26]. The electrospinning technique has often been adopted for the incorporation of Ag nanoparticles into polymer porous media. In this chapter, we review the preparation methods and properties of Ag nanoparticles incorporated into polymeric nanofibers and their applications in the fields of filtration, catalysis, tissue engineering and wound dressing. 

The most common types of soft-tissue implants are (1) sutures and allied augmentation devices (2) percutaneous and cutaneous systems (3) maxillofacial devices (4) ear and eye prostheses (5) space-filling articles and (6) fluid transfer devices. 

Sutures and staples are the most common types of augmentation devices. In recent years, interest in using tapes and adhesives has increased and may continue to do so, should new efficacious systems be developed. 

The design of solid-state actuator systems that can be incorporated into wearable fabric structures is one of growing interests both as a rehabilitation tool and biomechanical augmentation device. The use of TCP fibers that can be incorporated into textile structures as a sensor or actuating device for prosthetic applications has been reviewed previously [148]. 

The goals for a ligament prosthesis or augmentation device must be to provide the necessary mechanical stability to the joint without premature degradation or failure. Table 15.8 provides a summary of mechanical properties for a number of synthetic grafts in comparison with normal ACL tissue.
