Surgical sutures characteristics

Ah these interesting characteristics have led to the development of numerous applications of chitosan and its derivatives not only in biomedicine such as surgical sutures, biodegradable sponges and bandages [143], matrices (in microspheres, microcapsules, membranes and compressed tablets) for the delivery of drugs [147], but also in orthopaedic materials and dentistry [148]. 

Biotextile prostheses and closure products, such as surgical sutures, must have certain physical, mechanical and biological performance characteristics. There is a hierarchy of structure in developing these products, and thus their physical and mechanical performance as well as their chemical stability characteristics can be controlled by engineering the structure at the... 

The next two chapters give details about the materials, both resorbable and nonresorbable, used in surgical sutures (chapters 10 and 11). In addition to the traditional materials used in making sutures and their performance characteristics, new materials, some containing antibacterial agents and proangiogenic factors to accelerate healing, are covered in these discussions. 

The previous chapter provided a general overview of the properties of materials used for surgical sutures and of the desirable characteristics of such materials. This chapter considers absorbable and nonabsorbable materials in greater detail, looking within each category first at natural materials, and second at synthetic materials. In the section on absorbable materials, natural materials reviewed are ... 

Fiber characteristics that should be taken into account for making filters include temperature capability, corrosion resistance (withstand adds, alkalies, solvents, etc.), hydrolysis (humidity levels), dimensional stability, and cost. Among important medical application of fibers, we should mention sutures and filters. Sutures are used to close the wound during surgical operations. Fibers used as sutures can be absorbable or nonabsorbable. The main requirements are that the suture must have only a minimal amount of reaction with the tissue and, in the case of absorption, there must be minimal chemical irritation (Lyman,... 

These low molecular weight copolymers have been found useful in the fabrication of surgical articles, particularly in bioabsorbable coatings for sutures due to their very soft, pliable characteristics. 

These wounds and incisions have been traditionally closed with sutures, staples, or surgical tapes, and more recently, tissue adhesives. An ideal wound closure device should be user friendly, quick, pain free and result in excellent cosmesis, without device removal requirement, and of course be cost-effective [87]. None of the current closure devices possesses all of these requirements. Topical cyanoacrylate tissue adhesives, however, have a number of the characteristics of an ideal wound closure device.
