Poly(vinyl alcohol) (PVA) is one of the hydrogels most often used in biomaterial applications. Because of the presence of excessive hydroxyl groups, PVA contained a significant amount of water. PVA was also claimed to have good mechanical strength. Another hydrogel, poly(2-hydroxyethyl methacrylate) (poly-HEMA), is well known for its excellent biocompatibility. xhe versatile biomedical applications of poly-HEMA are demonstrated by its uses in contact lenses, vitreous humor replacements and suture materials. To explore a new formulation and other usages of these two pol ers, we have copolymerized HEMA with PVA-MA (PVA esterified with maleic anhydride), the preparation and properties of this copolymer are discussed in this article.

Although not as widely used as titanium, tantalum has found a number of applications, e.g. in vascular clips, as a suture and to fabricate flexible stents to prevent arterial collapse. The reader is referred to a paper by J. Black (1994), where the material properties are reviewed, together with... 

Suture materials need to be tested for tensile behavior, that is, ultimate breaking force (N) and extension at break (%), flexibility, creep and resistance to iatrogenic trauma, that is, the suture s ability to withstand mishandling and trauma caused by needle holders during surgery. In the case of resorbable sutures, the rate of biodegradability or resorption also needs to be measured in terms of the rate of strength loss and the rate of mass loss. These two properties do not follow the same decay curve.

The work presented in Section 12.7.1 was limited to one type of suture, size and power, and the suture used was uncoated braided polyester that tended to develop a secure knot in the 1=1 configuration. Tlie previously unknown effects of a change in power, and suture material and size on knot tensile properties were determined in this study. The laser used was one that was conunerdaUy available and generally found in operating theatres.

The characteristics of a large number of synthetic suture materials are described, together with essential suture properties such as tensile strength, knot strength, elasticity, tissue reaction and biodegradabiUty. 

The above characteristics are based on four essential properties of suture materials ...
