The biocompatibility of poly(CPP), poly(TA), and copolymers of CPP SA and CPP TA implanted in the corneas of rabbits was studied. Six weeks after implantation, the cornea remained clear and showed no evidence of corneal edema or neovascularization, indicating biocompatibility of the polymer matrix implant. [Pg.2253]

Also within this category of application is the field of radiation grafting onto pre-existing polymeric substrates. E-beam or gamma sources can be used to initiate grafting onto a range of materials, for example poly(olefin)s, fluoropolymers, and cellulosics. The biocompatibility of poly(olefin)s can be greatly...

Lora et al, did try to enhance the biocompatibility of poly[bis(trifluoroethoxy)-phosphazenes] (PTFP) and poly[bis(phenoxy)phosphazenes] (PPP) by grafting different side groups on the polymer surface (Figpme 28). Graft copolymerization w ith dimethylaminoethylmethacrylate (DMAEM) onto the polyphosphazene surfaces highly enhances their biocompatibility. Subsequent heparinization has a negative effect, which is more appreciable with the PPP-based samples (Lora et al., 1991). Surface modification of poly[bis(trifluoroethoxy)phosphazene] with...

Bioerodable materials in current use are limited to applications that do not require long-term strength retention. It is acknowledged by the medical profession that problems exist with the current practices of bone fracture fixation. Two serious problems are osteoporosis due to stress shielding [1-3] and necessary second operations for device removal after bone healing. To alleviate these problems, polymers of a-hydroxy acids such as lactic and glycolic acid are being explored. They have shown potential utility as biocompatible, fully resorbable implant devices. The biocompatibility of poly(a-hydroxy acids) has been known for some time from in vivo acute and subacute tissue reaction [4], as well as in vitro cytotoxicity response [5]. Sutures of these materials have been in use now for many years. [Pg.19]
