  • Publication number: 20140135414
    Abstract: Processes for modifying the viscosity of medically useful polymerizable compositions are described. The processes are carried out by providing an oxygen-free fluid composition comprising one or more polymerizable monomers and subsequently irradiating the composition with a controlled dose of high-energy radiation sufficient to effect a desired viscosity increase. Compositions produced via these process are also disclosed.

  • Patent number: 7442384
    Abstract: Crosslinked compositions formed from water-insoluble copolymers are disclosed. These compositions are copolymers having a bioresorbable region, a hydrophilic region and at least two cross-linkable functional groups per polymer chain. Crosslinking of these polymers can be effected in solution in organic solvents or in solvent-free systems. If crosslinking occurs in a humid environment, a hydrogel will form. If crosslinking occurs in a non-humid environment, a xerogel will form which will form a hydrogel when exposed to a humid environment and the resulting crosslinked materials form hydrogels when exposed to humid environments. These hydrogels are useful as components in medical devices such as implantable prostheses. In addition, such hydrogels are useful as delivery vehicles for therapeutic agents and as scaffolding for tissue engineering applications.

  • Patent number: 6797311
    Abstract: A process for impregnating a porous material with a cross-linkable composition is disclosed. The degree of impregnation and placement of the cross-linkable composition within the pores of the porous material can be controlled very precisely through the use of a pressure differential. The pressure differential is effected through a nonreactive gas, a vacuum, or a combination thereof. Medical devices produced using such a method are also disclosed.

  • Patent number: 5852114
    Abstract: Biodegradable thermoplastic polymer blend compositions are presented in which a first polymer and a second polymer are intimately associated together in a uniform, substantially homogeneous blend. The second polymer of the composition acts to facilitate biodegradation of the composition, and of shaped articles manufactured therefrom, at a rate which is enhanced over that of the most slowly biodegrading individual polymer component of the composition. The composition may further comprise a polysaccharide component, such as a starch component like destructurized starch.
