  • Publication number: 20110008442
    Abstract: The present invention includes a hydrogel and a method of making a porous hydrogel by preparing an aqueous mixture of an uncrosslinked polymer and a crystallizable molecule; casting the mixture into a vessel; allowing the cast mixture to dry to form an amorphous hydrogel film; seeding the cast mixture with a seed crystal of the crystallizable molecule; growing the crystallizable molecule into a crystal structure within the uncrosslinked polymer; crosslinking the polymer around the crystal structure under conditions in which the crystal structure within the crosslinked polymer is maintained; and dissolving the crystals within the crosslinked polymer to form the porous hydrogel.

  • Patent number: 6696575
    Abstract: The subject matter of the present invention includes a novel biodegradable conducting polymer for biomedical applications. The polymer combines mixed heteroaromatic conductive segments of pyrrole and thiophene with flexible aliphatic chains via degradable ester linkages. In addition to its utility for peripheral nerve regeneration, the polymer may be applied to other areas of tissue engineering, including spinal cord regeneration, wound healing, bone repair, muscle tissue stimulation, and other regenerative, restorative, reconstructive, therapeutic, prophylactic, and diagnostic functions.

  • Patent number: 6095148
    Abstract: Methods and support systems are provided for modifying the regeneration, differentiation, or function of cells. In one embodiment, electrically conducting biocompatible polymers may be used alone or in combination with a polymeric support for in vitro nerve cell regeneration, or in vivo to aid in healing nervous tissue defects. The conductive polymers may implanted adjacent to or seeded with nerve cells. Voltage or current is applied to the polymer in a range which induces the desired effect on the cells while not damaging the cells. The methods and systems can be used in a variety of applications to enhance in vivo or in vitro growth or regeneration of nervous tissue.
