Title:
電気伝導性ポリマーを用いる神経刺激
Document Type and Number:
Japanese Patent JP4451929
Kind Code:
B2
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.
