ABSTRACT:
Polymeric materials and processes for making the same are provided herein wherein said polymeric materials have nano-sized topological features or textures. These features have dimensions in various ranges including, but not limited to, dimensions less than about 100 nanometers. In addition, polymeric materials are described herein that have a surface roughness of about 50 nm or greater. These polymeric materials are useful for making implants for soft tissues, such as bladder tissue replacement implants. Methods of treatment using such implants are also described. In such methods, polymers that are biocompatible, and biodegradable are also described.
