Title:
METHOD FOR THE PREPARATION OF NEW SEGMENTED POLYURETHANES WITH HIGH TEAR AND TENSILE STRENGTHS AND METHOD FOR MAKING POROUS SCAFFOLDS
Document Type and Number:
WIPO Patent Application WO2004074342
Kind Code:
A8
Abstract:
The invention presents a new method to prepare biomedical polyurethanes with high tensile and tear strengths. Such polyurethanes are especially interesting for making foams thereof, e.g. as meniscus implants. A new method, applicable to the biomedical polyurethanes, has been found to make such foams, that can be used as scaffolds. This method is based on salt leaching and phase separation.
