Abstract
The present invention concerns a process for treating bone tissue of animal or human origin, and a corresponding implantable biomaterial. According to the present invention, a fluid in the supercritical state is caused to penetrate throughout the bone tissue. The bone tissue thus treated can then undergo stages of extracting specific proteins. This tissue is intended to be placed on a damaged bone tissue and has mechanical properties at least equivalent to those of natural bone.
Claims21
A process for treating bone tissue to obtain implantable bone grafting tissue with improved mechanical strength, comprising the steps of:
- a) obtaining bone tissue;
- b) removing any organic matter present about said bone tissue;
- and
- c) treating said bone tissue with a fluid in supercritical state adapted to obtain a tissue containing less than 2% fat on average, said fluid penetrating throughout said bone tissue.
A process for treating bone tissue to obtain implantable bone graphing tissue having improved mechanical strength, comprising the steps of:
- a) obtaining bone tissue;
- b) removing any organic matter present about the bone tissue;
- and
- c) treating the bone tissue with a fluid in supercritical state, the fluid penetrating throughout the bone tissue and with a duration of treatment and flow of fluid adapted to obtain a tissue containing less than 2% fat on average.
