US Patent:

20120077254, Mar 29, 2012

Filed:

Sep 29, 2011

Appl. No.:

13/200731

Inventors:

Margaret C. Morse - Menlo Park CA, US
Qi Liao - Greer SC, US
Craig S. Criddle - Redwood City CA, US
Curtis W. Frank - Cupertino CA, US

International Classification:

C02F 3/34

US Classification:

435262

Abstract:

Semicrystalline bioplastic materials are processed by thermally annealing the bioplastic to increase degree of crystallinity in the bioplastic; and anaerobically biodegrading the thermally annealed bioplastic. The thermal annealing may be performed using a commercial annealing oven. The anaerobic biodegradation may be performed in an anaerobic digester, a landfill, or other suitable environment.

Abstract:

Described here are polymer compositions, methods, and systems for reinforcing a wall of a heart. The polymer compositions may be adapted to form networks, e.g., cross-linked networks, semi-interpenetrating networks, or interpenetrating networks, and placed within the pericardial space or on one or more pericardial tissues. The mechanical properties of the polymer compositions or networks derived therefrom may then be employed to reinforce a heart wall to prevent dilatation of a chamber of the heart and/or expansion of an infarct, e.g., to treat or prevent congestive or chronic heart failure.
