Abstract
The invention relates to magnesium reinforcements and magnesium-reinforced barrier membranes for use in biomedical applications, such as dental, craniofacial and orthopedic applications. The magnesium reinforcements and barrier membranes are composed of a biodegradable, magnesium/polymer composite. They can be used in a wide variety of applications, such as, but not limited to, vertical and horizontal ridge augmentation, guided bone/tissue regeneration, periodontal bone regeneration, fracture fixation and orthopedic and spinal bone grafting applications; as well as in general surgery (hernia repair) and urogynecological surgery.
Claims15
A method of preparing a biodegradable, magnesium-reinforced polymer composite implant device, comprising:
- selecting bulk magnesium;
- selecting a polymer sheet;
- processing the bulk magnesium to form a pre-determined geometry having a surface, employing a process selected from the group consisting of expanded metal processing and laser cutting;
- and
- applying the polymer sheet onto the surface of the pre-determined geometry.
A biodegradable, magnesium-reinforced polymer composite, comprising:
- a magnesium framework having a surface, in a form selected from the group consisting of mesh, strut and strut-style support;
- and
- a polymer sheet applied to the surface of the magnesium framework.
