Temporary biomaterials

In addition, polyanhydrides have been considered as attractive materials for temporary biomaterials, such as sutures, and bioabsorbable prostheses. Degradation products of these polymers have anti-thrombotic/anti-inflammatory properties. Active polymers namely poly(anhydride esters) stimulate new tissue formation. The resulting combination features make polyanhydrides as ideal implantable materials. 

The exhaustible nature of the oil reserves and the pollution that oil-based technological polymers can have on the environment has rekindled an interest in polymers of natural origin, in particular the biotechnological polymers. Until now, however, the polyhydroxyalkanoates are the only biotechnological polymers that have been developed industrially, occupying a notable position as biodegradable and biocompatible biomaterials for temporary use [1, 2].

Biomaterials are used throughout the cardiovascular system in both temporary and permanent devices. Cardiovascular devices can be divided into three categories temporary external devices, temporary internal devices, and permanent internal devices.

Recent advances in the field of biomaterials and their medical applications indicate the significance and potential of various nanoceUulose in the development of novel classes of medical devices and applications in healthcare and veterinary medicine. The physical and mechanical properties of nanocellulose are attributes that enable nanocellulose membranes to function as effective temporary wound dressings. On the other hand, because implantable biomaterials (i.e., scaffolds) are also needed, a new approach has been undertaken to apply cellulose as a material entirely integrated into the body, either as a bone or skin graft.
