Modification of tubular chitosan-based peripheral nerve implants: applications for simple or more complex approaches

Use of Chitosan Conduit for Bridging Small-Gap Peripheral Nerve Defect in Sciatic Nerve Transection Model of Rat

Objective-To evaluate effect of chitosan conduit for peripheral nerve regeneration using sciatic nerve transection model in rat Design- Experimental in vivo study. Animals- Sixty healthy male Wistar rats. Procedures-The rats were divided into four experimental groups (n=15) randomly. In sham group the left sciatic nerve was exposed through a gluteal muscle incision and after careful...

Nerve regeneration through artificial tubular implants.

Nanotechnology for peripheral nerve regeneration

Peripheral nerve injuries (PNI) can lead to lifetime loss of function and disfigurement. Different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. Designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. Utilization of absorbable and non-absorb...

Competitiveness of chitosan-based implants

Biomaterials have been extensively developed and applied in medical devices. Among these materials, bioabsorbable polymers have attracted special attention for orthopedic applications where a transient existence of an implant can provide better results, when compared with permanent implants. Chitosan, a natural biopolymer, has generated enormous interest due to its various advantages such as bi...
