Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

Advanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

IMPLANTABLE PROSTHESES FOR THE INNER EAR

Proceedings of the Canadian Engineering Education Association (CEEA), 2011
The aim of our research is to develop a proof-of-concept implantable vestibular prosthesis. Such a device would be capable of 6 DOF motion sensing based on MEMS technology, to mimic vestibular functions, and provide stimulus to the brain. In this paper, the feasibility of a vestibular prosthesis is reviewed.

Poly(hydroxy‐oxazolidone) Thermoplastic Elastomers for Safer, Greener and Customizable Blood‐Contacting Medical Devices

Advanced Healthcare Materials, EarlyView.
A poly(hydroxy‐oxazolidone) (PHOx) is synthesized from CO2‐based precursors, enabling the up‐cycling of this waste material. After synthesis, PHOx shows thermoplastic properties, and can therefore be processed by many temperature‐dependent techniques. PHOx is hemocompatible, anti‐adhesive, and biocompatible, which is demonstrated in vitro and in vivo ...

Evaluation of Correlation Between Development of Multiple Cracks in Nonendodontically Treated Tooth and Placement of Dental Implants with Prosthesis

Journal of Pharmacy and Bioallied Sciences
Background: The result of increased occlusal stresses might be fractures in the teeth. It is still unclear how possible risk factors may affect the occurrence of tooth cracks after dental implants with prostheses in nonendodontically restored teeth. Aim:
