UNIQUE COATING PROCESSES FOR ENHANCING PROPERTIES OF MEDICAL DEVICES AND IMPLANTS

 

INV-15081

 

INVENTORS:  D. Story, D. Mcausland

 

Description

 

The success of medical implants is largely dictated by the interaction between the implant and the surrounding cells. Depending on the implant’s function, it may be necessary to either promote or prevent certain cell attachment. For example, coronary stents require endothelial cell attachment. For dental implants, it is important to prevent the attachment of fibroblast cells, while promoting the attachment of osteoblast cells. The interaction between cells and implants also plays a major role in the chances for infection. This is a critical issue within healthcare. Infections caused from biofilms on medical devices are estimated to cost the US healthcare system an estimated 40 billion dollars annually. This invention relates to several high energy plasma deposition processes that can effectively control the interaction between cells and implanted materials. It achieves this by changing the charge structure of the surface of the material, through adding or stripping electrons and atoms. Through this process, the properties of the implanted device can be customized to achieve optimum success.

 

Value Proposition

 

Key benefits include:

• Provides excellent control over interaction between implant and cells

• Imparts a variety of properties onto material surface, including strong antimicrobial properties

• Promotes and prevents cell attachment where necessary

•Commercial Applications include:

oSpinal Implants / Dental Implants / Ortho Trauma (osteoblast attachment)

oWound Care / Access Ports (antimicrobial surface)

oDialysis / PICC’s / CVC’s / Port Catheters (thrombus reducing surface)

oCoronary Stents (endothelial cell attachment)

oCoronary Stents (polymer-free drug elution surface)

oPacemakers (non-fracturing lead conductor)
