Custom Medical Coatings

Each formulation of CovaCoat® can be specifically tailored as a permanent coating to a wide variety of medical devices, and can be engineered to improve lubricity, hemocompatibility, device contamination resistance and controlled delivery of active pharmaceutical ingredients (APIs). 

Formulation: 

A proprietary photochemical process that alters the surface of a variety of medical devices to incorporate or improve several device specific properties including lubricity, hemocompatibility, biocompatibility, antimicrobial resistance, and controlled drug delivery through internal and external coating. 

Approach: 

Our patented process creates a highly durable, low particulate coating technology through surface modification, designed to withstand shear forces and delamination. CovaCoat® coatings can be applied to several medical devices, including silicone devices, peritoneal dialysis catheters, hemodialysis catheters, wound drains, central venous lines, and several other medical devices. 

Compared to other coatings which rely on “grafting to” processes with off-the-shelf polymers, our coatings use a proprietary “grafting from” process to mitigate weak points and potential delamination. Utilizing photo-polymerization to create active grafting sites, new polymer chains are initiated and grown from the surface to form a continuum rather than a discrete coating layer. 

The CovaCoat process can be applied to a wide range of polymeric based devices. Using USP grade the CovaCoat® process has been scaled for commercial production.  

Benefits: 

• Customizable: Providing unique market differentiating solutions for every customer. 
• Highly tunable: Adaptable to varying geometries, devices and materials (pre or post processing), internal and external surface coating. 
• Durable: Covalently linked surface coating withstands very high shearing and abrasion forces. 
• Multifunctional: Allowing for multiple surface properties, functionalities and controlled delivery of single or dual active pharmaceutical ingredients. 
• Controlled delivery: Including but not limited to antimicrobials, antibiotics, peptides and anti‐inflammatories. 
• Cost Effective: A flexible business model allows for creative structures that are mutually beneficial.
