Sustained Release/Drug Attachment Technology

Sustained drug attachment and release therapies provide a framework to release therapeutic agents over an extended time period from a medical device.

US Patent 6096726 Sustained release of bioactive materials 2000 US Patent 6,683,062 Multicomponent Complex for Use with a Substrate 2004 US Patent Pending Sustained release one-step coating

Patented systems use crosslinking agents to bind the supporting polymers to each other for better strength and resistance to solvents, sterilizing materials, heat and body fluids. Crosslinkers also bind to functional groups on the surface to improve adhesion. For drug delivery applications it is possible to bind and immobilize pharmaceutical agents to the surface allowing for sustained release, or surface immobilization.

* Components in the coating for prolonged release depend on the functionality of additives- see us for more specific chemistries. Macrophages from a Biostable Polymer-coated Stent

One step application of complex

#1 is surface, #2 is optional hydrophilic polymer, #3 are cleavable linkages, #4 is anchor provided by reactive polymer chains in the complex, #5 is embedded and exposed bioactive material


Two step application of complex

#1 is surface, #2 is primer layer of reactive anchor containing linker moiety /or linker moiety alone over reactive surface, #3 is cleavable linkage and #4 is bioactive material.
