 When it's a matter of coating, Time to shelve over spray from mind
  Sahajanand Technologies has created a distinctive Multi-layered Uniform coating machine ' Humming Bird ' essentially deliberate for delivering advanced therapeutics to the surface of medical devices, with the potential to craft clinically enhanced next-generation Drug-Eluting Stents.  
  This machine can produces multilayer coating and use different drug and polymer solutions in each layer.  
  Various drug combinations, for example anti-coagulant and anti-restenosis therapies, can be added in a single drug-eluting stent, facilitate the prospect for chronological therapies and potentially enhanced proven efficiency.  
  ' Humming Bird ' produces Sweet and Pleasant sound while operating furthermore provides serene coating process, which does not expose drugs to callous environment.  
  The stent coating apparatus of the present invention can coat the abluminal surface of a stent at a high speed, and it can deliver a precise amount of coating material to the specific stent surfaces to maintain coating weight and drop size uniformity.  
  As the distance is adjustable from Stent and Nozzle tip relative to the Stents length and size, highest rate of Drug delivery and Bio-molecule halt is achieved, owing to the uniform and speedy flow of drugs from Spray Gun with accurate Spray pattern diameter.  
  The drug is coated on the Stent by simultaneous oscillating motion of the spray gun and rotating motion of the stent around 15 RPM to ensure a speedy, accurate and uniform coating. Stroke of the spray gun can be adjusted as per the stent height.  
  Air tight Sealed Spray chamber covered by Glass with small window to ensure fully dust protective structure, which eventually promote to clean and safe process.  
  With the help of Exhaust fan, the minimal amount of drug spit outside the Stent area during coating was tire out to avoid any hazardous effect.  
  Machine also Provides Flexibility of manipulating and controlling size and accuracy of particulate coatings by adjusting specific operating parameters such as Air pressure, Temperature, Solute concentration, Distance between Stent and Nozzle tip to achieve the desired coating.
