MediCoat DES3000/4000

Sono-Tek stent coating machines are considered the industry standard and are used by most of the largest DES manufacturers in the world. Our ultrasonic coating systems have been used to spray anti-restenosis drug eluting polymer solutions onto implantable stents for decades, with hundreds of systems in operation. We have expertise in spraying hundreds of different medical grade polymer chemistries. Ultrasonic spray nozzles are advantageous in penetrating complex stent geometries, ensuring full coverage of all strut surfaces without webbing. The soft atomized spray adheres well to surfaces and coating morphology characteristics can be adjusted by modifying process parameters. Pressure spray nozzles and air atomizers are not able to apply coatings as uniformly as Sono-Tek ultrasonic coating systems. Coatings applied using ultrasonics are much thinner than can be achieved with dip coating, saving spray material while avoiding webbing. Since ultrasonic nozzles are non-clogging devices, spray quality is not compromised over time due to gradual clogging as seen in pressure nozzle processes.

In addition, our full in-house coating laboratory enables customers to simulate process testing using their stents to help improve and establish process criteria. Our laboratory technicians and engineers have extensive experience coating different types of stents.

Types of Stents Coated Using Ultrasonic Spray (Metal or Bioabsorbable Materials):

·         Arterial
·         Peripheral
·         Sinus
·         Bifurcated
·         Bare Metal
·         Biodegradable
·         Stent Grafts

MediCoat BCC

MediCoat BCC is a standalone coating system for applying ultra-thin layers of anti-restenosis drug polymer+plasticizer coatings onto implantable balloon catheters.

The MediCoat BCC300 is a balloon catheter coating system designed to coat balloons up to 300 mm in length. A rotating cassette fixture holds one catheter up to 2 meters in length. The balloon catheter cassette assembly can be removed for coating other medical devices, making the MediCoat BCC a flexible R&D development system for a variety of medical device coatings.

Balloons are inflated prior to coating using an auto inflation device. A rotational motor rotates the catheter and balloon 360 degrees while a precision clamping device securely holds the catheter tail in place. The balloon can also be indexed to a user specified degree.

Designed for spraying anti-restenosis solutions containing Paclitaxel, Rapamycin (sirolimus), Zotarolimus, Docetaxel, Heparin, or other cell anti-proliferative drug + plasticizer excipient solutions onto catheters mounted with cardiac angioplasty or other drug coated medical balloons. Sono-Tek is the world leader in ultrasonic spraying systems for depositing uniform thin films of anti-restenosis drugs onto implantable devices such as cardiac and peripheral stents. The MediCoat BCC was developed specifically for coating implantable medical balloon catheters.

Ultrasonic Coating Benefits for Balloon Catheters:

·         Highly uniform thin film coatings onto cardiac or other balloon catheters for homogenous drug
          transfer at lesion.
·         Dramatic material savings compared to dip coating.
·         Reliable, repeatable, controllable balloon catheter coatings.
·         Durable coatings with no cracking or peeling ensure proper delivery of the drug at blockage site.
·         Ability to spray targeted areas (stripes) on balloon surfaces if preferred rather than coating the
          entire balloon surface.

Medical grade gasketing on the catheter holder ensures no damage to the catheter assembly or coiled catheter.

Sono-Tek’s new MedXT series of Blood Collection Tube coating nozzles surpasses the performance of older designs, allowing tube equipment manufacturers to integrate the benefits of next generation precision ultrasonic coating into their manufacturing lines.

Ultrasonic nozzle systems uniformly apply clot activators and anticoagulants including Heparin, EDTA, Silica, and Acid Citrate Dextrose. Specially designed for easy integration into high volume OEM manufacturing lines, the unique slim design allows nozzle placement at standard BCT rack distances, with 10-up configurations processing up to 12,000 tubes per hour. Integration of the MedXT Series with the ECHO generator technology offers superior uniformity and repeatability of coatings. The precise fine tuning capabilities of the ECHO produces tighter drop distribution with smaller droplets for consistent and fast drying dispersions.

MedXT nozzles are available with different tip configurations and in different lengths, dependent upon the diameter and length of your tubes.

One example of a common blood collection tube ultrasonic coating application is spraying a silica coating to accelerate clotting. Silica slurries are sprayed onto tube side walls, forming uniform thin films of silica particles. Ultrasonic spray is beneficial in this particular application since the ultrasonic vibration of the nozzle breaks apart any silica agglomerates, ensuring a homogeneous coating onto tube walls.

Sono-Tek ultrasonic nozzles also offer the ability to isolate the atomized spray to the walls of a desired bottom coating area of a BCT or Syringe Barrel, instead of coating the complete tube.

MedXT nozzles are available in 3 different configurations:

MedXT Standalone is a fully integrated machine ready to operate as a complete solution and drop into your manufacturing line.  Available in configurations for 10 or 20 nozzles.

MedXT Retrofit is designed for manufacturers that already have a BCT / Syringe Barrel coating machine and would like to replace existing air spray nozzles with an easy to integrate ultrasonic nozzle package, including liquid delivery and controls.

MedXT OEM is designed for BCT and Syringe Barrel machine builders who would like to use Sono-Tek ultrasonic nozzles on the equipment they are building.

Coatings such as blood clotting agents, antimicrobial, antibacterial, antibiotic, and other pharmaceuticals are commonly applied to topical and implantable dressings and devices.

Other Medical Coating Materials Applied Using Ultrasonic Systems Include:

·         Colloidal silver
·         Thrombin
·         Steroids
·         Titanium Dioxide
·         Acetaminophen
·         Anesthetics
·         Omega-3 fatty acids
·         Antibacterial Peptides and Enzymes (Lysostaphin)
·         NSAIDS (Ibuprofen, Naproxen)
·         Silver silane
·         Silver nitrate

Bandages, surgical masks, wound dressing, hospital textiles, surgical gauze, and other medical patches, are just a few of the surfaces that can be sprayed with uniform solutions and suspensions using ultrasonic spray technology.

A wide range of flow rates can be achieved, and very thin coatings that are highly uniform offer significant savings in spray material and improve the quality of medical coatings while enhancing patient safety through more uniform antimicrobial coatings.

Vortex Nozzle

Sono-Tek Vortex ultrasonic nozzles are proven successful in gas phase, or mist bioreactor systems, such as production of biomass hairy root cultures.

Cell Culture / Bioaerosol Nozzle Applications

Vortex systems are used in bioengineering research applications such as aiding the growth of hairy roots for extraction of antibodies used in cancer treatment and pharma. The ability to fine tune mist properties such as flow rate, droplet size and duty cycle timing results in significantly higher biomass yield than shake flask or airlift cultures (as much as 50% higher yield). Ultrasonic atomization has shown to be a low-cost scalable solution for production of small molecule compounds and proteins from tobacco or other hairy roots. Sono-Tek ultrasonic mist systems have been shown to produce more favorable root density with improved gas exchange than liquid-phase reactors.
