Balloon Catheter Coating System for Coating Cardiac Angioplasty
or Other Drug Coated Medical Balloons
The MediCoat BCC ultrasonic balloon catheter coating system is ideal 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 or other implantable drug eluting balloons. Sono-Tek is the world leader in ultrasonic spraying systems for depositing uniform thin films of anti-restenosis drugs onto implantable devices such a cardiac and peripheral stents for a decade. Our expertise in coating precision medical devices with thin, targeted coatings has enabled us to develop the MediCoat BCC designed specifically for coating implantable medical balloon catheters. Go to http://www.sono-tek.com/how-ultrasonic-nozzles-work/ to learn why the unique characteristics of ultrasonic spray produce thinner, more uniform, efficient coatings than other spray deposition methods for precision medical devices. Go to http://digital.mdtmag.com/sept2014/pg16 to read an in-depth article titled “Texturing Prospective with Ultrasonically Coated Balloon Catheters”, written by one of our Application Engineers regarding the efficacy of ultrasonic balloon coating and the specific process considerations for optimal coating characteristics using ultrasonic spray.
Two system configurations are available. The MediCoat BCC185 is designed to coat balloons up to 185 mm in length and the MediCoat BCC300 coats balloons up to 300 mm in length. For both models, the cassette fixture holds one catheter up to 2 meters in length (MediCoat BCC300 shown on the right).
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. The MediCoat BCC is an automated coating system featuring:
- Easy access cassette load door with pneumatic driven automated cassette placement.
- Each cassette fixture holds one balloon catheter up to 2 meters in length.
- Can be configured with either AccuMist or MicroMist precision ultrasonic atomizing nozzles.
- Automated drying sequence following coating using precision gas hypotube.
- Optional dual nozzle configuration for layering of different chemistries and ease of setup for multiple spray applications.
MediCoat BCC Balloon Catheter Coating System Benefits:
- 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
- Capable of atomizing common combinations of chemistries, including hydrophilic carriers and plasticizers for added coating flexibility
- 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
- Windows-based software control and programming
- Medical grade gasket on catheter holder ensures no damage to the catheter assembly or coiled catheter
Balloons are inflated prior to coating. A rotational motor rotates the catheter and balloon 360 degrees while a precision clamping device securely holds the catheter tail in place.
