PTFE Coating for Medical Catheter Medical catheter coatings are functional films prepared on the surface of catheter substrates such as PU, PEBAX, PE, PP, silicone, and PEEK. They primarily address clinical problems such as high friction during insertion, vascular endothelial damage, thrombosis, bacterial colonization and infection, and drug release. They are widely used in vascular interventional, urological, neurological, central venous, and balloon catheters. Mainstream Coating Classifications, Materials, and [...]

Medical Guidewire Surface Functional Coating Medical Guidewire Surface Functional Coating | Ultrasonic Spray Coating Solution Medical guidewire coatings are functional thin films prepared on the surface of stainless steel or nickel-titanium alloy guidewire cores for interventional procedures (cardiovascular, neurointerventional, urological, peripheral). Their core functions include reducing friction, protecting blood vessels, preventing thrombosis, and improving delivery/torque performance. They must meet medical device compliance requirements such as biocompatibility, adhesion, abrasion [...]

Microneedle Patch Coating Microneedle Patch Coating | Ultrasonic Spray Coating | Cheersonic Basic concepts Coated microneedle patches are the mainstream category of minimally invasive transdermal drug delivery patches. The core principle is to attach drugs and active ingredients to the needle tip and surface of solid microneedles through specialized processes, without loading drugs onto the patch substrate. When used, the microneedle punctures the stratum corneum of the skin, [...]
