Hemocompatible Primers Move Beneath Lubricious Top Layers
Dual-layer architectures have moved from specialty neurovascular devices into mainstream peripheral catheters. A hemocompatible primer sits beneath the lubricious surface, addressing thrombus formation that a lubricity layer alone never touched. Roughly 28% of new interventional device programmes launched in 2025 specified a two-layer surface, against 11% four years earlier. The commercial consequence is that coating content per device rises without any change in procedure volume, and it favours suppliers whose two chemistries are validated together. OEMs that mix vendors across the stack carry the interface risk themselves, and most have decided they would rather not.
