Low-profile electrospun coatings and coverings for minimally invasive medical devices
The Caladrix® platform provides electrospun coatings and coverings on medical devices, textiles, meshes, stents, valves, frames and implants.
It helps device teams add functional surface performance – including permeability control, adhesion, flexibility and tissue interaction – while supporting the low-profile requirements of minimally invasive devices and delivery systems.
For cardiovascular, vascular and other implantable applications, Caladrix® coatings and coverings are designed with development, validation, scale-up and manufacturing in mind.

Direct electrospun fibre deposition for coatings, coverings and hybrid structures
The Caladrix® platform uses electrospinning to deposit ultra-fine fibres directly onto or around medical device structures, including textiles, meshes, frames, stents, valves and implants. Electrospun materials can be applied as selective coatings, full coverings or multi-layer structures to support adhesion, encapsulation, permeability control, flexibility, surface behaviour and low-profile device coverage.
Beyond the coating itself, the platform enables device-specific engineering, tailoring materials around the device, its delivery system and the performance requirements it must meet throughout development, validation and scale-up.

Designed for devices where profile, delivery and coating performance matter
Minimally invasive devices often need coatings and coverings that add function without compromising profile, flexibility or deployment.
This reflects a wider shift in cardiovascular and minimally invasive device design: teams increasingly need coatings that add functionality without adding thickness to devices delivered through catheters.
In cardiovascular and vascular applications, coatings can influence how a device seals, handles, moves through a delivery system, interacts with tissue and performs after deployment.
The Caladrix® platform supports this by enabling thin, flexible electrospun coatings and coverings that can be engineered around permeability, adhesion, delamination risk, mechanical behaviour and device geometry.
This is especially relevant for heart valve textiles, covered stents, occlusion devices, vascular access devices, nitinol frames and catheter-delivered implants — where small changes in thickness, friction, permeability or coating integrity can affect development and performance.
Caladrix Technology Benefits
Electrospun Coating Performance Engineered to the Device – Designing coatings and coverings around device performance requirements rather than as separate surface layers
Low-Profile Coatings and Coverage – Delivering enhanced functionality at approximately 20-50 microns where application requirements allow
Permeability Control – Tuning coating structures to influence permeability, sealing behaviour and fluid movement across surfaces
Adhesion and Reduced Delamination Risk – Supporting robust integration between electrospun layers and underlying textile, frame or implant structures
Flexible Mechanical Performance – Engineering coatings and hybrid structures that flex, conform and move with the device during use
Sutureless or Reduced-Suture Construction – Enabling electrospun fibres to integrate with device structures while reducing reliance on sutures
Selective Coating or Full Encapsulation – Applying electrospun material only where needed or creating full coverings and multi-layer structures
Hybrid Textile Structures – Combining electrospun fibres with woven, knitted or mesh materials for structural and functional performance
