Tech Note: Electrospinning Q&A

The Electrospinning Company, based in the UK, has developed a proprietary stent coating technology which broadens the design options utilized in the stent coating market and fully automate the process of attaching biomedical textiles onto medical devices. Below are the answers to some of the most commonly as questions about the Electrospinning process:

Q) How does Electrospinning compare to sutured coatings?
A) The benefits of sutureless coatings include:

  • Reduced manufacturing costs
  • Reduced stent profile
  • No pin-holes or tears and a reduced risk of leaks
  • Even stress-strain distribution
  • Uniform coating
  • Smooth interluminal surface

Q) For what applications can Electrospinning be utilised?
A) Electrospinning can be used for a range of medical stent coating including:

  • Cardiovascular:
    • Structural heart and valve replacement
    • Self-expanding stents
    • Coronary stents
    • Balloon expanding stents
    • Occluders
    • Annuloplasty rings
  •  Urology
  • GI tract
  • Neurological shunts
  • Drug delivery
  • Catheters
  • Knitted polymer tubes

Q) What polymers can be electrospun onto stents?
A) We can spin a wide range of medical grade polymers with varying mechanical and biological properties including:

  • Thermoplastic Polycarbonate Polyurethanes
  • Thermoplastic Silicone Polycarbonate Polyurethane
  • Hydrophilic Polyurethane
  • Medical grade PET
  • Degradable synthetic polymers and copolymers including:
    • Poly Lactides (PLA); Poly Lactide Glycolides (PLGA); Poly Caprolactone (PCL); Poly(lactide-co-caprolactone) (PLCL);
  • Biomolecules and additives such as hyaluronic acid, collagen and nanoparticles can also be incorporated
