Medical Device Coatings for Neurology

Neurology is the branch of medicine dealing with disorders of the brain and the entire nervous system. Neurologists diagnose and treat of all categories of conditions and disease involving the central and peripheral nervous system.

brainOur Neurology customers diagnose and treat these conditions

  • Acute ischemic stroke
  • Cerebral aneurysms
  • Brain arteriovenous malformations
  • Hydrocephalus
  • Access to the neurovasculature

Neurological medical devices making use of Harland technologies include:

  • Microcatheters which deliver a variety of interventional procedures to the tortuous vasculature of the brain including coils, flow diverters and stents treating intracranial aneurysms.
  • Mechanical thrombectomy catheters treating acute ischemic stroke
  • Neurointerventional guide catheters
  • Neurointerventional guide wires with hydrophilic coating helping neuroradiologists access the neurovasculature.
  • Balloon catheters
  • Cerebrospinal fluid shunts

Neurology devices present special challenges

The remote anatomies combined with fine and tortuous vasculature make a lubricious low-friction surface essential for device delivery systems.   While low surface friction is required, neuro devices must also satisfy strict requirements for particle generation by the coating.  Additionally the nature of neurology devices mean coatings must be precisely applied to very delicate and low strength parts.  Harland specializes in both satisfying these strict coating performance requirements while handling, coating and testing these delicate devices in production.

Infection associated with the implant of a neurological device can have serious consequences.   Systemic treatment with antibiotics is difficult in the brain.   Harland’s drug eluting coatings can provide localized antimicrobial drug delivery in the area immediately around the implanted device, where it can be most effective at reducing infection.

Harland excels at satisfying the special needs of the neurology market

  • Lubricent® Hydrophilic Coatings dramatically reduce device surface friction with vascular tissue.
  • Bacticent® Antimicrobial coatings provide extended release of a variety of infection fighting drugs.

Automated Coaters and Test Systems
Harland offers six families of automated coaters which can apply nearly every coating technology in commercial use today.  Systems are available to coat as few as one part at a time up to large-scale systems designed to coat tens of millions of parts a year.

Working With Us
Access to these technologies is simple, direct and results in a complete coating program.  Partnering with Harland features…

Open collaboration
Harland encourages close customer participation in understanding coating objectives, developing the exact balance of properties to meet these objectives and validating the process to ensure your coating is fully ready for production either at your plant or in Harland’s own Coating Services facilities.

Simple business model
Harland’s coating technologies are accessible through a simple supply agreement and do not require the added cost and time associated with a royalty-bearing license agreement.

Stage-gated process
Harland’s Start Now ™ step-wise process is designed to move your program swiftly and efficiently through to commercial completion all the while giving you complete visibility and control of the process.
