ITH Guidewires Stylets

Guidewires and Stylets

We provide a deep set of custom stylet and OEM guidewire solutions for a variety of applications including CVC, PICC and hemodialysis kits.

  • Design and development of finished guidewires and stylets for vascular access, central venous catheter (CVC) insertion, peripherally inserted central catheters (PICCs), and hemodialysis catheter insertion.
  • Transfer of products and processes from one site to another to support product-line transfer, line duplication, low-cost manufacturing, and prototype-to-production migration.
  • Manufacture of custom and standard guidewires and components, including cores, mandrels, stylets, and coils.
  • Design for manufacturability (DFM) to assure that final products can be repeatedly manufactured while meeting quality, reliability, and performance requirements.

Our guidewire and stylets can be provided in a wide range of materials and configurations. Our materials experts work with customers to achieve optimal product performance. The highest-quality materials are matched to the precise design specifications and requirements of every infusion therapy and hemodialysis component and device we manufacture.
