Ultra-thin-wall polyimide tubing and coated wire in partnership with Keystone Medical Technologies, Inc.
Polyimide Tubing
- IDs from .007" to .075"
- Wall thicknesses from .0005" to .0035"
- PTFE/polyimide composite material available for lubricious IDs or ODs
- Thermoplastic top coats available in Pebax, nylon, and Tecoflex for increased bondability
Coated Wire
- Polyimide coated copper wire — wire diameters .007" to .075"
- Polyimide or Pebax coated 304SST wire — wire diameters .003" to .075"
Why Polyimide
Polyimide combines very high strength with walls measured in ten-thousandths of an inch, so it delivers column strength, pushability and kink resistance in the smallest possible profile. It holds tight dimensional tolerances, stays smooth and clear, and tolerates high temperatures during downstream processing such as reflow and bonding.
Typical Applications
- Catheter shafts and inner lumens for neurovascular, cardiovascular and electrophysiology devices
- Guidewire and microcatheter components where profile is critical
- Lumen liners and reinforcement layers in braided or coiled catheters
- Insulation for conductors and sensor leads (polyimide coated wire)
- Delivery-system and stent-retention sleeves
Quality & Manufacturing
Keystone Medical Technologies produces filmcast polyimide and PTFE tubing at its Chattanooga, Tennessee facility and extruded tubing in Somerset, Wisconsin, under an ISO 13485:2016 certified quality system, from R&D runs through high-volume production.
