Title:

A Shaping Tool Assembly and Method for Manufacturing of Shape Memory Alloy (SMA) Stent Rings
Value Proposition:

Invention provides a shaping tool and process for manufacturing stent-graft rings
including shaping tool components, process of wire wrapping on to the tool to the
intended profile, tool assembly, and finally, the heat treatment for SMA shape-setting.
Summary Application:
  • Healthcare
  • Niche and Large (Peripheral vascular Stents market in India is expected to reach
    USD 88.8 million by 2030
Advantages:
  • Suitable for Shape-setting of intricate/complex geometry memory stent graft ring
    profiles with better conformability and geometric accuracy
  • A single-step shape-setting and heat treatment process to achieve complex stent
    ring profiles
  • A closed split-type cylindrical shaping tool unlike the open pin-type tool
    conventionally used
  • Self-locking tool design
  • Custom designed spool and guide assembly
