Summary

Researchers developed customizable 3D-printed biliary stents using stereolithography (SLA) resin. While flexible and non-cytotoxic, the stents may deform during catheter placement, requiring further material investigation for improved elasticity.

Area of Science:

  • Biomaterials Engineering
  • Medical Device Development
  • Hepatobiliary Surgery

Background:

  • Bile duct inflammation can obstruct bile flow, necessitating stent placement for drainage.
  • Current plastic stents are inexpensive but have limited patency and can fail at duct junctions.
  • Self-expanding metal (SEM) stents offer better patency but are more costly.

Purpose of the Study:

  • To investigate post-processing and autoclaving variations for stereolithography (SLA) resin to create a suitable biliary stent material.
  • To design and fabricate customizable, 3D-printed polymeric biliary stents.
  • To evaluate the mechanical properties and suitability of the 3D-printed stents for clinical application.

Main Methods:

  • Tested six variations of post-processing and autoclaving on SLA resin.
  • Fabricated customizable, SLA 3D-printed polymeric biliary stents.
  • Performed in silico and experimental 3-point bend tests to assess stent mechanical properties.

Main Results:

  • Optimized post-processing (60 min IPA wash, 10 min UV cure at 40 °C, 30 min autoclave) yielded a flexible, non-cytotoxic polymer.
  • 3D-printed stents successfully allowed bile flow at duct junctures.
  • Simulations predicted peak stress exceeding polymer yield stress during catheter-based deployment (~30° bend).

Conclusions:

  • SLA 3D-printed biliary stents show promise for customizability and function at duct junctures.
  • The current material and post-processing result in a risk of permanent deformation during stent placement.
  • Future research will focus on alternative resins and post-processing for enhanced elasticity suitable for Class II medical devices.
