Endovascular Therapy for Post-Thrombotic Syndrome - A Randomized Trial.

The New England journal of medicine·2026

Applying a structured innovation process to interventional radiology (IR) practice yielded 82 observations and 10 new concepts. This demonstrates a feasible method for driving medical technology innovation in IR settings.

Area of Science:

  • Medical Innovation
  • Interventional Radiology
  • Health Technology Assessment

Background:

  • Academic interventional radiology (IR) practices face challenges in systematic medical innovation.
  • Established innovation processes can provide a framework for identifying and developing new medical technologies.

Purpose of the Study:

  • To assess the feasibility and effectiveness of implementing a recognized innovation process within an active academic IR practice.
  • To evaluate the potential of a structured approach to generate clinical needs and innovative solutions in IR.

Main Methods:

  • The Stanford Biodesign Medical Technology Innovation Process was adopted as the framework.
  • Seven IR faculty and four IR fellow physicians participated over four months, documenting observations.

  • Observations were systematically converted into need statements, with a focus on gastrostomy tube-related needs.

    • Main Results:

    • A total of 82 observations were collected, with fellows contributing more (48) than faculty (34).
    • Key observation categories included enteral feeding (11%), biopsy (10%), chest tubes (7%), and chemo/radioembolization (7%).
    • A gastrostomy tube need led to a specification sheet and a brainstorming session generating 10 distinct concepts.

    Conclusions:

    • A formalized innovation process successfully generated a substantial number of clinical observations and potential solutions.
    • The structured approach facilitated the identification of significant clinical needs and the development of 10 innovative concepts.
    • This study suggests that implementing a structured innovation process can effectively guide academic IR practices toward medical innovation.
