樹脂による創外固定器（を開発）

Non-PRO Not for points Japanese to English Medical Medical: Instruments PR advocating medical-commercial tie-ups

This appears in promotional material for a medical device company, so the meaning may be more PR- than strictly medical science-related. There is no real urgency here, because the job involved is long since past; I am just curious because the term had me 'stumped' at the time.
Any ideas gratefully received!
