Potential application of PDO
PDO polymer is mainly applied for absorbable suture and utilized for the raw material of novel absorbable medical devices. PDO filament is used as monofilament because the filament obtained from PDO is tough and flexible.
Applicable examples of the medical device obtained from PDO polymers are shown with color in follows:
