Polydioxanone, IV 2.5 dL/g

Polydioxanone (PDO) is a polylactone ester with high degrees of crystallinity and is known for its use in filament sutures, meshes, clips, and other flexible absorbable devices. PDO is available as colorless or dyed homopolymer or copolymerized with PLA and/or PGA. A systematic review of implantable PDO products has shown high-levels of safety in use. The well-known safety profile of PDO has led to further research on PDO-based bio-materials with modified properties for tissue engineering and drug/gene delivery applications.
