Bayer MaterialScience has entered into an agreement to acquire PolyBioMed Ltd. based in Sheffield, UK, expanding its product portfolio for medical technology. PolyBioMed, a subsidiary of Lombard Medical Technologies, provides polymer coatings, surface treatments and biomaterials to the medical device industry. The acquisition gives Bayer MaterialScience access to application areas such as coronary drug-eluting stents plus catheter systems for interventional cardiology, urology and neurology. The aim is to provide materials which can enhance design, manufacturing and end-use performance for a variety of medical devices. Bayer MaterialScience is looking to further develop its own polyurethane-based hydrophilic coatings for medical devices with PolyBioMed’s technologies to offer an extended portfolio of surface modification techniques.
