Stretch blowmolding modifies bioresorbable stent properties


Abbott Vascular uses stretch blowmolding to enhance the physical properties of polylactic acid (PLA) used in its ground-breaking Absorb bioresorbable vascular stent.

Used for the treatment of coronary artery disease, the Absorb stent is gradually resorbed into the vessel wall. Last year Abbott released five-year data from a clinical trial, showing efficacy and safety results consistent with an earlier study.

Abbott last year also received CE Mark approval for the stent in Europe and is now further studying the device in an expanded population in Europe. A global trial, including the U.S. and other geographies, is planned for later this year.

The processing and polymer science behind the device was reviewed yesterday at BIOMEDevice at the Boston Convention Center by Mary Beth Kossuth, a senior staff scientist at Abbott Vascular (Abbott Park, IL)....
