Degradation behaviour of self-reinforced 80L/20G PLGA devices in vitro.


In vitro degradation of self-reinforced PLGA 80L/20G material and bioabsorbable stents was studied in artificial urine and phosphate buffer solution (PBS) to define if the media have an effect on the degradation rate in urological applications. After six weeks, the Mv of the samples immersed in PBS was 40% (16.7 kDa) from the initial value and 57% (24.0 kDa… (More)
