Abstract:
A bimodal bioabsorbable polymer composition. The composition includes a first amount of a bioabsorbable polymer polymerized so as to have a first molecular weight distribution; a second amount of said bioabsorbable polymer polymerized so as to have a second molecular weight distribution having a weight average molecular weight between about 10,000 to about 50,000 Daltons, the weight average molecular weight ratio of said first molecular weight distribution to said second molecular weight distribution is at least about two to one; wherein a substantially homogeneous blend of said first and second amounts of said bioabsorbable polymer is formed in a ratio of between about 50/50 to about 95/5 weight/weight percent. Also disclosed are a medical device, a method of making a medical device and a method of melt blowing a semi-crystalline polymer blend.
