    摘要: This invention provides a method for synthesizing semi-crystalline polylactides (PLA) even from a lactide mixture including meso-LA and rac-LA. According to the invention, when a mixture of racemic lactide and meso-lactide ispolymerized using a catalyst capable of iso-selectively polymerizing L-lactide and D-lactide, an amorphous poly (meso-lactide) block is formed from meso-lactide and a semi-crystalline poly (racemic lactide) block is formed from racemic lactide by separately polymerizing racemic lactide and meso-lactide by taking advantage of a difference in physicochemical properties between racemic lactide and meso-lactide, whereby polylactide which is semi-crystalline as a whole is produced.

    摘要: An implantable medical lead having a modified electrode surface for imparting current density directionality within an electrode is disclosed. An implantable medical lead includes a lead body having a proximal section and a distal section having a pre-biased shape configured to secure the lead to an inner wall of a blood vessel. An electrode coupled to the distal section of the lead body includes a number of surface features on an inactive portion of the electrode that impart a current density directionality towards an active portion of the electrode that contacts the inner wall of the vessel. Methods for imparting current density directionality within an implantable lead electrode are also disclosed.
