    摘要: Compositions, methods of fabrication and methods of treatment for the controlled release of a therapeutic substance to a treatment region are disclosed herein. In some embodiments, block copolymer-based release platforms (modified or unmodified) can be used to deliver a therapeutic substance to an inflamed site in, for example, the coronary tree or the kidney glomeri. The platforms can be carriers of at least one therapeutic substance. An external “trigger”, or stimulus, such as radiation, ultrasound, temperature, a magnetic field, a change in pH, a change in ionic strength or release of an enzyme, can be used to destabilize the platform in order to release its payload in a controlled manner once at a treatment site. Delivery devices can include a syringe, an infusion catheter, a porous balloon catheter, a double balloon catheter and the like.
