Patent Images
1. A particle, comprising:
- a biocompatible block copolymer including at least one first block having a glass transition temperature of at most 37°
C. and at least one second block having a glass transition temperature of greater than 37°
C.,wherein the at least one first block comprises at least one isobutylene monomer and the particle has a diameter that is selected from the group consisting of less than about 100 microns, from about 300 microns to about 500 microns, from about 700 microns to about 900 microns, and from about 1,000 microns to about 1,200 microns.
