    摘要: Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product. A polymeric material that includes a SCC polymer may also be fabricated into other medical devices, such as stents.

    摘要: Preferred embodiments of the present invention relate to polymeric medical devices, such as stents. More particularly, the polymeric compositions disclosed herein comprise halogen-containing, tyrosine-derived diphenols, optionally in conjunction with other groups, such as dicarboxylic acids and/or poly(alkylene oxide), such that the medical devices made from these polymeric compositions are bioresorbable and inherently radiopaque, and exhibit physicomechanical properties consistent with the intended uses of such devices.

    摘要: The present invention relates to a method for promoting blood vessel formation in tissues and organs. In particular, the method relates to implantation or attachment of an engineered three-dimensional stromal tissue to promote endothelialization and angiogenesis in the heart and related tissues. The three-dimensional stromal tissue of the present invention may be used in a variety of applications including, but not limited to, promoting repair of and regeneration of damaged cardiac muscle, promoting vascularization and healing during cardiac surgery, promoting blood vessel formation at anastomosis sites, and promoting vascularization and repair of damaged skeletal muscle, smooth muscle or connective tissue.
