  • Patent number: 9775930
    Abstract: A bioscaffolding can be formed within a post-myocardial infarct region sufficient to cause attenuation of a rate of myocardial infarct expansion. A bioscaffolding may further be formed in the post-myocardial infarct region to cause an increase in posterior left ventricular wall thickness. The gel or bioscaffolding can be formed from a mixture of gel components of different gelation systems. For example, a bioscaffolding can be formed by mixing at least two different components of at least two different two-component gelation systems to form a first mixture and by mixing at least two different components (other than the components that make up the first mixture) of the at least two different two-component gelation systems to form a second mixture.

  • Publication number: 20160374838
    Abstract: Stents including a poly(D,L-lactide)(PDLLA)-based scaffold and PDLLA based therapeutic layer are disclosed. The PDLLA based scaffold may be amorphous and may include a primer layer. Methods of applying the PDLLA-based coating to the scaffold are disclosed with solvent processing methods using a solvent blend are also disclosed. Methods of removing residual solvent from a PDLLA-base coating that also condition the scaffold are disclosed. Methods of treating restenosis that release drugs to prevent restenosis without interfering with the natural positive remodeling of a vessel are disclosed.
