  • Patent number: 9662231
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold has a morphology resulting from a biaxially expanded tube arranged to provide a more balanced, or less anisotropic axial and radial mechanical properties. The scaffold has improved mechanical properties suited for use as a balloon expandable scaffold implanted in a peripheral vessel of the body.

  • Patent number: 9353218
    Abstract: Multifunctional compounds are provided that readily crosslink in situ to provide crosslinked biomaterials. The multifunctional compounds contain a single component having at least three reactive functional groups thereon, with the functional groups selected so as to be non-reactive in an initial environment and inter-reactive in a modified environment. Reaction of a plurality of the multifunctional compounds results in a three-dimensional crosslinked matrix. In one embodiment, a first functional group is nucleophilic, a second functional group is electrophilic, and at least one additional functional group is nucleophilic or electrophilic. Methods for preparing and using the multifunctional compounds, and kits including the multifunctional compounds are also provided. Exemplary uses for the multifunctional compounds include tissue augmentation, biologically active agent delivery, bioadhesion, and prevention of adhesions following surgery or injury.

  • Patent number: 9289318
    Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

  • Publication number: 20140277331
    Abstract: A peripherally implanted polymer scaffold having a high degree of recoil is worked to reduce recoil in the scaffold when initially deployed at a target lesion in the body. The scaffold is plastically deformed from a crimped state to an expanded state by a balloon catheter. The scaffold is contained within a sheath to prevent recoil up until the point of use. Before the scaffold is introduced to the body, the restraining sheath is removed from the scaffold.
