  • Patent number: 8038991
    Abstract: Embodiments of single component bioscaffolding systems formed of a hydrogel such as hyaluronic acid or salt thereof are described. The hyaluronic acid or salt thereof may be dissolved in a buffer, plasma, or combination thereof to minimize adverse immunogenic responses when applied to a treatment site. Additionally, the hydrogel component includes stem cells to facilitate angiogenesis or facilitate tissue repair and/or regeneration of ischemic tissue, particularly in compromised cardiac tissue. The bioscaffolding may also be formed on a stent or a cardiac medical device.

  • Publication number: 20110190872
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold, after being deployed by the balloon, provides a crush recovery of about 90% after the diameter of the scaffold has been pinched or crushed by 50%. The scaffold also has a reduced crimped profile and a modification of the scaffold's ring structure at the crowns that contributes to the reduced crimped profile.

  • Publication number: 20110144582
    Abstract: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, and a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable.

  • Publication number: 20110144577
    Abstract: A tunable coating formulation is described for a drug delivery balloon comprising a therapeutic agent, an excipient and a plasticizer. The tunable coating includes a first therapeutic agent and a first excipient, and can have a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable. The plasticizer in the formulation has a weigh ratio of excipient to plasticizer below 1:0.1.

  • Publication number: 20110066225
    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: 20100324645
    Abstract: A drug delivery balloon is provided comprising a balloon having a surface, and a coating disposed on at least a portion of the balloon surface, the coating including an cytostatic therapeutic agent, an excipient, and a plasticizer. In accordance with the present subject matter, at least 30% of the coating transfers from the balloon surface within two minutes after inflation of the balloon. Alternatively, at least 30% of the coating transfers from the balloon surface within one minute after inflation. The coating results in an effective pharmacokinetic profile of an cytostatic therapeutic agent in a vasculature or target tissue.
