  • Publication number: 20140186446
    Abstract: Formulations and methods are disclosed which provide controlled, sustained release of a biologic therapeutic to a space within the body. More specifically, formulations comprising a plurality of hydrophilic polymer strands, and methods of forming and administering such formulations, are disclosed. In some embodiments, the formulations exhibit a burst release, an initial release, a triphasic release, and release over thirty to ninety days of the biologic therapeutic. In some embodiments, the formulations exhibit reversible precipitation of the biologic therapeutic into precipitates having a diameter of about 50 nm to about 10 ?m.

  • Publication number: 20140114398
    Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold has a structure that produces a low late lumen loss when implanted within a peripheral vessel and also exhibits a high axial fatigue life. In a preferred embodiment the scaffold forms ring structures interconnected by links, where a ring has 12 crowns and at most two links connecting adjacent rings.

  • Publication number: 20140090231
    Abstract: A method of manufacturing a stent is disclosed. The stent includes a minimum crimped diameter such that in the minimum crimped diameter, a pair of stent rings, between which marker support structures reside, do not make contact with the marker support structures. The crimped profile of the stent of the present invention can be as small as the crimped profile of a same stent but without the marker support structures.

  • Publication number: 20140046254
    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.

  • Publication number: 20140025005
    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.
