摘要:
Hyaluronic acid (HA) conjugates or crosslinked HAs compositions for coating an implantable device are provided. The implantable device can be used for treating a disorder such as atherosclerosis, thrombosis, restenosis, high cholesterol, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, and combinations thereof.
摘要:
Pro-healing agent formulation compositions, methods and treatments for enhancing vascular healing are disclosed herein. In some embodiments, a pro-healing agent is encapsulated, suspended, disposed within or loaded into a biodegradable carrier for sustained-release delivery to a denuded or damaged endothelium treatment area in a blood vessel. In some applications, the pro-healing agent can accelerate re-endothelialization of a denuded vascular region. In some applications, the pro-healing agent can assist in the regaining of endothelium functionality. The formulation can be delivered by a delivery assembly such as an infusion catheter, a porous balloon catheter, a needle injection catheter, a double balloon catheter or the like.
摘要:
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 can include 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.
摘要:
Polymers containing poly(hydroxyalkanoates) and agents for use with medical articles and methods of fabricating the same are disclosed. The medical article generally comprises an implantable substrate having a coating, and the coating contains a poly(hydroxyalkanoate).
摘要:
Embodiments of coatings for implantable medical devices, such as stents, are disclosed. The devices may include at least one structural element having an abluminal side, luminal side, and sidewalls between the abluminal and luminal sides. The coating may include at least two continuous coating layers. In some embodiments, the luminal side, and all or a majority of the sidewalls are free of at least two of the coating layers.
摘要:
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.
摘要:
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.
摘要:
This disclosure covers polymers, some of which are useful in medical device applications. Some of these medical devices are implantable within a mammalian body, such as in a body lumen. The copolymers comprise at least one alcoholic moiety derived from a diol, triol, or polyol. Additionally, the copolymers comprise an acidic moiety, derived from a polycarboxylic acid, and a biobeneficial moiety. Some of these copolymers are biodegradable or bioerodable. Medical devices comprising these polymers and methods of making these polymers are within the scope of this disclosure.
摘要:
Coatings for implantable devices or endoluminal prosthesis, such as stents, are provided, including a method of forming the coatings. The coatings can be used for the delivery of an active ingredient or a combination of active ingredients.
