Methods, devices, kits and compositions to treat a myocardial infarction. In one embodiment, the method includes the prevention of remodeling of the infarct zone of the ventricle. In other embodiments, the method includes the introduction of structurally reinforcing agents. In other embodiments, agents are introduced into a ventricle to increase compliance of the ventricle. In an alternative embodiment, the prevention of remodeling includes the prevention of thinning of the ventricular infarct zone. In another embodiment, the prevention of remodeling and thinning of the infarct zone involves the cross-linking of collagen and prevention of collagen slipping. In other embodiments, the structurally reinforcing agent may be accompanied by other therapeutic agents. These agents may include but are not limited to pro-fibroblastic and angiogenic agents.

Methods and compositions to treat myocardial conditions

An apparatus and method to treat vulnerable plaque. In one embodiment, the apparatus has a medical device to treat an occlusive plaque, and is also adapted to release a biologically active agent to treat vulnerable plaque located downstream from the occlusive plaque. In an alternative embodiment, the apparatus has an expandable tube attached to the inner surface of a stent, and a layer of endothelial cells seeded on the inner surface of the expandable tube. The expandable tube shields a vulnerable plaque from a body lumen.

Method and apparatus for treating vulnerable plaque

A method including positioning a catheter at a location in a blood vessel; imaging a thickness of a portion of a wall of the blood vessel at the location; identifying a treatment site; advancing a needle a distance into the wall of the blood vessel to the treatment site; and introducing a treatment agent through the needle to the treatment site. A composition including an inflammation-inducing agent and a carrier in the form of microspheres having a particle size suitable for transvascular delivery. A composition including a therapeutic angiogenesis promoter in a carrier and an opsonin-inhibitor coupled to the carrier. An apparatus for delivery of a therapeutic angiogenesis promoter.

Polycationic peptide coatings for implantable medical devices and methods of making the same are described. The methods include applying an emulsion on the device, the emulsion including a polymer and a polycationic peptide. Other methods include incorporation of the polycationic peptide in microspheres and liposomes.

Polycationic peptide coatings and methods of making the same

A method of treating vulnerable plaque comprising intentionally damaging or rupturing the vulnerable plaque using a wingless balloon which is inflated from a wingless unexpanded diameter to a limited expanded diameter. This process produces significant increase in ECM synthesis at the site of the damage or rupture. As a result, the method strengthens the vulnerable plaque while minimizing or avoiding damage to the surrounding wall of the body lumen or damaging a stable plaque mistakenly believed to be a vulnerable plaque. The method of the invention is particularly useful in treating a fibroatheroma type of vulnerable plaque. In one embodiment, the balloon is self-limiting such that it expands compliantly at initial inflation pressures, and above nominal pressure it expands noncompliantly. In an alternative embodiment, the balloon is inflated using a diameter-limiting device, such as a device which limits the inflation pressure or the volume of inflation fluid in the balloon.

Device for treating vulnerable plaque

A medical device comprising a substrate having a plasma polymerized functionality bonded to at least a portion of the substrate. A superoxide dismutase mimic agent having a complimentary functional group to the plasma polymerized functionality is bonded to the portion of the substrate by bonding to the plasma polymerized functionality. The functionalities can be carboxylate, amine, or sulfate groups and/or polyethylene glycol and can optionally include crosslinking groups.
