Abstract: The methods and devices disclosed herein pertain to the percutaneous treatment of various forms of aortic dissection by at least partially filling the false lumen of the aortic dissection with a stabilization agent percutaneously and steps to decrease the size of the false lumen using the devices. Fluid maybe aspirated from the false lumen to decrease the volume of the false lumen. And the entrance opening between the true lumen and the false lumen may be sealed with a sealing agent such as a biocompatible adhesive. The medical devices disclosed herein generally comprise an extendable sealing element that is used in conjunction with a catheter to expand the true lumen while reducing the size of the false lumen. The device has the ability to aspirate and/or deliver fluid containing the stabilization agent into the false lumen.

Abstract: Methods and devices for the stabilization of heart tissue to treat congestive heart failure using a therapeutic composition are discussed. The therapeutic composition can comprise an elastin stabilization agent, a collagen stabilization agent, or a combination thereof and be applied to the pericardium, to the outer surface of the myocardium, or a combination thereof using a catheter type of device with an attached reservoir. Controlled placement and release of the therapeutic composition can be achieved using a delivery vehicle to formulate the composition.

Abstract: Devices for the isolation of a selected portion of a vessel are described. In some embodiments, the device comprises an introducer sheath and a sealing catheter that are movable relative to each other to create an isolated volume with adjustable size and location. The methods for the treatment of vascular aneurysms using the devices are described. The treatment is achieved through the delivery of an effective amount of stabilization agent to an isolated volume that encompass the aneurysm. The device optionally has an aspiration means to improve the effectiveness of the treatment.
