    摘要: A coated balloon device for stabilizing a section of a blood vessel in a living subject is disclosed. The coating layer of the coated balloon comprises a phenolic compound having a plurality of phenolic groups connected to form a hydrophobic core with peripheral phenolic hydroxyl groups. The coating layer of the coated balloon may contain a hydrophilic polymer to facilitate the release of the phenolic compound. The balloon in general is made of a compliant polymer for atraumatic contact with the blood vessel. In some embodiments, the coating of the coated balloon device further comprises a hydrophilic undercoat layer between the balloon and the coating layer. In some embodiments, the coated balloon device further comprises a sacrificial top coating that dissolves upon delivery into the section of the blood vessel and comprises a hydrophilic composition including sugar, sugar derivatives, or a combination thereof.

    摘要: A prosthesis is formed from a biocompatible material having one or more associated cell adhesion stimulating proteins. The biocompatible material can be a ceramic material or a carbon coated material. The cell adhesion stimulating protein can be a structural protein or a polypeptide growth factor, such as vascular endothelial growth factor. Viable cells can be adhered in vivo or in vitro to the biocompatible material with the cell adhesion stimulating protein.

    摘要: A prosthesis is formed from a substrate with an associated attraction compound. The attraction compound binds viable precursor cells to the substrate. Thus, the substrate forms a synthetic tissue supporting viable cells once the substrate is contacted with a solution containing viable precursor cells. Preferred precursor cells differentiate into fibroblasts or into endothelial cells.

    摘要: 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.
