Abstract
Disclosed herein are materials and methods suitable for treating and managing plaque disease, including vulnerable plaque. An implantable material comprising cells, such as but not limited to endothelial cells, and a biocompatible matrix can reduce progression or deterioration of a plaque-associated lesion situated on the interior lumen of said blood vessel. The implantable material is implanted directly on an exterior surface of a blood vessel at or adjacent or in the vicinity of the site of a lesion on an interior lumen. Alternatively, the implantable material is deposited on an exterior surface at or adjacent or in the vicinity of the site of a lesion on an interior lumen by an intraluminal delivery device which traverses or penetrates the vessel wall or by a percutaneous delivery device which enters the perivascular space. Both modes of administration can be preceded by or coincident with an imaging step. The present invention can treat hemorrhage, erosion, fissure, plaque-associated thrombosis and occlusion, rupture, displacement and/or dislodgement of a plaque lesion.

30. A method of treating a plaque-burdened site, the method comprising the step of:
contacting with an implantable material an exterior surface of a blood vessel at or adjacent or in the vicinity of a plaque-burdened site on an interior lumen of said vessel, wherein said implantable material comprises cells attached via cell to matrix interactions to a biocompatible matrix;
wherein said implantable material is in an amount effective to treat the plaque-burdened site; and
wherein the effective amount comprises at least about 2×
105 to 4×
105 cells/cm3 implantable material, wherein said cells are at least about 80% viable, wherein said cells produce at least about 0.5 to 1.0 micrograms heparan sulfate/106 cells/day, wherein said cells produce at least about 200 to 300 picograms TGF-β
1/ml/day, and wherein said cells produce no more than about 200 to 400 picograms b-FGF/ml/day.- View Dependent Claims (31, 32, 33, 34, 36, 37, 43, 44, 45, 46, 47, 48, 49)

35. A method of diminishing clinical sequelae associated with vulnerable plaque in a patient in need thereof, the method comprising the step of:
contacting with an implantable material an exterior surface of said blood vessel at or adjacent or in the vicinity of a plaque-burdened site on the interior lumen of said vessel, wherein said implantable material comprises cells attached via cell to matrix interactions to a biocompatible matrix;
wherein said implantable material is in an amount effective to diminish clinical sequelae associated with vulnerable plaque, said clinical sequelae selected from the group consisting of;
acute coronary syndrome, myocardial infarction, sudden cardiac death; and
wherein the amount effective comprises a total cell load per patient no less than about 2×
103 to no more than about 2×
106 cells per kilogram body weight.- View Dependent Claims (38, 39, 40, 41, 42)
