| 20090035346 | Methods and Compositions for Enhancing Vascular Access - Disclosed is an implantable material comprising a biocompatible matrix and cells which, when provided to a vascular access structure, can promote functionality generally. For example, implantable material of the present invention can enhance maturation of an arteriovenous native fistula as well as prolong the fistula in a mature, functional state suitable for dialysis. Additionally, the present invention can promote formation of a functional arteriovenous graft suitable for dialysis as well as promote formation of a functional peripheral bypass graft. Implantable material can be configured as a flexible planar form or a flowable composition with shape-retaining properties suitable for implantation at, adjacent or in the vicinity of an anastomoses or arteriovenous graft. According to the methods disclosed herein, the implantable material is provided to an exterior surface of a blood vessel. Certain embodiments of the flexible planar form define a slot. The materials and methods of the present invention comprise cells, preferably endothelial cells or cells having an endothelial-like phenotype. | 02-05-2009 |
| 20100057039 | DEVICES AND SYSTEMS FOR LOCAL DELIVERY OF INOTROPIC AGENTS TO THE EPICARDIUM - Devices and methods are provided for delivery of a positive inotropic agent to the heart of a patient in need thereof. An epicardial patch includes (i) a backing layer which is impermeable to the positive inotropic agent; and (ii) a drug release layer attached to the backing layer and including the positive inotropic agent and a polymeric membrane material. The polymeric membrane material provides controlled release of the positive inotropic agent to the epicardium to a region of the myocardium and in an amount effective to increase contractility. At least one of the backing layer or the drug release layer includes a tissue coupling portion for affixing the epicardial patch to an area of the epicardial surface. The epicardial patch is dimensioned and compliant to substantially avoid impeding myocardial functionality when affixed to the area of the epicardial surface. | 03-04-2010 |

| 20110002973 | MATERIALS AND METHODS FOR MINIMALLY-INVASIVE ADMINISTRATION OF A CELL-CONTAINING FLOWABLE COMPOSITION - The disclosed invention is based on the discovery that a cell-based therapy can be used to treat, ameliorate, manage and/or reduce the progression of clinical sequelae associated with vascular interventions or cardiovascular diseases, particularly occlusive thrombosis, restenosis, intimal hyperplasia, inflammation and vasodilation. The invention further benefits from the additional discovery that a heretofore undescribed implantable flowable composition is capable of sustaining a confluent population of sufficiently viable cells which can be effectively administered via a minimally-invasive surgical procedure without diminishing the clinical effectiveness or the viability of the cells. The disclosed invention can be used to treat vasculature as well as non-vascular tubular structures such as a fallopian tube. | 01-06-2011 |
| 20110045054 | MATERIALS AND METHODS FOR TREATING AND MANAGING PLAQUE DISEASE - 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. | 02-24-2011 |
