    摘要: A medical device for implantation into vessels or luminal structures within the body is provided, which stimulates positive blood vessel remodeling. The medical device, such as a stent and a synthetic graft, is provided with a coating with a pharmaceutical composition containing a controlled-release matrix and one or more pharmaceutical substances for direct delivery of drugs to surrounding tissues. The coating on the medical device further comprises one or more barrier layers, and a ligand such as a peptide, an antibody or a small molecule for capturing progenitor endothelial cells in the blood contacting surface of the device for restoring an endothelium at the site of injury. In particular, the drug-coated stents are for use, for example, in balloon angioplasty procedures for preventing or inhibiting restenosis.

    摘要: Compositions and methods are provided for producing a medical device such as a stent, a stent graft, a synthetic vascular graft, heart valves, coated with a biocompatible matrix which incorporates antibodies, antibody fragments, or small molecules, which recognize, bind to and/or interact with a progenitor cell surface antigen to immobilize the cells at the surface of the device. The coating on the device can also contain a compound or growth factor for promoting the progenitor endothelial cell to accelerate adherence, growth and differentiation of the bound cells into mature and functional endothelial cells on the surface of the device to prevent intimal hyperplasia. Methods for preparing such medical devices, compositions, and methods for treating a mammal with vascular disease such as restenosis, artherosclerosis or other types of vessel obstructions are disclosed.

    摘要: Therapeutic and drug delivery systems are provided in the form of medical devices with coatings for capturing and immobilizing target cells such as circulating progenitor or genetically-altered mammalian cells in vivo. The genetically-altered cells are transfected with genetic material for expressing a marker gene and at least one therapeutic gene in a constitutively or controlled manner. The marker gene is a cell membrane antigen not found in circulating cells in the blood stream and therapeutic gene encodes a peptide for the treatment of disease, such as, vascular disease and cancer. The coating on the medical device may be a biocompatible matrix comprising at least one type of ligand, such as antibodies, antibody fragments, other peptides and small molecules, which recognize and bind the target cells. The therapeutic and/or drug delivery systems may be provided with a signal source such as activator molecules for stimulating the modified cells to express and secrete the desired marker and therapeutic gene products.

    摘要: A drug eluting medical device is provided for implanting into vessels or luminal structures within the body of a patient. The coated medical device, such as a stent, vascular, or synthetic graft comprises a coating consisting of a controlled-release matrix of a bioabsorbable, biocompatible, bioerodible, biodegradable, nontoxic material, such as a Poly(DL-Lactide-co-Glycolide) polymer, and at least one pharmaceutical substance, or bioactive agent incorporated within the matrix or layered within layers of matrix. In particular, the drug eluting medical device when implanted into a patient, delivers the drugs or bioactive agents within the matrix to adjacent tissues in a controlled and desired rate depending on the drug and site of implantation.
