摘要:
The present invention relates to medical devices, and in particular, medical devices that have an inorganic coating, e.g., a coating capable of releasing inorganic nanoparticles into a passageway to be treated with the medical device.
摘要:
Compositions and methods for tissue repair are provided including cell binding peptides and growth factor binding peptides. The cell binding peptides bind to one or more of stem cells, fibroblasts, or endothelial cells. The growth factor binding peptides include platelet derived growth factor (PDGF) binding peptides and growth differentiation factor (GDF) binding peptides. The tissue for repair includes tendon, muscle, connective tissue, ligament, cardiac tissue, vascular tissue, or dermis. Implantable devices for tissue repair are provided to which the cell and growth factor binding peptides are attached, such as acellular extracellular matrix having attached binding peptide.
摘要:
The present disclosure in a broad aspect provides for diazeniumdiolated phosphorylcholine polymers and associated methods for achieving nitric oxide release. The present polymers have superior biocompatibility and are useful for coating or fabricating medical devices such as a vascular stent.
摘要:
Provided is a vector for use in delivering a therapy to or removing a therapy from a site within a patient, wherein the vector comprises: a) a binding moiety; and b) a therapeutic agent, wherein the binding moiety comprises a metal-binding protein, polypeptide or peptide which is bound to or encapsulates a magnetic or magnetisable substance, and wherein the vector is to be administered using a device comprising an electromagnet and an element suitable for bringing the therapeutic agent into proximity with the site.
摘要:
