摘要:
A method of modifying a medical device such as a stent with nano-constructs is disclosed. The method comprises applying a first fluid to the stent; immersing the stent being wet from the first fluid into a second fluid having a suspension of nano-constructs; and removing the stent from the second fluid and allowing the first and second fluid to be removed such that the nano-constructs are carried by the stent for in vivo application of the constructs to a target location of a mammalian subject. The nano-constructs can be attached to the surface of the stent, can be attached to a surface of the coating of the stent, can be embedded into the stent, or can be embedded into the coating.

An IgG1λ monoclonal antibody to the immunosuppressive drug tacrolimus has improved properties. In particular, this monoclonal antibody, designated 1H6, has reduced cross-reactivity to several tacrolimus metabolites. This antibody is suitable for performance of immunoassays such as homogeneous immunoassays to detect or determine the presence or concentration of tacrolimus in samples such as blood samples. The invention further includes derivatives of tacrolimus derivatized at a non-binding portion of the molecule useful in immunizing antibody-producing animals and in producing such monoclonal antibodies, as well as labeled derivatives of tacrolimus useful as tacrolimus analogues in such assays. The invention further includes immunoassay methods for the detection of tacrolimus and test kits useful in performing such immunoassays.
摘要:
A method including advancing a delivery device through a lumen of a blood vessel to a particular region in the blood vessel; and introducing a composition including a sustained-release carrier and an apolipoprotein A-I (apo A-I) synthetic mimetic peptide into a wall of the blood vessel at the particular region or a perivascular site, wherein the peptide has a property that renders the peptide effective in reverse cholesterol transport. A composition including an apolipoprotein A-I (apo A-I) synthetic peptide, or combination of an apo A-I synthetic mimetic peptide and an Acyl CoA cholesterol: acyltransferase (ACAT) inhibitor in a form suitable for delivery into a blood vessel, the peptide including an amino acid sequence in an order reverse to an order of various apo A-I mimetic peptides, or endogenous apo A-I analogs, or a chimera of helix 1 and helix 9 of endogenous apo A-I.
摘要:
This invention is directed to a method of treating a vascular disease involving administration to a patient by means of an angioplasty balloon a composition comprising a permeability-enhancing substance and a therapeutic agent.
摘要:
Stent scaffolds that include a polymeric structure or structures bonded to the scaffold and extending along their length are disclosed. The polymeric structure extends across some or all of the gaps in struts along the length of the scaffold. Segmented scaffolds are also disclosed that include two or more axial segments arranged end to end not connected by link struts.
