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, 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:
Systems, devices and methods for eluting an agent at a treatment site are disclosed. The devices include an expandable frame and at least one membrane. The membrane may carry an agent to elute at the treatment site. The membrane may allow blood flow at the treatment site during agent delivery.
摘要:
Embodiments of the present invention include methods for the treatment, prevention, or amelioration of vascular disease in diabetic patients. The methods include both implantation of a stent including a first drug. Some embodiments include additional therapy, such as the co-administration of another drug. Some embodiments involve different stent selection for a diabetic patient compared to a non-diabetic patient.
摘要:
A method is described including introducing a delivery device to a point within a renal artery or a renal segmental artery and delivering a treatment agent from the delivery device according to conditions that create a turbulent blood flow and wherein the treatment agent is capable of inhibiting a biological process contributing to nephropathy. In other embodiments, an apparatus and kit are described including a delivery device for insertion to a point within a renal artery or renal segmental artery and delivery of a treatment agent capable of inhibiting a biological process contributing to nephropathy.
