An endovascular support device adapted for local delivery of a therapeutic agent and for minimizing the rate of restinosis having a cylindrical support body with an inside surface and an opposite outside surface, and at least one layer of pericardial tissue covering at least a portion of at least a selected one of the inside surface or the outside surface of the cylindrical support body. At least one therapeutic agent is disposed on a portion of the support device.

Endovascular support device and method of use

A device for the local delivery of a substance into a natural tissue conduit in the mammalian body. The device provides a means for locally delivering a substance into the boundary layer of fluid flowing through the conduit without substantially disrupting the fluid flow therethrough. For example, an indwelling endovascular support device is provided for delivery of a substance locally to a targeted treatment area. Also provided are methods of locally delivering a substance into a natural tissue conduit in the mammalian body utilizing the device of the present invention.

Device and method for non-occlusive localized drug delivery

A device for the local delivery of a substance into a natural tissue conduit in the mammalian body. The device has a substance delivery segment which provides a means for locally delivering a substance into the boundary layer of fluid flowing through the conduit without disrupting the fluid flow therethrough. For example, an indwelling catheter is provided for endovascular delivery of a substance locally to a targeted treatment area. Also provided are methods of locally delivering a substance into a natural tissue conduit in the mammalian body utilizing the device of the present invention.

Device for local drug delivery and methods for using the same

This invention provides a sheath for encompassing at least a portion of a stent to locally deliver a drug to an arterial wall or lumen into which the stent has been inserted, comprising a polymer and a drug incorporated within the polymer, the polymer sheath encompassing at least a portion of the stent and a thickness to allow controlled release of the drug. Also provided is a method of preventing thrombosis and promoting and inhibiting vascular growth in a subject comprising inserting a stent encompassed by the sheath of the invention into a vessel of the subject.

Stent sheath for local drug delivery

Human Neuropeptide Y (NPY) has the formula: H-Tyr-Pro-Ser-Lys-Pro-Asp-Asn-Pro-Gly-Glu-Asp-Ala-Pro- Ala-Glu-Asp-Met-Ala-Arg-Tyr-Tyr-Ser-Ala-Leu-Arg-His-Tyr-Ile-Asn-Leu-Ile- Thr-Arg-Gln-Arg -Tyr-NH.sub.2. Porcine and rat NPY have the same sequence except for Leu instead of Met in the 17-position. Porcine PYY is homologous having 11 different residues. NPY analogs and N-terminally-shortened fragments, e.g. NPY(18-36), which contain one or more specific D-isomer substitutions for the naturally occurring residues (as well as pharmaceutically acceptable salts thereof), dispersed in a pharmaceutically acceptable liquid or solid carrier, can be administered to mammals, including humans, to substantially lower blood pressure over an extended period of time or to counteract hypertension.
