1. A device for interconnecting first and second vessels, said device comprising:
- a vessel connection member comprising a fluid communication lumen extending therethrough between first and second openings formed, respectively, at first and second ends of said vessel connection member, wherein said first and second ends are each insertable into said first and second vessels, respectively; and
first and second pairs of support members, each pair consisting of two single loops attached to substantially opposing sides of said first and second openings in said first and second ends of the vessel connection member, respectively, wherein each of the support members is sufficiently flexible so as to angularly adjust with respect to a longitudinal axis of said vessel connection member and to substantially conform to the inner surface of said vessels in which each of the support members are implanted to exert a force against the inner surface of the first vessel which fixes said device in an operative position relative to said vessels.

Abstract
The present invention provides implantable devices and associated methods for interconnecting human vessels in a side-to-side or an end-to-side arrangement rapidly, safely and in a minimally invasive manner. The devices comprise a vessel connector and a intravascular support mechanism for establishing fluid communication between two vessels. Certain embodiments further include a sealing member for further sealing the openings in the vessels created for inserting the subject devices.

14. A device for interconnecting first and second vessels, said device comprising:
-
a vessel connection member comprising first and second fluidically coupled openings formed, respectively, at first and second ends of said vessel connection member, wherein said first end is insertable into said first vessel; and first and second support members each consisting of a single loop attached to said first end of said vessel connection member at substantially opposing sides of said first opening, wherein each of the support members is sufficiently flexible so as to angularly adjust with respect to a longitudinal axis of said vessel connection member and to substantially conform to the inner surface of said first vessel to exert a force against the inner surface of the first vessel which fixes the device in an operative position; and a first sealing member attached to one of an outer perimeter of said vessel connection member adjacent to said first opening so that, when in an operative position, said first sealing member forms a substantially fluid-tight seal around said first opening. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A kit for interconnecting first and second vessels, said kit comprising:
-
at least one device comprising; a vessel connection member having a fluid communication lumen extending between first and second openings formed, respectively, at first and second ends of the vessel connection member, wherein said first and second ends are each insertable into said first and second vessels, respectively; and first and second pairs of support members, each pair of support members consisting of two single loops attached to substantially opposing sides of said first and second openings in said first and second ends of the vessel connection member, respectively, wherein each of the support members are sufficiently flexible so as to angularly adjust with respect to a longitudinal axis of said vessel connection member and to substantially conform to the inner surface of said first and second vessels to exert a force against the vessels to substantially fix the device in an operative position relative to said vessels; and at least one delivery device for delivering said at least one substance to a target site. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
