Abstract:
An apparatus for use in a blood vessel, comprising:an occlusive device which comprises first and second inflatable occlusive members for partially occluding a blood vessel, said occlusive members spaced apart from each other, and a tubular connector having a diameter less than that of said occlusive members and extending between said occlusive members, wherein inflation of said occlusive members creates a region of hemostasis between an outer surface of said tubular connector and an inner wall of the blood vessel while permitting blood to flow through said tubular connector, and wherein said occlusive members comprise respective balloons of a material having sufficiently low compliance to limit axial lengthening of said balloons such that the axial length (L) of each balloon where the balloon contacts the vessel wall is no more than 50% of the diameter of the balloon when the balloon is inflated to create said region of hemostasis.
