Abstract

A device and method are disclosed for partially occluding a blood vessel such that an area of hemostasis within the blood vessel is created without interrupting the blood flow through the blood vessel. The device comprises a first and second occlusive members for partially occluding a blood vessel, spaced apart from one another, wherein the occlusive members are inflatable to at least the inner diameter of the blood vessel. A tubular connector interconnects the first and second occlusive members and forms a conduit which allows the blood to flow through. When the occlusive members are inflated, an area of hemostasis is created between an outer surface of the tubular connector and an inner wall of the blood vessel while blood continues to flow through the tubular portion. A tube adapted to extend through an opening in the blood vessel to deploy the device includes multiple lumens, such as an inflation lumen to inflate the device and a suture lumen to collapse the device.

Claims

1. A method of manufacturing an inflatable device, comprising:

forming a structure from a single piece of low compliance material, said structure having a pair of balloon portions and a pair of tubular portions, such that one of the tubular portions extends between the balloon portions; and

inserting of said tubular portions inside tubular portion to form a double walled tube between the balloon portions.

2. The method of claim 1, comprising inserting an inflation tube between the walls of the double-walled tube.

3. The method of claim 1, comprising providing stiffening members in said low compliance material.

4. An inflatable device, comprising:

a structure formed from a single piece of low compliance material having a pair of balloon portions and a pair of tubular portions, said tubular portions extending between said balloon portions, one of said tubular portions within the other of the tubular portions to form a double-walled tube between the balloon portions.

5. The device of claim 4, comprising an inflation tube positioned to introduce inflation fluid between the double wall.

6. The device of claim 4, wherein the double-walled tube is open at ends thereof, said balloon portions surrounding said ends, respectively.
