Vascular plug
First Claim
1. A vascular plug for occluding a body vessel, the plug comprising:
- an inflatable element provided with an aperture;
a flow accelerator including first and second ends, the first end providing a greater flow area than a flow area of the second end, the second end being coupled to the aperture of the inflatable element; and
a sleeve disposed outside of and between the first end of the flow accelerator and the inflatable member.

Abstract
A vascular plug for implantation into a patient'"'"'s vessel includes an inflatable balloon and a flow accelerator. The flow accelerator includes a conical portion and a tubular coupling element which couples the conical portion to an aperture to the interior of the inflatable balloon. The flow accelerator will concentrate and therefore accelerate fluid flow into the inflatable balloon. Flow accelerator will increase the pressure of fluid thereby to cause the inflatable balloon to inflate even within a pressurised blood vessel. The plug may include a sleeve which provides a chamber between the flow accelerator and the balloon, into which blood may pass from the inflatable balloon or the flow accelerator to create additional blood statis and as a result thrombosis and a second occlusive barrier.
