Abstract:
An intravascular occlusion device comprising:an occlusion device body having an exterior surface, a proximal end and a distal end, the occlusion device being closed so that any fluid entering the device from the proximal end is retained therein; a connector provided on the proximal end of the occlusion device body; a first inflatable member provided on the exterior surface of the body adjacent the closed distal end thereof, the member being adapted for inflation between a retracted state and an expended state; a second inflatable member provided on the exterior surface of the occlusion device body, the second inflatable member being adapted for inflation between a retracted state and an expanded state, the second inflatable member being located distally from the first inflatable member; a first inflation lumen formed in the body, the lumen having a proximal end and a distal end, the distal end being fluidly connected to the first inflatable member; a vessel punch member adapted to form an aperture in the side wall of a vessel, the punch comprising: a hollow body member having a cutting flange provided at one end thereof; and a head member separate from the occlusion device body mounted for sliding movement inside the hollow body member between an extended position and a retracted position, the head member adapted for forming an aperture in a side wall of a blood vessel through interaction with the cutting flange; wherein the hollow body member is adapted to simultaneously receive therein at least a portion of the distal end of the occlusion device body and the head member and whereby the device with the inflatable member in the retracted state is adapted to be inserted into the aperture and then the first inflatable member is expanded so that the inflatable member can be drawn against the interior of the vessel and substantially seal the side wall aperture from the fluid flowing through the vessel.
