Abstract: A puncture sealing system for sealing a vascular puncture comprises an inner member comprising an expandable member at an inner member distal end and an inflation lumen that extends from an inner member proximal end to an interior of the expandable member. The puncture sealing system also comprises an outer member comprising a lumen sized and shaped to allow the inner member to slide therein, an occlusion balloon at an outer member distal end, and an inflation lumen that extends from an outer member proximal end to the interior of the occlusion balloon. The expandable member can be inflated by fluid flowing through the inner member inflation lumen so that the expandable member can inflate in a subcutaneous vessel of a living being, and the occlusion balloon can be inflated by fluid flowing through the outer member inflation lumen so that the occlusion balloon can enable the occlusion of a vascular puncture and contact and apply pressure to a puncture tract extending from the vascular puncture.

Abstract: A system is provided for causing hemostasis at a puncture and a puncture tract. The system includes an inner member comprising an expandable member at its distal end and an inflation lumen that extends from inner member proximal end to an interior of the expandable member. The system further includes an outer member comprising a lumen sized and shaped to allow the inner member to slide therein, an occlusion balloon at its distal end, and an inflation lumen that extends from its proximal end to the interior of the occlusion balloon. The expandable member can be inflated by fluid flowing through the inner member inflation lumen so that the expandable member can close a puncture in a subcutaneous vessel of a living being. The occlusion balloon can be inflated by fluid flowing through the outer member inflation lumen so that the occlusion balloon can contact and apply pressure to a puncture tract extending from the skin of the living being to the puncture.

Abstract: A system for sealing a percutaneous puncture communicating with a blood vessel in a living being and method of use thereof. The system, referred to in the present embodiment, as a balloon closure device, includes an inner member, referred to as an anchor catheter, slidable within an outer member, referred to as an occlusion catheter, and separate expandable members, referred to as balloons, coupled to the distal ends of both the anchor and occlusion catheters. Also, incorporated into the distal end of the anchor catheter are blood vessel locator holes for determining the position of the blood vessel via the percutaneous puncture. The vessel locator includes means for enabling blood from the vessel to flow therethrough so that the position of the vessel can be rapidly determined. Once the balloon closure device has been extended into the puncture and the vessel has been located, the ballon closure device may be deployed.
