Balloon closure device

A puncture sealing system for sealing a vascular puncture, the system comprising:

• an inner catheter system comprising a first catheter comprising a vessel locator system and a second catheter comprising an expandable member, wherein the vessel locator system comprises a lumen extending from one or more vessel locator distal holes in the first catheter to a vessel locator proximal hole in the first catheter;
• an outer member comprising a lumen sized and shaped to receive the inner catheter system 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;
• and
• an obturator slidably receivable within the outer member following removal of the inner catheter system from the outer member, the obturator comprising a distal end positionable in proximity to the vascular puncture,
• wherein the first catheter of the inner catheter system can be positioned within a vessel having a puncture, wherein the position of the first catheter of the inner catheter system within the vessel can be determined by back-bleeding from the vessel through the vessel locator system to provide a perceptible signal indicative of the location of the first catheter of the inner catheter system with respect to the vessel, wherein the second catheter can then be inserted within the outer member so the expandable member can be inflated, wherein the occlusion balloon can then be inflated by fluid flowing through the outer member inflation lumen so that the occlusion balloon can contact and apply pressure to at least a puncture tract extending from the vascular puncture, and wherein the obturator can then be received within the outer member following removal of the inner catheter system from the outer member so that the distal end of the obturator covers at least a portion of the vascular puncture to enable occlusion of the vascular puncture.

A puncture sealing system for sealing a vascular puncture, the system comprising:

• an inner member comprising a vessel locator system comprising a lumen extending from one or more vessel locator distal holes to a vessel locator proximal hole;
• 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;
• and
• an obturator slidably receivable within the outer member following removal of the inner member from the outer member, the obturator comprising a distal end positionable in proximity to the vascular puncture,
