Abstract:
1. A delivery catheter for use in occluding the flow of blood in a lumen of a vessel of a human vascular system comprising: an elongate tubular member having a distal end, and a wall defining a lumen extending from the distal end to a location proximal of the distal end; and a sealing member having proximal and distal ends, and being positioned about the elongate tubular member such that the sealing member is positionable in direct contact with an outer surface of the elongate tubular member, the sealing member being expandable from a delivery configuration to a deployed configuration, the sealing member being sized to fill the lumen of the vessel in the deployed configuration, the sealing member being positioned about the elongate tubular member such that the elongate tubular member is slidable in relation to the proximal and distal ends of the sealing member while the sealing member is in the deployed configuration and contacting the lumen of the vessel, the distal end of the elongate tubular member being a distal end of the delivery catheter, the sealing member including a plurality of reinforcing elements configured and dimensioned to frictionally engage the elongate tubular member when the sealing member is in the delivery configuration to maintain the position of the sealing member in relation to the elongate tubular member, and disengage the elongate tubular member when the sealing member is in the deployed configuration.
