Expansile device for use in blood vessels and tracts in the body and method

An expansible device for use in a body lumen or tract, the device comprising:

• a tubular member having a proximal end and a distal end;
• an expansible member disposed on the distal end of the tubular member, the expansible member having a contracted configuration and an expanded configuration;
• a deformable membrane at least partially disposed over the expansible member in the expanded configuration;
• and
• a reference stop disposed between the deformable membrane and the distal end of the tubular member.

An expansible device for use in a body lumen or tract, the device comprising:

• a tubular member having a proximal end and a distal end;
• a first expansible member disposed on the distal end of the tubular member, the first expansible member having a contracted configuration and an expanded configuration;
• a first deformable membrane at least partially disposed over the first expansible member in the expanded configuration;
• a second expansible member disposed proximal the first expansible member on a distal end of the tubular member, the second expansible member having a contracted configuration and an expanded configuration.

A method for sealing a puncture site:

• providing an expansible device having a tubular member, a first expansible member disposed on a distal end of the tubular member, a first deformable membrane at least partially disposed over the first expansible member in an expanded configuration, and a second expansible member disposed proximal the first expansible member on the distal end of the tubular member;
• inserting the expansible device in the puncture site;
• deploying the first expansible member to an expanded configuration comprising a spherical shape;
• deploying the second expansible member to an expanded configuration comprising a cylindrical shape.
