1. Apparatus for removing emboli during an angioplasty or stenting procedure, the apparatus comprising:

  • an elongated tubular member having proximal and distal ends and a lumen extending therebetween, wherein the elongated tubular member comprises discrete proximal and distal sections connected at a junction;

    an inflation port coupled to the proximal end of the tubular member in communication with the lumen;

    a short tubular member;

    an inflatable member having a proximal end coupled to the distal section and a distal end coupled to the short tubular member, the inflatable member in communication with the lumen;

    a coil having a proximal end coupled to the distal end of the elongated tubular member and the short tubular member, the coil having a length that extends through the inflatable member and the short tubular member to form a floppy tip; and

    a sheath slidably disposed on the tubular member, the sheath including a radially enlarged distal end adapted to selectably enclose the inflatable member during retrieval.
