1. A medical device for use in a body lumen, said device comprising:

  • a tubular sheath comprising;

    a proximal end;

    a distal end opposite said proximal end;

    at least one reconfigurable section disposed intermediate said proximal and distal ends; and

    an elastic bias section disposed proximal relative to said reconfigurable section, said elastic bias section configured to vary the axial length of said reconfigurable section; and

    an elongate control element defining a proximal end and a distal end, said control element sized to allow longitudinal placement thereof within said sheath, said sheath and control element fixedly attached to one another such that a tensile force is imposed by said sheath on said control element, said tensile force sufficient to bias said medical device in a deformed first shape that can be changed by variation of said tensile force through said elastic bias section such that said medical device assumes a second shape different from said first shape.
