Abstract:
1. A device for a medical intervention of a body lumen, comprising: a directional balloon adapted to be positioned in said body lumen, wherein said directional balloon comprises only a single inflatable section between a proximal end and a distal end of said directional balloon and said directional balloon has varying elasticity between said proximal and distal ends, whereby the varying elasticity results in: (i) the radial inflation of said directional balloon being defined to radially inflate axially in a proximal to distal direction with respect to said directional balloon, and the radial deflation of said directional balloon being defined to radially deflate axially in a distal to proximal direction with respect to said directional balloon, or wherein (ii) the radial inflation of said directional balloon being defined to radially inflate axially in a distal to proximal direction with respect to said directional balloon, and the radial deflation of said directional balloon being defined to radially deflate axially in a proximal to distal direction with respect to said directional balloon.
