Abstract
Abstract The double mesh balloon catheter device comprises a catheter having a proximal end and a distal end, a double tubular mesh assembly having a proximal end and a distal end, being mounted to the distal end of the catheter and having an outer tubular mesh and an inner tubular mesh. An actuating mechanism is coupled to the proximal end of the catheter and extends through the catheter to the double tubular mesh assembly for moving the distal end thereof to effect axial contraction of the double tubular mesh assembly. Another actuating mechanism is coupled to the proximal end of the catheter and extends through the catheter to the double tubular mesh assembly for causing rotation of the inner tubular mesh relative to the outer tubular mesh.
