Abstract:
1. A focal ablation assembly, adapted for use with an endoscope comprising an endoscopic tube having proximal and distal ends and defining a channel extending between the proximal and distal ends, the focal ablation assembly comprising: a cryogenic catheter placeable within the channel, the cryogenic catheter defining a catheter lumen and having a distal end placeable at the distal end of the endoscopic tube; a balloon mountable to the distal end of the catheter, the balloon extending distally of both of the distal ends of the endoscopic tube and the cryogenic catheter; the balloon placeable in collapsed and expanded states; a reinforcing element at least partially defining the shape of the balloon in the expanded state, the reinforcing element comprising a stiffening member adapted to extend along the endoscopic tube and having a distal end; the balloon comprising a thermally conductive therapeutic region; the balloon having a generally tubular stem portion, the stiffening member extending into and secured to the stem portion; and a thermally conductive filler material between the stiffening member and the stem portion.
