Abstract:
A dissection device may include an inflatable balloon (120) disposed at a distal end (112) of a catheter (110), the catheter having an inflation lumen extending through the catheter to an interior space defined within the inflatable balloon. The inflatable balloon includes a top wall (122), a bottom wall (124) spaced apart from the top wall, an outer perimeter wall (126) extending between the top wall and the bottom wall, and a plurality of inner walls (130) each extending between the top wall and the bottom wall and in sealing contact with the outer perimeter wall at a first end of the inner wall. The inflatable balloon includes a series of interconnected chambers (140) including a central chamber (142) in direct fluid communication with the inflation lumen, and laterally disposed chambers (144) each having an opening (136) fluidly connecting to each adjacent chamber.
