Patent ID: 8262609

Claim:
A device for performing a surgical procedure, the device comprising: an elongate element having a distal end; and an inflatable structure coupled to the distal end of the elongate element, wherein the inflatable structure comprises: a first lobe, a proximal end of the first lobe being contiguous with the distal end of the elongate element; and a second lobe, a proximal end of the second lobe being contiguous with a distal end of the first lobe; a neck region defined at a junction between the first lobe and the second lobe, wherein a maximum wall thickness of the neck region is greater than a minimum wall thickness of the first lobe, and wherein the maximum wall thickness of the neck region is greater than the minimum wall thickness of the second lobe, wherein when in an inflated, non-distended condition, a maximum radial diameter of the second lobe is greater than a maximum radial diameter of the first lobe, wherein an axial length of the first lobe is greater than an axial length of the second lobe.
