A mesh material may be affixed to the shaft and movable between a collapsed condition and an expanded condition. The balloon may project away from the shaft when the balloon is in the expanded condition. The mesh material may project away from the shaft when the mesh material is in the expanded condition. ## Claims ### Claim 1 A method of guiding a medical apparatus within a patient, comprising: inserting an elongated catheter assembly to a position within an aorta of a patient, the catheter assembly including an elongated shaft having a length direction and a balloon affixed to the shaft, the balloon including a plurality of compartments disposed adjacent to one another in the length direction, the balloon including septums that divide adjacent ones of the compartments from one another in the length direction, each septum projecting away from the elongated shaft transverse to the length direction of the elongated shaft, each septum forming part of two adjacent ones of the compartments, the balloon having first and second lobes each having an oblong cross-section in a plane orthogonal to the length direction, the lobes not being in fluid communication with one another; and inflating the balloon to move it from a collapsed condition to an expanded condition, the balloon projecting away from the shaft. ### Claim 2 (depends on 1) The method of claim 1, further comprising inserting an elongated pigtail catheter into the aorta through a lumen of the elongated shaft. ### Claim 3 (depends on 1) The method of claim 1, wherein inflating the balloon includes flowing a fluid into the balloon through at least one lumen extending from a proximal end of the shaft to the balloon. ### Claim 4 (depends on 1) The method of claim 1, wherein, after the balloon is inflated, a first outer surface of the balloon is disposed adjacent an inner wall of the aorta. ### Claim 5 (depends on 4) The method of claim 4, further comprising inserting a prosthetic valve delivery device into the aorta such that a distal sheath of the delivery device contacts a second outer surface of the balloon. ### Claim 6 (depends on 5) The method of claim 5, wherein the second outer surface of the balloon is located opposite the first outer surface of the balloon. ### Claim 7 (depends on 5) The method of claim 5, wherein the second outer surface of the balloon is defined around an aperture extending through the balloon along a balloon axis that is substantially parallel to a longitudinal axis of the shaft. ### Claim 8 (depends on 1) The method of claim 1, wherein the catheter assembly further includes a mesh material affixed to the shaft, the method further comprising deploying the mesh material to move it from a collapsed condition to an expanded condition, the mesh material projecting away from the shaft. ### Claim 9 (depends on 8) The method of claim 8, wherein, after the mesh material is deployed, the mesh material extends across one or more openings in a wall of the aorta that lead to at least one of the great vessels. ### Claim 10 (depends on 8) The method of claim 8, wherein deploying the mesh material includes sliding an elongated sheath partially surrounding the shaft in a proximal direction relative to the shaft along a longitudinal axis of the shaft. ### Claim 11 (depends on 1) The method of claim 1, wherein the first lobe in the expanded condition projects away from a first side of the shaft in a first direction in the plane transverse to the length direction, and the second lobe in the expanded condition projects away from a second side of the shaft in a second direction in the plane transverse to the length direction, the second side being opposite the first side. ### Claim 12 (depends on 1) The method of claim 1, further comprising inserting the medical apparatus into the aorta such that at least a portion of the medical apparatus contacts the balloon in the expanded condition, thereby guiding movement of the medical apparatus. ### Claim 13 A method of guiding a medical apparatus within a patient, comprising: inserting an elongated catheter assembly to a position within an aorta of a patient, the catheter assembly including an elongated shaft, a balloon affixed to the shaft, and a mesh material affixed to the shaft; inflating the balloon to move it from a collapsed condition to an expanded condition, the balloon projecting away from the shaft; deploying the mesh material to move it from a collapsed condition to an expanded condition, the mesh material projecting away from the shaft; and inserting the medical apparatus into the aorta such that at least a portion of a distal sheath of the medical apparatus passes through an aperture extending through the mesh material along a mesh material axis that is substantially parallel to the longitudinal axis of the shaft.
