1. An assembly for guiding a medical apparatus within a patient, comprising:
- an elongated shaft having a length direction and a cross-section, the cross-section having a first side and a second side opposite the first side; and
a balloon affixed to the shaft and movable between a collapsed condition and an expanded condition, the balloon including 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, the first lobe in the expanded condition projecting away from the 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 projecting away from the second side of the shaft in a second direction in the plane transverse to the length direction, the balloon including a plurality of compartments disposed adjacent to one another in the length direction of the shaft, the balloon including septums that divide adjacent ones of the compartments from one another in the length direction of the shaft.

Abstract
An assembly for guiding a medical apparatus within a patient includes an elongated shaft and a balloon affixed to the shaft and movable between a collapsed condition and an expanded condition. 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.
