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.
Claims13
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.
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.
