1. A delivery system for stabilizing a catheter shaft near a treatment location within a patient'"'"'s body, the system comprising:
- a catheter shaft having a distal end portion, the distal end portion having increased stiffness relative to rest of the catheter shaft; and
at least one pull wire extending from the distal end portion of the catheter shaft to a proximal portion, the pull wire being configured to cause the distal end portion to flex to wedge the distal end portion of the catheter shaft within the aortic arch.

10. A delivery system for stabilizing a catheter shaft near a treatment location within a patient'"'"'s body, the system comprising:
-
a catheter shaft having one or more lumens that extend along the length the catheter shaft, the one or more lumens; one or more stability members sized to be received within respective ones of the one or more lumens of the catheter shaft to increase the stiffness of the catheter shaft at a distal end portion of the catheter shaft; and at least one pull wire extending from the distal end portion of the catheter shaft to a proximal portion, the pull wire being configured to cause the distal end portion to flex to wedge the catheter shaft within the aortic arch.

13. A method of stabilizing a catheter shaft near a treatment location within a patient'"'"'s body, the method comprising:
-
delivering a distal end portion of a catheter shaft through the descending aorta and across the aortic arch of the patient, the distal end portion having increased stiffness relative to rest of the elongate shaft; and pulling at least one pull wire that extends from the distal end portion of the elongate shaft to a proximal portion to flex the distal end portion so that a first portion of the catheter shaft contacts the inner wall of the aortic arch and a second portion of the catheter shaft contacts the outer wall of the aortic arch to wedge the catheter shaft within the aortic arch. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method of stabilizing a catheter shaft near a treatment location within a patient'"'"'s body, the method comprising:
-
delivering a distal end portion of a catheter shaft through the descending aorta and across the aortic arch of the patient, the catheter shaft having at least one lumen extending from the distal end portion to a portion of the catheter shaft external to the patient'"'"'s body; inserting at least one stability member through the at least one lumen to cause the distal end portion of the catheter shaft to stiffen and move into contact with a portion of an outer wall of the aortic arch to stabilize the catheter shaft within the aortic arch. - View Dependent Claims (20, 21)
