1. A guiding catheter system for accessing a patient'"'"'s heart, comprising:
- an outer jacket, comprising;
an open guide lumen;
at least one inflation lumen provided along an exterior surface of the outer jacket; and
at least one segment of a distal balloon fixably mounted at a distal portion of the outer jacket, the distal balloon in fluid communication with the at least one inflation lumen; and
a stylet disposed within the guide lumen of the outer jacket and comprising a distal pre-formed bend, the stylet rotatable within the outer jacket along a longitudinal axis of the outer jacket, the distal pre-formed bend of the stylet dimensioned to deflect the outer jacket laterally of the longitudinal axis of the outer jacket upon rotation of the stylet.

Abstract
A guiding catheter system employs an outer jacket with one or more inflation lumens provided along the length of the jacket. The lumens are in fluid communication with one or more fluted balloons mounted at a distal end of the outer jacket. A torquable stylet is movably disposed within an open lumen of the outer jacket. A guidewire is movably disposed in an open lumen of the torquable stylet. The outer jacket can be provided with break-away features allowing the jacket to be peeled off of a pacing lead.

12. A method of cannulating a destination blood vessel, comprising:
-
introducing an outer jacket and a stylet of a catheter system into an access vessel;
rotating the stylet within a guide lumen of the outer jacket so that a pre-formed bend on a distal end of the stylet deflects the outer jacket to steer a distal end of the outer jacket;
advancing a guidewire through an open lumen of the stylet to engage the destination blood vessel with a distal end of the guidewire; and
inflating a balloon attached to a distal portion of the outer jacket to engage a portion of the access vessel or the destination blood vessel with the outer jacket. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A guiding catheter system for accessing a patient'"'"'s heart, comprising:
-
an outer jacket having an open guide lumen and a plurality of fluted balloons fixably mounted at a distal portion of the outer jacket, each of the fluted balloons fluidly coupled to an inflation lumen provided along a length of the outer jacket;
a stylet disposed within the guide lumen of the outer jacket, the stylet rotatable within the outer jacket along a longitudinal axis of the outer jacket, the stylet comprising an open lumen; and
a guidewire movably disposed within the open lumen of the stylet. - View Dependent Claims (21, 22, 23, 24, 25)
