Claim 13:
14. A guide catheter apparatus insertable through an external body passage of a subject, comprising:
a substantially rigid shaft with a proximal opening, a distal opening, and a lumen extending between the proximal opening and the distal opening;
a guide wire extending through the lumen of the guide catheter; and
a handle coupled to the shaft, the handle having a handle opening, a handle coupling and a structure, wherein the structure is configured to allow a position of the guide catheter apparatus to be controlled by some or all of three fingers of one hand of an operator of the handle, wherein the handle opening is configured to couple a tube to an inflation segment at the distal opening of the lumen, wherein the handle coupling is configured to couple a source of suction to a duct through the handle, wherein the handle has a suction opening between the duct and an exterior of the handle to allow the operator to control an amount of suction, wherein the structure of the handle is adapted to permit the operator to position a thumb or index finger of the hand to move the inflation segment towards or away from the handle, and wherein the structure of the handle is configured to permit the operator to control, by one of the thumb or index finger, an amount of suction by covering the suction opening to redirect suction from the suction opening towards the guide catheter.
