1. An assembly, comprising:
- an outer member including a side wall defining an interior bore, a distal region, and an opening in the sidewall, a flexible member located within the interior bore, defining a distal region and including a prebent region that bows relative to the distal region of the flexible member when outside the outer member, a coupler fixedly connected to the distal region of the outer member and the distal region of the flexible member such that the distal region of the flexible member will bow outwardly through the opening and the prebent region will bow relative to the distal region of the flexible member in response to sliding movement of the flexible member toward the distal region of the outer member, and at least one operative element on the flexible member.

Abstract
A catheter assembly comprises a sheath, which includes a side wall enclosing an interior bore, a distal region, and an opening in the sidewall. The assembly also comprises a bendable catheter tube, which is carried for sliding movement in the interior bore. The catheter tube has a distal portion. The assembly further comprises a coupling, which joins the distal region of the sheath and the distal portion of the catheter tube. The coupling causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.

15. An assembly, comprising:
-
an outer member including a proximal portion having an inner surface defining a proximal interior bore, a distal portion having an inner surface defining a distal interior bore, and a portion defining an opening located between the proximal and distal portions, a flexible member carried for sliding movement within the outer member, the flexible member having a distal portion with an outer surface secured to the inner surface of the distal portion of the outer member such that the flexible member will bend outwardly through the opening in response to sliding movement of the flexible member within the interior bore toward the distal region of the outer member, and at least one operative element carried by the flexible member. - View Dependent Claims (16, 17, 18, 19, 20)

21. An assembly, comprising:
-
an outer member including a side wall defining an interior bore, a distal region, and an opening, a flexible member located within the interior bore, defining a distal region and including a prebent region that bows relative to the distal region of the flexible member when outside the outer member, and a coupler associated with the distal region of the outer member and the distal region of the flexible member such that the distal region of the flexible member will bow outwardly through the opening and the prebent region will bow relative to the distal region of the flexible member in response to sliding movement of the flexible member toward the distal region of the outer member. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
