First Claim
1. An intracorporeal medical device comprising:
- a first elongate member having a proximal region, a distal region and a distal end;
wherein the proximal region of the first elongate member has a circular cross section defining an outer diameter;
an elongate tubular member comprising a metallic material and defining a lumen there through, the tubular member having a proximal region, a proximal end, a distal region, and a distal end, the proximal region of the tubular member attached to the distal region of the first elongate member at a first attachment region, the tubular member extending in a distal direction away from the first elongate member from the proximal end of the tubular member to the distal end of the tubular member;
wherein the elongate tubular member has a circular cross section defining an outer diameter;
wherein the outer diameter of the elongate tubular member is the same length as the outer diameter of the first elongate member; and
a second elongate member having a proximal region, a proximal end, a distal region, and a distal end, the second elongate member disposed within the lumen of the tubular member, an outer surface of the proximal region of the second elongate member attached to an inner surface of the proximal region of the elongate metallic tubular member at a second attachment region.

Abstract
An intracorporeal device includes a shaft having a proximal section including a first elongate member and a distal section including a tubular member and a second elongate member. A proximal region of the tubular member is attached to the distal region of the first elongate member. The second elongate member is disposed within the lumen of the tubular member, and a proximal region of the second elongate member is attached to the proximal region of the elongate tubular member. As such, in some embodiments, the tubular member can function both as a member joining the first and second elongate members, and as a structural element in the distal section of the shaft providing for desired flexibility, torqueability, and/or pushability characteristics.
