A medical device delivery catheter includes an elongate tubular body including proximal, intermediate, and distal longitudinal segments. The proximal segment extends between a proximal end of the body and a first transition between the proximal segment and the intermediate segment, has a first outer diameter, and includes at least one flexibility increasing cut through a wall of the body. The intermediate segment extends between the first transition and a second transition between the intermediate segment and the distal segment, has a second outer diameter that is less than the first outer diameter, and defines a medical device support region. The distal segment has an initial outer diameter that is greater than the second outer diameter and terminates in a distally tapered region. The body is free of joints and has a uniform tensile strength across the proximal, intermediate, and distal segments and the transitions. |
