Patent ID: 7044934

Claim:
A catheter system comprising: a first elongated shaft, the first elongated shaft defining a lumen, the first elongated shaft having a longitudinal axis, the first elongated shaft having a proximal end and a distal end, a housing surrounding at least a portion of the first elongated shaft, the housing having a proximal end and a distal end, the first elongated shaft slidable within the housing from a first position to a second position, the longitudinal axis of the first elongated shaft defining a curve having a first radius of curvature when the first elongated shaft is in the first position and defining a curve having a second radius of curvature when the first elongated shaft is in the second position, the first radius of curvature being larger than the second radius of curvature and a second elongated shaft, the second elongated shaft defining a lumen, the second elongated shaft slidable within the first elongated shaft from a first position to a second position.
