摘要： Steerable electrophysiology catheters for use in mapping and/or ablation of accessory pathways in myocardial tissue of the heart wall and methods of use thereof are disclosed. The catheter comprises a catheter body and handle, the catheter body having a proximal section and a distal section and manipulators that enable the deflection of a distal segment of the distal tip section with respect to the independently formed curvature of a proximal segment of the distal tip section through a bending or knuckle motion of an intermediate segment between the proximal and distal segments. A wide angular range of deflection within a very small curve or bend radius in the intermediate segment is obtained. At least one distal tip electrode is preferably confined to the distal segment which can have a straight axis extending distally from the intermediate segment. The curvature of the proximal segment and the bending angle of the intermediate segment are independently selectable. The axial alignment of the distal segment with respect to the nominal axis of the proximal shaft section of the catheter body can be varied between substantially axially aligned (0° curvature) in an abrupt knuckle bend through a range of about −90° to about +180° within a bending radius of between about 2.0 mm and 7.0 mm and preferably less than 5.0 mm. The proximal segment curve can be independently formed in a range of about −180° through about +270° with respect to the axis of the proximal shaft section to provide an optimum angular orientation of the distal electrode(s). The distal segment can comprise a highly flexible elongated distal segment body and electrode(s) that conform with the shape and curvature of the heart wall.

摘要： A tool for slitting an elongate sheath from about an elongate member that is disposed within a longitudinally extending lumen of the sheath includes a longitudinally extending tail portion projecting rearward of a slitting edge and a nose portion of the tool; a lower surface of the nose portion is disposed beneath the slitting edge for engaging a portion of the elongate member. The tail portion of the tool, approximately aligned with the sheath lumen when the lower surface, engages the elongate member and a leading edge of the nose portion is within the sheath lumen, is sized to fit within the sheath lumen after the sheath is slit by the slitting edge. A passageway between the nose portion and the tail portion allows a proximal segment of the elongate member to bend away from the tail portion when the elongate member is engaged by the nose portion.
