Abstract: A catheter with three distinct compression resistance coils, including a body coil and two pull wire coils, is disclosed. The triple coil system can provide maximal resistance to compression of the catheter's proximal shaft, as well as maximization of the curve angle that the catheter tip can achieve. Additionally, the tri-coil catheter can allow for a lower initial compression load and a more flexible proximal shaft. A gap between the outer diameter of the pull wire and the inner diameter of the pull wire compression coil that is equal to about 10-30% of inner diameter of the pull wire compression coil can provide optimal catheter performance.

Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.

Abstract: Electrode assemblies include segmented electrodes disposed on a catheter. The segmented electrodes can be constructed at the tip of the catheter or more proximally located. Tip electrodes can be constructed from an electrically-insulative substrate covered with a conductive material. The conductive material can be deposited on the electrically-insulative substrate to form a single tip electrode or multiple segmented electrodes. In some embodiments the tip electrode can include irrigation flow holes for irrigation. A method of manufacturing a tip electrode comprising a thin layer of conductive material deposited on an electrically-insulative substrate is disclosed. Segmented ring electrodes can be constructed from segmented ring electrodes that can be equally separated around a circumference of a catheter. The segmented ring electrodes can be formed into segmented electrode subassemblies that can then be joined to a catheter shaft.

Abstract: Elongate medical devices with a deflectable shaft section include a lumen liner configured to enhance planarity control of the deflectable shaft section. An elongate medical device includes a deflectable shaft section, a lumen within the deflectable shaft section, and a lumen liner that surrounds and defines the lumen. The lumen liner has an in-plane bending stiffness and an out-of-plane bending stiffness that is greater than the in-plane bending stiffness to provide planarity control of the deflectable shaft section during the cross-sectional bending of the deflectable shaft section.
