    Abstract: An electrophysiology map can be generated from a plurality of electrophysiology data points added automatically in response to defined inclusion criteria. Inclusion criteria can generally be grouped into two categories: location-based (e.g., velocity, distance moved, dwell time, and proximity) and rhythm-based (e.g., cycle length and EKG matching). As each electrophysiology data point is collected, it can be tested against one or more defined inclusion criteria, and added to the electrophysiology map when it satisfies all such criteria. Inclusion criteria can also be employed to generate the geometric model underlying the electrophysiology map.

    Abstract: A remotely deflectable electrophysiology/ablation catheter of the type intended for placing into an interior passage of the heart. The distal end of the catheter has a pair of tension/compression members each with a flattened end portion connected to the distal electrode and extending through the catheter casing and attached to an actuator for effecting the tension/compression thereon for remotely curling the distal end of the catheter. Spaced ring electrodes are provided adjacent the distal electrode. A permanent bend is pre-formed in the casing and tension/compression members adjacent the ring electrodes about an axis perpendicular to the elongated tension/compression members. Movement of the remote actuator causes the distal portion of the catheter to curl into a lariat in a plane perpendicular to the axis along the elongated catheter casing, thus permitting electrical mapping or ablation with the distal and/or ring electrodes.

    Abstract: An apparatus for maintaining a robotic catheter system in a responsive state includes a catheter, a plurality of linear translatable control elements, and a controller. In an embodiment, the catheter includes a proximal portion, a distal portion, and at least two steering wires. The steering wires may be configured at one end to control the movement of at least a portion of the distal portion of the catheter and at the other end for connection to a control member. In an embodiment, each control element may be configured to engage or interface with a respective control member, and the controller may be configured to measure a force exerted on at least one control member by a respective control element and further configured to linearly translate the control element to substantially maintain a force within a predetermined range.

    Abstract: A system and method for assessing contact between a medical device and tissue may comprise an electronic control unit (ECU) configured to be coupled to a medical device, the medical device comprising a first electrode and a second electrode. The ECU may be further configured to select the first electrode as an electrical source and the second electrode as an electrical sink, to cause an electrical signal to be driven between the source and sink, to detect respective electric potentials on the first electrode and the second electrode while the electrical signal is driven, and to determine an impedance respective of one of the first electrode and the second electrode according to both of the respective electric potentials.
