摘要： An apparatus includes a shaft and an end effector at a distal end of the shaft. The end effector has a distal end and a proximal end with a longitudinal intermediate point between the distal and proximal ends. The end effector is sized to fit in an anatomical passageway within a cardiovascular system. The end effector includes at least one sensor electrode and a reference electrode. The at least one sensor electrode is configured to contact cardiovascular tissue and thereby pick up potentials. The reference electrode is configured to pick up a potential from fluid in contact with the reference electrode. The reference electrode is located proximal to the longitudinal intermediate point of the end effector. The end effector is configured to prevent the reference electrode from contacting tissue.

摘要： An apparatus includes a catheter, a sensor, a first pair of wire segments, an artifact reduction feature, and a correction module. The sensor is positioned at a distal end of the catheter and is configured to generate a sensor signal. The first pair of wire segments is coupled with the sensor and extends along the length of the catheter. The artifact reduction feature is positioned proximate to the sensor and includes a second pair of wire segments. The correction module is configured to subtract motion-induced artifacts from signals received from the first pair of wire segments, based on motion-induced artifacts from signals received from the second pair of wire segments, to thereby provide a corrected sensor signal.

摘要： A loop assembly for a catheter, the assembly including a primary frame member, a secondary frame member, and a sleeve disposed around least one of the primary and secondary frame members. The primary frame member can have at least a first cross-sectional area and can include a pair of proximal ends extending along a longitudinal axis to a closed distal end. The secondary frame member can have at least a second cross-sectional area different from the first cross-sectional area, can be disposed on at least a portion of the primary frame member between the proximal ends and the closed distal end, and can be configured to slide in at least a first dimension relative to the primary frame member.

摘要： The disclosed technology includes a catheter for electrophysiology applications. The catheter can comprise a shaft extending along a longitudinal axis to a distal end and an end effector coupled to the distal end of the shaft. The end effector can include a plurality of loop members. Each loop member of the plurality of loop members can include a corresponding stress distribution node positioned at a distal portion of the respective loop member and a plurality of electrodes affixed to the plurality of loop members.

摘要： Examples presented herein generally include systems and methods which can contact electrodes to cardiac tissue while sensing electrical potential from fluids near the tissue. The electrodes in contact with the tissue can be carried by an end effector and can be used to sense and/or ablate the tissue they contact. A reference electrode can be insulated by a shaft connected to the end effector so that the reference electrode can sense the electrical potentials from the fluids near the tissue while being prevented, by the shaft geometry, from contacting the cardiac tissue. In some examples, the reference electrode can be tubular, having an inner surface that is configured to contact and sense electrical potentials from the fluids and an electrically insulated outer surface. Configured as such, the reference electrode can serve as an extension of an irrigation tube extending through the shaft.
