摘要： The disclosed technology includes an expandable basket assembly of a medical probe that includes (i) a plurality of spines connected to the distal end of the hub and extending along the longitudinal axis and configured to bow radially outward from the longitudinal axis when the expandable basket assembly is transitioned from a collapsed form to an expanded form, (ii) a plurality of electrodes, each electrode of the plurality of electrodes may be attached to a spine of the plurality of spines, (iii) one or more struts respectively attached to at least one of the plurality of electrodes, and (iv) a force sensor attached to the distal end of the hub and at least one of the plurality of struts. The force sensor may be configured to detect a force applied to one or more of the plurality of electrodes via the one or more struts.

摘要： The disclosed technology includes a medical end effector comprising one or more spines extending along a longitudinal axis. The spines further comprising a first surface being outward from the longitudinal axis; one or more contact pads affixed to a portion of the first surface of the spine; and one or more flexible circuits disposed over respective ones of the one or more contact pads, the one or more flexible circuits each comprising an electrode and an inductive coil as one unit.

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.

摘要： An apparatus includes an end effector having loop members with electrodes thereon and is usable with catheter-based systems to measure or provide electrical signals. The end effector can include three loop members that are non-coplanar when expanded unconstrained that become contiguous to a planar surface when the loop members are deflected against the surface, a mechanical linkage that joins the loop members at a distal vertex of the end effector, electrodes having surface treatment to enhance surface roughness of the electrodes, twisted pair electrode wires, a bonded spine cover, and/or any combination thereof.
