An apparatus includes a catheter and an end effector. At least a portion of the catheter is sized and configured to fit within a lumen of a human cardiovascular system. The end effector is positioned at a distal end of the catheter. The end effector includes an expandable assembly and at least one flex circuit. The expandable assembly is configured to transition between a non-expanded state and an expanded state. The expandable assembly includes at least one deformable strut or cage. Each flex circuit includes a flexible substrate secured, without an adhesive, to the expandable assembly and an electrode secured to the flexible substrate. The expandable assembly in the expanded state is configured to urge the electrode into contact with tissue. The electrode has a fishbone-like configuration that defines a longitudinally elongated portion and a plurality of fingers extending transversely from the longitudinally elongated portion.

Catheter with mechanically expandable element having flex circuit

A spine of an electrode assembly is constructed by simultaneously deploying a plurality of individual bobbins of lead wire radially around the longitudinal axis of a polymeric tube. A free end of lead wire from each bobbin is electrically connected to a respective electrode and the electrodes are sequentially installed from a distal first location on the polymeric tube to a proximal location. Each lead wire may be helically wound around the polymeric tube between the electrode to which the lead wire is electrically connected and a proximally adjacent electrode, such that each lead wire between adjacent pairs of electrodes has an alternating direction of winding.

Systems and methods are disclosed for providing and using an ablation catheter. The catheter may include a ring electrode having a contact force sensor that provides signals to a system controller to indicate whether the ablation electrode is in contact with the tissue to be ablated as well as how much of the ablation electrode is in contact with the tissue.

Ablation catheter with radial force detection

A guide wire luer hub has an elongated hub body with a longitudinal lumen having a plurality of transitions between different lumen sections with different diameters and/or taper angles. The guide wire luer hub is adapted for use with a coaxial guide wire tubing extending from a catheter control handle, where the coaxial tubing has an outer cover or tubing coaxially surrounding a guide wire inner body with a lumen adapted to receive a guide wire, including a guide wire having a floppy, U-bend distal end.
