Abstract: An ablation catheter includes a tubular shaft having a proximal portion and a distal end and an electrode assembly extending from the distal end of the shaft. The electrode assembly includes a plurality of splines each having a spline proximal portion secured to the shaft, and an opposite spline distal portion. Each spline includes an electrically conductive support member partially disposed within an insulating member. The support member has a proximal end portion disposed within the insulating member and a distal end portion extending distally of the insulating member and terminating at a support member distal end. A plurality of sensing electrodes is disposed along each spline. A spline retainer mechanically engages with at least one of the proximal and distal portions of the splines.

Abstract: Various aspects of the present disclosure may be directed toward apparatuses, systems, and methods that include a medical device including an elongate body having a proximal portion, a distal portion, and three mutually perpendicular planes. The medical device may include a first steering line and a second steering line and a first stiffening material and a second stiffening material. The first stiffening material and the second stiffening material may be configured to maintain planarity of deflection of at least the distal portion of the elongate body.

Abstract: A catheter for ablation of tissue through irreversible electroporation includes an electrode assembly comprising a flexible circuit having a distally located central flex circuit hub and a plurality of flex circuit branches extending proximally from the hub portion, each of the flex circuit branches defining, at least in part, an electrode assembly spline. The flexible circuit further includes a distal ablation electrode including an ablation electrode hub portion, and a plurality of radial segments integrally formed with the ablation electrode hub portion, each of the radial segments extending proximally along a portion of a respective one of the flex circuit branches and terminating in a proximal end, a plurality of proximal ablation electrodes, each of the proximal ablation electrodes located on a respective one of the flex circuit branches and having a distal end spaced from the proximal end of the adjacent radial segment of the distal ablation electrode.
