摘要： The disclosed technology includes a medical probe including a tubular shaft having a proximal end and a distal end. The tubular shaft can extend along a longitudinal axis. The medical probe can include an expandable basket assembly proximate the distal end of the tubular shaft. The expandable basket assembly can include a single spine comprising a resilient material extending generally linearly along the longitudinal axis in a collapsed form and forming a spiral member defining a generally spherical outer periphery in an expanded form. One or more electrodes can be coupled to the single spine. Each electrode can include a lumen offset with respect to a centroid of the electrode so that the single spine extends through the lumen of each of the one or more electrodes.

摘要： The disclosed technology includes an expandable basket assembly for a medical probe, which may include a single unitary structure comprising a plurality of spines converging at a central spine intersection, the central spine intersection being positioned on a longitudinal axis of the expandable basket assembly at a distal end thereof. The plurality of spines may include a first layer and a second layer attached to the first layer and including a central cutout about the central spine intersection that exposes the first layer at the central spine intersection. The plurality of spine may include a central electrode attached to the first layer at the central spine intersection via a central aperture in the first layer at the central spine intersection. The second layer may be configured to articulate independently of the first layer at the central spine intersection.

摘要： The disclosed technology includes a medical probe comprising a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis. The medical probe further comprises an expandable basket assembly coupled to the distal end of the tubular shaft. The basket assembly includes a plurality of electrodes with each electrode of the plurality of electrodes having a lumen therethrough. The basket assembly further includes a plurality of spines 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. Each spine includes a proximal and a distal end and a strut passing through the lumen of an electrode. The strut includes a mechanical retainer disposed on the strut to prevent the electrode from sliding proximally or distally along a length of the spine.

摘要： The disclosed technology includes an electrode for a medical probe having an elongated body. At least a portion of the elongated body can be electrically conductive. The elongated body can define a lumen that extends through the elongated body along a longitudinal axis of the elongated body. The electrode can include a locking stub that extends at least partially into the lumen so that the locking stub is locked to a member inserted into the lumen.

摘要： Wiring is disclosed herein that is configured to supply IRE ablation signals through a catheter body and is resistant against dielectric breakdown, arcing, and noise during ablation. The wiring includes a highly conductive core, a conductive cover surrounding the core that has lower electrical and/or thermal conductivity than the core, and an insulative jacket surrounding the conductive cover. A catheter including such wiring may be suitable for supplying electrical signals to tissue to perform IRE ablation. In some examples, such a catheter can also be suitable for reversible electroporation and/or RF ablation.

摘要： A medical device control handle or catheter includes deflection assembly and at least one of the following: a disk actuator, a lever actuator and a ring actuator for actuating additional puller wires in manipulation of multiple features of the medical device or catheter independently of each other. The disk actuator has a common rotational axis with but is rotationally independent of the deflection assembly. The lever actuator has a separate rotational axis. The ring is mounted outside of the control handle and rotatable relative to the control handle to actuate another puller wire for manipulating another feature of the catheter. Each of the disk, lever and ring actuators are of a design that allows existing control handles and catheters to be readily modified to include these actuators.

摘要： Disclosed is a system and method to provide information about an ablation lesion zone (width or depth). Such information on the ablation lesion zone can be projected onto an electro-anatomical map based on the magnitude of the contact force, number of times energy were delivered to tissues and pre-clinical data.
