A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode array with offset spine loops, each spine loop having at least a pair of linear portions and a distal portion connecting the pair of linear portions, and one or more electrodes on each linear portion. The linear portions of the plurality of offset spine loops are arranged in-plane a single common plane, and the distal portions of the plurality of offset spine loops are arranged off-plane from the single common plane.

Catheter having closed loop array with in-plane linear electrode portion

A catheter comprising an elongated catheter body, and an electrode assembly distal of the catheter body, the assembly comprising a plurality of spines, wherein each spine has a distal end that is connected to the distal end of at least one other spine, wherein each spine has an electrode-carrying portion, the electrode-carrying portions of all spines of the assembly being in a single common plane, and wherein all spines of the assembly have a uniform exposed total length.

Catheter having closed electrode assembly with spines of uniform length

A catheter comprising an elongated catheter body, an electrode array distal of the catheter body, the array having a mounting member and at least first and second spine supports. Each spine support includes a base having a planar configuration, and a plurality of spines extending from the base, wherein the first base extends in a first plane and the second base extends in a second plane different from the first plane in the mounting member.

Catheter with stacked spine electrode assembly

An apparatus includes a catheter having a flexible outer sheath and a flexible irrigation tube. The flexible outer sheath defines a first lumen. The flexible irrigation tube is positioned inside the first lumen and includes an inner layer and an outer coating layer. The inner layer is formed of a synthetic polymer compound and has a uniform cross-section with a hollow interior defining a second lumen. The outer coating layer is disposed around the inner layer. The outer coating layer is formed of a polymeric compound and includes first and second isomers. The first isomer is configured to carry a positive electric charge and the second isomer is configured to carry a negative electric charge.

Catheter construction to eliminate static and noise

An apparatus includes a body, a catheter, and a fluid connector assembly. The catheter extends distally from the body and includes at least one electrode and at least one irrigation port. A fluid conduit is in fluid communication with the at least one irrigation port. A fluid connector assembly extends proximally from the body and includes a fluid connector body and a grounding member. The fluid connector body is configured to couple with a complementary connector associated with a fluid source. A proximal end of the fluid conduit is positioned in an interior region of the fluid connector body. The grounding member is interposed between the proximal end of the fluid conduit and the fluid connector body. The grounding member is in communication with the interior region of the fluid connector body such that the grounding member provides an electrical ground to fluid communicated to the fluid conduit via the fluid connector body.

Electrical grounding feature for irrigation fluid path in catheter assembly

A spine that may be used in the electrode assembly of an electrophysiologic catheter having controlled flexibility. The spine may have a flexible core that extends through a length of the spine, a polymeric cover and a plurality of electrodes, each having at least one lead, distributed longitudinally along the spine. An amount of material forming the spine may be adjusted longitudinally along the spine to compensate for changes in flexibility to the spine caused by varying numbers of electrode leads present at different relative longitudinal positions along the spine.

Electrode assembly having spines with controlled flexibility

This disclosure is directed to a catheter having a multi-electrode assembly with a high electrode density. The multi-electrode assembly may be a basket-shaped electrode assembly or a brush-shaped electrode assembly each having a plurality of spines. Each spine includes a flexible wire core of a shape memory material. The flexible wires may have variable cross-section s to control the movement and stiffness of the spines.

Catheter with supporting structure having variable dimensions

This disclosure is directed to a catheter having a basket-shaped electrode assembly with a high electrode density. The basket-shaped electrode assembly may have a plurality of spines, such as up to twelve, each with a plurality of electrodes, such as up to sixteen. The distal ends of the plurality of spines are joined at a distal hub, all of which are fashioned from a single piece of superelastic material.
