  • Publication number: 20200229727
    Abstract: A catheter adapted or high density mapping and/or ablation of tissue surface has a distal electrode matrix having a plurality of spines arranged in parallel configuration on which a multitude of electrodes are carried in a grid formation for providing uniformity and predictability in electrode placement on the tissue surface. The matrix can be dragged against the tissue surface upon deflection (and/or release of the deflection) of the catheter. The spines generally maintain their parallel configuration and the multitude of electrodes generally maintain their predetermined relative spacing in the grid formation as the matrix is dragged across the tissue surface in providing very high density mapping signals. The spines may have free distal ends, or distal ends that are joined to form loops for maintaining the spines in parallel configuration.

  • Publication number: 20200155074
    Abstract: A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.

  • Patent number: 10537286
    Abstract: A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.

  • Publication number: 20170100189
    Abstract: A catheter for ablating tissue is disclosed that has a self-centering multiray electrode assembly. The self-centering multiray electrode assembly may have a plurality of spines, each of which a preshaped, expanded configuration that curves to change an orientation of the spine from being directed towards the distal end of catheter body to being directed towards the proximal end of the catheter body. The ablation electrodes engage ostial tissue when a maximal outer diameter of the self-centering multiray electrode assembly is engaged with an inner diameter of a vessel. The compliance of each spine may vary along its length. When the self-centering multiray electrode assembly is engaged within a vessel, the ablation electrodes are brought into contact with tissue and may be used to form lesions in a circumferential path around the vessel.
