  • 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: 10231778
    Abstract: Techniques are disclosed for contemporaneously assessing the success of a renal denervation procedure. One or more characteristics of a patient's heart, such as atrioventricular (AV) interval, PR interval and/or heart rate are monitored during an ablation procedure. A change in the heart characteristic detected during the ablation may indicate successful denervation. Accordingly, successive new locations may be targeted for ablation until a change is detected.

  • Publication number: 20180360342
    Abstract: A method and device that provide improved visualization of soft tissue, such as renal arteries, renal veins and lymph nodes in guiding catheter placement and positioning in the renal region or vasculature. The method and device enable visualization of an electrophysiology catheter application in the renal region which provides for improved imaging of renal structures, including renal arteries, along with one or more adjacent anatomical structures, including renal veins, lymph nodes, other adjacent organs and and/or other adjacent soft tissues that may adversely impact the formation of a lesion during a catheter ablation procedure in or around a renal artery.

  • Patent number: 9848948
    Abstract: An ablation catheter adapted for use with a guide wire has a 3-D shaped portion that carries ring electrodes for ablating a vessel or tubular region, including the renal artery. The 3-D shaped portion, for example, a helical portion, enables the ring electrodes to contact an inner surface of the vessel at a plurality of locations at different depths along the vessel to form a conduction block without forming a closed conduction loop which would otherwise increase the risk of stenosis of the vessel. In one embodiment, the catheter has a lumen with entry and exit ports to allow the guide wire to pass through the lumen but bypass the 3-D shaped portion. In another embodiment, the catheter has outer bands providing side tunnels through which the guide wire can pass through.

  • Patent number: 9717555
    Abstract: A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally helical form, and a control handle. The control handle may be adapted to actuate a deflection puller wire for deflecting a portion of the elongated body and a contraction wire for contracting the generally helical form. The generally helical form carries irrigated ablation ring electrodes. A nitinol support member with shape memory extends through the distal assembly and into the elongated body to provide the helical form. The support member may have a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.

  • Patent number: 9668704
    Abstract: The invention relates to a device and to a method for visual assistance during the electrophysiological use of a catheter in the heart, enabling electroanatomic 3D mapping data relating to an area of the heart to be treated to be visualized during the use of the catheter. Before the catheter is used, 3D image data of a body region containing the area to be treated is detected by means of a method for tomographic 3D imaging. The area to be treated or significant parts thereof are extracted from said 3D image data, in order to obtain selected 3D image data. The electroanatomic 3D mapping data and the selected 3D image data obtained are then classed in terms of position and dimension, and are adjacently visualized, for example, during the catheter ablation. The inventive method and associated device enable the orientation of the operator to be improved during the use of a catheter in the heart.

  • Patent number: 9078567
    Abstract: The invention relates to a method and a device for visually supporting an electrophysiology catheter application in the heart, whereby electroanatomical 3D mapping data of an area of the heart to be treated which are provided during performance of the catheter application are visualized. Before the catheter application is carried out, 3D image data of the area to be treated are recorded by means of a tomographical 3D imaging method, a 3D surface profile of objects in the area to be treated is extracted from the 3D image data by segmentation and the electroanatomical 3D mapping data provided and the 3D images representing the 3D surface profile are associated with each other in the correct position and dimension relative each other and e.g. visualized in an superimposed manner during the catheter application. The present method and the corresponding device allow for an improved orientation of the user who carries out an electrophysiology catheter application in the heart.
