  • 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: 10632286
    Abstract: A catheter includes a tip electrode with a shell and a support member to provide a plenum chamber. The plug is formed with a U-shaped passage for a safety line to wrap around and secure the support member (with the shell affixed thereto) to the catheter. Additional passages are formed in the plug to accommodate components such as irrigation tubing, lead wire and thermocouple wire pair. A method of manufacture provides distal installation and/or anchoring of the safety line, lead wire and thermocouple wire pair in the support member prior to sealing the support member and mounting the shell.

  • Publication number: 20200038105
    Abstract: A method for the treatment of a patient for the purpose of lowering blood pressure and/or treating other medical conditions such as cardiac arrhythmias. A catheter having an ablation element is placed inside the body of a patient and is directed to a targeted location either on in the abdominal aorta where the right or left renal arteries branch from the aorta at or near the superior junction or ostia or on the inside of the inferior vena cava near the junction with the right renal vein or in the left renal vein at a position spatially near where the left renal artery branches from the abdominal aorta. Catheters designed for use in the method where these targeted locations are also disclosed and claimed.

  • Publication number: 20190167347
    Abstract: An irrigated ablation catheter adapted for direct tissue contact has micro-elements that provide more accurate sensing of tissue, including thermal and electrical properties for temperature and impedance measurements. The micro-elements extend through a hollow chamber of an irrigated ablation electrode, and distal ends thereof can protrude outside of electrode or be flush with the electrode. The micro-elements have a protective guide tube in which components enabling temperature sensing or electrical sensing are encased.

  • 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: 9592091
    Abstract: A catheter adapted for simultaneous tissue contact with two opposing ring electrodes carried on a generally linear portion of an electrode assembly is adapted to straddle an ostium for ablating two lesions along a chord of the ostium, wherein the generally linear portion is stabilized on the ostium to ensure proper tissue contact when a force is applied down the length of the catheter body.

  • Publication number: 20160367317
    Abstract: A catheter has a catheter body and a distal tip section with needles that are positioned radially to extend outside of the distal tip section to pierce and penetrate tissue layers of a vessel or tubular region. The needles are supported in a retracted position inside the distal tip section on an elongated support member. For deployment, the needles are lifted and a portion thereof pushed through openings in the distal tip section by an actuator that is longitudinally slidable on the elongated support member. The actuator has a tapered end to help lift the needle onto the actuator. In another embodiment, an inflatable balloon member with needles is movable between retracted and deployed positions.

  • Patent number: 8900228
    Abstract: An irrigated ablation catheter adapted for direct tissue contact has micro-elements that provide more accurate sensing of tissue, including thermal and electrical properties for temperature and impedance and intracardiac ECG measurements. A pressure sensing assembly adds the ability to measure the force at the tip of the catheter as well as to have the micro-elements for accurately sensing tissue parameters. A system uses signals from the micro-elements (impedance, temperature, and ECG signals) as well as the measure of force or pressure at the tip electrode order to provide the operator with a means to control lesion depth, size, transmurality and to ablate tissue until successful treatment of an arrhythmia is achieved.
