Abstract: An irrigated catheter with uniform cooling and/or uniform fluid distribution in longitudinally spaced apart elution holes by varying the diameter of a fluid delivery lumen. A number of elution holes are provided in a tip region of a catheter body, and these elution holes are in fluid communication with the lumen through ducts. The fluid delivery lumen may be provided with a flow constrictor to restrict flow of fluid towards the distal region.

Abstract: A flexible tip electrode for an ablation catheter is disclosed. The catheter includes a catheter body and a hollow elongate tip electrode disposed at a distal end of the catheter body. The electrode includes a sidewall provided with one or more elongate gaps extending therethrough. The one or more elongate gaps providing flexibility in the sidewall for bending movement of the tip electrode relative to a longitudinal axis of the catheter body.

Abstract: A fluid delivery catheter configured to allow optimal fluid distribution through each electrode by varying the diameter of a catheter lumen is disclosed. Uniform or different fluid flow rates through longitudinally spaced apart elution holes may be achieved. Exemplary fluids for use with the catheter include a cooling fluid, a therapeutic fluid, and a medication.

Abstract: A fluid delivery balloon ablation catheter configured to allow uniform fluid distribution through each electrode by varying the diameter of the main lumen. The catheter comprises an elongated tubular catheter body having a distal end, a proximal end, and a lumen extending longitudinally within the catheter body. A number of elution holes are provided in the catheter tip region, and these holes are in fluid communication with the lumen through ducts. As such, cooling fluid is delivered from the pump, through the lumen through the ducts, and out of the holes to the environment outside of the catheter. The main lumen has at least one tapered flow constrictors to restrict flow of fluid towards the distal region of the lumen. The catheter has multiple half-dome balloons, with the distal balloon being the smallest, and the proximal balloon being the largest balloon. The multiple-balloon catheter helps when using the ablation catheter in a funnel-shaped vessel.
