USPTO granted patent US12599433B2 to Kardium Inc. on April 14, 2026, covering an intra-cardiac mapping system and ablation method that locates heart chambers and valves using the convective cooling effect of blood flow. The patent discloses both a catheter-deployed expandable net and a scanning catheter configuration capable of performing cardiac mapping and ablation procedures, particularly for treating atrial fibrillation through procedures such as the Maze technique.
This patent grant establishes exclusive intellectual property rights for Kardium Inc. in the United States for cardiac mapping and ablation technology using convective cooling detection. Competitors developing similar cardiac ablation devices should assess whether their technology falls within the scope of these 35 claims. Healthcare providers implementing cardiac mapping or ablation procedures should verify licensing arrangements with Kardium.

Apparatus and method for intra-cardiac mapping and ablation
Grant US12599433B2 Kind: B2 Apr 14, 2026
Assignee
KARDIUM INC.
Inventors
Daniel Gelbart, Samuel Victor Lichtenstein
Abstract
An intra-cardiac mapping system is based on locating the ports through which blood flows in or out the heart chambers. For many procedures, such as ablation to cure atrial fibrillation, locating the pulmonary veins and the mitral valve accurately allows to perform a Maze procedure. The location of the ports and valves is based on using the convective cooling effect of the blood flow. The mapping can be performed by a catheter-deployed expandable net or a scanning catheter. The same net or catheter can also perform the ablation procedure.
