ELECTROPHYSIOLOGY MAPPING USING CATHETER SPLINES DEFLECTION MODELING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18089428 titled 'ELECTROPHYSIOLOGY MAPPING USING CATHETER SPLINES DEFLECTION MODELING
The system described in the patent application includes an expandable distal-end assembly with electrodes and a processor.
- The expandable distal-end assembly is attached to a shaft for insertion into a patient's organ cavity.
- The processor receives location signals from both the distal and proximal ends of the assembly.
- It also receives signals indicating the change in relative orientation from sensors on the assembly.
- The processor estimates the angular position of splines extending from the proximal to distal end of the assembly.
- Based on this information, it estimates the locations of the electrodes in three-dimensional space.
Potential Applications: This technology could be used in medical procedures such as minimally invasive surgeries or diagnostic imaging.

Original Abstract Submitted
A system includes an expandable distal-end assembly and a processor. The expandable distal-end assembly is coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient, the assembly including one or more electrodes. The processor is configured to (i) receive location signals from each of a distal and proximal location of the distal-end assembly, (ii) receive location signals indicative of a relative orientational angle from one or more sensors that are located at the distal-end assembly and configured to output signals indicative of the change in the relative orientation, (iii) estimate angular position in the azimuthal plane of each of a plurality of splines extending from the proximal to distal end of the distal-end assembly, and (iv) estimate respective locations of one or more of the electrodes in three dimensional space based on the estimated angular position of each of the splines.
