This technology is a method and computer-accessible medium for determining catheter contact orientation with optical coherence tomography (OCT) for direct visualization of surfaces during radiofrequency ablation (RFA) therapy.
The quality of lesion formation during catheter ablation procedures depends on the ability to control the contact angle and orientation of the catheter tip. However, these criteria are challenging to determine in vivo, and currently, there are limited methods for providing feedback in real time. Information on the accuracy of tip placement during these catheter-based procedures could increase the success rates of this treatment.
This technology is a grin lens-terminated single-mode fiber that was integrated into a commercial RFA catheter that allows for M-mode optical coherence tomography (OCT) imaging at the catheter tip. This incorporation of OCT allows for direct visualization of the surface during RFA therapy. One contact classifier with two sub-classifiers was developed to classify whether the catheter is in proper contact with the tissue and the angle of the catheter when it is in contact. The technology can be used in a variety of catheter-based applications, which require meticulous tip placement.
This technology has been validated in vivo using fresh swine hearts, achieving 98.51% contact accuracy and 91.21% orientation accuracy.
