ABLATION OF LESIONS OF LOW-MEDIUM DEPTHS USING ULTRAHIGH RADIOFREQUENCY (RF) POWER FOR ULTRASHORT DURATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024018 titled 'ABLATION OF LESIONS OF LOW-MEDIUM DEPTHS USING ULTRAHIGH RADIOFREQUENCY (RF) POWER FOR ULTRASHORT DURATIONS

Simplified Explanation

The abstract describes a method of body tissue ablation using an ultrahigh-power ultrashort-duration (UPUD) ablation protocol. The protocol specifies an ablation signal with a target ablation power of at least 400 watts and a pulse duration of no more than three seconds. This method is used to create a specific lesion in the tissue of a patient's body by applying the ablation signal through an ablation probe.

  • The method involves defining an ultrahigh-power ultrashort-duration (UPUD) ablation protocol.
  • The protocol specifies an ablation signal with a target ablation power of at least 400 watts and a pulse duration not exceeding three seconds.
  • The ablation signal is applied to the tissue using an ablation probe.
  • The ablation signal delivered through the probe follows the UPUD protocol, providing the specified target ablation power and duration.

Potential Applications:

  • Tissue ablation for medical procedures such as tumor removal or treatment of abnormal tissue growth.
  • Ablation of cardiac tissue for the treatment of arrhythmias.
  • Ablation of liver tissue for the treatment of liver tumors.

Problems Solved by this Technology:

  • Precise and controlled tissue ablation, allowing for targeted treatment.
  • Minimally invasive procedure compared to traditional surgical methods.
  • Reduced risk of damage to surrounding healthy tissue.

Benefits of this Technology:

  • Faster and more efficient tissue ablation due to the ultrahigh-power ultrashort-duration (UPUD) ablation protocol.
  • Reduced procedure time and patient discomfort.
  • Improved accuracy and precision in creating specific lesions in the tissue.
  • Minimized risk of complications and improved patient outcomes.


Original Abstract Submitted

a method of body tissue ablation includes defining an ultrahigh-power ultrashort-duration (upud) ablation protocol that specifies an ablation signal having (i) a target ablation power of at least 400 watts and (ii) a pulse duration that does not exceed three seconds, for creating a specified lesion in tissue in a body of a patient. contact is made between an ablation probe and the tissue. using the ablation probe, the ablation signal is applied to the tissue according to the upud protocol, which delivers the ablation signal having the specified target ablation power and duration.
