Methods and systems of temperature based alarms and/or automatic interrupt (shutoff) during a cardiac ablation procedure

A system for activating alarm(s) and/or interrupting energy delivery during a cardiac ablation procedure, comprises:

• an esophageal temperature probe with more than one temperature sensing members;
• an interface electronics for providing information from said temperature sensing member(s) into a cardiac monitoring/recording system or a cardiac mapping system;
• said cardiac monitoring/recording system or a cardiac mapping system configured and programmable for detecting at least one predetermined event(s) based on temperature parameter(s) levels of said at least one sensing member and capable of activating alarm(s) and/or interrupt or pause energy delivery for said ablation;
• and
• means for activating alarms and/or interrupt or pause energy delivery based on pre-determined temperature wherein, said activating alarms and/or interrupt or pause of energy delivery is based on a command signal from said electrophysiology monitoring/recording system or a cardiac mapping system and wherein, said interface electronics is also used for interrupt or pause of energy delivery for said ablation procedure.

A system for activating alarm(s) and/or interrupting energy delivery during a cardiac ablation procedure, comprises:

• an esophageal temperature probe wherein said temperature probe comprises one or more locations on said probe for sensing temperature;
• a computer based system comprising a processor and software configured and programmed for detecting at least one pre-determined esophageal temperature parameter level(s) selectable by an operator, and capable of initiating alarm(s) and/or energy delivery interrupt, based on reaching said at least one pre-determined level(s) of temperature parameter(s) of said esophageal temperature probe, wherein said computer based system is part of a cardiac monitoring/recording system which may be one of one of GE's CardioLab® system, St Jude's EP Workmate® systems, CR Bard's LabSystem™ PRO, or any FDA approved cardiac monitoring/recording system;
• and
• energy delivery interrupt means for activating alarms and/or energy delivery interrupt based on reaching pre-determined temperature parameters which is based on a command signal from said cardiac monitoring/recording system.
