TREATMENT ADJUSTMENT BASED ON TEMPERATURES FROM MULTIPLE TEMPERATURE SENSORS

摘要

According to some embodiments, a medical instrument (for example, an ablation device) comprises an elongate body having a proximal end and a distal end, an energy delivery member positioned at the distal end of the elongate body, a first plurality of temperature-measurement devices carried by or positioned within the energy delivery member, the first plurality of temperature-measurement devices being thermally insulated from the energy delivery member, and a second plurality of temperature-measurement devices positioned proximal to a proximal end of the energy delivery member, the second plurality of temperature-measurement devices being thermally insulated from the energy delivery member.

1. A system for adjusting one or more treatment parameters based on temperature measurements received from a plurality of temperature sensors, the system comprising:
a radiofrequency energy source configured to provide energy to a combination electrode assembly of an ablation catheter through one or more conductors extending from the radiofrequency energy source to the combination electrode assembly, the combination electrode assembly comprising a distal member positioned at a distal tip of the ablation catheter and a proximal member spaced apart from the distal member by a gap; a hardware processor configured to, upon execution of instructions stored on a computer-readable storage medium:
receive signals from a distal group of temperature sensors positioned along the distal member of the combination electrode assembly;receive signals from a proximal group of temperature sensors positioned along the proximal member of the combination electrode assembly;determine temperature measurements for each of the temperature sensors of the distal group based on the signals received from the distal group of temperature sensors;determine temperature measurements for each of the temperature sensors of the proximal group based on the signals received from the proximal group of temperature sensors; andadjust one or more treatment parameters based on the temperature measurements.
