Ablation systems incorporating the device and methods of using the device are also provided.
Claims55
A sensing apparatus for monitoring temperature generated by an ablation apparatus on organic tissue, comprising:
- a temperature-sensing pad;
- and
- an output device in communication with the pad, the output device operatively adapted to receive and display a representation of a lesion found on the organic tissue.
A system for assessing transmurality of an ablation in a tissue comprising:
- an ablation apparatus operatively adapted to ablate a first side of the tissue;
- a temperature-sensing pad operatively adapted to sense temperature along a second side of the tissue;
- and
- an output device in communication with the pad, the output device operatively adapted to indicate the temperature of the tissue.
A method of ablating organic tissue comprising the steps of:
- providing a temperature-sensing pad operatively adapted to sense a temperature of the tissue and an output device in communication with the pad, the output device operatively adapted to display a representation of a lesion found on a back side of the tissue;
- positioning the pad against a back side of the tissue;
- ablating the tissue with an ablation apparatus against a front side of the tissue;
- sensing the temperature changes of the ablated tissue with the pad;
- and
- ablating the tissue in accordance with the temperature changes.
An apparatus for monitoring temperature generated by an ablation apparatus on organic tissue comprising:
- a temperature sensing pad incorporating a plurality of temperature-sensing liquid crystals therein;
- and
- an output device in communication with the pad, the output device operatively adapted to receive and display a representation of a lesion found on the organic tissue.
An apparatus for monitoring temperature generated by an ablation apparatus on organic tissue comprising:
- a finger pad comprising a plurality of temperature-sensing elements therein, the finger pad formed to conform to a finger;
- and
- an output device in communication with the finger pad, the output device operatively adapted to receive and display a representation of a lesion found on the organic tissue.
A system for assessing transmurality of an ablation in a tissue comprising:
- an ablation apparatus operatively adapted to ablate a first side of the tissue;
- a temperature-sensing pad operatively adapted to sense temperature along a second side of the tissue;
- a conductive element attached to the pad;
- and
- an output device in communication with the pad, the output device operatively adapted to indicate the temperature of the tissue.
An ablation system for creating a tissue ablation site, the system comprising:
- an energy source;
- an ablation device operatively coupled to the energy source, the ablation device comprising one or more energy transfer elements positioned along a tissue contact surface of the ablation device;
- and
- a sensor device operatively coupled to the energy source, the sensor device including a sensor adapted to sense a temperature parameter relating to the tissue ablation site, the sensor device having a tissue contact surface, one or more suction openings positioned along the tissue contact surface of the sensor device, and a suction conduit for providing suction from a suction source to the one or more suction openings, the suction conduit being operatively connected with the one or more suction openings.
