Abstract
A method for performing cryotherapy on a target tissue region in a body includes positioning a first cooling element in a first location in a body adjacent a target tissue region, positioning a second cooling element in a second location in the body adjacent the target tissue region, and cooling the respective first and second cooling elements so as to cool the target tissue region.
Claims42
A method for performing cryotherapy on a target tissue region in a body, comprising:
- positioning a first cooling element in a first location in a body adjacent a target tissue region;
- positioning a second cooling element in a second location in the body adjacent the target tissue region;
- and
- cooling the respective first and second cooling elements so as to cool the target tissue region.

A method for treating atrial fibrillation, comprising:
- positioning a first cooling element in a patient's coronary sinus adjacent a target tissue region at least partially connecting the patient's left atrium and left ventricle;
- positioning a second cooling element in the patient's left atrium adjacent the target tissue region;
- and
- cooling the respective first and second cooling elements so as to ablate the target tissue region.
1 more element
Apparatus for performing cryotherapy on a target tissue region in a body, comprising:
- a first cooling element configured for positioning in a first location in a body adjacent a target tissue region, the first cooling element comprising a locatable portion;
- a second cooling element configured for positioning in a second location in a body adjacent the target tissue region, the second cooling element comprising a locatable portion;
- each of the first and second cooling elements being in fluid communication with a coolant source;
- and
- one or more controllers for controlling cooling of the first and second cooling elements independent of each other.
