Abstract
An intravascular ablation device, including a flexible elongate body; an expandable element positioned on the elongate body; a radiofrequency or electroporation treatment segment located distally of the expandable element; a cryogenic coolant source in fluid communication with an interior of the expandable element; and a radiofrequency or electroporation energy source in communication with the radiofrequency or electroporation treatment segment.
Claims19
A method of treating tissue, the method comprising:
- positioning a medical device proximate a first tissue area, the medical device including:
- an elongate catheter body having a proximal portion and a distal portion;
- an expandable first treatment region coupled to the distal portion of the elongate catheter body;
- and
- a second treatment region coupled to the distal portion of the catheter body at a location that is distal to the expandable first treatment region and defines an outer surface and a distal tip of the medical device;
- activating the expandable first treatment region to create a first treatment pattern in the first tissue area;
- deactivating the expandable first treatment region;
- repositioning the medical device such that the second treatment region is proximate a second tissue area;
- and
- activating the second treatment region to treat a second treatment pattern in the second tissue area, the second treatment pattern being different than the first treatment pattern.

A method of ablating tissue, the method comprising:
- navigating a medical device to a location within a patient's body, the medical device including:
- an elongate catheter body having a proximal portion and a distal portion;
- a first treatment region coupled to the distal portion of the catheter body;
- and
- a second treatment region coupled to the distal portion of the catheter body at a location that is distal to the first treatment region and defines an outer surface and a distal tip of the medical device, the first and second treatment regions being independently operable;
- activating the first treatment region to create a first treatment pattern in a first tissue area;
- repositioning the medical device and deflecting the second treatment region such that the second treatment region is proximate a second tissue area, the second treatment region being deflectable independently of the first treatment region;
- and
- activating the second treatment region to treat a second treatment pattern in the second tissue area, the second treatment pattern being different than the first treatment pattern.
