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.
Claims20
A medical device, comprising:
- an elongate catheter body including a proximal portion coupled to a handle and a distal portion;
- a cryogenic treatment region coupled to the distal portion of the catheter body;
- and
- a radiofrequency treatment region defining an outer surface of and a distal tip of the medical device, an entirety of the radiofrequency treatment region coupled to the distal portion of the catheter body at a location that is distal to the cryogenic treatment region.

A medical system, comprising:
- a medical device, the medical device including:
- an elongate catheter body including a proximal portion coupled to a handle and a distal portion;
- an expandable cryogenic treatment region coupled to the distal portion of the catheter body;
- a radiofrequency treatment region defining an outer surface of and a distal tip of the medical device, an entirety of the radiofrequency treatment region coupled to the distal portion of the catheter body at a location that is distal to the expandable cryogenic treatment region, the radiofrequency treatment region having a flexibility;
