Abstract: Medical devices and methods for making and using the same are disclosed. An example medical device may include a medical device for tissue ablation. The medical device may include an elongated shaft having a distal region. An inflatable balloon may be mounted to the distal region. The inflatable balloon may include a body region, a proximal waist, a distal waist, a proximal cone region, and a distal cone region. A skirt may be attached to the inflatable balloon and may extend proximally from the body region. An electrode assembly may be applied directly to an outer surface of the body region of the inflatable balloon. The electrode assembly may include a first conductive member applied directly to the outer surface of the body region of the inflatable balloon and extending proximally therefrom along an outer surface of the skirt.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a medical device for modulating nerves. The medical device may include an elongate shaft having a distal region. A balloon may be coupled to the distal region. An electrode may be disposed within the balloon. A virtual electrode may be defined on the balloon. The virtual electrode may include a conductive region having an edge and a peripheral region disposed at least partially along the edge of the conductive region. The peripheral region may be configured to dissipate forces, electrical current, or both accumulating along the edge of the conductive region.

Abstract: An intravascular catheter and related methods of use or manufacture are disclosed. The catheter includes an outer tubular member having a proximal end and a distal end, and an inner tubular member having a proximal end and a distal end. An inflatable balloon have a proximal end waist coupled to the outer tubular member adjacent to the distal end thereof, and a distal end waist coupled to the inner tubular member adjacent to the distal end thereof. The balloon includes an interior surface, an exterior surface, and a lumen defined by the interior surface. The balloon further includes at least one section extending from the interior surface of the balloon to the exterior surface of the balloon. A transmitter is disposed about the inner tubular member. In addition to the above, the proximal end waist is coupled to the outer tubular member such that an inflation fluid exits the balloon.

Abstract: Medical devices and methods and making and using medical devices are disclosed. An example medical device may include an elongate shaft having a distal region. An expandable member may be coupled to the distal region. The expandable member may be capable of shifting between a first configuration and an expanded configuration. The expandable member may have a distal portion, a proximal portion, and a body portion disposed between the distal portion and the proximal portion. The body portion may have a projection formed therein that projects radially outward from the body portion. A flexible electrode assembly may be coupled to the projection.
