摘要： A medical device and related methods of use or manufacture are disclosed. The medical device may include an intravascular catheter for nerve modulation. The medical device includes an elongate shaft having a proximal end region, a distal end region, and a lumen extending therebetween. An expandable member is coupled to the distal end region of the elongate shaft. One or more electrical conductors extend from the proximal end region of the elongate shaft to the expandable member. The one or more electrical conductors may have a distal end region secured directly to an outer surface the expandable member. One or more energy delivery regions are positioned on the expandable member and coupled to the one or more electrical conductors.

摘要： A balloon for renal nerve modulation is disclosed. The balloon may include a polymer material forming a balloon wall having an outer surface and flexible circuits comprising a base selectively adhered to the exterior surface of the balloon wall. Adhesive is selectively applied to the outer surface of the balloon, to the flexible circuit or to both such that the adhesive is selectively deposited on the at least a portion of the at least two pads or on the at least a portion of the at least two pads and to a portion of the distal spline. The portion of the at least two pads or the portion of the at least two pads and a portion of the distal spline are adhered to the outer surface of the balloon and a remainder of the flexible circuit moves freely with respect to the outer surface of the balloon.

摘要： A catheter system is disclosed. An example catheter system includes an elongate tubular member having a distal region and a proximal end, a first balloon disposed along the distal region of the tubular member, a second balloon disposed along the distal region of the tubular member, wherein the second balloon is spaced from the first balloon. The catheter system also includes a first lumen extending within the elongate tubular member, a second lumen extending within the elongate tubular member, a first set of apertures in fluid communication with the first lumen, wherein the first set of apertures are configured to inflate both the first balloon and the second balloon and a second set of apertures in fluid communication with the first lumen, wherein the second set of apertures are configured to apply a treatment to a target site positioned between the first balloon and the second balloon.
