Abstract: A medical device for sympathetic nerve ablation may include an elongate shaft and an expandable member. A printed ablation electrode assembly may be disposed on an outer surface of the expandable member, the printed ablation electrode assembly including a positive electrical pathway and a ground electrical pathway printed directly on the outer surface of the expandable member. A temperature sensor may be printed directly on the outer surface of the expandable member. A method of manufacturing a medical device for sympathetic nerve ablation may include printing a conductive ink network directly on a surface of a polymeric balloon material in a flat configuration, printing at least one temperature sensor directly on the surface of the polymeric balloon material, forming the polymeric balloon material into an inflatable balloon, and attaching the inflatable balloon to an elongate catheter shaft.

Abstract: Catheter systems and methods for determining blood flow rates based on light reflection measurements. The catheter may include a lumen extending between a proximal end of the catheter and a distal end of the catheter. The catheter may include fluid infusion openings at the distal end region of the catheter that are configured to permit the indicator fluid to exit the catheter from the lumen. The catheter system may include an optical fiber having one or more sensors thereon for sensing light reflected by blood particles in a body vessel lumen. A blood flow rate may be determined based on the sensed light reflected by blood particles in the body vessel lumen.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include an elongate tubular member having a proximal region, a distal region, and a slot formed in the tubular member between the proximal region and the distal region. The proximal region of the tubular member may be configured to shift between a first configuration and a collapsed configuration. The guide extension catheter may also include an elongate shaft for shifting the proximal region between the first configuration and the collapsed configuration.
