Balloon catheters with flexible conducting wires and related methods of use and manufacture

A medical device, the medical device comprising:

• an elongate shaft having a proximal end region, a distal end region, and a lumen extending therebetween;
• an inflatable cylindrical balloon coupled to the distal end region of the elongate shaft;
• and
• one or more wire conductors having a proximal end and a distal end and covered with an insulating material, the one or more wire conductors extending from the proximal end region of the elongate shaft to an outer surface of the inflatable cylindrical balloon, wherein at least a portion of the one or more wire conductors is wound in a serpentine manner and is free from the insulating material defining one or more energy delivery regions adjacent the distal end of the one or more wire conductors and wherein the at least the portion of the one or more wire conductors is wound in the serpentine manner extending along a length of the inflatable cylindrical balloon.

A medical device, comprising:

• an elongate shaft having a proximal end region, a distal end region, and a lumen extending therebetween;
• an inflatable cylindrical balloon coupled to the distal end region of the elongate shaft;
• one or more round wire conductors having a proximal end and a distal end and covered with an insulating material, the one or more round wire conductors extending from the proximal end region of the elongate shaft to the inflatable cylindrical balloon, wherein at least a portion of the one or more round wire conductors is wound in a serpentine manner and free from the insulating material defining one or more energy delivery regions adjacent the distal end of the one or more wire conductors;
• and
• one or more temperature sensors positioned adjacent to at least one of the one or more energy delivery regions;
• wherein the one or more energy delivery regions comprise at least two energy delivery regions and wherein the at least two energy delivery regions are arranged in bipolar pairs and wherein the at least the portion of the one or more round wire conductors is wound in the serpentine manner extending along a length of the inflatable cylindrical balloon.
