Energy Delivery Device and Methods of Use

摘要

The present disclosure is directed to an expandable energy delivery assembly adapted to deliver electrical energy to tissue. The assembly includes an elongate device including an irrigation shaft defining a irrigation lumen fluidly couplable to an irrigation source and a rapid exchange shaft defining a guidewire lumen configured for reception and passage of a guidewire. The assembly also includes an inflatable element that is secured to the elongate device. The inflatable element includes a double helical electrode disposed on the inflatable element that makes between about 0.5 to about 1.5 revolutions around the inflatable element.

1. An expandable energy delivery assembly adapted to deliver electrical energy to tissue, the assembly comprising:
an elongate device comprising:
an irrigation shaft having a proximal end and a distal end and defining an irrigation lumen fluidly couplable to an irrigation source at the proximal end of the irrigation shaft;a rapid exchange shaft having a proximal end and a distal end and defining a guidewire lumen configured for reception and passage of a guidewire, the proximal end of the rapid exchange shaft overlaps the distal end of the irrigation shaft; and an inflatable element having a proximal end and a distal end, the proximal end of the inflatable element is secured to the elongate device where the proximal end of the rapid exchange shaft overlaps the distal end of the irrigation shaft and the distal end of the inflatable element is secured to the elongate device at the distal end of the rapid exchange shaft, the inflatable element including a double helical electrode disposed on the inflatable element, the double helical electrode making between about 0.5 to about 1.5 revolutions around the inflatable element.
