AI Technical Summary

Benefits of technology

The present disclosure provides an expandable energy delivery assembly for delivering electrical energy to tissue. The assembly includes an irrigation shaft, a rapid exchange shaft, and an inflatable element. The inflatable element has a double helical electrode with a proximal electrode and a distal electrode. The assembly also includes a first conductive layer and a second conductive layer on the irrigation shaft, a first insulation layer, a second insulation layer, and a third conductive layer on the first insulation layer. The inflatable element has at least one irrigation aperture and the double helical electrode is electrically coupled to the inflatable element. The assembly can be manufactured using a conductive material and insulation materials on the irrigation shaft and the rapid exchange shaft. The technical effect of the invention is to provide an improved energy delivery assembly for tissue ablation that includes an inflatable element with a double helical electrode for better tissue penetration and improved energy delivery.

Problems solved by technology

Abstract

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.
