Center fed dipole for use with tissue ablation systems, devices and methods
First Claim
1. A device comprising an antenna configured for delivery of energy to a tissue, wherein a distal end of said antenna comprises a center-fed dipole component comprising a rigid hollow tube encompassing a conductor, wherein said conductor has a proximal end and a distal end, wherein said distal end of said conductor engages said rigid hollow tube via connection with the center of a conductive material that spans across said rigid hollow tube thereby preventing said distal end of said conductor from contact with said rigid hollow tube, wherein said distal end of said conductor does not extend beyond said conductive material thereby preventing said conductor from contact with said tissue, wherein said hollow tube has a diameter equal to or less than a 16-gauge needle, wherein said energy is microwave energy.

Abstract
The present invention relates to systems and devices for delivering energy to tissue for a wide variety of applications, including medical procedures (e.g., tissue ablation, resection, cautery, vascular thrombosis, treatment of cardiac arrhythmias and dysrhythmias, electrosurgery, tissue harvest, etc.). In particular, the present invention relates to systems and devices for the delivery of energy employing a center fed dipole component. In certain embodiments, methods are provided for treating a tissue region (e.g., a tumor) through application of energy with the systems and devices of the present invention.
