Abstract

A catheter including a coil guide that assist with the proper installation of an antenna for the delivery of microwave energy on a catheter. The coil guide secures the antenna in the proper position and shape while the catheter is navigated to the targeted tissue. The coil guide includes a channel that is molded or cut into the coil guide for receiving the antenna and maintaining proper position of the antenna. The channel provides a guide for medical personnel when wrapping the antenna coils onto the catheter body and secures the antenna in the proper shape and position while the catheter is being navigated to the targeted tissue. Alternatively, the antenna can be pre-coiled for installation into the channel. The coil guide can be adhesively attached or overmolded proximate a distal end of a catheter body.
