    摘要: An ablation catheter apparatus with a monopole antenna that is arranged to provide a relatively uniform electric field and a method for using such an ablation catheter apparatus are disclosed. According to one aspect of the present invention, an ablation catheter includes an elongated flexible tubular member that is adapted to be inserted into the body of a patient, and a transmission line that is disposed within the tubular member. The transmission line has a distal end and a proximal end which is arranged to be connected to an electromagnetic energy source. The catheter also includes a monopole antenna with tip section and a body section that includes a distal end and a proximal end. The tip section and the body section are arranged to produce a relatively uniform electric field around the monopole antenna which is sufficiently strong to cause tissue ablation. The proximal end of the body section of the monopole antenna is arranged to be electrically coupled to the transmission line.

    摘要: A microwave ablation instrument including a transmission line having a first conductor and a second conductor suitable for the transmission of microwave energy. A horn antenna device is mounted to the end of the transmission line, and include an outer conductor and an inner conductor. The outer conductor of the horn antenna is electrically coupled to the second conductor of the transmission line, and includes a peripherally extending interior wall flaring outwardly to define a recess therein. The inner conductor of the horn antenna is electrically coupled to the first conductor of the transmission line and terminates in the outer conductor recess. The inner conductor and the outer conductor cooperate to emit an electromagnetic field sufficiently strong to cause tissue ablation in a direction generally away from the flared interior wall of the outer conductor.

    摘要: The present invention discloses devices and methods for creating multiple lesions using ablation devices in anatomical regions such as the heart, for example to treat cardiac arrhythmias. The present invention discloses methods and devices to create continuous lesions using area ablation devices. The present invention discloses various embodiments of reference assemblies for accurately positioning ablation devices having ablating portions, especially deployable ablation portions adapted for area ablation. The ablation devices are positioned using the reference assemblies in the anatomy to create one or more lesions. The present invention also discloses several method embodiments for creating continuous lesions using deployable ablating portions to produce two or more overlapping lesions.
