Abstract
A medical device is provided and includes an elongated tube that has a longitudinal axis and an expandable member attached to the tube. The expandable member is expandable from a collapsed configuration to an expanded configuration. A plurality of electrodes is attached to the expandable member. The electrodes are used to emit energy. Each of the electrodes is arranged generally coaxially relative to the tube when the expandable member is in its collapsed and expanded configurations.
Claims27
A medical device used for thermal treatment of tissue, comprising an elongated tube having a longitudinal axis;
- an expandable member attached to said elongated tube, said expandable member being expandable from a collapsed configuration to an expanded configuration;
- and a plurality of energy-emitting electrodes attached to said expandable member such that each of said electrodes is arranged generally coaxially relative to said tube when said expandable member is in its said collapsed and expanded configurations.
A method for performing thermal treatment of tissue using a medical device which includes a tube, an expandable member attached to the tube and expandable from a collapsed configuration to an expanded configuration, and a plurality of electrodes attached to the expandable member, said method comprising the steps of:
- (a) inserting the medical device within a tissue area with the expandable member in its collapsed configuration, in which the electrodes are in close proximity to each other and in which all of the electrodes are arranged generally coaxially relative to the tube;
- and
- (b) expanding the expandable member so that it assumes its expanded configuration, in which the electrodes are spaced apart from each other and, in which all of the electrodes are arranged generally coaxially relative to the tube.
