Abstract
An apparatus comprises a catheter, a conductive element and a balloon. The catheter has a lumen. The conductive element is disposed along the catheter. The balloon has an interior in fluid communication with the lumen of the catheter. The balloon is formed of a conductive material conductively coupled to the conductive element. The balloon has a collapsed configuration and an expanded configuration.
Claims17
An apparatus, comprising
- a catheter having a lumen;
- a conductive element disposed along the catheter;
- and
- a balloon having an interior in fluid communication with the lumen of the catheter, the balloon having a first layer formed at least in part of a conductive material conductively coupled to the conductive element, the balloon having a collapsed configuration and an expanded configuration, at least a portion of the balloon including a second layer and a third layer, the second layer being formed of an insulation material, the third layer being formed at least in part of a conductive material.
A method for operating a catheter having a balloon in communication with the catheter, comprising:
- percutaneously disposing the balloon while in a collapsed configuration into a tissue cavity previously-formed by removal of a tissue mass, the balloon being formed of a conductive material;
- expanding the balloon into an expanded configuration, the balloon in the expanded configuration having a shape associated with a shape of the previously-formed tissue cavity;
- and
- applying a radio-frequency signal to the conductive portion of the balloon.
A apparatus for treating a margin tissue associated with a tissue cavity after removal of a tissue mass, comprising:
- a tubular member defining a lumen;
- and
- a balloon having at least one electrode and defining an interior in fluid communication with the lumen of the tubular member, the balloon having a range of configurations including an expanded configuration corresponding to the tissue cavity and a collapsed configuration,
- the at least one electrode being disposed within a first layer of balloon, the balloon further including a second layer and a third layer, the second layer of the balloon being formed of an insulation material, the third layer of the balloon being formed of its own at least one electrode.
