Abstract
In one embodiment, the disclosure is directed to an integrated apparatus for delivering energy to a tissue. The integrated apparatus included a housing having a distal end and a tubular structure located within the housing forming a first annulus between the tubular structure and the housing. The tubular structure is configured to accept an energy delivery component and is configured to form a second annulus between the tubular structure and the energy delivery component. The first annulus and the second annulus are configured to communicate with each other proximate to the distal end of the housing.

- and
- a tubular structure located within the housing forming a first annulus between the tubular structure and the housing, the tubular structure configured to accept an energy delivery component and configured to form a second annulus between the tubular structure and the energy delivery component, the first annulus and the second annulus configured to communicate with each other proximate to the distal end of the housing.
An integrated apparatus for delivering energy to a tissue, the integrated apparatus comprising:
- a housing having a distal end;
- a coupling assembly to interface with the housing opposite the distal end, the coupling assembly comprising a first fluid access port and a second fluid access port, the first fluid access port associated with a first annulus and the second fluid access port associated with a second annulus, the coupling assembly comprising an opening for introducing an energy delivery component;
- and
- a tubular structure located within the housing forming the first annulus between the tubular structure and the housing, the tubular structure configured to form the second annulus between the tubular structure and the energy delivery component, the first annulus and the second annulus configured to communicate with each other proximate to the distal end of the housing.
An energy delivery system comprising
- an energy source;
