Abstract
A wearable electrosurgical return electrode includes an outer pad, an inner pad, and a conductive element disposed between the outer pad and the inner pad. The return electrode is formed as a flexible sheath and configured to be worn over at least a portion of a body during use.
Claims21
A wearable electrosurgical return electrode, comprising:
- a sheath comprising an inner pad having an outer surface and an outer pad having an inner surface;
- and
- a conductive element disposable adjacent to the outer surface of the inner pad and the inner surface of the outer pad;
- wherein the wearable electrosurgical return electrode has a generally tubular shape,
- wherein the conductive element, the inner pad, and the outer pad are flexible and elastic so that the wearable electrosurgical return electrode is configured to be secured on and conform to contours of a patient when worn by a patient during use,
- wherein the wearable electrosurgical return electrode is devoid of any externally exposed electrical connectors in electrical contact with the conductive element,
- wherein the conductive element and the inner or outer pad are configured to facilitate a capacitive connection to a capacitive connector of an electrosurgical wave generator separate from the wearable electrosurgical return electrode, and
- wherein inner pad, the outer pad, and the conductive element are separate layers of the wearable electrosurgical return electrode that are not permanently secured together such that each can be donned by a patient independently of one another.
5 more elements
A wearable electrosurgical return electrode, comprising:
- a first pad;
- a second pad;
- and
- a conductive element disposed between the first pad and the second pad, the conductive element comprising a bus bar disposed along an edge thereof, the bus bar having a first major surface facing the first pad and a second major surface facing the second pad, the first major surface being entirely covered by an insulating layer, and at least a portion of the second surface of the bus bar being uncovered by the insulating layer, the uncovered portion of the second surface of the bus bar and the second pad being configured to facilitate a capacitive connection between the bus bar and an electrical connector of an electrosurgical wave generator;
- wherein the conductive element and the first and second pads are flexible so that the wearable electrosurgical return electrode can be worn over and conform to a portion of a patient's body during use,
- wherein the wearable electrosurgical return electrode is devoid of any externally exposed electrical connectors in electrical contact with the conductive element.
3 more elements
An electrosurgical system, comprising:
- wearable electrosurgical return electrode, comprising:
- an outer pad;
- an inner pad;
- a conductive element disposed between the outer pad and the inner pad, the conductive element having a first major surface that is insulated and an opposing second major surface that is at least partially not insulated,
- wherein the wearable electrosurgical return electrode is devoid of any externally exposed electrical connectors in electrical contact with the conductive element;
- and
- a capacitive connector selectively connectable to the wearable electrosurgical return electrode, the capacitive connector being configured to make a capacitive electrical connection through either the inner or outer pad and with the non-insulated portion of the conductive element,
- wherein the wearable electrosurgical return electrode has a generally tubular shape, and
- wherein the wearable electrosurgical return electrode is formed as a flexible and elastic sheath and is configured to be secured on and conform to the contours of at least a portion of a body during use.
