Abstract
A delivery device is disclosed, which may include a needle and at least one deployable electrode retractable into the needle in a retracted geometry that may be substantially straight. The at least one deployable electrode may be operatively connectable to a radiofrequency energy source for delivery of radiofrequency energy. At least a distal portion of the at least one electrode may be deployable, from the needle in a lateral direction relative to a longitudinal axis of the needle, to a deployed geometry that may include at least one radius of curvature in three planes. The deployed geometry may include a helical portion.
Claims19
A delivery device, comprising:
- a needle;
- and
- at least one deployable electrode retractable into the needle in a retracted geometry that is substantially straight,
- wherein the at least one deployable electrode is operatively connectable to a radiofrequency energy source for delivery of radiofrequency energy, at least a distal portion of the at least one electrode is deployable, from the needle in a lateral direction relative to a longitudinal axis of the needle, to a deployed geometry that comprises at least one radius of curvature in three planes.
A delivery device, comprising:
- a skin puncturing means;
- and
- at least one electrode retractable into the puncturing means in a retracted geometry,
- wherein the at least one electrode is operatively connectable to a radiofrequency energy source, at least a distal portion of the at least one electrode is deployable from the puncturing means to a deployed geometry that comprises at least one radius of curvature in two or more planes.
A method of delivery, comprising:
- providing a delivery device that comprises a skin puncturing means and at least one electrode retractable in a substantially straight geometry within the puncturing means, wherein the at least one electrode is operatively connectable to a radiofrequency energy source;
- and
- deploying at least a distal portion of the at least one electrode from the puncturing means so that the deployed distal portion comprises at least one radius of curvature in two or more planes.
