Abstract
Structures for treating tissue with high-frequency energy, methods of making a structure for treating tissue with high-frequency energy, and methods of treating tissue with high-frequency energy. A structure for use in treating tissue may include multiple microblades composed of an electrical conductor. Each of the microblades may include a shaft and a tip arranged adjacent to an end of the shaft. The tip includes multiple surfaces that surround a solid core of the tip and at least two of the surfaces may taper toward the end of the shaft.
Claims20
A structure comprising:
- a plurality of microblades comprised of an electrical conductor, each of the plurality of microblades including a shaft and a tip adjacent to an end of the shaft, the tip including a plurality of surfaces arranged to surround a solid core of the tip, and at least two of the plurality of surfaces tapering toward the end of the shaft.
A method comprising:
- applying an etch mask to a plate;
- and
- etching first portions of the plate that are unmasked by the etch mask with an etching process to completely remove the first portions of the plate,
- wherein the plate includes second portions that are masked by the etch mask during the etching process, the second portions include a plurality of microblades each having a shaft and a tip adjacent to an end of the shaft, and the tip includes a plurality of surfaces at least two of which taper toward the end of the shaft.
A treatment method comprising:
- inserting respective tips of a plurality of microblades arranged in a rhombus-shaped pattern to a given depth into tissue;
- energizing the plurality of microblades in alternating rows of the rhombus-shaped pattern with opposite polarities of radio-frequency energy, and
- treating the tissue with the radio-frequency energy delivered from the respective tips of the plurality of microblades.
