Abstract
A device for penetrating tissue includes an elongated element having a distal end, a proximal end, a body extending between the distal and the proximal ends, and a lumen located within at least a portion of the body, wherein the lumen has a cross-sectional shape that is a polygon. A device for penetrating tissue includes an elongated element having a distal end, a proximal end, and a body extending between the distal and the proximal ends, at least a portion of the body having a cross-sectional profile that is a polygon, wherein the elongated element is a cannula.
Claims9
A medical device, comprising:
- an elongated probe shaft having a proximal end and a distal end;
- a plurality of needle-shaped electrodes carried by the distal end of the elongated probe shaft, the plurality of needle-shaped electrodes each including a shaft and a fluid delivery lumen extending within the electrode shaft, the fluid delivery lumen having a polygonal cross-sectional shape, and the shaft having an exterior cross-sectional profile that is circular along its entire length;
- and
- a radio frequency generator operatively coupled to the plurality of needle-shaped electrodes.
