Appl. No.:

17/849262

Inventors:

- Minneapolis MN, US
Mohammad Miri - Longmont CO, US
Juan Pablo Angulo - Louisville CO, US

International Classification:

A61B 18/14

Abstract:

An electrosurgical device including an elongated body extending from a proximal end to a distal end and defining an evacuation lumen. The elongated body including an irrigation channel carried by the elongate body, the irrigation channel configured to deliver a fluid to a target tissue adjacent to the distal end, a coring electrode at the distal end of the elongated body, where the coring electrode defines an opening to the evacuation lumen, and where the coring electrode is configured to operate in a monopolar configuration to deliver radio frequency (RF) plasma energy to adjacent tissue to cut a volume of the target tissue, and a dielectric coating on at least a distal portion of the elongated body, the dielectric coating electrically insulating the elongated body from target tissue and the volume of cut target tissue, where the dielectric coating comprises a ceramic material.

International Classification:

A61B 18/04
A61B 34/20

Abstract:

A system for altering an energizable instrument for performing a procedure on the subject. The instrument may be tracked during a procedure and a controller may alter operation thereof during the selected procedure. The energizable instrument may have energy provided to a working end to heat a working end to a selected temperature for various procedures such as cutting, coagulation, vaporization, or the like.

International Classification:

A61B 18/14

Abstract:

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion, and a coring electrode positioned at the distal portion of the elongated body, where the coring electrode is at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway.

International Classification:

A61B 18/14
A61B 18/12

Abstract:

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion; a coring electrode at the distal portion of the elongated body, where the coring electrode is positioned at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway; and a powered conveyance mechanism positioned within the internal passageway configured to further cut the volume of the tissue and convey the volume of the tissue proximally within the internal passageway.
