Patent number: 9445858Abstract: A bipolar electrosurgical device is disclosed. The bipolar electrosurgical device includes a handle having a shaft and a distal end. The handle can be coupled to a source of electrical energy and a fluid source. A U-shaped first electrode extends distally in a plane from a pair of openings on the distal end of the shaft. The first electrode is in electrical communication with one of an active pole or a return pole of the source of electrical energy. A longitudinal second electrode extends distally from a middle opening on the distal end of the shaft. The second electrode is coplanar to the first electrode and electrically isolated from the first electrode. The second electrode is in electrical communication with the other of the active pole or the return pole of the source of electrical energy. The second electrode forms a lumen configured to be in fluid communication with the fluid source and a fluid opening for dispersing fluid.Type: GrantFiled: March 5, 2014Date of Patent: September 20, 2016Assignee: MEDTRONIC ADVANCED ENERGY LLCInventors: Brian M. Conley, Jonathan J. Barry, Roger D. Greeley, Chad M. Greenlaw, Lorenzo C. Vaccarella, Joseph Sylvester

Patent number: 9333027Abstract: A method of producing an electrosurgical device is disclosed. Opposing longitudinal clamshells are formed, and each clamshell includes a face having a generally planar major portion. Longitudinal grooves are formed in a clamshell, and an electrical conductor in a disposed in a groove. The faces are aligned to form an electrical passage including the electrical conductor in the groove and a spaced-apart fluid passage with another groove. The clamshells are welded together to form a shaft member such that the electrical passage and the fluid passage are fluid tight along a major longitudinal portion of the shaft. Electrodes are attached to the distal end of the shaft and are in electrical communication with the electrical conductor.Type: GrantFiled: October 3, 2013Date of Patent: May 10, 2016Assignee: MEDTRONIC ADVANCED ENERGY LLCInventors: Eliot F. Bloom, Lorenzo C. Vaccarella, Chad M. Greenlaw, Roger D. Greeley, Steven G. Miller

Patent number: 8920417Abstract: In some embodiments, an electrosurgical device includes a shaft, a first U-shaped electrode at a distal end of the shaft, and a second blade shaped electrode at the distal end of the shaft. The second electrode includes a spherical distal end. And the second electrode is substantially coplanar with the first electrode such that the first electrode surrounds a perimeter of the second electrode. The second electrode is spaced from the first electrode by an aperture. In some embodiments, an electrosurgical device includes a shaft, a first electrode at a distal end of the shaft defining an aperture and comprising a pointed tip, and a second electrode disposed at the distal end of the shaft that is substantially coplanar with the first electrode such that the first electrode surrounds a perimeter of the second electrode. The second electrode is spaced from the first electrode by the aperture.Type: GrantFiled: December 28, 2012Date of Patent: December 30, 2014Assignee: Medtronic Advanced Energy LLCInventors: Brian M.

Publication number: 20110295249Abstract: This invention provides a fluid-assisted electrosurgical device to treat tissue in a presence of radio frequency energy and a fluid provided from the device. The device comprises a handle, a rigid shaft member distal to the handle, and at least one electrode distal to the shaft member. The shaft member comprises a shaft member first body and a shaft member second body joined together along a length of the shaft member. The shaft member further comprises a plurality of longitudinally oriented shaft member passages, with each of the passages having a length defined by the shaft member first body and the shaft member second body.Type: ApplicationFiled: May 28, 2010Publication date: December 1, 2011Applicant: SALIENT SURGICAL TECHNOLOGIES, INC.Inventors: Eliot F.
