Rotation Mechanism for Bipolar and Monopolar Devices

Abstract

An electrosurgical device and a method of orienting the electrosurgical device are provided. The device includes a rotation mechanism including a first and a second connector where the first connector is rotatable relative to the second connector. The device also includes a handle operably connected to the first connector; and a catheter operably connected to the second connector where the handle is rotatable relative to the catheter. The device further includes a first wire having a distal portion anchored to a distal portion of the catheter so that the distal portion of the wire is orientable by rotation of the handle relative to the catheter. At least one of the rotation mechanism or a proximal portion of the wire forms a conductive connection that operably connects a power source to the distal portion of the first wire to energize the distal portion of the first wire in the electrosurgical device.

1 . A method of orienting a distal portion of a wire of an electrosurgical device, the method comprising:
 operably connecting a proximal portion of the wire to a handle of the electrosurgical device;   anchoring the distal portion of the wire to a distal portion of a catheter of the electrosurgical device;   connecting a first connector having a conducting region to the handle,   connecting a second connector having a conducting region to the catheter so that the first connector rotates relative to the second connector to form a rotatable conducting section of the electrosurgical device; a proximal portion of the wire forming a conductive connection that operably connects a power source to the distal portion of the wire to energize the distal portion of the wire, the wire comprising a first electrode and the rotatable conducting second comprising a second electrode;   rotating the handle relative to the catheter to orient the distal portion of the wire.   
     
     
         2 . The method according to  claim 1 , further comprising providing a friction source to the first and second connectors to control the torque required to rotate the handle relative to the catheter. 
     
     
         3 . The method of  claim 2 , further comprising conductively isolating the first electrode from the second electrode.
