Apparatus and systems are disclosed that incorporate a steerable catheter control handle for bi-directional control of a steerable catheter. The steerable catheter control handle includes a slide assembly positioned within the inner housing and operable to translate linearly therein. The control handle further includes a proximal portion of at least two control wires being positioned through the slide assembly wherein one of the at least two control wires is indirectly coupled to the slide assembly via a direction reversing element. The steerable catheter control handle has a control knob rotatably coupled to the housing for linearly translating the slide assembly, thereby enabling the slide assembly to manipulate each of the at least two control wires, effecting a change in deflection of said catheter. The slide assembly further comprises a slide limiting mechanism to restrict linear translation of the slide assembly.

Steerable medical device handle

A steerable catheter control handle and method are provided for bi-directional control of a steerable catheter, the catheter including at least two control wires, a distal end of each of the control wires being coupled to the catheter at a distal region thereof. The control system comprises a housing. A wire actuation mechanism is disposed within the housing and is operably coupled to at least two control wires for enabling actuation of the at least two control wires. The steerable catheter control handle additionally comprises a proximal control knob that is operably coupled to the wire actuation mechanism to enable actuation of the at least two control wires for causing a distal end deflection of the steerable catheter.

Embodiments of a steerable catheter control system and methods are disclosed. The steerable catheter control system comprises a housing which defines an inner housing and a slide assembly which linearly translates within the inner housing. At least two control wires are positioned through the slide assembly wherein one of the at least two controls wires are indirectly coupled to the slide assembly via the direction reversing element. The steerable catheter control system further comprises a slack limiting element, coupled to at least one of the at least two control wires. The slack limiting element allows for frictional engagement of the control wire to limit slack. The control system includes a control knob for linearly translating the slide assembly, enabling the slide assembly to manipulate the control wires which causes a change in deflection of the steerable catheter.

A control system and method are provided for control of a steerable catheter, the catheter including at least two control wires, a distal end of each of the control wires being coupled to the catheter at a distal region thereof, the control system comprising: a housing coupled to the catheter; a slide assembly positioned within the housing and operable to translate linearly therein; a proximal portion of each of the at least two control wires being positioned through the slide assembly; and a control knob rotatably coupled to the housing for linearly translating the slide assembly, thereby enabling the slide assembly to separately manipulate each of said at least two control wires to effect a change in a deflection of said catheter.

A wire actuation mechanism is disposed within the housing and is operably coupled to at least two control wires for enabling actuation of the at least two control wires. The steerable catheter control handle additionally comprises a proximal control knob that is operably coupled to the wire actuation mechanism to enable actuation of the at least two control wires. The control knob is positioned proximal to the wire actuation mechanism to enhance ease of use of the steerable catheter control handle. The rotation of the proximal knob causes movement of the wire actuation mechanism within the housing for tensioning one of the at least two control wires for causing a distal end deflection of the steerable catheter.

A method is disclosed for the treatment of a thoracic region of a patient's body. Embodiments of the method comprise positioning an energy delivery portion of an electrosurgical device to face a segment of a thoracic vertebra at a distance from the segment; and cooling the energy delivery portion and delivering energy through the energy delivery portion.

An elongate member for inserting into a cannula is disclosed. The cannula comprises an electrically insulated region and an electrically exposed conductive region for delivering energy to form a lesion within a patient's body at an intended location relative to the electrically exposed conductive region. The elongate member is structured to cooperatively engage with the cannula at a pre-determined insertion depth and to provide a variation in radiopacity, at a pre-determined position relative to the electrically exposed conductive region, when inserted to the pre-determined insertion depth. The variation in radiopacity provides a visual reference for distinguishing, using fluoroscopic imaging, the intended location of the lesion.
