A device for treating spinal tissue of a patient's body may include an energy source and first and second probe assemblies. Each of the probe assemblies may have an electrically conductive energy delivery device electrically coupled to the energy source, and may also have an electrothermal device for cooling the probe assembly. The device is configured so that the energy source delivers energy to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue while the electrothermal devices cool the probe assemblies. Related methods of use include cooling, at times via an electrothermal device.

Electrosurgical tissue treatment device

A novel medical probe assembly, system, and methods for the use thereof to treat tissue are described. The system optionally comprises an energy source, two probe assemblies, and one or more cooling devices to provide cooling to at least one of the probe assemblies. The probe assemblies may be configured in a bipolar mode, whereby current flows preferentially between the probe assemblies. The probe assemblies and system described herein are particularly useful to deliver radio frequency energy to a patient's body. RF energy delivery may be used for various applications, including the treatment of pain, tumor ablation and cardiac ablation.

Electrosurgical device for treatment of tissue

Electrosurgical tissue treatment method and device

A method of treating spinal tissue of a patient's body is disclosed, the method using a system comprising an energy source and first and second internally-cooled probe assemblies, wherein each of the probe assemblies comprises an electrically conductive energy delivery device electrically coupled to the energy source. The method comprises: inserting the energy delivery devices of the first and second internally-cooled probe assemblies into spaced-apart treatment sites for the spinal tissue; delivering energy from the energy source to the spinal tissue through the energy delivery devices to create a lesion within the spinal tissue; delivering a cooling fluid to the energy delivery devices; and controlling the delivery of energy and the delivery of the cooling fluid to the energy delivery devices such that the lesion extends between the energy delivery devices.

Electrosurgical tissue treatment method

The invention comprises a method for introduction of materials into a patient's body. The method generally comprises providing an elongate member for introducing the material. The elongate member defines a lumen and comprises a distal end defining an aperture and a proximal end. The method further comprises the steps of positioning the elongate member at a target site of a patient's body; providing a motorized device at least partially disposed within the lumen; and introducing the material through the lumen into the target site using the motorized device.

Method of and device for introducing materials into a body

Method for introducing materials into a body

The invention comprises a method for removal of bone marrow tissue from a patient's body. The method generally comprises the steps of providing an apparatus comprising an elongate member for receiving bone marrow tissue. The elongate member defines a lumen and comprises a distal end defining an aperture and a proximal end. The apparatus further comprises an elongate tissue removal member for conveying bone marrow tissue through the lumen. The tissue removal member is rotatably disposed within the lumen. The method further comprises gathering a sample of said tissue into said lumen; and conveying with said tissue removal member at least a portion of the tissue sample proximally along said lumen. The step of gathering may be accomplished by advancing the apparatus through the tissue.

Method for removing material from a patient's body

A treatment method is disclosed for treating a bodily tissue utilizing one or more steps of removal of material as well as one or more steps of energy delivery in order to effectively treat the bodily tissue. These mechanisms of treatment may beneficially be used to induce separate treatment effects, for example to treat both the symptoms and the underlying cause of a specific pathological condition. In addition, a specific application of the inventive method is described for using the inventive method to treat an intervertebral disc.

Method of treating biological tissue

An electrosurgical apparatus comprising an energy source operable to concurrently provide a first signal and a second signal, said first and second signals having different frequencies; and a signal processor operable to receive a third signal from a patient's body, to process said third signal, and to produce an output based on a processing of said third signal; wherein said third signal is an evoked potential generated by said patient's body in response to a delivery of said second signal to said patient's body.

Electrosurgical treatment in conjunction with monitoring

An electrosurgical apparatus having improved placement accuracy is provided. The electrosurgical apparatus comprises an elongate shaft having a proximal end, a distal end and at least one lumen therethrough, a stylet positioned within a lumen, a conductive tip at the distal end for delivery of energy to the tissue, an electrical coupling at or near the proximal end for flexibly coupling a power source control unit to supply energy to the conductive tip, a fluid delivery connection interface flexibly coupled at or near the proximal end for coupling a fluid delivery mechanism. The apparatus further comprises a temperature sensor. A method of delivering electrical energy to a target treatment area of an animal body is also provided.

Multifunctional electrosurgical apparatus

A medical probe assembly, system, and methods for the use thereof to treat tissue are described. The system optionally comprises an energy source, two internally-cooled probe assemblies, and one or more cooling devices to provide cooling to at least one of the probe assemblies. The probe assemblies may be configured in a bipolar mode, whereby current flows preferentially between the probe assemblies. The probe assemblies and system described herein are particularly useful to deliver radio frequency energy to a patient's body. RF energy delivery may be used for various applications, including the treatment of pain, tumor ablation and cardiac ablation.
