Description

Technical Field

[0001] The present disclosure relates to a user interface and operating platform for using an ablation console and related methods. Background Art

[0002] This section provides background information related to the present disclosure which is not necessarily prior art.

[0003] Ablation devices and systems are used to perform ablative treatments in which a probe is inserted at or near target tissue in a patient's body. The target tissue is typically abnormal tissue, such as a tumor or other growth. Ablation treatments are performed to destroy the target tissue, thereby reducing the likelihood that the target tissue will grow or spread further in the patient's body. One type of ablation is thermal ablation. In thermal ablation, a probe positioned at or near the target tissue raises the temperature of the target tissue (usually in a localized area near the probe) to a temperature at which the target tissue is destroyed.

[0004] Ablation procedures can be performed in various settings. In some cases, it may be desirable to perform an ablation procedure in a setting where an imaging system can be used to collect images to confirm the positioning of the probe in the patient's body. These images can be used to assist in guiding and placing the probe at or near (one or more) target tissues, and reduce the possibility of damage to blood vessels, tissues, organs, or other body structures during the procedure. Various imaging systems can be used in conjunction with ablation procedures, such as computed tomography (CT) systems, magnetic resonance imaging (MRI) systems, ultrasound systems, x-ray systems, etc. Such imaging systems can be large fixed systems that surround one or more parts of the patient during use. It may be challenging to use and / or position the elements of the ablation device and imaging system close to each other. Due to the size, shape, and / or complexity of the ablation system, it may be difficult to move it to a position near the imaging system and / or other therapeutic equipment.

[0005] In addition, existing ablation systems may be large, cumbersome, and difficult to use. Some existing ablation systems include multiple separate elements that operate independently of each other to deliver power to the ablation probe, deliver cooling fluid to the ablation probe, and / or measure operating parameters and / or performance of the ablation probe. The complexity and structure of existing systems may require extensive training, and the performance of ablation therapy may depend largely on the operator's level of experience. Existing systems require operators to follow complex clinical procedures and are often subject to human error, which may result in improper or less than ideal operation. This, in turn, may result in reduced treatment effectiveness or damage to the ablation system. Therefore, there is a need for improved ablation systems and methods that can be easily operated, operated in a manner to obtain optimal treatment results, and can prevent or minimize the ablation system from operating in an undesirable manner.

[0070] Example embodiments will now be described more fully with reference to the accompanying drawings. For the purpose of the following description, it should be understood that the embodiments described below may adopt alternative variations and embodiments. It should also be understood that the specific articles, compositions and / or processes described herein are exemplary and should not be considered as limiting. In the description, relative terms such as "lower", "upper", "horizontal", "vertical", "above", "below", "upward", "downward", "top" and "bottom" and their derivative forms (e.g., "horizontally", "downwardly", "upwardly", etc.) should be interpreted as referring to the orientation shown in the drawings described or discussed later. These relative terms are for ease of description and do not require the device to be constructed or operated in a specific orientation. Terms such as "connection" and "interconnection" regarding attachment, coupling, etc. refer to a relationship in which structures are fixed or attached to each other directly or indirectly through an intervening structure, as well as removable or rigid attachments or relationships, unless otherwise explicitly described.

[0071] Although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not mean sequence or order when used in this article. Therefore, without departing from the teaching of the exemplary embodiment, the first element, component, region, layer or section discussed below may be referred to as the second element, component, region, layer or section.

[0072] In the present disclosure, the singular forms "one", "a piece" and "the" include plural references, and unless the context clearly indicates otherwise, references to a specific numerical value include at least the specific value. When a value is expressed as an approximation, by using the antecedent "about", it should be understood that the specific value forms another embodiment. As used herein, "about X" (where X is a numerical value) preferably refers to ±10% of the stated value, including the endpoints. For example, the phrase "about 8" preferably refers to values ​​of 7.2 to 8.8, including 7.2 and 8.8. If present, all ranges are inclusive and combinable. For example, when reciting a range of "1 to 5", the stated range should be interpreted as including the range "1 to 4", "1 to 3", "1-2", "1-2 and 4-5", "1-3 and 5", "2-5", etc. In addition, when a list of alternatives is provided affirmatively, such a list can be interpreted as meaning that any alternative in the alternatives can be excluded, such as by negative limitations in the claims. For example, when reciting a range of "1 to 5", the recited range may be interpreted as including the case of a negative exclusion of any of 1, 2, 3, 4, or 5; thus, the recitation of "1 to 5" may be interpreted as "1 and 3-5, but not including 2", or simply as "wherein 2 is not included". It is intended that any component, element, attribute, or step that is affirmatively recited herein may be explicitly excluded in a claim, regardless of whether such component, element, attribute, or step is listed as an alternative or whether it is recited separately.

[0073] In various embodiments, the present disclosure provides a microwave ablation device and related methods of use. The microwave ablation device of the present disclosure may include an ablation console, which includes a microwave generator operable to deliver microwave signals to an antenna in an ablation probe. The antenna can deliver microwave energy to a target tissue in a patient's body so as to increase the temperature of the target tissue to a level that destroys the target tissue. The target tissue can be abnormal tissue, such as a tumor or other undesirable growth in the patient's body.

[0074] The ablation device of the present disclosure may include multiple systems that are operated during ablation therapy to raise the temperature of the target tissue to a suitable ablation temperature while cooling the elements of the ablation device to prevent damage to the patient's healthy tissue or the operator of the ablation device. The ablation device may also include one or more measurement elements to monitor the performance of the ablation device during treatment.

[0075] The ablation devices and related methods of use of the present disclosure are improvements over existing devices and methods because the ablation devices of the present disclosure may include an operating platform that may interact and operate multiple systems of the ablation device in a coherent and intuitive manner. Thus, an operator may be able to utilize the ablation devices of the present disclosure with less training and experience than with existing devices. Furthermore, the operating platform may reduce the likelihood of human error and / or damage that may otherwise occur or have occurred to an ablation device utilizing conventional operating methods.

[0076] In some examples of the present disclosure, the ablation device can display one or more user interfaces that can guide an operator through the use and operation of the ablation device. In addition, the operating platform can allow for increased adjustments to the ablation zone that can be delivered by the ablation probe. In addition, the ablation device of the present disclosure can allow an operator to display and use increased information, such as operational information, during an ablation treatment. Further advantages of the ablation device and related methods are described below.

[0077] Figure 1 and Figure 2 An example microwave ablation device 100 is shown in FIG. The microwave ablation device 100 may include a portable base unit 102, a cart 104, and an ablation probe assembly 106. The base unit 102 may be positioned on the cart 104. The base unit 102 may include a microwave generator and a coolant flow generator. In some embodiments, the base unit 102 may have the structure and function described in U.S. Patent Application No. 18 / 477,347, which is entitled CONSOLE ARCHITECTURE FOR MICROWAVE ABLATION UNIT and was filed by Varian Medical Systems, Inc. on the same day as the present application. The application is incorporated herein by reference in its entirety. In various embodiments, the ablation device 100 may be operated to perform ablation therapy by sending a microwave signal to an antenna in the ablation probe 110 via a cable 116. The antenna may deliver microwave energy to a target tissue at or near the ablation probe 110. The microwave energy may cause an elevated temperature at the target tissue to destroy the target tissue.

[0078] During ablation therapy, the ablation device 100 can also use a coolant flow generator to deliver coolant from a coolant cartridge 112 to the probe 110. The coolant cartridge 112 can be inserted into the front of the base unit 102 and engage with a pump to move the coolant from the coolant cartridge 112 to the probe 110 through the cable 116. The movement of the coolant can absorb thermal energy from the cable and / or the probe 110, thereby effectively cooling the cable and / or portions of the probe 110. In some embodiments, the base unit 102 can have a structure and function to provide a coolant flow, as described in U.S. Patent Application No. 18 / 477,328 entitled "PUMP AND CASSETTE SYSTEM FOR USE IN MICROWAVE ABLATION" and U.S. Patent Application No. 18 / 477,374 entitled "MICROWAVE ABLATIONPROBE ASSEMBLY AND CABLE STRUCTURE", each of which was filed on the same day as the present application by Varian Medical Systems, Inc. These applications are incorporated herein by reference in their entirety.

[0079] The base unit 102 and cart 104 can be easily moved in a hospital, treatment center or other environment. The cart 104 can include a support surface, such as a platform 108, which is positioned at an elevated position above the floor to allow access to the functions of the system. The platform 108 can be positioned at a height that is approximately the same as the height of the patient, for example.

[0080] The ablation device 100 may also include a coolant container 118. The coolant container 118 may hold a volume of cooling fluid, such as saline. The coolant container 118 may be fluidly connected to the coolant box 112. The cooling fluid may be moved from the coolant container 118 and moved to the ablation probe assembly 106 using the coolant box 112 and the coolant flow generator in the base unit 102. Thus, during operation, the base unit 102 may control the operation of the microwave generator to deliver a power signal to the probe 110, and control the operation of the coolant flow generator to manage the thermal energy that may be generated during the ablation treatment. In other embodiments, the base unit may not include the coolant box 112. In alternative embodiments, a pump without a box may be used to provide the coolant flow, or a coolant flow system may be provided external to the base unit 102.

[0081] Now go to Figure 3, showing the base unit 102. The base unit 102 may include a display 302. The display 302 may be coupled to the base unit 102 via a hinge 304. The hinge 304 may allow the display 302 to be tilted, rotated, or otherwise adjusted to a desired position for viewing during treatment. The hinge 304 may also allow the display 302 to be laid flat in a position substantially parallel to the top surface of the base unit 102 for storage or transportation. The display 302 may be a suitable flat panel display and may allow a user to interact using a touch screen function. In other examples, the base unit 102 may include suitable ports for attaching other user input devices (such as a keyboard, mouse, trackball, touchpad, etc.).

[0082] As further shown, the base unit 102 may include one or more connector regions. In this example, the base unit 102 includes a first connector region 306 and a second connector region 308. Each of the connector regions 306, 308 may be similarly configured to allow connection of various elements of the ablation probe assembly 106. Each connector region 306, 308 may also include one or more indicators that may indicate to the user the appropriate connections that need to be made in order to operate the ablation device 100 to perform an ablation treatment.

[0083] The first connector area 306 may include a first panel 310, a first box socket 312, and a first probe socket 314. The first panel 310 may include one or more indicators that may provide information to a user. The first panel 310 may be configured to display a display screen that may display text, icons, graphics, numbers, colors, etc. In other examples, the first panel 310 may include a light, a speaker, or other displays that may convey information to a user. The first panel 310 may indicate, for example, numbers, colors, or other guidance information that may indicate to a user the correct connection of a probe, box, or other element to the socket in the first connector area 306.

[0084] The first connector region 306 may also include a first cartridge receptacle 312 that may be sized and configured to receive a coolant cartridge, such as cartridge 112 ( Figure 1). The first cartridge receptacle 312 may also include a light or other indicator that may indicate proper engagement of the cartridge 112 during operation. The first connector region 306 may also include a first probe receptacle 314. The first probe receptacle 314 may be sized and configured to accommodate a probe connector of the probe assembly 106. The first probe receptacle 314 may be configured as a female plug-type connector to electrically and / or operably couple the ablation probe 110 to the base unit 102. The first probe receptacle 314 may also include a light or other indicator that cooperates with the indicators of the first panel 310 and the first cartridge receptacle 312 to indicate to the user that all of these elements are to be used by the common ablation probe assembly 106 during operation.

[0085] The second connector region 308 can be configured similarly to the first connector region 306. The second connector region 308 can include a second panel 320, a second box socket 322, and a second probe socket 324. The second panel 320, the second box socket 322, and the second probe socket 324 can have the same structure and function as the first panel 310, the first box socket 312, and the first probe socket 314, respectively. The indicators of the first panel 310, the first box socket 312, and the first probe socket 314 can, for example, display the same icon, letter, or number, and display the same color. The second panel 320, the second box socket 322, and the second probe socket 324 can each display a different icon, letter, or number and / or display a different color. In this way, during operation of the ablation device 100, a simple indication is provided to the user as to which socket a particular connector should be connected.

[0086] In one example, the first panel 310, the first box socket 312, and the first probe socket 314 can display a first color, and the second panel 320, the second box socket 322, and the second probe socket 324 can display a second color. The probe assembly 106 can also be configured to include a light that is coordinated to display the same color as the probe socket to which it is connected. In some examples, the light can be positioned in the handle of the ablation probe 110. In other examples, the light can be included in the cable 116. In other examples, the light can be included in other locations in the ablation probe assembly 106, such as a connector, wire, pipe, or other location. In some examples, when the ablation probe assembly 106 is connected to the first probe socket 314, the light in the handle of the ablation probe 110 can display the same color as the first probe socket 314. If the ablation probe assembly 106 is connected to the second probe socket 324, the ablation probe 110 can display a second color. In this way, the user can visually see which ablation probe 110 corresponds to which connector during ablation therapy. In existing systems, the user may need to rely on tracing the cable 116 from the probe to the connector. This system eliminates this tedious and difficult task which can lead to human error.

[0087] As further shown, the base unit 102 can also include a first sensor socket 332 and a second sensor socket 334. The first sensor socket 332 and the second sensor socket 334 can each be configured to allow a measuring device (such as a temperature probe) to be electrically or operably coupled to the base unit 102. The temperature probe can provide information about the temperature at or around the target tissue or information about the temperature at other locations where the temperature probe is positioned. The first sensor socket 332 and the second sensor socket can also each include a light or other indicator, which can indicate which socket to use or operate during use of the ablation device 100. The first sensor socket 332 and / or the second sensor socket can be configured as a female plug type connector. In other examples, other types of sockets can be used.

[0088] As shown, base unit 102 includes a pair of connector areas, each of which has the above elements. In other examples, base unit 102 can include other number of connector areas as desired. In such other examples, base unit 102 can include more than two connector areas.

[0089] like Figure 4 As shown, the base unit 102 may include an operating platform 402. The operating platform 402 may include a software platform having various modules that perform various functions of the base unit 102. The operating platform 402 may include, for example, an ablation module 404, a cooling module 406, and a guidance module 408. The ablation module 404 may allow the base unit 102 to perform an ablation therapy that includes energizing the ablation probe 110 to cause microwaves to be emitted from an antenna to heat surrounding tissue. The ablation module 404 may be operated to deliver a power signal having a desired current, voltage, frequency, and / or other characteristics to the ablation probe 110 to create a desired ablation zone in an area near the tip of the ablation probe 110. The ablation module 404 may be coupled to one or more microwave generators in the base unit 102. The ablation module 404 may be coupled, for example, to a first microwave generator 410 and a second microwave generator 420. First microwave generator 410 may be coupled to first ablation probe assembly 432 (e.g., via first probe receptacle 314) to deliver a power signal from first microwave generator 310 to first ablation probe assembly 432. Second microwave generator 420 may be coupled to second ablation probe assembly 434 (e.g., via second probe receptacle 324) to deliver a power signal from second microwave generator 420 to second ablation probe assembly 434.

[0090] The cooling module 406 can be operated to move a cooling fluid through a cooling fluid path to remove heat energy from the ablation probe 110 and / or the cables of the ablation probe assemblies 432, 434. The cooling module 406 can be coupled to one or more coolant flow generators or pumps in the base unit 102. In the example shown, the cooling module 406 can be coupled to the first coolant flow generator 412 and the second coolant flow generator 422. The coolant module 406 can control one or more operating characteristics of the coolant flow generator 422, such as the clamping force of the peristaltic pump, the rotational speed of the peristaltic pump, or other parameters, which in turn can control the flow rate, volume, temperature, and other characteristics of the cooling fluid flowing in the first ablation probe assembly 432 and / or the second ablation probe assembly 434.

[0091] The guidance module 408 may be operable to provide information and / or instructions to allow a user to set up, disconnect, and / or perform various functions of the ablation device 100. The guidance module 408 may provide step-by-step instructions to guide a user through the setup of the ablation device 100 to perform an ablation treatment. The guidance module 408 may interact with the display 302, for example, to show images, pictures, and instructions to the user to guide the user through the steps required to connect various elements of the ablation probe assembly 432, 434 that may be used during an ablation treatment. The guidance module 408 may allow a user to set up the ablation device 100 with less training and / or experience than is required using conventional or existing ablation systems. Although not shown, the guidance module 408 may be coupled to various sensors included in the base unit 102 that may provide information about whether the various elements of the ablation probe assembly 432, 434 are connected to the base unit 102. Upon receiving confirmation of the connection, the guidance module 408 may display information to the user showing the correct connection.

[0092] The base unit 102 may include one or more computing devices that are operable to execute instructions provided in the operating platform 402. The computing device may also include a memory on which the operating platform 402 may be stored. The memory may also record other information and measurements related to the operation of the ablation device 100. The one or more computing devices in the base unit 102 may have the following features and may be used in conjunction with the operating platform 402. Figure 5 In other examples, the computing device may be configured as other devices, hardware, etc., such as by dedicated circuits.

[0093] In other examples, operating platform 402 may be a cloud-based application that may not be locally included in base unit 102, where all or a portion of operating platform 402 may be located remotely from base unit 102, and base unit 102 may communicate via a suitable communications network to access the operating platform and / or one or more of the modules to perform the functionality described herein.

[0094] Reference now Figure 5 , an example computing device 500 is shown. The base unit 102 may include one or more computing devices 500. As shown, the computing device 500 may include one or more processors 502, a working memory 504, one or more input / output devices 506, an instruction memory 508, a transceiver 512, one or more communication ports 514, and a display 516, all of which are operably coupled to one or more data buses 510. The data bus 510 allows communication between various devices. The data bus 510 may include a wired or wireless communication channel.

[0095] The processor 502 may include one or more different processors, each having one or more cores. Each of the different processors may have the same or different structures. The processor 502 may include one or more central processing units (CPUs), one or more graphics processing units (GPUs), application specific integrated circuits (ASICs), digital signal processors (DSPs), etc.

[0096] The processor 502 may be configured to perform a specific function or operation by executing code stored on the instruction memory 508, which embodies the function or operation. For example, the processor 502 may be configured to perform one or more of any functions, steps, methods, or operations disclosed herein, including the functions of operating the platform 402.

[0097] The instruction memory 508 may store instructions that may be accessed (e.g., read) and executed by the processor 502. For example, the instruction memory 508 may be a non-transitory computer-readable storage medium such as a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), flash memory, a removable disk, a CD-ROM, any non-volatile memory, or any other suitable memory.

[0098] The processor 502 may store data to and read data from the working memory 504. For example, the processor 502 may store a set of working instructions to the working memory 504, such as instructions loaded from the instruction memory 508. The processor 502 may also use the working memory 504 to store dynamic data created during operation of the base unit 102. The working memory 504 may be a random access memory (RAM), such as a static random access memory or a dynamic random access memory, or any other suitable memory.

[0099] Input-output device 506 may include any suitable device that allows data input or output. For example, input-output device 506 may include one or more devices of a keyboard, touchpad, mouse, stylus, touch screen, physical buttons, speaker, microphone, or any other suitable input or output device.

[0100] Communication port 514 may include, for example, a serial port, such as a universal asynchronous receiver / transmitter (UART) connection, a universal serial bus (USB) connection, or any other suitable communication port or connection. In some examples, communication port(s) 514 allow programming of executable instructions in instruction memory 508. In some examples, communication port(s) 514 allow transfer (e.g., upload or download) of data, such as ablation measurement or operation data, etc.

[0101] Display 516 can display user interface 518. User interface 518 can enable a user to interact with ablation device 100. For example, user interface 518 can be a user interface that allows an operator to interact, communicate, control, and / or modify different messages, settings, or features that may be presented or otherwise displayed to a user. User interface 518 can include sliders, dialog boxes, or other input fields that allow a user to control, communicate, or modify settings, limitations, or inputs used in ablation therapy. In addition, user interface 518 can include one or more input fields or controls that allow a user to modify or control optional features or customizable aspects of ablation device 100 and / or operating parameters of ablation device 100. In some examples, a user can interact with user interface 518 by engaging input-output device 506. In some examples, display 516 can be a touch screen, where user interface 518 is displayed on the touch screen. In other examples, display 516 can be a computer display that can be interacted with using a mouse or keyboard. Further examples and embodiments of various user interfaces 518 are described below.

[0102] Transceiver 512 allows for communication with a network. In some examples, transceiver 512 is selected based on the type of communication network in which ablation apparatus 100 will operate. Processor(s) 502 are operable to receive data from or send data to a network, such as a wired or wireless network coupling elements of apparatus 100 to each other and to external servers, computing devices, databases, etc.

[0103] The operating platform 402 may perform various functions to enable a user to perform simple, intuitive, and customizable ablation therapy. Figures 6 to 23 Described below and shown are example user interfaces that may be displayed and used to perform various functions of ablation device 100. It should be appreciated that the functions described herein may be performed using other user interfaces and embodiments of operating platform 402.

[0104] Figure 6 An example settings user interface 600 of operating platform 402 is shown. Settings user interface 600 may allow a user to view, change, or input various settings for ablation device 100. Settings user interface 600 may include various categories of settings, such as network settings, data settings, update settings, general settings, etc. User interface 600 may include, for example, sliders, buttons, and data fields to allow a user to adjust settings of ablation device 100.

[0105] Figure 7 An example treatment selection user interface 700 is shown. Treatment selection user interface 700 may allow a user to select a type of treatment to be performed by ablation device 100. Treatment selection user interface 700 may include, for example, one or more buttons 702 that may be used to select the type of procedure or treatment to be performed. In this example, treatment selection user interface 700 includes liver selection button 702a, kidney selection button 702b, lung selection button 702c, and custom selection button 702d. In other examples, treatment selection user interface 700 may include additional buttons or other drop-down menus, etc., to allow a user to select the type of treatment or procedure. Button 702 may correspond to a tissue type in which the target tissue may be located. For example, if a user is performing ablation therapy on a tumor in a patient's lungs, the user may select lung selection button 702c.

[0106] The treatment selection user interface 700 can allow a user to enter a procedure type based on a treatment plan created for a patient. Upon selection using the treatment selection user interface 700, various settings or other parameters of the ablation device 100 can be automatically populated or adjusted to correspond to predetermined treatment parameters for the selected treatment type. Such predetermined treatment parameters can be determined by experimental data, clinical data, other historical data, etc. The predetermined parameters can include information such as the type of probe to be used, the temperature of the ablation cycle, the number of ablation cycles, the power signal to be delivered to the ablation probe, the size of the ablation zone, etc.

[0107] Figure 8 An example needle user interface 800 is shown. The needle user interface 800 can be used to input, change, view, or otherwise operate the ablation probe of the ablation device 100. The ablation probe 110 ( Figure 1 ) may include a needle portion that can be inserted into a patient at or near a target tissue. The needle of the ablation probe can be inserted at or near a target tissue, and a user can use the needle user interface 800 to set various parameters of the ablation device 100 to create a desired ablation zone at the target tissue, thereby destroying the target tissue while minimizing damage to healthy tissue.

[0108] The needle user interface 800 may include a treatment indicator 802. The treatment indicator may display the type of treatment or procedure that has been selected. For example, the user may have selected a liver treatment using the treatment selector user interface 700. The needle user interface 800 may display the selected treatment in the treatment indicator 802. The needle user interface 800 may also include a needle indicator 804. The needle indicator 804 may display the number or type of needles used in the current procedure. In some cases, a single needle may be used to create an ablation zone at the target tissue. In other cases, it may be desirable to use more than one needle. The multiple needles may be independent needles that may each create an ablation zone, such as when there are multiple independent tumors, or when there are body structures near the target tissue that the user desires to be away from the ablation zone. Multiple needles may also be used in a linked configuration, where multiple needles are positioned close to each other to create a single larger ablation zone that would otherwise be impossible using a single needle.

[0109] The needle indicator 804 can display the type of needle and / or the relationship between the multiple needles being used. In the example shown, the needle indicator 806 indicates a single needle icon. The user can select or choose a dual needle linked treatment type or a dual needle independent treatment type using the needle indicator 804. The needle configuration type currently being used can be highlighted, illuminated, or otherwise displayed to the user to indicate the needle configuration currently being used.

[0110] The needle user interface 800 may also include a timer 808. The timer 808 may display the time of the ablation treatment cycle. When the user selects a treatment type, the timer 808 may automatically fill. The timer 808 may also include one or more timer controls that allow the user to adjust the displayed time. Buttons, sliders, input fields, etc. may be used to change the length of time for the ablation cycle. When the ablation cycle begins, the timer 808 may indicate the length of time remaining, the length of time that has elapsed, or other information about the time of the ablation cycle.

[0111] The needle user interface 800 may also include a power indicator 810. The power indicator 810 may display the power to be delivered to the needle's antenna during an ablation cycle. The power may be automatically set initially, and the user may adjust the power using a button, slider, input field, etc. The power may be adjusted up or down as desired to control the ablation zone created during an ablation cycle.

[0112] The needle user interface 800 may also include a needle display 806. The needle display may graphically depict the needle and the ablation zone that will be created using the currently displayed settings. The needle display 806 may display the temperature of the needle at various locations along the length of the needle. The needle of the ablation probe 110 may include temperature sensors positioned at different axial locations along the needle. In this way, the ablation device 100 may monitor the temperature of the needle to indicate the size of the ablation zone created during an ablation cycle.

[0113] The needle user interface 800 may include one or more ablation zone adjusters 820, 822. In the example shown, the needle user interface 800 includes a first adjuster 820 and a second adjuster 822, which may be used to decrease the size of the ablation zone and increase the size of the ablation zone, respectively.

[0114] The needle user interface 800 may also include one or more ablation information selectors 812. The ablation information selectors 812 may be used to select an information data set to be displayed to the user. The ablation information selector 812 may be selected to display further information about temperature, energy, and / or power. As will be further described below, the ablation information selector 812 may be selected to display further user interfaces that may display graphs, data sets, or other information about various aspects of the ablation device 100.

[0115] The needle user interface 800 may also include an ablation start selector 816. The ablation start selector 816 may start an ablation cycle using the current parameters displayed in the needle user interface 800. The ablation start selector 816 may be a button, as shown, which, when selected, causes the ablation device 100 to begin delivering a power signal to the ablation probe to begin emitting microwaves and begin heating tissue at or near the ablation probe.

[0116] The needle user interface 800 may also include a needle lock selector 814. The needle lock selector 814 may allow a user to initiate a needle lock procedure. The needle lock procedure may cause a power signal to be delivered to the needle to cause a rapid burning process to occur at the needle. Such a high power signal may last for less than 10 seconds. In some examples, the needle lock procedure delivers a high power signal for approximately 5 seconds. In other examples, other time periods may be used. The high power signal may be a signal within the following range: the high power signal and the burning may quickly burn the tissue at the needle to lock the needle in place relative to the target tissue. Prior to performing an ablation cycle, it may be desirable to perform a needle lock procedure to minimize or reduce the likelihood of the needle moving during the ablation cycle.

[0117] The needle user interface 800 may also include a tracked ablation selector 818. The tracked ablation selector 818 may allow a user to perform a tracked ablation procedure. The tracked ablation procedure may deliver a power signal to the needle to cause burning, cauterization, or other heating to occur near the needle in the tissue. The tracked ablation procedure may deliver a power signal within a range suitable for this type of procedure.

[0118] In one or more instances during or after an ablation cycle, it may be desirable to track the ablation procedure. In some instances, it may be desirable to track the ablation procedure to minimize or reduce bleeding that may occur after performing an ablation cycle. In other instances, it may be desirable to track the ablation procedure if the needle needs to be moved. Because the needle may come into contact with abnormal tissue, such as cancerous tissue, it is undesirable to move such abnormal tissue to other areas of healthy tissue. If the needle is moved, it may move abnormal cells to a new location. A tracking ablation procedure may be performed to burn or destroy abnormal cells on the needle during needle movement to minimize the movement of such abnormal cells. In other instances, it may be desirable to track the ablation procedure during needle removal after an ablation cycle. During needle removal, a tracking ablation procedure may be performed to destroy any abnormal cells and cauterize the tissue surrounding the needle as the needle is removed from the tissue. Such a procedure may minimize bleeding and result in a faster recovery.

[0119] refer to Fig. 9, another needle user interface 900 is shown. The needle user interface 900 can be similar in many respects to the needle user interface 800 described previously. In this example, the needle display 906 displays the size of the ablation zone that will be created using the settings of the needle user interface 900. The needle display 906 may include various characteristics of the ablation zone. In this example, the needle display 906 includes a length 912 of the ablation zone, which can correspond to the overall size or diameter of the ablation zone. In this example, the needle display 906 also includes a distal stroke 910. The distal stroke 910 can correspond to the distance measured from the needle tip to the outer edge of the ablation zone. In other examples, the needle user interface 900 may include other measurements or indicators of the ablation zone, such as diameter, width, center location, etc.

[0120] The display of the ablation zone size may change dynamically as the parameters of the ablation device 100 are changed in the needle user interface 900. For example, as the cycle time changes, the size of the ablation zone may change dynamically in the needle user interface 900. Similarly, as the power changes, the size of the ablation zone may change dynamically in the needle user interface 900.

[0121] As further shown, the needle user interface 900 may include a geometry selector 914. The geometry selector 914 may allow a user to view, adjust and / or control the geometry of the ablation zone. In the example shown, the geometry selector may include one or more buttons and a diameter selector, and the geometry selector may allow a user to set the size of the ablation zone. For example, a user may desire to increase the length of the ablation zone to correspond to the size of the target tissue. The user may use the geometry selector to increase the ablation length by selecting the "+" button. This may automatically adjust the time, power, or other settings of the ablation device 100 to increase the size of the ablation zone. When the user adjusts the size of the ablation zone in the needle user interface 900, such adjustments may be dynamically displayed in the needle user interface 900. In various examples, the geometry selector 914 may allow the ablation zone to be adjusted to different degrees. In one example, the geometry selector 914 may allow the user to adjust the size of the ablation zone in increments of 0.1 cm. In other examples, other adjustment increments may be used.

[0122] Now go to Fig.10, an example power user interface 1000 is shown. The power user interface 1000 can display the characteristics of the power signal being delivered to the ablation probe during an ablation treatment. The power user interface 1000 can use a graphical display 1008 to show the power, which can depict the delivered power as a function of the time of the ablation cycle. The power user interface 1000 may include a timer 1002, which shows the time remaining in the ablation cycle or other time indication. The power user interface 1000 may also include an indicator 1004, which shows the characteristics of the ablation zone that can be selected using the needle user interface 900, for example. The power user interface 1000 may also include a power setting 1006, which can also be selected or controlled using the needle user interface 900. The power user interface 1000 may also include other information, such as a reflected power and a threshold power corresponding to the power reflected during the ablation cycle. The power user interface 1000 may also allow other information to be superimposed on the graphical display 1008.

[0123] Reference now Fig.11 , an example energy user interface 1100 is shown. The energy user interface 1100 can provide information about the energy delivered during an ablation treatment. The energy user interface 1100 can use a graphical display 1102 to illustrate the energy, which can depict the delivered energy as a function of the time of the ablation cycle. The energy user interface 1100 may include a timer 1104 that shows the time remaining in the ablation cycle or other time indication. The energy user interface 1100 may also include an indicator 1106 that shows, for example, the characteristics of the ablation zone that may have been selected using the needle user interface 900. The energy user interface 1100 may also include a power setting 1108, which may also be selected or controlled using the needle user interface 900. The energy user interface 1100 may also include other information, such as the actual current energy delivered during the ablation cycle and the planned total energy. The energy user interface 100 may also allow other information to be superimposed on the graphical display 1008.

[0124] Reference now Fig.12, an example temperature user interface 1200 is shown. The temperature user interface 1200 can provide information about the temperature during an ablation treatment. The temperature may correspond to the temperature measured at different locations on the ablation probe. The temperature user interface 1200 can use a graphical display 1202 to show the temperature, which can depict the temperature as a function of the ablation cycle time. The temperature user interface 1200 can include a timer 1204, which shows the time remaining in the ablation cycle or other time indication. The temperature user interface 1200 can also include an indicator 1206, which shows, for example, the characteristics of the ablation zone that can be selected using the needle user interface 900. The temperature user interface 1200 can also include a power setting 1208, which can also be selected or controlled using the needle user interface 900. The temperature user interface 1200 can also include other information, such as the current temperature at one or more locations on the ablation probe or in the target tissue. The temperature user interface 1200 can also allow other information to be superimposed on the graphical display 1008. Each temperature at each location at the ablation probe or in the target tissue can be represented by a different graphical line or color.

[0125] Reference now Fig.13 , an example ablation cycle user interface 1300 is shown. The ablation cycle user interface 1300 can provide information about an active ablation cycle being performed. The ablation cycle user interface 1300 can be displayed when a user starts an ablation cycle, and thereafter until the ablation cycle is completed or the user stops the ablation cycle. The ablation cycle user interface 1300 can include a needle display 1302 that displays a graphical representation of the needle and the current temperature at one or more locations on the needle or where a temperature sensor has been positioned. The needle display 1302 can also display a halo or other visual indicator that indicates that the antenna in the needle is energized and that the needle is currently heating the target tissue.

[0126] The ablation cycle user interface 1300 may also include a timer 1304 showing the time remaining in the ablation cycle or other time indication. The ablation cycle user interface 1300 may also include an indicator showing, for example, the characteristics of the ablation zone that has been selected using the needle user interface 900. The ablation cycle user interface 1300 may also include a power setting 1306, which may also be selected or controlled using the needle user interface 900.

[0127] Reference now Fig.14, an example linked needle user interface 1400 is shown. The linked needle user interface 1400 can be similar to the previously described needle user interfaces 800, 900. The linked needle user interface 1400 differs in that it can allow a user to configure and size an ablation zone created by more than one needle. In the example shown, the needle display 1402 includes two needles. In other examples, the linked needle user interface 1400 and the base unit 102 can allow more than two needles to be displayed and operated to create an ablation zone. The display 1402 can allow a user to set the size of the ablation zone and configure the ablation zone using length control, distal stroke control, and / or diameter control. The controls can allow a user to adjust the size and shape of the linked ablation zone.

[0128] The linked needle user interface 1400 may include a first set of indicators 1404, which may correspond to various links, buttons, controls, indicators, etc. that may allow a user to interact with various aspects of the first needle. The linked needle user interface 1400 may also include a second set of indicators 1406, which may correspond to various links, buttons, controls, indicators, etc. that may allow a user to interact with various aspects of the second needle. The linked needle user interface 1400 may also include a needle lock selector 1408 and a track ablation selector 1410. These selectors may operate as previously described to allow a user to perform a needle lock procedure and / or a track ablation procedure, as desired for the first needle and / or the second needle.

[0129] As further shown, the link needle user interface 1400 may include a guide selector 1412. As will be further explained below, the operating platform 402 may include one or more guides to assist a user in performing various actions using the ablation device 100. The guide selector 1412 may initiate a setup wizard or other guide that may assist a user in setting up the ablation probe device 106, including connecting the coolant cartridge 112 and / or the ablation probe 110 to the base unit 102. The guide selector 1412 may allow and / or assist a user in connecting the first needle and / or the second needle to the base unit 102.

[0130] Reference now Fig.15 , an example independent needle user interface 1500 is shown. Independent needle user interface 1500 can allow a user to engage and control multiple needles that can be used for ablation therapy. Compared to linked needle interface 1400, independent needle user interface 1500 allows a user to engage and control multiple needles to cause multiple independent ablation zones to be created during ablation therapy. Needles operated using independent needle user interface 1500 can be independently operated to form multiple separate ablation zones, rather than forming a single ablation zone. In the example shown, independent needle interface 1500 includes two independent needles. In other examples, independent needle interface 1500 can include more than two needles.

[0131] The independent needle interface 1500 may include many of the same elements and functions as the previously described needle user interfaces 800, 900. The independent needle interface 1500 may include a timer and a power indicator, as shown, to control and display the time and power settings for each needle. The independent needle interface 1500 may also include a first needle display 1502 and a second needle display 1504. Each of the needle displays may include a graphical illustration of the needle and temperature measurements of each temperature sensor that may be located on or near each needle. The needle display may allow a user to set the size and configuration of the ablation zone of each needle using length control, distal stroke control, and / or diameter control. Controls may allow a user to adjust the size and shape of each ablation zone independently of one another.

[0132] The independent pin interface 1500 may also include a first set of measurement indicators 1506, which may allow a user to display various measurement user interfaces, such as the previously described power user interface 1000, energy user interface 1100, and temperature user interface 1200. Such interfaces may correspond to the measurement data of the first pin. The independent pin interface 1500 may also include a second set of measurement indicators 1508, which may allow a user to display various measurement user interfaces, such as the previously described power user interface 1000, energy user interface 1100, and temperature user interface 1200. Such interfaces may correspond to the measurement data of the second pin.

[0133] The independent needle interface 1500 may also include multiple groups of controls to allow the functions of each needle to be performed independently of each other. The independent needle interface 1500 may include a first needle lock selector 1510, a first ablation selector 1512, and a first track ablation selector 1514. As previously described, such controls may activate the corresponding function of the first needle. The independent needle interface 1500 may also include a second needle lock selector 1516, a second ablation selector 1518, and a second track ablation selector 1520. As previously described, such controls may activate the corresponding function of the second needle.

[0134] Now go to Fig.16, another example needle user interface 1600 is shown. The needle user interface 1600 may include elements and functions of the previously described user interfaces 800, 900. As shown, the needle user interface 1600 may include a guide selector 1602. The guide selector 1602 may be configured in any suitable manner, such as a button, an input field, etc., to initiate a guide function of the operating platform 402. The operating platform 402 may include a plurality of guide functions to assist a user in performing various functions of the ablation device 100. Some example guide functions include a setup guide, a removal guide, and a troubleshooting guide. The setup guide may initiate one or more user interfaces to guide a user through the steps of properly setting up the ablation device 100 to perform an ablation treatment. The removal guide may initiate one or more user interfaces to guide a user through the steps of properly disassembling the ablation device 100 for storage or subsequent use after an ablation treatment. The troubleshooting guide may initiate one or more user interfaces to guide a user through the steps of determining the cause of a problem, malfunction, or other operational problem with the ablation device 100.

[0135] In the example shown, the guide selector 1602 can initiate the setup guide. After the user selects the guide selector 1602, the guide user interface 1700 can be displayed. The guide user interface 1700 can include a graphical illustration 1702 of the base unit and an illustration 1704 of the ablation probe assembly 106. The guide user interface 1700 can also include instructions 1708 that can describe the steps to be performed by the user. The guide user interface 1700 can also include a channel indicator 1706. The channel indicator 1706 can display the channel or needle that the user is setting. The channel indicator 1706 can display the channel or needle that is being set by the first panel 310 or the second panel 320 ( Figure 3 ) is displayed on the same icon, color, number, letter or other indicator. In this way, the user is clear about which ports or sockets should be used during the setup of the ablation probe assembly 106.

[0136] In this setup step, instruction 1708 informs the user to "open needle package" and "insert box". The ablation probe assembly 106 can be a disposable probe assembly and can be obtained as a sterile assembly enclosed in a sealed package. The various elements of the probe assembly 106 can be included in a package that includes the ablation probe 110, the coolant box 112, the cable 116, and the coolant conduit that can fluidly connect the coolant box 112 to the probe assembly 106.

[0137] like Fig.171706, the channel indicator 1706 may include a graphical icon of the cartridge next to the channel indicator. In this case, the channel indicator shows channel "1", and the icon of the cartridge includes an "x". This "x" indicates that the cartridge has not yet been inserted into the cartridge receptacle 312. The base unit 102 may display a color in the cartridge receptacle 312 via a light to indicate to the user which cartridge receptacle 312 the user should use to insert the cartridge. The color of the light displayed may correspond to the color of the channel indicator 1706, so that simple, easy-to-follow instructions are provided to the user.

[0138] When the user inserts the cartridge 112 into the cartridge receptacle 312, a cartridge insertion user interface 1800 may be displayed ( Fig.18 ). The box insertion user interface 1800 can display a base unit illustration 1804, which shows in a visual or graphical manner that the base unit 102 has sensed that the box 112 has been inserted into the box receptacle 312. The base unit 102 may include a proximity sensor, an electrical sensor, a magnetic sensor, a continuity sensor, etc., which may send a signal to the operating platform 402 to indicate that the user has inserted the box 112 into the box receptacle 312. The base unit 102 may also include a locking mechanism, such as a clip, a pin or other lock, which may engage the box 112 to prevent the box 112 from being removed from the base unit 102. When such a locking mechanism engages the box 112, the box insertion user interface 1800 may display a locking progress bar 1802, which may indicate the progress of the base unit 102 to the user. The locking progress bar 1802 may change and indicate that the box 112 is locked. As further shown, the box insertion user interface 1800 may display the progress of the box insertion step in the channel indicator 1706. As shown, the icon of the box can include a rotating circular graphic element to show that the insertion step is in progress. When the box 112 is fully inserted and locked, the box icon in the channel indicator 1706 can display a check mark other visual indicators to show that the box insertion is complete.

[0139] The operating platform 402 may then move to the next step in the process and display the probe insertion user interface 1900, such as Fig.191900. The probe insertion user interface 1900 may guide the user to install or connect the ablation probe 110 to the base unit 102. The probe insertion user interface 1900 may include an illustration 1904 that visually or graphically illustrates an action to be performed by the user. In this example, the illustration 1904 shows an image of a plug cable 116 to be inserted into the probe receptacle 314. The probe insertion user interface 1900 may also display a channel indicator 1706 and instructions 1902. The instructions 1902 may include text instructions for the action to be performed by the user. In this example, the instructions 1902 indicate to the user "Insert pin electrical connector". The channel indicator 1706 may include a probe connector icon and show the status of the probe connector. In this case, the plug connector icon includes an "x", which shows that the probe connector has not yet been installed in the base unit. In addition to displaying the probe insertion user interface 1900, the operating platform 402 may also cause a light or other visual indicator to be displayed on the base unit 102 to show the first probe receptacle 314 to the user. The operating platform 402 may cause colored lights to be displayed from at or around the first probe receptacle 314. The colors of the lights may be the same as those displayed on the display 302, the first panel 310, the channel indicator 1706, and the cartridge receptacle 312. This makes installation simple and intuitive for the user.

[0140] When the user installs the probe connector into the first probe socket 314, the operating platform 402 can obtain or receive a signal that provides information about the probe assembly 106. The handle of the probe 110 may include a memory device, a chip, or other information source that can provide information to the base unit 102 and / or the operating platform 402. In other examples, the probe information can be located in such a memory device in the probe connector, the cable 116, or other locations. The probe information may include information such as the type of probe, the size of the probe, the manufacturing batch of the probe, the expiration date of the probe assembly, or other identification information. The operating platform can verify whether the correct probe assembly 106 has been connected to the base unit 102. The operating platform 402 can compare such information with information provided by the user, clinical procedures, treatment plans, medical records, etc. This step of verifying the probe information can prevent human error or inadvertent use of a probe that does not meet the requirements of the specific procedure being performed.

[0141] After the probe connector is connected to the probe receptacle 314, the operating platform 402 can display the probe installation user interface 2000. The probe installation user interface 2000 can include a diagram 2002 showing the connection of the probe connector to the probe receptacle 314. The probe installation user interface 2000 can also show status information 2004. The status information 2004 can describe the status of the ablation device 100 to the user. In this example, the status information 2004 informs the user that "needle is detected." In addition, the channel indicator 1706 can show the process that is occurring by displaying a circular arrow graphic on the probe icon. When the operating platform 402 has verified that the correct probe is connected, the channel indicator 1706 can display a check mark or other indicator to show that the step is completed.

[0142] Although not shown, if the operating platform 402 determines that an incorrect or expired probe assembly 106 is connected to the base unit 102, the operating platform 402 can display instructions to remove the probe connector. The user interface 2000 can display information about the probe assembly and instruct the user to take corrective action, such as obtaining and connecting the correct probe assembly 106.

[0143] The operating platform 402 may then display a coolant user interface 2100. The coolant user interface 2100 may display information and instructions to guide the user in connecting the coolant to the base unit 102 and the ablation probe assembly 106. The coolant user interface 2100 may include an illustration 2102 that visually illustrates the components and proper connection of the coolant reservoir 118 to the base unit 102 and the ablation probe assembly 106. The coolant user interface 2100 may also include coolant instructions 2104 that describe the steps to be performed by the user. The coolant user interface 2100 may also display a channel indicator 1706. In this interface, the channel indicator 1706 may include a coolant reservoir icon and may display a status. As shown, the coolant reservoir icon includes an "x" because the operating platform 402 has not detected that the coolant has been connected to the ablation probe assembly 106.

[0144] The coolant user interface 2100 may also include a pump selector 2106. The pump selector 2106 may be a suitable button, actuator, input field, or other selector that may allow a user to cause a coolant flow generator or pump to be activated. Upon selecting the pump selector 2106, the operating platform 402 may cause the first coolant flow generator 412 to be activated, thereby causing coolant to flow from the coolant reservoir 118 to the cartridge 112 and the ablation probe assembly 106.

[0145] Then, the operating platform 402 may display the following Fig. 22The pumping user interface 2200 shown. The pumping user interface 2200 may include an illustration 2202 showing the operation of the ablation device 100. The pumping user interface 2200 may also include status instructions 2204 that provide information to the user about the operation of the ablation device 100. The channel indicator 1706 may also be displayed and show an icon of the coolant reservoir with a graphical status indicator. Here, since the coolant flow path is filled with coolant from the coolant reservoir 118, the channel indicator 1706 shows that a step is in progress by displaying a circle arrow graphic next to the icon of the coolant reservoir. The pumping user interface 2200 may also display a status bar that fills as the step approaches completion. The pumping user interface 2200 may also include a stop selector 2206 that may cause the coolant flow generator or pump to stop its action of flowing coolant.

[0146] The operating platform 402 may then display a completion user interface 2300. The completion user interface 2300 may notify the user that the setup process is complete. The completion user interface 2300 may include an illustration 2302 showing the ablation device 100 in a completed setup configuration. The completion user interface 2300 may also include status information 2304 that may notify the user that the ablation device is ready for use and which channel has been set. The channel indicator 1706 may display a pointer icon and status. In this example, a check mark appears next to the needle icon to indicate that the setup process is complete. After the setup is complete, the user may select a selector 2306 to return to one of the other functions or user interfaces of the operating platform 402. For example, after selecting the selector 2306, if multiple needles were used in the treatment, the operating platform 402 may return to the needle user interface 800, 900 or other interface.

[0147] Now go to Fig.24 , a method 2400 of configuring and / or engaging an ablation device 100 is shown. Although the following description describes the method 2400 being performed by the operating platform 402 and the ablation device 100, it should be understood that the method 2400 may also be performed for other ablation devices.

[0148] The method 2400 may begin at step 2402. At step 2402, the operating platform 402 may instruct the user to connect the coolant cartridge. For example, the operating platform may display the guide user interface 1700. The operating platform may show graphics and diagrams to show where the user should connect the cartridge, and display or indicate the connection location using color-coded lights corresponding to the connection channels.

[0149] In step 2404, the operating platform 402 can determine whether the box is connected. The operating platform 402 can obtain sensor information to determine whether the box 112 is inserted into the box receptacle. Although not shown, the operating platform 402 can also lock the box in the box receptacle after determining that the box 112 is inserted into the box receptacle. If the operating platform 402 determines that the box is not inserted into the receptacle, the method 2400 can return to step 2402 to re-execute steps 2402 and 2404. If the operating platform 402 determines that the box is inserted into the receptacle, the method 2400 can continue to step 2406.

[0150] At step 2406, the operating platform 402 may instruct the user to connect the probe to the base unit 102. The operating platform 402 may display images, graphics, and instructions. For example, the operating platform 402 may display the probe insertion user interface 1900.

[0151] At step 2408, once the probe connector is installed in the probe receptacle, the operating platform 402 can obtain the probe information. As previously described, the ablation probe assembly can include stored information about various aspects of the probe assembly, such as size, type, identification number, manufacturing batch, expiration date, etc. The operating platform 402 can receive this information from the ablation probe assembly 106.

[0152] At step 2410, the operating platform 402 may determine whether the correct probe assembly 106 has been connected to the base unit 102. The operating platform 402 may determine whether the correct probe assembly 106 has been connected by comparing the probe information to the expected or predetermined probe information. The predetermined probe information may have been entered by the user or otherwise obtained from a treatment plan, medical records, database, etc. If the operating platform 402 determines that the correct probe assembly 106 has been connected, the method may continue to step 2414. If the operating platform 402 determines that the incorrect probe assembly 106 has been connected, the method 2400 continues to step 2412.

[0153] At step 2412, the operating platform 402 may instruct the user to disconnect the incorrect probe and correct the connection. The operating platform 402 may display predetermined probe information so that the user can locate and install the correct probe assembly 106. The operating platform 402 may also display and / or instruct the user to perform other actions, such as disconnecting the box, because the probe and the box may be coupled together as part of the probe assembly 106.

[0154] At step 2414, the operating platform 402 may instruct the user to install the coolant. The operating platform 402 may display instructions and diagrams to help the user connect the coolant. For example, the operating platform 402 may display the coolant user interface 2100. The operating platform 402 may instruct the user where and how to connect the coolant reservoir 118, and connect the reservoir 118 to the box, pipe, or probe assembly 106.

[0155] At step 2416, the operating platform 402 may start the pump or flow generator. After the operating platform 402 receives an instruction from the user that the coolant is connected, the operating platform 402 may start the pump. For example, the operating platform 402 may display the pumping user interface 2200. The user interface may display the status of the coolant flow.

[0156] In step 2418, the operating platform 402 can determine whether the coolant is flowing as expected. The operating platform 402 can determine whether the coolant is flowing as expected by comparing the flow characteristics with predetermined flow characteristics. The operating platform 402 can obtain flow information about the flow, volume, temperature, pressure or other information of the coolant and / or other system components from various sensors. In a preferred example, the temperature of the probe can be obtained. This information can be compared with predetermined information obtained by the operating platform from a lookup table, a database, an algorithm, etc. If the operating platform 402 determines that the coolant is flowing as expected, the method 2400 can continue to step 2422. If the operating platform determines that the coolant is not flowing as expected, the method 2400 can move to step 2420.

[0157] At step 2420, the operating platform 402 may notify the user of the status and corrective actions. If the coolant is not flowing properly, there may be a leak, an incorrect connection, a blockage, or other problem. The operating platform 402 may, for example, instruct the user to check the connection and / or correct the coolant connection. The operating platform 402 may detect a leak or defect in the coolant path and require the user to disconnect the probe assembly 106 and restart the process. After 2420, the method 2400 may return to step 2402 to re-execute all steps (or a subset of the steps of the method 2400) required to resolve the identified coolant flow problem.

[0158] At step 2422, the operating platform 402 has determined that the coolant is flowing as desired. In this case, the operating platform 402 can indicate to the user that the ablation device 100 is ready for use. For example, the operating platform 402 can display the completion user interface 2300. When the ablation device 100 is ready for use, the user can perform an ablation treatment in which the probe is powered on to ablate target tissue in the patient.

[0159] Reference now Fig.25, an example method 2500 for creating an ablation zone is shown. The method 2500 may be performed using the operating platform 402 and / or the ablation device 100. However, it should be understood that other platforms and / or other devices may also be used.

[0160] The method 2500 may begin at step 2502. At step 2502, the operating platform may obtain needle information. The needle information may be obtained from a memory chip or other storage device in the ablation probe assembly 106. When the probe assembly 106 is connected to the base unit 102, the operating platform may obtain the probe information from the probe assembly 106. The probe information may include various information about the size, type, and other operating information of the needle of the probe 110.

[0161] The method 2500 may continue to step 2504. At step 2504, the operating platform may display the ablation zone. The operating platform 402 may use the probe information to display characteristics of the ablation zone that may be created using the needle of the probe 110. The characteristics may include the size, shape, distal stroke, diameter, length, and / or width of the ablation zone. For example, the operating platform 402 may display the needle user interface 800 or the needle user interface 900.

[0162] The method 2500 may continue to step 2506. At step 2506, the operating platform 402 may obtain an ablation zone input. The ablation zone input may be information provided by a user to the operating platform 402. The ablation zone input may include a desired size, shape, length, distal stroke, diameter, or other characteristics of a desired ablation zone. The ablation zone may be shown in a display, such as by the needle user interface 800, 900. The size and shape of the ablation zone may be dynamically changed as the user engages with the size and shape inputs and by engaging with time, power, and / or energy selectors in the interface.

[0163] Then, method 2500 may continue to step 2508. At step 2508, operating platform 402 may control the microwave generator to form the ablation zone input at step 2506. Operating platform 402 may adjust or control the microwave generator to control the voltage, current, frequency, or other parameters of the power signal delivered to the antenna in ablation probe 110.

[0164] The method may then proceed to step 2510. At step 2510, the operating platform 402 may determine whether the desired ablation zone is achieved. The operating platform 402 may determine whether the desired ablation zone is achieved by obtaining measurement information from various sensors in the ablation probe 110 or from independent sensors that may be positioned at or near the target tissue. If the desired ablation zone is achieved, the method 2500 may end. If the desired ablation zone is not achieved, the method 2500 may proceed to step 2512.

[0165] At step 2512, operating platform 402 may adjust operating parameters of ablation device 100. Operating platform 402 may adjust the coolant flow in ablation probe assembly 106. Operating platform 402 may also adjust the power signal sent from the microwave generator to probe 110. In other examples, other actions may be performed to achieve the desired ablation zone. After step 2512, method 2500 may return to step 2508 to re-execute steps 2508 and 2510 until the desired ablation is achieved.

[0166] Although not shown, the operating platform 402 can also execute instructions and / or guide the user in a method of removing the ablation device after performing the ablation treatment. The method of removing the ablation device can be the reverse of the method 2400. The example removal method can include displaying various user interfaces with instructions and graphics for removing elements of the probe assembly 106 from the base unit 102.
