Abstract

A system and method for performing a navigation procedure including a surgical tool, an imaging device, and a computing device. The surgical tool is navigated to a target tissue located in a target area to perform a surgical procedure on the target tissue. The imaging device acquires image data of the target area while the surgical tool is being navigated to the target tissue by automatically traversing back and forth along a path relative to the target area and acquiring image data of the target area while traversing the path. The computing device receives the image data acquired by the imaging device and displays the image data such that the surgical tool can be navigated to the target tissue while simultaneously visualizing a position of the surgical tool relative to the target tissue from multiple perspectives relative to the target area.

First claim

What is claimed is:

1 . A system for performing a navigation procedure, the system comprising:
a surgical tool configured to be navigated to a target tissue located in a target area and to perform a surgical procedure on the target tissue; an imaging device configured to acquire image data of the target area while the surgical tool is being navigated to the target tissue, the imaging device including a motor configured to drive the imaging device along an arcuate path relative to the target area; a user interface for a clinician to set one or more parameters of the imaging device, the parameters including at least one of a length of the path or a speed at which the imaging device traverses the path; and a computing device configured to receive the image data acquired by the imaging device and display the image data on the user interface, wherein the surgical tool can be navigated to the target tissue while under visualization of at least a portion of the surgical tool relative to the target tissue from multiple perspectives.

2 . The system for performing a navigation procedure of claim 1 , wherein the surgical tool includes a catheter guide assembly configured to navigate to the target area via a natural orifice, the catheter guide assembly including a handle and an extended working channel extending from the handle and wherein at least one of a biopsy tool, a marker placement tool, a forceps, or an ablation tool is positionable within the extended working channel to access the target tissue.

3 . The system for performing a navigation procedure of claim 1 , wherein the surgical tool includes at least one of an ablation device including a tapered distal portion configured to percutaneously access the target tissue or a biopsy device including a tapered distal portion configured to percutaneously access the target tissue.

4 . The system for performing a navigation procedure of claim 1 , wherein the imaging device is configured to acquire image data which includes a plurality of fluoroscopic images, each fluoroscopic image of the plurality of fluoroscopic images captured at a different point along the path such that each of the plurality of fluoroscopic images includes an image of the surgical tool relative to the target tissue from a different perspective.

5 . The system for performing a navigation procedure of claim 1 , wherein the imaging device is configured to acquire image data which includes a video of the target area, such that each frame of the video includes an image of the surgical tool relative to the target tissue from a different perspective.

6 . The system for performing a navigation procedure of claim 1 , wherein the imaging device is configured to acquire image data which includes a plurality of fluoroscopic images captured along a first portion of the path and a video captured along a second portion of the path, the first portion different from the second portion.

7 . The system for performing a navigation procedure of claim 1 , wherein the imaging device is configured to receive parameters controlling a format of the image data captured.

8 . The system for performing a navigation procedure of claim 1 , further comprising an electromagnetic field generator operably coupled to the computing device and configured to generate an electromagnetic field, the computing device configured to determine a location of the surgical tool based on the electromagnetic field.

9 . A method for performing a navigation procedure comprising:
initiating navigation of a surgical tool to a target tissue located in a target area; acquiring image data of the target area during navigation of the surgical tool to the target tissue by automatically traversing an imaging device back and forth along a path relative to the target area and acquiring the image data of the target area while traversing the path; displaying the acquired image data during navigation of the surgical tool to the target tissue such that a position of the surgical tool relative to the target tissue is displayed from multiple angles relative to the target area; and completing navigation of the surgical tool to the target tissue under visualization of the position of the surgical tool displayed in each of the multiple angles.

10 . The method for performing a navigation procedure of claim 9 , further comprising performing a procedure on the target tissue.

11 . The method for performing a navigation procedure of claim 9 , wherein initiating navigation of the surgical tool includes:
initiating navigation of a catheter guide assembly including an extended working channel through a natural orifice; and inserting at least one of a biopsy tool, a marker placement tool, a forceps, or an ablation tool through the extended working channel.

12 . The method for performing a navigation procedure of claim 9 , wherein initiating navigation of the surgical tool includes percutaneously inserting at least one of an ablation tool or a biopsy tool including a tapered distal portion through tissue to access the target area.

13 . The method for performing a navigation procedure of claim 9 , wherein acquiring image data of the target area during navigation of the surgical tool to the target tissue includes acquiring a plurality of fluoroscopic images, each fluoroscopic image of the plurality of fluoroscopic images captured at a different point along the path such that each of the plurality of fluoroscopic images includes an image of the surgical tool relative to the target tissue from a different perspective.

14 . The method for performing a navigation procedure of claim 9 , wherein acquiring image data of the target area during navigation of the surgical tool to the target tissue includes acquiring a video of the target area, such that each frame of the video includes an image of the surgical tool relative to the target tissue from a different perspective.

15 . The method for performing a navigation procedure of claim 9 , wherein acquiring image data of the target area during navigation of the surgical tool to the target tissue includes:
acquiring a video of the target area along a first portion of the path; and acquiring a plurality of fluoroscopic images along a second portion of the path, the first portion different from the second portion.

16 . The method for performing a navigation procedure of claim 9 , further comprising receiving parameters controlling at least one of a format of the image data captured, a length of the path, or a speed at which the imaging device traverses the path.

17 . The method for performing a navigation procedure of claim 9 , further comprising:
generating an electromagnetic field about the target area; and determining a location of the surgical tool based on the electromagnetic field.

18 . The method for performing a navigation procedure of claim 9 , further comprising determining that navigation of the surgical tool to the target tissue is complete.

19 . The method for performing a navigation procedure of claim 18 , wherein determining that navigation of the surgical tool to the target tissue is complete includes determining that a distance between the surgical tool and the target tissue in each of the multiple angles is below a threshold.

20 . The method for performing a navigation procedure according to claim 9 , wherein displaying the acquired image data during navigation of the surgical tool includes simultaneously displaying the position of the surgical tool relative to the target tissue from multiple
