Abstract

A device for performing surgical procedures, such as intracardiac procedures or neurosurgical procedures, includes a solid optical window formed of a transparent, compliant material, wherein the solid optical window includes a proximal side and a distal side, wherein a distal face of the solid optical window is configured to approach tissue during a surgical procedure; an imaging system embedded into the solid optical window and positioned to obtain an image through at least a portion of the distal face of the solid optical window; and a tool channel formed through the solid optical window from the proximal side to the distal side of the solid optical window, wherein the tool channel is configured to receive a tool for performing the surgical procedure.

First claim

What is claimed is:

1 . A device for performing surgical procedures, the device comprising:
a solid optical window formed of a transparent, compliant material, wherein the solid optical window comprises a proximal side and a distal side, wherein a distal face of the solid optical window is configured to approach tissue during a surgical procedure; an imaging system embedded into the solid optical window and positioned to obtain an image through at least a portion of the distal face of the solid optical window; and a tool channel formed through the solid optical window from the proximal side to the distal side of the solid optical window, wherein the tool channel is configured to receive a tool for performing the surgical procedure.

2 . The device of claim 1 , wherein the solid optical window is formed from a polymer.

3 . The device of claim 1 , wherein the solid optical window is formed from silicone or silicone rubber.

4 . The device of claim 1 , wherein the distal face of the solid optical window is planar.

5 . The device of claim 1 , wherein a normal to the distal face of the solid optical window is disposed at an angle greater than 0° relative to a longitudinal axis of the solid optical window.

6 . The device of claim 1 , wherein the imaging system comprises one or more cameras or optical fibers.

7 . The device of claim 1 , wherein the imaging system comprises one or more illumination devices.

8 . The device of claim 1 , wherein, when no tool is present in the tool channel, the tool channel is sealed.

9 . The device of claim 1 , wherein, when no tool is present in the tool channel, the tool channel collapses closed.

10 . The device of claim 1 , wherein the tool channel is offset laterally relative to a central axis of the solid optical window.

11 . The device of claim 1 , wherein a longitudinal axis of the tool channel is disposed at an angle between 0° and 90° relative to a longitudinal axis of the solid optical window.

12 . The device of claim 1 , wherein a longitudinal axis of the tool channel is disposed at an angle greater than 0° relative to a longitudinal axis of a distal portion of the imaging system.

13 . The device of claim 1 , further comprising a tube disposed in a proximal portion of the tool channel.

14 . The device of claim 1 , wherein the surgical procedure includes an intracardiac procedure and wherein the distal face of the solid optical window is configured to come into contact with cardiac tissue.

15 . The device of claim 1 , wherein the device is mounted on or integrated into a distal end of a catheter.

16 . The device of claim 1 , wherein the surgical procedure includes a neurosurgical procedure and wherein the distal face of the solid optical window is configured to come into contact with brain tissue.

17 . The device of claim 16 , wherein the device is mounted on or integrated into a distal end of a neuroendoscope.

18 . The device of claim 16 , wherein the device is mounted on or integrated into a lateral surface of a neuroendoscope.

19 . The device of claim 1 , further comprising a flushing channel formed through the solid optical window from the proximal face to the distal face of the solid optical window.

20 . The device of claim 19 , further comprising a tube disposed in a proximal portion of the flushing channel.

21 . The device of claim 19 , wherein, when no liquid is present in the flushing channel, the flushing channel is sealed.

22 . The device of claim 1 , including multiple tool channels formed through the solid optical window.

23 . The device of claim 22 , wherein a longitudinal axis of a first one of the multiple tool channels is disposed at an angle greater than 0° relative to a longitudinal axis of a second one of the multiple tool channels.

24 . The device of claim 22 , wherein the imaging system is positioned to obtain an image of a distal opening of one or more of the multiple tool channels.

25 . The device of claim 22 , wherein the multiple tool channels are positioned such that the tools received by the multiple tool channels meet at a surgical site, and wherein the imaging system is positioned to obtain an image of the tools meeting at the surgical site.

26 . A method for performing a surgical procedure, the method including:
inserting an instrument into a patient, the instrument comprising a solid optical window at a distal end of the instrument, the solid optical window formed of a transparent, compliant material; causing a distal face of the solid optical window to approach tissue of the patient; inserting a tool through a tool channel in the solid optical window, the tool channel formed through the solid optical window from a proximal side to a distal side of the solid optical window; and obtaining an image of the tissue, the tool, or both through at least a portion of the distal face of the solid optical window.

27 . The method of claim 26 , further comprising performing a beating heart intracardiac procedure using the tool.

28 . The method of claim 27 , wherein causing the distal face of the solid optical window to approach tissue of the patient comprises causing the distal face of the solid optical window to come into contact with the tissue.

29 . The method of claim 26 , further comprising performing a neurosurgical procedure using the tool.

30 . The method of claim 26 , wherein obtaining an image comprises obtaining an image of the tissue prior to causing the distal face of the solid optical window to come into contact with the tissue.

31 . The method of claim 26 , further comprising controlling a depth of penetration of the tool into the tissue.

32 . The method of claim 26 , further comprising controlling an angle between the tool and the tissue.

33 . A device for performing surgical procedures, the device comprising:
a hollow optical window formed of a transparent, compliant material, wherein the hollow optical window is configured to be filled with saline, wherein a distal face of the solid optical window is configured to approach tissue during a surgical procedure, the hollow optical window disposed on a distal end of an instrument; an imaging system in the instrument and positioned to obtain an image through at least a portion of the distal face of the hollow optical window; and a tool channel formed through the instrument, wherein the tool channel is configured to receive a tool for performing the surgical procedure, wherein the hollow optical window is configured to allow the tool to pass through the window to perform the surgical procedure.

34 . The device of claim 33 , wherein a position at which the tool passes through the window can be adjusted.

35 . The device of claim 33 , wherein a position of the imaging system in the instrument can be adjusted.

36 . The device of claim 33 , wherein the hollow optical window is configured to expand when filled with saline.
