Abstract

A system for intracranial access that includes a support assembly is described. The support assembly has a hub and lobes surrounding a central aperture for introducing a sheathed core that can accommodate an endoscope and/or other devices. Some embodiments include a collar and a ring, each of which can be tightened to secure the sheathed core in place. An accessory device for use during intracranial aspiration procedures is described.

a fitting disposed about said hub;

whereby the column can be slidingly and tiltably engaged with the support assembly via the central aperture and the ball joint.

2. The system according to claim 1, wherein said column is configured for intracranial access to a subject via a burr hole placed in the skull of the subject.

3. The system according to claim 1, wherein said ball joint comprises a bulb, said hub comprises walls surrounding said central aperture, and said walls are configured to engage said bulb.

4. The system according to claim 1, wherein said lobes comprise a broadened segment.

5. The system according to claim 1, wherein said system further comprises a collar, and said ball joint further comprises a neck, wherein said neck engages said column, and said collar engages said neck, and said collar is configured for tightening and loosening engagement.

6. The system according to claim 5, wherein said collar and/or said neck comprise threading for adjustable engagement with one another.

7. The system according to claim 1, wherein said column comprises a port configured to accommodate the introduction of irrigation fluids and/or one or more navigational elements.

8. The system according to claim 1, wherein said hub and said fitting are configured for threaded engagement with one another.

9. The system according to claim 1, wherein at least one of said lobes comprises one or more apertures for accommodating one or more fastening elements.

10. The system according to claim 1, wherein the system further comprises a socket configured for insertion into a burr hole of a subject, said socket also configured for receiving the support accessory therein.

11. The system according to claim 1, wherein said column further comprises a sheath, and said sheath comprises measured visual indicators.

12. The system according to claim 11, wherein said sheath is configured to be separated into at least two pieces.

13. A system for use in performance of intracranial procedures via a burr hole in a skull of a subject, the system comprising:

a column comprising at least one interior lumen;

a ball joint disposed about said column;

a support accessory disposed about said ball joint, said support accessory comprising a central aperture, a hub, and at least three lobes extending radially from said hub;

a fitting disposed about said hub; and

a socket configured to be inserted into a burr hole of a subject, said socket configured to engage a burr hole and to engage said fitting;

whereby the column can be slidingly and tiltably engaged with the support assembly via the central aperture and the ball joint.

14. The system according to claim 13, wherein said ball joint comprises a bulb, said hub comprises walls surrounding said central aperture, and said walls are configured to engage said bulb.

15. The system according to claim 13, wherein said lobes comprise a broadened segment.

16. The system according to claim 13, wherein said system further comprises a collar, and said ball joint further comprises a neck, wherein said neck engages said column, and said collar engages said neck, and said collar is configured for tightening and loosening engagement.

17. The system according to claim 16, wherein said collar and/or said neck comprise threading for adjustable engagement with one another.

18. The system according to claim 13, wherein said column comprises a port configured to accommodate the introduction of irrigation fluids and/or one or more navigational elements.

19. The system according to claim 13, wherein said hub and said fitting are configured for threaded engagement with one another.

20. The system according to claim 13, wherein said column further comprises a sheath, and said sheath comprises measured visual indicators.

21. The system according to claim 20, wherein said sheath is configured to be separated into at least two pieces.

22. The system according to claim 13, wherein said fitting comprises a stem, and said socket is configured to receive said stem in order to engage said fitting.

23. The system according to claim 22, wherein said stem is expandible.

24. A support assembly for supporting an introducer for performing an intracranial medical procedure on a subject, the support assembly comprising:

a ball joint configured to engage an introducer;

a support accessory disposed about said ball joint, said support accessory comprising a central aperture, a hub, and at least three lobes extending radially from said hub; and

a fitting disposed about said hub;

whereby an introducer can be slidingly and tiltably engaged with the support assembly via the central aperture and the ball joint.

25. The assembly according to claim 24, wherein said assembly is configured for intracranial access to a subject via a burr hole placed in the skull of the subject.
