Abstract

An apparatus includes a body, an upright member, a frame, and a plurality of field generating elements. The body is configured to be positioned between a patient's back and a backrest of a chair. The upright member extends upwardly from the body. The frame has a curved configuration configured to partially surround a patient's head. The field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame.

First claim

1 .- 16 . (canceled)

17 . A method comprising:
(a) positioning a body of a support assembly on a backrest of a chair, above a bottom support of the chair, wherein the support assembly further includes:
(i) an upright member extending upwardly from the body, a frame mounted to the upright member, wherein the frame has a curved configuration configured to partially surround a patient's head, and
(ii) a plurality of field generating elements supported by the frame, wherein the field generating elements are configured to generate an electromagnetic field around a patient's head partially surrounded by the frame; and
(b) securing the body of the support assembly to the backrest of the chair.

18 . The method of claim 17 , wherein the act of securing comprises securing straps to the backrest of the chair to thereby secure the body of the support assembly to the backrest of the chair.

19 . The method of claim 17 , further comprising:
(a) positioning a patient in the chair such that the patient's back engages the body and such that the frame partially surrounds the patient's head; and (b) activating the field generating elements to generate an electromagnetic field around the patient's head.

20 . The method of claim 19 , further comprising:
(a) viewing a navigation screen displaying positioning of a medical instrument in the patient's head, wherein the positioning display is based on data generated using the electromagnetic field; and (b) performing an operation with the medical instrument in the patient's head.

21 . The method of claim 20 , further comprising removing the body from the backrest of the chair after performing the operation.

22 . The method of claim 17 , wherein the upright member defines a longitudinal axis, the method further comprising moving the frame along the longitudinal axis of the upright member.

23 . The method of claim 17 , wherein the upright member defines a longitudinal axis, the method further comprising moving the frame along a dimension that is transverse to the longitudinal axis of the upright member.

24 . The method of claim 23 , wherein the act of moving comprises moving the frame at least one of fore or aft relative to the upright member.

25 . The method of claim 24 , wherein the act of moving comprises moving the frame at least one of fore or aft relative to the upright member along a range of motion including an aft-most position where a rear surface of the frame is approximately 15 cm from a front surface of the backrest.

26 . The method of claim 24 , wherein the act of moving comprises moving the frame at least one of fore or aft relative to the upright member along a range of motion including a fore-most position where a rear surface of the frame is approximately 25 cm from a front surface of the backrest.

27 . The method of claim 17 , further comprising positioning a patient in the chair such that the body is between a back of the patient and the backrest of the chair to seat the patient in an upright position.

28 . The method of claim 17 , wherein the body generally defines an upright plane, wherein the upright member defines an upward sliding direction generally parallel to the upright plane, the method further comprising adjustably sliding the frame in the upward sliding direction.

29 . The method of claim 17 , wherein the body has a wedge shape and includes a front surface and a rear surface, wherein the act of positioning comprises abutting the rear surface of the body against a front surface of the backrest such that the rear surface of the body and the front surface of the backrest are oriented at a first angle relative to the bottom support of the chair and such that the front surface of the body is oriented at a second angle relative to the bottom support of the chair.

30 . The method of claim 29 , wherein the wedge shape has an upper portion and a lower portion, wherein the upper portion has a thickness greater than a thickness of the lower portion, wherein the first angle is greater than the second angle when the rear surface of the body is abutted against the front surface of the backrest.

31 . The method of claim 17 , further comprising selectively locking a vertical position of the frame relative to the upright member.

32 . The method of claim 17 , further comprising selectively locking a lateral position of the frame relative to the upright member.

33 . The method of claim 17 , further comprising exposing at least one of the plurality of field generating elements relative to the body.

34 . A method of using a support assembly, wherein the support assembly includes:
(i) a body, (ii) an upright member extending upwardly from the body, (iii) a frame mounted to the upright member, and (iv) a plurality of field generating elements supported by the frame; the method comprising: (a) positioning the body on a backrest of a chair; (b) removably securing the body to the backrest of the chair; and (c) positioning a patient in the chair such that the body is between a back of the patient and the backrest of the chair to seat the patient in an upright position and such that the frame partially surrounds the patient's head.

35 . The method of claim 34 , wherein the body generally defines an upright plane, wherein the upright member defines an upward sliding direction generally parallel to the upright plane, the method further comprising adjustably sliding the frame in the upward sliding direction.

36 . A method of using a support assembly, wherein the support assembly includes:
(i) a body, wherein the body generally defines an upright plane, (ii) an upright member extending upwardly from the body and defining an upward sliding direction generally parallel to the upright plane, (iii) a frame mounted to the upright member, wherein the frame is configured to be positioned adjacent to a patient's head, and (iv) a plurality of field generating elements supported by the frame, wherein the field generating elements are configured to generate an electromagnetic field around a patient's head adjacent to the frame; the method comprising: (a) positioning the body on a backrest of a chair, above a bottom support of the chair; (b) securing the body to the backrest of the chair; (c) activating the field generating elements to generate an electromagnetic field around the patient's head; and (d) viewing a navigation screen displaying positioning of a medical instrument in the patient's head, wherein the positioning display is based on data generated using the electromagnetic field.
