This application is a division of Ser. No. 13/118,033, filed May 27, 2011, now U.S. Pat. No. 9,554,716, which is a continuation-in-part of U.S. patent application Ser. No. 12/323,273, filed Nov. 25, 2008, now U.S. Pat. No. 8,388,541. This application claims the benefit of the following provisional applications either directly or via the parent application: U.S. Provisional Application No. 61/349,771, filed May 28, 2010, U.S. Provisional Application No. 61/095,921, filed Sep. 10, 2008, U.S. Provisional Application No. 61/095,451, filed Sep. 9, 2008, U.S. Provisional Application No. 61/091,233, filed Aug. 22, 2008, U.S. Provisional Application No. 61/054,944, filed Apr. 17, 2008, and U.S. Provisional Application No. 60/990,242, filed Nov. 26, 2007. Each of the aforementioned applications is incorporated herein by reference in its entirety.
FIGS. 13A-13D show further aspects of the fin connector 156. In particular, the fin connector 156 defines a lower barrel portion 160 that is sized to be received in the channel 152A of the connector base 152 (FIG. 14B, 15). A hole 162 surrounded by a centering cone 164 is included on a back end of an upper barrel portion 166. The upper barrel portion 166 is sized to receive the tether connector 132 of the stylet 130 (FIG. 14C, 15) such that a pin contact 170 extending into a channel 172 of the tether connector 132 (FIG. 15) is guided by the centering hole until it seats within the hole 162 of the fin connector 156, thus interconnecting the tether connector with the fin connector. An engagement feature, such as the engagement feature 169 shown in FIGS. 13C and 13D, can be included on the fin connector 156 to engage with a corresponding feature on the tether connector 132 to assist with maintaining a mating between the two components.
FIGS. 27 and 28 depict components of the guidance system 1110 according to another embodiment, wherein an optical-based interaction between the probe 1140 and the needle 1200 is employed to enable tracking and guidance of the needle. In particular, the probe 1140 includes an optical/light source, such as an LED 1280, and a photodetector 1282 positioned on the probe surface. It is appreciated that the light source and detector can be configured to produce and detect light signals of a variety of ranges including visible, infrared, etc.
1. A method of guiding a needle, comprising: preparing the needle for guidance, the needle including a magnetic element producing a magnetic field;
ultrasonically imaging an image area including an internal body portion target using an ultrasound imaging probe, the ultrasound imaging probe including a plurality of magnetic sensors;
generating magnetic field strength data by continuously sensing the magnetic field of the magnetic element via the plurality of magnetic sensors;
determining a position of the needle relative to the magnetic sensors in three spatial dimensions by processing the magnetic field strength data; and
displaying the position of the needle together with an image of the internal body portion target such that an angle of the needle with respect to the internal body portion target is depicted when the needle is outside of the image area.
2. The method according to claim 1, wherein the magnetic element includes a permanent magnet, further comprising attaching the permanent magnet to a proximal portion of the needle.
3. The method according to claim 2, wherein the permanent magnet includes a hole and a shape of the permanent magnet is selected from the group consisting of a square, a pentagon, a triangle, a rectangle, an oval, an octagon, and a pyramid, wherein the attaching comprises inserting a cannula of the needle through the hole.
4. The method according to claim 2, wherein the magnetic element includes a plurality of permanent magnets, the attaching comprising positioning the plurality of permanent magnets in a hub of the needle.
5. The method according to claim 2, wherein the magnetic element includes at least one bar magnet, the attaching comprising disposing the at least one bar magnet orthogonal to a longitudinal axis of a cannula of the needle.
6. The method according to claim 1, further comprising distributing the magnetic sensors in an arcuate fashion within the ultrasound imaging probe.
7. The method according to claim 1, wherein the needle comprises a barcode or an radio frequency identification (RFID) chip, further comprising storing a length of the needle in the barcode or the RFID chip.
8. The method according to claim 1, further comprising determining a length of the needle by the magnetic field strength data.
9. The method according to claim 1, wherein the plurality of magnetic sensors include orthogonal sensor coils.
10. The method according to claim 1, further comprising continuously updating the image area such that the position and an orientation of the needle with respect to the internal body portion target is continuously updated upon simultaneous movements of the probe and the needle.
