Abstract: Disclosed is a method to remove distortion from a navigation system. The navigation system may be used to perform a procedure on a subject. The procedure may be any appropriate procedure. The navigation system may be used to account for the distortive effects of various conductive objects positioned near the subject on which the procedure is performed.

Abstract: Disclosed is a system for determining a location and configuration of an expandable member. A flexible coil can be provided on a shape changing portion, such as an expandable portion, to measure a signal as the shape changes.

Abstract: An electromagnetic device includes a jig and multiple wires. The jig includes a center member and coil-separating blocks. The coil-separating blocks protrude from the center member and are separated from each other to provide a coil channels. Each of the wires is wrapped on the jig, around the center member, and in one of the coil channels to form one of a multiple coils. Each of the coils is configured to connect to an electromagnetic navigation system and generate respective electromagnetic fields to be emitted relative to a subject.

Abstract: A system and method for a procedure that can be performed on any appropriate subject. Procedures can include assembling any appropriate work piece or installing members into a work piece, such as an airframe, autoframe, etc. Regardless of the subject, tracking a substantially small tracking device in a plurality of degrees of freedom is provided. The tracking device can be positioned on or be formed in an instrument to be tracked.

Abstract: Disclosed is a system for assisting in guiding and performing a procedure on a subject. The subject may be any appropriate subject such as inanimate object and/or an animate object. The guide and system may include various manipulable or movable members and may be registered to selected coordinate systems.

Abstract: Disclosed is a system that includes pressure sensors to assist in monitoring pressure at a selected location. Pressure sensors may be applied to or incorporated into catheters and/or shunts positioned within a patient. A monitoring system may then receive signals from the pressure sensors to monitor pressure at the location over time.

Abstract: Disclosed is a localizer system. The localizer system may be incorporated into a navigation system for tracking a tracking device. Generally, the localizer may include a transmitting coil array and a field shaping assembly.

Abstract: A guide tube is used for guiding an instrument through a hole within tissue of a patient. The guide tube includes a cannula member defining a passage extending therethrough along an axis. The passage is operable to receive the instrument and guide the instrument through the hole within the tissue of the patient. The guide tube also includes an expansion member that is moveably coupled to the cannula member to selectively move radially between a retracted position and an expanded position relative to the axis of the cannula member. The expansion member is at least partially insertable into the hole when the expansion member is in the retracted position. The expansion member is operable to engage with a surface of the hole when the expansion member is in the expanded position.

Abstract: Disclosed herein, a power supply may be recharged with a generally used system. In various embodiments, cleaning systems may be used to affect a generator to cause the generator to charge a power supply. Such charging systems may be used without the need for separate or specialized power charging systems. A charging source or system may, therefore, also charge a power supply without requiring additional steps.

Abstract: A surgical instrument is disclosed having an elongated body portion having a proximal end and a distal end. The body portion is formed from a plastically deformable material such that the body portion can be bent between the proximal and distal ends from a first configuration to a second bent configuration and maintains the bent configuration. A flexible circuit having at least a pair of lead wires disposed around the body portion. The pair of lead wires are configured to conform to the bent configuration of the body portion such that they do not break during bending of the body portion. A tracking device adapted to cooperate with a navigation system to track the distal end of the instrument is coupled to the flexible circuit.
