  • Patent number: 8239001
    Abstract: A surgical navigation system for navigating a region of a patient that may include a non-invasive dynamic reference frame and/or fiducial marker, sensor tipped instruments, and isolator circuits. The dynamic reference frame may be placed on the patient in a precise location for guiding the instruments. The dynamic reference frames may be fixedly placed on the patient. Also the dynamic reference frames may be placed to allow generally natural movements of soft tissue relative to the dynamic reference frames. Also methods are provided to determine positions of the dynamic reference frames. Anatomical landmarks may be determined intra-operatively and without access to the anatomical structure.

  • Publication number: 20110270081
    Abstract: A surgical instrument can include a body, a tracking device, and a handle. The body can include proximal and distal ends, and a flow passage extending therebetween. The body can be formed from a malleable material such that it can be bent between the proximal and distal ends from a first configuration to a second bent configuration and maintain the bent configuration. The tracking device can be positioned adjacent the distal end for tracking a distal tip of the instrument. The handle can be coupled to the proximal end of the body and can include an internal flow passage in fluid communication with the body flow passage. The tracking device can include a pair of lead wires wound around the body to the handle, where the wound wires can conform to the bent configuration of the body such that they do not strain or break during bending of the body.

  • Publication number: 20110261180
    Abstract: A system for performing a medical procedure on a patient is provided. The system can include an imaging head defining a field of view relative to the patient. The imaging head can include at least one transmitter that emits at least one signal in the field of view, and at least one receiver that receives at least one reflected signal from the field of view. The at least one reflected signal received can be based on at least one electrical property of at least one material in the field of view. The system can further include a workstation, which can determine, based on the at least one reflected signal received by the at least one receiver, a location of at least one boundary of the material within the field of view. The system can include a display that displays an image of the location of the at least one boundary.

  • Publication number: 20110238034
    Abstract: A support tool for a supply assembly delivers a functional fluid to an implantable medical device. The supply assembly defines a supply axis. The support tool includes a support member defining an opening. The opening has a support axis, and the opening is configured to receive the supply assembly. The support member includes a three dimensionally contoured nesting surface that conforms to a corresponding three dimensionally contoured surface of the supply assembly. The corresponding surface of the supply assembly nests against the nesting surface to support the supply assembly such that the supply axis remains substantially fixed relative to and aligned with the support axis.

  • Publication number: 20110237935
    Abstract: A system can include an implantable device, an instrument, a display device and a processor. The implantable device can include a port and a localizer for generating a navigation field. The instrument can include a tracking device for sensing the navigation field. The processor can be operably coupled to the tracking and display devices and operable to determine a real-time location of the instrument relative to the port and a trajectory of the instrument relative to an insertion axis of the port. The processor system can be operable to cause the display device to graphically render the instrument as a plurality of two or three-dimensional rings positioned around an axis coincident with the determined trajectory and in spaced relation to each other along the axis. A first ring of the plurality of rings can be positioned at the determined instrument location relative to a graphical representation of the port location.

  • Publication number: 20100234724
    Abstract: An instrument tracking device for cooperating with an instrument during a surgical procedure where the instrument has an elongated body extending along a first longitudinal axis and including a working member at a distal tip includes a body having a distal end and a proximal end. An opening can be formed through the body along a second longitudinal axis. The opening can define a passthrough in the body from the distal end to the proximal end. A first tracking coil can be disposed in the body and can define a first tracking coil axis that is substantially coaxial with the second longitudinal axis of the body. A connection mechanism cooperates between the elongated housing and the body that secures the body to the elongated housing of the instrument upon passing at least a portion of the elongated housing through the passthrough of the body in an assembled position.
