  • 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.

  • Publication number: 20080200794
    Abstract: A navigation system generally determines a location of a portion of a first medical instrument relative to a patient. The navigation system generally includes a multi-configuration tracking array that extends from the first medical instrument. A plurality of tracking devices can be positioned on the multi-configuration tracking array. At least one of the tracking devices changes to define at least a first condition and a second condition. A tracking system detects the tracking devices and relates a change between the first condition and the second condition with a change between at least a first instrument configuration and a second instrument configuration.
