  • Patent number: 9662041
    Abstract: An area of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of an area or volume can be determined based upon the sensing of the plurality of points without the use of an imaging device. An implantable medical device can then be navigated relative to the mapping data.

  • Patent number: 8983619
    Abstract: A system and method are described for testing communication through a patient during implantation using telemetry coupling electrodes on a delivery catheter. In one example, at least two telemetry coupling electrodes may be placed on or within a delivery catheter to test conductive communication with external body electrodes during implantation. In some instances, the telemetry coupling electrodes of the delivery catheter may approximate the spacing of telemetry electrodes on an IMD. In this manner, testing conductively coupled communication with telemetry coupling electrodes of the catheter may be used to mimic the telemetry electrodes on the IMD and determine a target position and/or orientation of an electrode or electrodes of the IMD for successful conductive communication through the body.

    Abstract: A system for determining a location of an instrument within an anatomy is provided. The system can include a first instrument, which can define at least one lumen. The system can further include a second instrument, which can be received through the at least one lumen. The system can include at least one electrode, which can be coupled to a distal end of the first instrument. The electrode can be responsive to electrical activity to generate at least one signal. The system can include a sensing unit, which can be in contact with the anatomy to sense electrical activity within the anatomy at a location near the instrument. The sensing unit can be in communication with the electrode to receive the signal.
