  • Publication number: 20070239282
    Abstract: A system and method for transmitting implant data includes an orthopaedic implant, a wireless receiver, and a processing circuit electrically coupled to the wireless receiver. The orthopaedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.

  • Publication number: 20070163367
    Abstract: A magnetic sensor array includes a first three-dimensional magnetic sensor secured to a substrate in a central location of the substrate. A number of second three-dimensional magnetic sensors are secured to the substrate at a first distance from the first magnetic sensor. Additionally, a number of one-dimensional magnetic sensors are secured to the substrate at a second distance from the first magnetic sensor greater than the first distance. Additional magnetic sensors of any dimension may also be included. The magnetic field sensitivity of the first and second three-dimensional magnetic sensors may be less than the magnetic field sensitivity of the one-dimensional magnetic sensors. The sensing range of the first and second three-dimensional magnetic sensors may be greater than the sensing range of the one-dimensional magnetic sensors. The magnetic sensor array may also include a processing circuit coupled to the magnetic sensors.

    Abstract: An apparatus and method for registering a bone of a patient with a computer assisted surgery system includes a support frame and a number of magnetic sensor arrays movably coupled to the support frame. Each of the magnetic sensor arrays may be pivoted and translated with respect to the frame. In addition, each of the magnetic sensor arrays may include a circuit for sensing a magnetic field generated by a magnetic source coupled to the bone of the patient. Each circuit may include one or more magnetic sensors, a processing circuit, an angle sensor, a distance sensor, and a transmitter. The magnetic sensors and processing circuit cooperate to determine a position of the magnetic source. The angle sensor, distance sensor, and processing circuit cooperate to determine a displacement of the magnetic sensor array from a reference point. The processing circuit controls the transmitter to transmit data indicative of the position of the magnetic source.

  • Publication number: 20070167703
    Abstract: A method for determining a position of a magnetic source includes measuring a magnetic field generated by the magnetic source and determining components of the three-dimensional magnetic flux density of the magnetic field at a plurality of points in space based on such measurement. The method also includes estimating a position of the magnetic source and determining components of a theoretical three-dimensional magnetic flux density at the plurality of points in space based on the estimated position. The position of the magnetic source may then be determined by minimizing the difference between the components of the measured and corresponding theoretical three-dimensional magnetic flux density components.

The system includes a wireless communication module that is electrically coupled to an implant component having a metal surface so that the implant component operates as an antenna in response to the application of a modulated carrier wave being applied to the implant component. The wireless communication module may be coupled to the implant component so that the implant component operates as a monopole or dipole antenna. When the monopole configuration is used, the system further includes a ground plane so that the electromagnetic field emitted by the implant component is reflected and the emitted and reflected fields resemble the emitted field of a dipole antenna for the carrier frequency.

  • Publication number: 20060000284
    Abstract: A system and method for determining the operating state of a curable composition utilizes an acoustic wave or signal transmitted into a container holding the composition. In one embodiment, characteristics of a reflected component of the acoustic signal are measured and correlated to pre-determined values indicative of one or more operating states, or degrees of curing, of the composition. In another embodiment, characteristics of a transmitted component of the acoustic signal are measured and correlated. The characteristics include, for example, the speed of sound through the curable composition or the attenuation of the acoustic signal reflected by or transmitted through the composition.

  • Publication number: 20050010301
    Abstract: A joint endoprosthesis system has first and second prosthetic components. The second prosthetic component has a bearing surface. The interface of the bearing surface and the first prosthetic component defines the joint articulation. A signal source and sensor are affixed on opposite sides of the joint articulation. The signal source generates a first signal that is received by the sensor. The sensor generates a second signal that has a characteristic that varies depending on the distance between the sensor and the signal source. A transmitter transmits a signal. The signal has a characteristic that varies depending on the characteristic of the second signal. This system can be used to measure a dimension of the joint space and to determine whether a dimension of the joint space has changed over time. The system may alternatively use magnets and magnetic sensors.
