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.

Claims

1. A system comprising:

a gate having a passageway and a primary coil formed from a number of first coil turns positioned so as to define a first reference plane; and

an orthopaedic implant comprising;

a platform having a bottom surface,

a stem secured to the bottom surface of the platform and extending downwardly therefrom,

a housing coupled to the stem having a chamber defined therein, and

a secondary coil formed from a number of second coil turns in registry with each other, each second coil turn extending in a first direction parallel to the bottom surface of the platform to define a longitudinal axis of the secondary coil, each coil turn of the secondary coil being positioned in a second reference plane extending orthogonal to the longitudinal axis,

wherein the secondary coil is positioned in the chamber of the housing of the orthopaedic implant such that the second reference plane is capable of being oriented substantially parallel with the first reference plane and the longitudinal axis is capable of being oriented substantially orthogonal to the first reference plane when the orthopaedic implant is implanted in a body of a patient and the patient is traveling through the passageway.

2. The system of claim 1, wherein the first reference plane and the second reference plane are capable of being oriented substantially parallel with a sagittal plane of the body of the patient and the longitudinal axis is capable of being oriented substantially orthogonal to the sagittal plane of the body of the patient when the orthopaedic implant is implanted in a body of a patient and the patient is traveling through the passageway.

3. The system of claim 1, wherein:

the orthopaedic implant is configured to transmit implant identification data and implant sensor data in response to a power signal;

the primary coil is configured to inductively couple with the secondary coil of the orthopaedic implant to provide the power signal to the orthopaedic implant; and

the system further comprises;

a wireless receiver configured to receive the implant identification data and the implant sensor data transmitted by the orthopaedic implant;

a processor coupled to the wireless receiver; and

a memory device electrically coupled to the processor, the memory device having stored therein a plurality of instructions, which when executed by the processor, cause the processor to;

receive the implant identification data and the implant sensor data from the wireless receiver;

retrieve patient-related data from a database based on the implant identification data; and

update an electronically-stored patient queue in response to receiving the implant identification data and retrieving the patient-related data.

transmit the implant sensor data to a client machine located in the patient room assigned to the patient.

18. The system of claim 17, wherein the plurality of instructions further cause the processor to:

determine the availability of the patient room based on an electronically-stored patient queue; and

provide an electronic notification if the patient room is available,

determine the availability of the patient room based on the electronically-stored patient queue; and
