Abstract

A surgical system and cassette, the cassette having an identification method that is specific to the cassette. Suitable methods include bar coding or Radio Frequency Identification (“RFID”). Cassette information that may be encoded include features such as lot number and performance characteristics, such as pressure sensor calibration data, flow and pressure data and any other performance characteristics of the cassette captured during testing of the cassette at manufacture.

Claims

1. A surgical cassette, comprising:

a) a housing;

b) a pressure sensor on the exterior of the housing; and

c) a means for identifying performance characteristics specific to the cassette.

2. The cassette of claim 1 wherein the identification means comprises a bar code.

3. The cassette of claim 1 wherein the identification means comprises an RFID chip.

4. The cassette of claim 1 wherein the identification means comprises an optical means located on the pressure sensor.

5. A surgical cassette, comprising:

a) a housing;

b) a pressure sensor on the exterior of the housing; and

c) an optical means for identifying performance characteristics specific to the cassette.

6. The cassette of claim 5 wherein the identification means comprises a bar code.

7. The cassette of claim 5 wherein the identification means is located on the pressure sensor.

8. A surgical system, comprising:

a) a surgical console having a cassette receiving portion, the cassette receiving portion having an optical reader;

b) a cassette sized and shaped to be received in the cassette receiving portion of the surgical console; and

c) an optical means, located on the cassette, for identifying performance characteristics specific to the cassette, the identification means being located on the cassette so that the identifying means can be read by the reader when the cassette is received in the cassette receiving portion of the surgical console.

9. The system of claim 8 wherein the identification means comprises a bar code.

10. The system of claim 8 wherein the identification means is located on a pressure sensor in the cassette.

11. A surgical system, comprising:

a) a surgical console having a cassette receiving portion, the surgical console containing a detector;

b) a cassette sized and shaped to be received in the cassette receiving portion of the surgical console; and

c) a non-optical means, located in or on the cassette, for identifying performance characteristics specific to the cassette, the identification means being located on the cassette so that information contained within the identification means can be detected by a detector in the surgical console.

12. The cassette of claim 11 wherein the identification means comprises an RFID chip.

13. The cassette of claim 11 wherein the identification means comprises a microcomputer chip.
