Abstract

A biopsy system includes a host and a biopsy driver assembly. The host is configured to execute program instructions associated with an application. The host has a first IrDA interface. The biopsy driver assembly has a controller for executing program instructions and a user interface providing user input to the controller. The biopsy driver assembly has a second IrDA interface. The second IrDA interface is default disabled. The controller of the biopsy driver assembly has sole control in enabling the second IrDA interface to in turn enable an infrared communications link between the first IrDA interface of the host and the second IrDA interface of the biopsy driver assembly.

Claims

1. A biopsy system, comprising:

a host configured to execute program instructions associated with an application, said host having a first IrDA interface; and

a biopsy driver assembly having a controller for executing program instructions and a user interface providing user input to said controller, said biopsy driver assembly having a second IrDA interface, said second IrDA interface being default disabled;

said controller of said biopsy driver assembly having sole control in enabling said second IrDA interface to in turn enable an infrared communications link between said first IrDA interface of said host and said second IrDA interface of said biopsy driver assembly.

2. The biopsy system of claim 1, wherein said application executing on said host provides password protected access to said biopsy driver assembly when said infrared communications link is enabled.

3. A biopsy system, comprising:

a host configured to execute program instructions associated with an application, said host having a host memory;

a biopsy driver assembly having a controller, firmware, a driver memory, and an event log established in said driver memory, said firmware having program instructions which when executed by said controller update said event log to record events related to usage of said biopsy driver assembly; and

said host executing program instructions from said application to retrieve said event log from said biopsy driver assembly over said infrared communications link.

4. The biopsy system of claim of claim 3, wherein said infrared communications link includes a first IrDA interface at said host and a second IrDA interface at said biopsy driver assembly, said biopsy driver assembly having a user interface, said second IrDA interface being as default disabled and is only enabled by a specific command entered at said user interface of said biopsy driver assembly.

5. The biopsy system of claim 3, wherein said event log is one of a plurality of event logs, each of said plurality of event logs storing data associated with a date and time of an occurrence of a respective biopsy event.

6. The biopsy system of claim 5, wherein said respective biopsy event includes an event associated with a tissue sample harvesting operation.

7. The biopsy system of claim 5, wherein said respective biopsy event includes an event associated with a piercing shot operation.

8. The biopsy system of claim 5, wherein each of said plurality of event logs stores an event count associated with said respective biopsy event.

9. The biopsy system of claim 5, said host executing program instructions from said application to analyze said plurality of event logs to determine a pattern of usage of said biopsy driver assembly.

10.
