Claims (18)

  1. A medical tool, comprising: an electromechanical driver; an application element driven by said electromechanical driver and configured to interact with a section of tissue; a sensor assembly capable of sensing and transmitting data corresponding to at least one of a condition of the section of tissue and an interaction between the section of tissue and the application element; and a processor element capable of receiving said data and controlling said electromechanical driver in correspondence with said data.
  2. The medical tool as set forth in claim 1, wherein said sensor said assembly is activated upon, and is capable of, receiving an activation signal transmitted by said processor element.
  3. The medical tool as set forth in claim 1, further comprising an alert element coupled to said processor element and capable of communicating at least one of an aspect of the data received by said processor element and an aspect of the processor element's control of the electromechanical driver.
  4. The medical tool as set forth in claim 1, wherein said sensor assembly comprises a tissue proximity detector.
  5. The medical tool as set forth in claim 1, wherein, said processor element is capable of preventing activation of said electromechanical driver.
  6. The medical tool as set forth in claim 1, wherein the application element includes an anvil and a stapling arrangement configured to be driven by the electromechanical driver.
  7. The medical tool according to claim 6, wherein the electromechanical driver is housed in the processor.
  8. The medical tool according to claim 6, wherein the anvil and stapling arrangement is a circular stapler.
