Abstract

A monitoring system is disclosed for in vivo monitoring of preselected physiological parameters associated with acute and/or chronic tissue compromise or failure in one or multiple tissue/organ sites in real time. In one method, a body portion of a surgical stapling device is positioned adjacent a first tissue section, an anvil assembly adapted to engage the body portion is positioned adjacent a second tissue section, and a monitoring device is positioned adjacent the first and/or second tissue sections. The monitoring device includes a sensor adapted to measure a preselected physiological parameter and a transmitter for transmitting signal to an extracorporeal receiving unit. The surgical stapling device is fired to mechanically secure the first and second tissue sections with at least one staple and the preselected physiological parameter is monitored via the information transmitted from the monitoring device to the receiving unit.

Claims

1. A method of real time monitoring of an anastomosis, the method comprising:

positioning a body portion of a surgical stapling device including a staple cartridge adjacent a first tissue section;

positioning an anvil assembly including a shaft adapted to engage the body portion of the surgical stapling device adjacent a second tissue section;

implanting at least one staple including a plurality of monitoring devices adjacent the first tissue section or the second tissue section, each monitoring device of the plurality of monitoring devices comprising a sensor adapted to measure a preselected physiological parameter and a transmitter for transmitting signal to an extracorporeal receiving unit;

firing the surgical stapling device to mechanically secure the first and second tissue sections with the at least one staple from the staple cartridge along a staple line; and

monitoring the preselected physiological parameter via information transmitted from one of the monitoring devices of the plurality of monitoring devices to the extracorporeal receiving unit following completion of the anastomosis.

2. The method of claim 1, further comprising placing a buttress incorporating a monitoring device on the shaft of the anvil assembly.

3. The method of claim 2, further comprising affixing the buttress between the first and second tissue sections using the at least one staple from the staple cartridge of the surgical stapling device.

4. The method of claim 3, wherein firing the surgical stapling device includes the at least one staple having a first monitoring device of the plurality of monitoring devices on a crown of the at least one staple and a second monitoring device of the plurality of monitoring devices on a leg of the at least one staple.

5. The method of claim 4 wherein firing the surgical stapling device further includes positioning the first tissue section and the second tissue section between the first and second monitoring devices of the plurality of monitoring devices of the at least one staple.

6. The method of claim 1, wherein monitoring the preselected physiological parameter further includes sending a signal indicating a measurement of the preselected physiological parameter to the extracorporeal receiving unit.

7. The method of claim 1, further comprising wearing the extracorporeal receiving unit on a body of a patient.

8. The method of claim 1, wherein monitoring the preselected physiological parameter further includes introducing an exogenous marker into the first tissue section or the second tissue section.

13. The method of claim 4, wherein monitoring the preselected physiological parameter further includes measuring properties on each side of, and through, the first and second tissue sections.

9. A method of monitoring tissue in real time, the method comprising:

affixing a staple to tissue in a body of a patient during a surgical procedure, the staple including at least one monitoring device on a crown of the staple and at least one monitoring device on a leg of the staple, each monitoring device comprising a sensor adapted to measure a preselected physiological parameter and a transmitter for transmitting signal from the sensor; and

positioning an extracorporeal receiving unit for collecting data from the monitoring device in proximity to the body of the patient following the surgical procedure, the extracorporeal receiving unit including an indicator to alert the patient when a predetermined test criterion of the preselected physiological parameter is met during post-surgical monitoring.

10. The method of claim 9, wherein positioning the extracorporeal receiving unit further includes placing the extracorporeal receiving unit on the body of the patient.

11. The method of claim 9, wherein affixing the staple further includes positioning tissue between the monitoring devices of the staple.

12. The method of claim 11, further comprising measuring properties on each side of, and through, the tissue via information transmitted from the monitoring devices of the staple.
