Abstract

A device comprising a kit and a method for using the kit are disclosed that warn a surgeon that the maximal grafting capacity of a recipient tissue has been reached. The increase in interstitial pressure is measured at the recipient site using any of several pressure sensor devices during the grafting process to alert the surgeon to stop grafting once a critical level has been reached, or a sudden increase in pressure is detected, indicative of a maximum graft size.

Claims

1. A kit for determining an optimal graft for a particular recipient tissue site, said kit including a device for measuring an interstitial tissue pressure at said tissue site and a monitor to display the reading of said measuring device.

2. The kit of claim 1 wherein said measuring device comprises a pressure transducer.

3. The kit of claim 2 wherein said measuring device comprises a hydrostatic pressure transducer for connection with a tube to a needle for insertion into the tissue site.

4. The kit of claim 3 further comprising a leveling device for use in aligning the tissue site with the pressure transducer.

5. The kit of claim 3 wherein said monitor includes an adjustment to zero out for differences in elevation between a needle insertion point and the pressure transducer.

6. The kit of claim 3 further comprising a needle for insertion at said tissue site and a length of tubing to connect the needle to the pressure transducer.

7. A method for determining an optimal graft for a particular recipient tissue site using the kit of claim 1 comprising using the measuring device to measure an interstitial pressure at said site as a graft is introduced thereinto, comparing said measured pressure with a threshold interstitial pressure, and ceasing grafting when the measured interstitial pressure reaches said threshold pressure.

8. The method of claim 7 wherein said kit further comprises a pressure transducer as said measuring device, the method further comprising inserting a needle at said tissue site and connecting said needle to said monitor.

9. The method of claim 8 wherein said kit further comprises a hydrostatic pressure transducer as said pressure transducer, the method further comprising adjusting the monitor for any difference in elevation between the needle insertion point and the hydrostatic pressure transducer.

10. The method of claim 9 wherein adjusting the monitor includes leveling the monitor with the needle insertion point.

11. The method of claim 9 wherein adjusting the monitor includes zeroing out the monitor after it is connected to the needle and situated for use.

12. A method for determining an optimal graft for a particular recipient tissue site using the kit of claim 1 comprising using said measuring device to measure an interstitial pressure at said site as a graft is introduced thereinto, and ceasing grafting when the measured interstitial pressure begins to rapidly increase.

13. The method of claim 12 wherein said kit further comprises a pressure transducer as said measuring device, the method further comprising inserting a needle at said tissue site and connecting said needle to said monitor.

14. The method of claim 13 wherein said kit further comprises a hydrostatic pressure transducer as said pressure transducer, the method further comprising adjusting the monitor for any difference in elevation between the needle insertion point and the hydrostatic pressure transducer.

15. The method of claim 14 wherein adjusting the monitor includes leveling the monitor with the needle insertion point.

16. The method of claim 14 wherein adjusting the monitor includes zeroing out the monitor after it is connected to the needle and situated for use.

17. A method for determining an optimal graft for a particular recipient tissue site comprising measuring an interstitial pressure at said site as a graft is introduced thereinto, comparing said measured pressure with a threshold interstitial pressure, and ceasing grafting when the measured interstitial pressure reaches said threshold pressure.

18. The method of claim 17 further comprising inserting a needle at said tissue site and connecting said needle to a monitor to display said measured pressure.

19. The method of claim 18 further comprising using a hydrostatic pressure monitor and adjusting the monitor for any difference in elevation between the needle insertion point and the hydrostatic pressure transducer.

20. The method of claim 19 wherein adjusting the monitor includes leveling the monitor with the needle insertion point.

21. The method of claim 19 wherein adjusting the monitor includes zeroing out the monitor after it is connected to the needle and situated for use.

22. A method for determining an optimal graft for a particular recipient tissue site comprising measuring an interstitial pressure at said site as a graft is introduced thereinto, and ceasing grafting when the measured interstitial pressure begins to rapidly increase.

23. The method of claim 22 further comprising inserting a needle at said tissue site and connecting said needle to a pressure monitor to display said measured pressure.

24. The method of claim 23 further comprising using a hydrostatic pressure transducer and adjusting the monitor for any difference in elevation between the needle insertion point and the hydrostatic pressure transducer.

25. The method of claim 24 wherein adjusting the monitor includes leveling the monitor with the needle insertion point.

26. The method of claim 24 wherein adjusting the monitor includes zeroing out the monitor after it is connected to the needle and situated for use.
