Abstract

The present invention discloses a medical device comprising a dispenser adapted to dispense a tissue sealant or one or more precursor compounds, the dispenser being operably coupled to a surgical stapler, which in turn is configured to deliver one or more surgical staples or fasteners in an area of bodily tissue approximation surface. Furthermore, the medical device comprises a dispenser adapted to dispense a tissue sealant or one or more precursor compounds thereof, the dispenser being operably coupled to a surgical cutter. Additionally or alternatively the medical; device can include an actuation mechanism, whereby the dispenser dispenses the tissue sealant or one or more precursor compounds at a surgical cutting site or in a proximity thereof.

Claims

1. A medical device, comprising:

a dispenser adapted to dispense a tissue sealant or one or more precursor compounds thereof, said dispenser being operably coupled to at least one surgical cutter; and

an actuation mechanism, whereby said dispenser dispenses said tissue sealant or one or more precursor compounds at a surgical cutting site or in a proximity thereof.

2. The medical device of claim 1, wherein said surgical cutting site has at least one coating containing said tissue sealant or said one or more precursor compounds.

3. The medical device of claim 1, wherein said surgical cutting site is either partially coated or fully coated with said tissue sealant or said one or more precursor compounds.

4. The medical device of claim 1, wherein said surgical cutter is pre-coated with said tissue sealant or said one or more precursor compounds.

5. The medical device of claim 1, wherein said tissue sealant is formed through at least one reaction that includes one or more precursor compounds.

6. The medical device of claim 5, wherein said at least one reaction includes one of a reaction or a reaction with endogenous substrates, interaction with an endogenous clotting cascade of a bloodstream, a photo reaction with either an internal bodily photons or photons external to a bodily tissue or a thermally-driven reaction or a catalytically-activated reaction.

7. The medical device of claim 1, wherein said dispenser is operably configured to dispense microfluidic amounts of said tissue sealant or said one or more precursor compounds.

8. The medical device of claim 1, wherein said dispenser includes one or more micropipettes that dispense said tissue sealant or said one or more precursor compounds.

9. The medical device of claim 1, wherein said dispenser includes one or more micron-sized outlet ports that dispense said tissue sealant or said one or more precursor compounds.

10. The medical device of claim 1, wherein said dispenser includes one or more microchips containing said tissue sealant or said one or more precursor compounds.

11. The medical device of claim 1, wherein said dispenser includes one or more arrays of microchips containing more than one type of said tissue sealant or said one or more precursor compounds.

12. The medical device of claim 1, wherein said at least one cutter is an optical cutter.

13. The medical device of claim 1, wherein said optical cutter is a laser-mediated cutting device.

14. The medical device of claim 1, wherein said at least one cutter is a manually operable cutter.

15. The medical device of claim 1, wherein said at least one cutter is a programmable cutter.

16. The medical device of claim 1, wherein said at least one cutter is a remotely-operable cutter.

17. The medical device of claim 1, wherein said at least one cutter is a hydraulic cutter.

18. The medical device of claim 1, wherein said at least one cutter is a rotary cutter.

19. The medical device of claim 1 wherein said at least one cutter is a guillotine.

20. The medical device of claim 1, wherein said at least one cutter is a trimmer.

21. The medical device of claim 1, wherein said at least one cutter is an electric cutter.

22. The medical device of claim 1, wherein said at least one cutter includes a clamp-and-cut device.

23. The medical device of claim 1, wherein said at least one cutter includes a shape-cutting device or a shaper or a shaver.

24. The medical device of claim 1, wherein said at least one cutter is an electro-thermal cutter.

25. The medical device of claim 1, wherein said at least one cutter includes one of a blade, a knife, a wire or an edge.
