Abstract

A tool assembly for a surgical device includes a first jaw member defining a first tissue contact surface and a second jaw member defining a second tissue contact surface. The first jaw member and the second jaw member are movable in relation to each other between open and closed positions wherein, in the closed position, the first and second tissue contact surfaces are spaced apart from each other and define a tissue gap. A compressible material is secured to a distal end of the first jaw member. The compressible material engages the second jaw member when the first and second jaw members are in the closed position. A surgical device includes the aforementioned tool assembly. A kit includes the compressible material secured on a tool assembly of a surgical device. A method of manufacturing the tool assembly and securing the compressible material is disclosed.

First claim

What is claimed is:

1. A tool assembly for a surgical device, comprising:
a first jaw member defining a first tissue contact surface;
a second jaw member defining a second tissue contact surface, the first jaw member and the second jaw member being movable in relation to each other between open and closed positions, wherein, in the closed position, the first and second tissue contact surfaces are spaced apart from each other and define a tissue gap; and
a compressible material secured to a distal end of the first jaw member,
the compressible material engaging the second jaw member when the first and second jaw members are in the closed position and including a textured surface having raised protrusions that are configured to contact tissue of a subject.

2. The tool assembly according to claim 1 , further comprising an adhesive positioned to secure the compressible material to the distal tip of the tool assembly.

3. The tool assembly according to claim 2 , wherein the adhesive material is selected from the group consisting of cyanoacrylate and pressure sensitive adhesive.

4. The tool assembly according to claim 2 , wherein the adhesive includes a pressure sensitive material configured with a removable backing material to enable adhesion to a surface of the compressible material to secure the compressible material to the distal tip of the tool assembly.

5. The tool assembly according to claim 1 , wherein the second jaw of the tool assembly supports a plurality of staples.

6. The tool assembly according to claim 1 , wherein the second jaw member defines a distal end and the distal ends of first and second jaw members define a wedge-like volume, the compressible material being received in the wedge-like volume.

7. A surgical device comprising:
a handle assembly;
an elongated member extending from the handle assembly; and
a tool assembly supported on a distal end of the elongated member, the tool assembly including:
a first jaw member defining a first tissue contact surface;
a second jaw member defining a second tissue contact surface, the first jaw member and the second jaw member being movable in relation to each other between open and closed positions, wherein, in the closed position, the first and second tissue contact surfaces are spaced apart from each other and define a tissue gap; and
a compressible material secured to a distal end of the first jaw member,
the compressible material engaging the second jaw member when the first and second jaw members are in the closed position and including a textured surface having raised protrusions that are configured to contact tissue of a subject.

8. The surgical device according to claim 7 , further comprising an adhesive positioned to secure the compressible material to the distal tip of the tool assembly.

9. The surgical device according to claim 8 , wherein the adhesive material is selected from the group consisting of cyanoacrylate and pressure sensitive adhesive.

10. The surgical device according to claim 8 , wherein the adhesive includes a pressure sensitive material configured with a removable backing material to enable adhesion to a surface of the compressible material to secure the compressible material to the distal tip of the tool assembly.

11. The surgical device according to claim 7 , wherein the second jaw of the tool assembly supports a plurality of staples.

12. The surgical device according to claim 7 , wherein the surgical device is a surgical stapler.

13. The surgical device according to claim 7 , wherein the second jaw member defines a distal end and the distal ends of first and second jaw members define a wedge-like volume, the compressible material being received in the wedge-like volume.

14. A kit comprising: a tool assembly comprising a first jaw member defining a first tissue contact surface and a second jaw member defining a second tissue contact surface, the first jaw member and the second jaw member being movable in relation to each other between open and closed positions, wherein in the closed position, the first and second tissue contact surfaces are spaced apart from each other and define a tissue gap; a compressible material configured to be secured to a distal end of the first jaw member; and a sterile package supporting the compressible material and the tool assembly; the compressible material engaging the second jaw member when the first and second jaw members are in the closed position and including a textured surface having raised protrusions that are configured to contact tissue of a subject.

15. The kit according to claim 14 , wherein the compressible material supports an adhesive positioned to secure the compressible material to the distal tip of the tool assembly.

16. The kit according to claim 14 , wherein the second jaw member defines a distal end and the distal ends of first and second jaw members define a wedge-like volume, the compressible material being configured to be received in the wedge-like volume.

17. A kit comprising:
a tool assembly comprising a first jaw member and a second jaw member, the first jaw member and the second jaw member being movable in relation to each other between open and closed positions, the first jaw member defining a first tissue contact surface;
a plurality of cartridges, each of the cartridges being adapted to be releasably coupled to the second jaw member and defining a second tissue contact surface; and
a compressible material supported on a distal end of at least one of the plurality of cartridges, wherein in the closed position, the first and second tissue contact surfaces are spaced apart from each other to define a tissue gap and the compressible material is dimensioned to extend across the tissue gap when the at least one cartridge of the plurality of cartridges is coupled to the second jaw member,
wherein the compressible material engages the second jaw member when the first and second jaw members are in the closed position and includes a textured surface having raised protrusions that are configured to contact tissue of a subject.
