  • Surgical stapler flexible distal tip
    Patent number: 10835242
    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.
