The first jaw has a generally rectangular nominal perimeter defining a regular perimeter around outer rows of the plurality of staple cavities. At least one of the first and second jaws has extension elements extending beyond the nominal perimeter of that jaw such that each of the extension elements has at least one attachment feature formed thereon. An adjunct material having a shape complementary to a shape of the jaw is configured to releasably mate with the attachment features formed on the jaw, via corresponding adjunct's mating features.

    Abstract: Various embodiments of a frame for attaching an adjunct to an end effector of a surgical device are provided. In one embodiment, the end effector can include upper and lower jaws, and the frame can include features for releasably engaging one or the jaws. The frame can also include retaining features for coupling an adjunct to a tissue-facing surface of the frame, thereby releasably coupling the adjunct material to the jaw of the end effector. In some implementations, the frame can include a plurality of retaining features that are configured to engage the adjunct material to create a tension in the adjunct material, which can further assist with securing the frame to the jaw. In other embodiments, a removable applicator member is provided for retaining at least one adjunct material and for aligning and coupling the adjunct material to a frame.

    Abstract: An adjunct loading system is provided that can include at least one adjunct material configured to be transferred from an adjunct loading member to first and second jaws of an end effector. The loading system can also include a supporting member configured to releasably retain the adjunct material. The loading system can further include an adhesive depot having an adhesive configured to transition from a non-flowable state to a flowable state upon application of heat when the adjunct material is released from the adjunct loading member and transferred to the jaw to retain the adjunct material on the jaw. The adjunct material is released from the adjunct loading member when load is applied thereto. The adhesive depot can be in the form of an adhesive feature formed on a polymer attachment layer or in the form of reservoirs in the supporting member.

    Abstract: Methods for applying one or more adjuncts to tissue are provided. In one embodiment, the method can include positioning an adjunct, e.g., using an adhesive, on one of first and second jaws of an end effector of a surgical stapler. In one embodiment, an attachment mechanism on the adjunct can prevent stretching of at least a portion of the adjunct. In other aspects, the adjunct can be maintained on the at least one jaw in a first state in which the adjunct is at least partially stretched over the at least one jaw, and actuation of the surgical stapler can cause the adjunct to transition from the first state to a second state such that the adjunct in the second state at least partially separates from the at least one jaw.

    Abstract: A hybrid attachment mechanism is provided to attach an adjunct to an end effector jaw of a surgical instrument, such as a surgical stapler. The hybrid attachment mechanism can include at least two attachment mechanisms, each configured to inhibit at least one manner of detachment from the end effector jaw. A first attachment mechanism can be configured to inhibit vertical removal of the adjunct. A second attachment mechanism can be configured to inhibit sliding of the adjunct with respect to the jaw. A third attachment mechanism can be configured to inhibit curling of the adjunct upon itself. Each of the attachment mechanisms can operate in concert with the others, allowing the hybrid attachment mechanism to simultaneously inhibit multiple forms of adjunct detachment. The hybrid attachment mechanism can be further configured to decouple from the end effector jaw, permitting deployment of the adjunct at a treatment site.
