  • Patent number: 10569071
    Abstract: Various exemplary devices and methods are provided for performing surgical procedures. In general, one or more adjuncts can be used in conjunction with surgical instruments. The adjunct(s) can have medicant(s) thereon and/or therein. The medicant(s) can vary depending on the desired effect of the medicant(s) on surrounding tissue. As a non-limiting example, medicant(s) can be provided to influence hemostasis, inflammation, macrophages, and/or fibroblasts. When used in conjunction with a surgical stapler, the adjunct(s) can be disposed between and/or on jaws of the stapler, incorporated into a staple cartridge disposed in the jaws, or otherwise placed in proximity to the staples. When staples are deployed, the adjunct(s) can remain at the treatment site with the staples.

  • Patent number: 10555734
    Abstract: Systems and methods for releasably coupling an adjunct material to an end effector for a surgical instrument are provided. The adjunct can be configured to be releasably retained on a jaw, such as a cartridge or anvil, using a contractible attachment feature configured to be transitioned from an original, non-contracted configuration to a contracted configuration under application of heat. The attachment feature, such as one or more strands of a shrinkable polymer, can be engaged with the adjunct, and contraction of the attachment feature is effective to couple the adjunct with retaining members formed on the jaw. Another type of an adjunct has at least one portion configured to be reversibly stretched using application of a force such that, when the force is removed, the portion transitions from a stretched configuration to a contracted configuration and thereby causes the adjunct to be engaged with retaining members formed on the jaw.
