BUTTRESS ASSEMBLY APPLICATOR WITH PROXIMAL ALIGNMENT FEATURES FOR A CURVED TIP SURGICAL STAPLER

A buttress applier cartridge assembly includes buttress assemblies and a buttress applier cartridge for use with an end effector of a surgical stapler. The buttress assemblies each include a buttress to support a staple formed therein as well an adhesive for adhering to the end effector. The buttress applier cartridge includes a housing, a platform that extends longitudinally and supports the buttress assemblies, and an opening to accommodate a curved tip of the end effector when clamping the end effector onto the platform to transfer the buttress assemblies to the end effector. A proximal alignment feature of the buttress applier cartridge contacts the end effector to align the end effector with the buttress assemblies prior to attaching the buttress assemblies to the end effector.
