Abstract:
1. A tissue acquisition and fixation system, comprising: a tissue acquisition device having a flexible, elongate main body comprising a plurality of links, each link having a central aperture defining a main lumen therethrough the flexible, elongate body, each link further defining a passage cooperating with adjacent passages in adjoining links to define a routing channel, wherein a distal end of the acquisition device includes a first pod member including a vacuum source adapted to acquire tissue from within a hollow body organ, and a second pod member including a vacuum source adapted to acquire tissue from within the hollow body organ, the first and second pod members adapted to separate apart and separate in an offset condition such that the acquired tissue is adjacent and forms and at least one overlap region such that four layers of tissue are positioned in an adjacent configuration; and a tissue fixation device having an articulatable cartridge assembly adapted to be advanced through the main lumen while maintaining a fixed orientation relative to the main lumen and adapted to staple the four layers of tissue positioned by the first and second pod members together while the pod members are in the apart and offset condition.
