As circular stapler designs evolve, they provide the means for an incr
easing range of surgical techniques. It appears that the long-term dir
ection of this evolution will coincide with that of minimally invasive
therapy (MIT). The range of techniques available using the current in
struments is scattered throughout the literature. This range is presen
ted as a rationalized collation. Technologists working on the developm
ent of MIT anastomotic equipment will find the core of a design specif
ication for future development prescribed.
