Abstract
A delivery system for an anastomosis connector, comprising: a body including a handle for applying force; a capsule adapted to interlock with said body and for carrying a connector, wherein said force is transferred by said interlocking to deploy said connector; and an extension, adapted to be connected between said body and said capsule, thereby extending a reach of said delivery system.

15. An anastomosis connector comprising:
-
a base plate having a plurality of apertures defined therein; and
a set of pullers adapted to pass through at least some of said apertures during deployment of said connector, wherein said base palate is made spatially sparse enough to allow suturing of an anastomotic connection, using a needle, through the base plate.

16. An anastomosis connector comprising:
-
a plurality of clip segments, each clip defining an engagement volume in which the clip engages tissue;
a plurality of attachment segments interconnecting the clip segments; and
a set of tissue pullers each including at least one tissue engager, wherein, said clips define a plurality of apertures adapted for extending said tissue pullers through the apertures such that retracting the pullers carries engaged tissue into said engagement volume of said clips. - View Dependent Claims (17, 18, 19, 20)
