Abstract

An obturator configured for use with a trocar includes a head and a distally extending shaft configured to be received within a working channel of a trocar. The obturator further includes a distal tip configured to puncture tissue, first and second needle entrance ports each arranged on at least one of the head or the shaft, and first and second needle exit ports arranged on the shaft. The first and second needle entrance ports communicate with the first and second needle exit ports, respectively, to define respective first and second suture paths extending obliquely to the central axis. Each of the first and second suture paths includes at least one sealing element. In some examples, the obturator further includes at least one deployable member coupled to the shaft and configured to project radially outwardly in a deployed position.
