Trocar obturator with transverse needle ports

A trocar assembly, comprising:

• (a) a trocar including:
• (i) a housing assembly,
• (ii) a cannula extending distally from the housing assembly, and
• (iii) a working channel extending axially through the housing assembly and the cannula;
• and
• (b) an obturator configured for use with the trocar, the obturator comprising:
• (i) a shaft extending along a central axis,
• (ii) a head releasably coupled to a proximal end of the shaft,
• (iii) a distal tip configured to puncture tissue,
• (iv) a first pair of needle ports configured to direct a suture passer needle through the obturator along a first suture path oriented obliquely relative to the central axis, and
• (v) a second pair of needle ports configured to direct a suture passer needle through the obturator along a second suture path oriented obliquely relative to the central axis,
• wherein the proximal end of the shaft is configured to pass distally through the working channel when the head is removed from the shaft.

A wound closure device, comprising:

• (a) a head;
• (b) a shaft extending distally from the head along a central axis, wherein the head is selectively decouplable from the shaft;
• (c) a plunger slidably arranged within a central lumen of the shaft, wherein the plunger is resiliently biased toward a proximal position;
• (d) a deployable member coupled to the shaft and the plunger, wherein the deployable member is actuatable by the plunger between a retracted position in which the shaft and the deployable member are configured to be inserted into a working channel of a trocar, and a deployed position in which the deployable member projects radially outwardly from the shaft and is configured to abut an adjacent structure to limit axial movement of the wound closure device relative to the adjacent structure, wherein the head is configured to overcome the resilient bias of the plunger to thereby maintain the plunger in a distal position and the deployable member in the retracted position when the head is coupled with the shaft and the plunger, wherein the plunger is configured to assume the proximal position and the deployable member is configured to assume the deployed position when the head is decoupled from the shaft and the plunger;
• (e) a first pair of needle ports configured to guide a suture passer needle along a first suture path extending through the wound closure device obliquely relative to the central axis;
• and
• (f) a second pair of needle ports configured to guide a suture passer needle along a second suture path extending through the wound closure device obliquely relative to the central axis.
