Surgical access device having a variable tissue approach angle

A surgical device comprising:

• (a) a proximal structure extending along a longitudinal axis, wherein the proximal structure includes:
• (i) a first guide feature defining a first entry port, and
• (ii) a second guide feature opposed from the first guide feature and defining a second entry port, wherein each of the first and second guide features projects transversely away from the longitudinal axis;
• and
• (b) a cannula extending distally from the proximal structure and having a distal end configured to pass through tissue and into a body cavity of a patient, wherein the cannula includes:
• (i) a working channel sized and configured to receive a surgical instrument axially therethrough,
• (ii) a first exit port disposed on a first side of the cannula, and
• (iii) a second exit port disposed on a second side of the cannula,
• wherein the first entry port is configured to cooperate with the second exit port to define a first suture path that enters the surgical device through the first entry port and passes directly across the working channel to the second exit port to exit the surgical device,
• wherein the second entry port is configured to cooperate with the first exit port to define a second suture path that enters the surgical device through the second entry port and passes directly across the working channel to the second exit port to exit the surgical device,
• wherein each of the first suture path and the second suture path is configured to receive suture therethrough.

A surgical device, comprising:

• (a) a proximal structure, wherein the proximal structure includes:
• (i) a first entry port, and
• (ii) a second entry port diametrically opposed from the first entry port;
• and
• (b) an elongate distal structure extending distally from the proximal structure along a longitudinal axis and having a distal end configured to pass through tissue and into a body cavity of a patient, wherein the proximal structure has a larger maximum lateral dimension than the elongate distal structure, wherein the elongate distal structure includes:
• (i) a first exit port arranged on a first side of the elongate distal structure, and
• (ii) a second exit port arranged on a second side of the elongate distal structure,
• wherein the first entry port is configured to cooperate with the second exit port to define a first suture path that enters the surgical device through the first entry port and passes directly to the second exit port to exit the surgical device,
• wherein the second entry port is configured to cooperate with the first exit port to define a second suture path that enters the surgical device through the second entry port and passes directly to the first exit port to exit the surgical device,
• wherein each of the first suture path and the second suture path extends obliquely to the longitudinal axis and is configured to receive suture therethrough.
