SHIFTING THE PARADIGM
IN HOW SURGEONS FINISH THEIR PROCEDURES

Over 127 peer reviewed studies show significant benefits from abdominal wall blocks.

  • 67% reduction in post-op opiate use vs local infiltration 5
  • Over 70% of patients report being pain free at 1 hour after laparoscopic surgery 6
  • Abdominal blocks tripled the time to first rescue analgesia 7
  • Patients were discharged significantly earlier 8
  • Rectus Sheath Blocks can provide sufficient pain control without the need for any other post-op analgesia 1


Why isn’t every surgeon doing an abdominal wall nerve block?


Ultrasound guidance is impractical. It requires extra equipment, adds extra costs and can delay surgery by over 18 minutes. 9

Blind Loss of Resistance techniques such as the “Pop-Pop” are inaccurate and dangerous.
Local anesthesia is delivered to the correct plane only 14-24% of the time, and 18% of injections believed to be in the correct plane were actually intraperitoneal. 10




Pain free laparoscopy is possible with targeted nerve blocks 15



LARGE VARIATION in the distance from skin to the pre-peritoneal nerve plane

The thickness of abdominal wall fat and muscle at the umbilicus varies by over 50mm. 4 Current methods for targeting the posterior rectus sheath are inefficient and dangerous, because they approach the nerves from the anterior wall. The wide variation in fat and muscle thickness make blind injections highly inaccurate.

LITTLE VARIATION in the distance from peritoneum to the pre-peritoneal nerve plane

The distance from the peritoneum to the deep nerve plane varies by only 4mm. 3 When measured from below, the extreme variation due to fat and muscle thickness is eliminated and the nerve plane can be consistently targeted.



M-CLOSE uses a patented reference plane system, which positions the Nerve Block Needle relative to the peritoneum, not the skin surface.





M-CLOSE KIT combines targeted anesthesia delivery with the most advanced port closure device 11



M-CLOSE PROVIDES A GOLD STANDARD CLOSURE 11

  • Adheres to the Jonsson-Israelsson rules of fascial closure
  • Suture bites are symmetrical and 1cm from each side of the defect
  • Knot is above the fascial plane

M-CLOSE IS EASY

  • <30 seconds to place the suture
  • Deploys two needles at once
  • Can place multiple sutures for large defects

M-CLOSE IS SAFE

  • No exposed needles help prevent sharps injuries
  • Shielded needles can help prevent injury to intra-abdominal organs, even without pneumoperitoneum, or direct visualization 13

M-CLOSE KIT SAVES MONEY

  • Costs less than most port closure devices
  • Reduce costs related to post-op port site complications
  • Save O.R. time by closing ports faster and avoiding unnecessary scope exchanges
  • Deliver targeted anesthesia at no extra cost






M-CLOSE KIT is designed for OBESE PATIENTS


Current devices use the skin as a reference, resulting in large suture bites as the abdominal wall gets thicker. These large suture bits increase pain and can loosen over time.
M-Close uses the fascia as a reference to produce suture loops that are always the SAME SIZE, regardless of abdominal wall thickness.

Natural movement, angled views, and the inevitable fascial tenting make symmetry difficult with individual needle punctures. M-Close is the ONLY device that simultaneously deploys two opposing needles, ensuring proper 180 degree placement every time.
