Redefining Pneumoperitoneum
We’ve re-engineered the familiar to solve the most critical challenge of laparoscopic entry.
VeressPLUS
Lightining fast
A 160 millisecond response in perfect harmony with your hands.The patented ADM Mechanism activates instantly the moment the needle tip enters the peritoneal space, minimising unintended overshooting and its associated risks.
Extraordinary performance
95% vs 5%
In Preclinical studies Participants achieved the optimal insertion depth (10 mm) 95% of the time, a dramatic leap from the 5% achieved by existing Veress needles.

The Science of Precision
Safe abdominal entry is a cornerstone of minimally invasive surgery, yet it remains a step with inherent risks. Conversations with surgeons worldwide have highlighted the need for a more precise language to describe needle advancement. Specifically, two concepts are critical: Optimal Insertion Depth and Overshooting.
Optimal Insertion Depth (OID):
This is the point at which the Veress needle tip enters the peritoneal cavity and allows effective insufflation. OID should not be misconstrued as a “safe depth,” but rather understood as the minimum and necessary depth required to establish pneumoperitoneum. Beyond this depth, no further advancement is required, any additional penetration only increases risk without clinical benefit. Importantly, OID helps reduce excessive penetration but does not eliminate the intrinsic hazards of entry.
A structured survey of 365 surgeons within the European Association for Endoscopic Surgery (EAES) identified 10 mm as the reference OID.
Overshooting:
Overshooting occurs when the Veress needle advances beyond the Optimal Insertion Depth after peritoneal entry. This unintended motion confers no advantage and instead raises the risk of visceral or vascular injury.
Accelerated proficiency
VeressPLUS
Seamless adoption
Preclinical evaluations show that, VeressPLUS requires virtually no learning curve. From the very first use, surgeons can achieve safe and reproducible insertion depths, enabling consistent performance every time.
VeressPLUS
Designed for a good start
Engineered to minimize overshooting and its associated complications, the VeressPLUS provides the peace of mind you need to focus on your patient.
