Order Info The Benefits of a U-Stitch with the Ease of a T-Fastener
ATLAS™ U-Stitch Demonstration Video
Developed for surgeon ease of use, the ATLAS™ U-Stitch uses exclusive magnetic technology to quickly and safely form a u-stitch within the hollow viscus. After proper placement, the organ is secured to the abdominal wall. Designed with patient comfort and safety in mind, this device was created to decrease the possibility of adverse events during -pexy procedures.
- Increased simplicity of placing a u-stitch.
- Strong securement without metal.
- Consistent and precise suture placement with fixed needle spacing.
- 36% smaller area, 20% lower profile, and > 77% softer bumper versus the leading competitor.1
Hollow Viscus Attachment to the Abdominal Wall
What is the ATLAS™ U-Stitch?
The ATLAS™ U-Stitch builds upon decades of hollow viscus attachment techniques – and improves them for modern surgical practice. This innovative suture delivery system utilizes magnets to form a u-stitch within a hollow viscus to secure the organ to the abdominal wall. After proper placement, only the suture remains, which then can be tied over a soft, silicone bumper – completely metal-free. Following this procedure, an appropriate interventional catheter will be placed according to patient needs.
This device is designed to provide a more broadly applicable and faster alternative to existing manual u-stitches and t-fasteners.
In the abdominal cavity, there are several hollow viscera, including the stomach, large intestine, small intestine, and bladder. Each of these organs has an associated -pexy procedure and resultant applicable interventional catheter that may form part of a treatment plan to address patient needs. In pursuit of placing an interventional catheter, it may be helpful to attach the chosen hollow viscus to the abdominal wall. By approximating the organ to the abdominal wall and securing it, the clinician may then begin to create the needed stoma tract.
In Saini et al. it was found that adhering the viscus to the abdominal wall ahead of the placement of an interventional catheter, compared to not performing the pexy, helped ensure tube patency and prevent possible adverse events such as peritonitis.2

Suture Delivery System with Magnetic Technology
Instead of using a manual lasso or metal anchor, the ATLAS™ U-Stitch utilizes rare-earth magnets to complete the suture loop within the hollow viscus. Once the suture loop is complete and the ATLAS™ U-Stitch is removed, no metal is left behind, eliminating the need for it to pass through the body.

Benefits for Providers + Patients
Designed to Decrease the Possibility of Adverse Events.
As compared to manual u-stitches:
- The ATLAS™ U-Stitch can be used in patients with an abdominal thickness up to 5 cm. Manual u-stitches have limited applicability to differing body types, especially those outside of early childhood.
- The design of the ATLAS™ U-Stitch ensures that the suture bite is consistent across placements, whereas manual u-stitches are often inconsistent.

Device Anatomy
Specially Designed Needles
The ATLAS™ U-Stitch features two parallel introducer needles made of medical-grade stainless steel with cutting-style tips. These tips are designed to reduce the need to nick the skin before insertion of the device. Additionally, these needles feature an anti-coring heel designed to avoid coring of the fascia during insertion.
Exclusive Suture
The suture left after placement is a 3-0 braided permanent suture. This suture is FDA cleared to remain in place for up to 14 days following placement and does not lose strength over the placement period.
Comfortable Bumper
This soft and flexible silicone bumper can be used to separate the suture knot from the top of the skin. Its low-profile design is meant to maximize comfort for the patient.
Safety Aspects
The device has safety features that guard against accidental early deployments and associated risks. These include a needle cover to sheath the needle tips and a device lock to prevent depression of the advancement hub prematurely.
