The Clinical Problem

Hernias are a biomechanical failure of force distribution

Hernias develop when the forces acting on the abdominal wall exceed the strength of the surrounding tissues. Repeated internal pressure, uneven muscle tension, and weakened connective tissue can gradually lead to structural failure. 1,2 Previous abdominal surgery may further weaken the abdominal wall, increasing the risk of incisional hernias. 3,4 Conventional repairs often require a tradeoff between high-tension sutures, which are associated with higher recurrence rates, and mesh reinforcement, which can reduce recurrence but may introduce risks such as infection, chronic pain, and reoperation.3,5,6
Effective hernia treatment requires restoring the structural integrity of the abdominal wall while also re-establishing physiologic force distribution across the repaired tissues. 7
What is TAS?

Tissue Approximation System (TAS)

TAS (Tissue Approximation System) is a force-distributing  closure device designed to facilitate controlled approximation of fascial tissue by creating a repair contract that provides tissue apposition and supports restoration of normal anatomic alignment.

Why Choose TAS

TAS is designed for controlled tissue approximation

TAS – Tissue Approximation System is engineered to: 

Distribute tissue forces across the repair construct

to reduce localized stress at individual suture sites during tissue approximation.

Provide procedural flexibility

by supporting tissue approximation across a variety of surgical approaches, including open and minimally invasive techniques, as determined by the surgeon.

Support Sequential Closure

Support gradual or sequential tissue approximation to assist surgeons in managing challenging abdominal wall defects and achieving fascial closure.

Promote more uniform force distribution

across the abdominal wall, which may reduce reliance on high-tension closure techniques and may provide an alternative to mesh reinforcement in selected cases, as determined by the surgeon.

Provide an alternative approach to tissue approximation

that may reduce the need for extensive tissue mobilization associated with certain reconstructive techniques, depending on patient anatomy and surgical judgment.

Offer surgeons an additional option for abdominal wall reconstruction

that may reduce reliance on biologic reinforcement materials in appropriately selected patients.

A New Treatment Modality

Force Modulating Closure Devices For Hernia Repair

TAS sits in a category all its own — distinct from suture and mesh — spreading load across a wider surface and away from the suture-tissue interface.

Localized tension & stress concentration at suture points.
Force distributed over a larger surface area.
Single point mesh + suture fixation that increases foreign body footprint.

The need for mesh in hernia repair has often been a response to the inability to achieve adequate primary fascial closure from suture alone. 3

TAS is designed to distribute tissue forces across a broader surface area during abdominal wall approximation, with the goal of reducing localized stress at individual fixation points.
 
TAS is designed to provide controlled, gradual approximation of tissue edges while distributing forces across the abdominal wall. This engineering approach is intended to support tissue approximation without concentrating loads at individual suture sites.
