What is the purpose of this trial?

This trial explores the performance and safety of the MaxTack™ Motorized Fixation Device for securing mesh to soft tissue during minimally invasive ventral hernia repairs. The researchers aim to assess the device's effectiveness and safety for patients undergoing this type of hernia surgery. They seek volunteers already planning an elective ventral hernia repair with the MaxTack™ device and a specific type of mesh. Ideal participants have not had more than two previous hernia repairs and have no history of allergies to certain surgical materials. As an unphased trial, this study allows patients to contribute to advancements in hernia repair techniques.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the study team or your doctor for guidance.

What prior data suggests that the MaxTack™ Motorized Fixation Device is safe for hernia repair?

Research has shown that the MaxTack™ Motorized Fixation Device has been promising in earlier studies. This device aids in attaching prosthetic material to soft tissue during hernia repair surgeries. Its push-button mechanism facilitates use in less invasive surgeries.

Although detailed study results are not provided, its continued study after market release suggests it has undergone safety testing and is already in use. This indicates the device is likely safe and well-tolerated, with no major safety issues reported so far. However, all medical procedures can carry risks, and results may vary. Prospective study participants should discuss any concerns with their doctor. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The MaxTack™ Motorized Fixation Device is unique because it offers a new, motorized approach to securing prosthetic material during minimally invasive ventral hernia repairs. Traditional methods typically involve manual suturing or stapling, which can be time-consuming and may vary in consistency. Researchers are excited about MaxTack™ because its motorized mechanism promises more uniform fixation, potentially reducing complications and improving recovery times. This innovative device could enhance the precision and efficiency of hernia surgeries, making it a promising alternative to conventional techniques.

What evidence suggests that the MaxTack™ Motorized Fixation Device is effective for ventral hernia repair?

Research has shown that the MaxTack™ Motorized Fixation Device, used in this trial, performs well for hernia repairs. This device employs dissolvable fasteners to attach mesh to soft tissue. Its simple push-button design facilitates use in less invasive surgeries. Early results indicate it securely holds the mesh in place, crucial for successful hernia repair. The device seeks to enhance the attachment process, potentially improving patient outcomes. ^{1 2 3 5 6}

Published Research Related to This Trial

A randomized clinical trial involving 96 patients showed that refurbished external fixation components are as safe and effective as new components, with no significant differences in complications like pin tract infections or loss of fixation.

The refurbishment program resulted in a cost savings of $65,452, which is about 25% of the total cost of using new frames, highlighting its fiscal benefits in a clinical setting.

The MANUFLEX external fixing instrument has been developed for human use and is now being applied successfully in veterinary medicine, particularly for treating bone fractures in dogs, showing promising clinical trial results.

This device is not only patented in Hungary but is also available at a reasonable price for veterinary practitioners, potentially filling a significant need in small animal surgery.

In a study involving 15 pigs, screw-type absorbable and permanent fixation devices for mesh in laparoscopic ventral hernia repair resulted in significantly less tenacious adhesions compared to traditional titanium fixation devices, indicating a potential safety advantage.

The titanium spiral tacks provided the highest pull-off force, suggesting strong fixation, but the absorbable and permanent screw-type devices still offered adequate fixation while reducing adhesion formation, which is important for patient recovery.

The Hifixator, a new unilateral external fixator, demonstrated superior durability in its sliding mechanism, maintaining over 72% of motion at the fracture site even when pins were loosened during dynamic axial loading.

In comparison to other common external fixators like Orthofix and Monotube, the Hifixator's design reduces the risk of binding during ambulation, potentially improving patient outcomes in tibia fracture treatments.

Tack fixation, while providing strong mesh support in laparoscopic hernia repair, has been linked to serious complications such as chronic pain, adhesion formation, and erosion, particularly with permanent metallic tacks like titanium.

Despite the drawbacks and the emergence of absorbable materials, tack fixation remains the most commonly used method for mesh fixation in laparoscopic procedures, as studies have not demonstrated a clear advantage of alternative fixation methods.
