The gastroesophageal collar being submitted for patent intends to primarily prevent the ascension of the fundus above the diaphragmatic plane and also secondarily to improve the function of the Lower esophageal sphincter, thirdly to reduce occurrences of esophageal reflux and thereby hopefully reducing instances of esophageal cancer. It is estimated as high as %20 of the general population has a hiatal hernia experiencing symptoms of acid reflux and making them at higher risk for esophageal cancer. Currently the standard surgical repair of hiatus is fundoplication. The limitations of fundoplication are its high recurrence rate. It often requires a later second procedure to repair / tighten the fundoplication. By using supple bio-inert materials we intend to create a collar that can be left in place, mechanically preventing the ascension of the fundus and improving LES function. We hope to be the first Collar to prevent hiatal hernia and also improve LES function.

An Achilles tendon repair that provides a minimally invasive surgical procedure that requires at least two medical devices comprising: at least one fascial elevator separator and at least one suture passer elevator separator with a paddle guide that assist with repair of Achilles tendons wherein a fascial elevator separator paddle guide that has a U-shaped portion at a distal end provides separation of a Paratenon from an Achilles tendon and also provides a surgical plane along a designated length of the Achilles tendon that eliminates a possibility of damage to either the Sural Nerve or Saphenous Vein. The suture passer elevator separator also provides for precise placement of multiple locking sutures along the medial and lateral free edge if the Achilles tendon which allows even tensioning of the surgical repair.

Tensionable, knotless, self-locking surgical constructs and methods for surgical repairs are disclosed. A tensionable, knotless, self-locking surgical construct includes a flexible coupler (repair suture) and a plurality of shuttle / pull devices loaded onto a fixation device. The fixation device can be a knotless fixation device such as a knotless soft anchor, for example, an all-suture knotless anchor. The knotless surgical construct provides multiple passes of the flexible coupler itself (repair suture itself), to achieve the desired friction and to also create a reverse purchase resistance to loosening. The flexible coupler (repair suture) is passed around tissue two or more times (and subsequently through the cannulation of the anchor sheath two or more times) creating a stuffed friction effect. There is no cinching loop in the final repair.

The next-generation electroadhesive gel, Q800 / G, has been designed for mechanical robustness and degradability, effectively withstanding high burst pressures without compromising adhesive strength and offering significant advancements over current electroadhesive gels. An improved gel exhibited substantial improvements over the original electroadhesion gel (the control gel). The improved gel showed a tensile strength of 115 kPa (17 times greater than the control gels) and elongation at break of 491% (35 times that of the control gels). Adhesion strength of the control gels and the improved gels to anionic gels (sodium acrylate) remained consistent at 20 kPa demonstrating that electroadhesion gels can be strong and degradable, with electroadhesive properties remained. In vitro degradation in PBS at 37°C revealed complete degradation within two weeks, with tunable degradation rates by adjusting PEGDA content. The improved gel demonstrated significant improvement by effectively sealing 4.0 mm intestinal cuts with a burst pressure of 92 mm Hg, outperforming the control gels that failed to repair this size of intestinal injury.

Injuries sealed by a gel patch heal in a predictable manner and faster than those sutured. Times of procedures have been significantly lowered by the use of electroadhesion, suggesting that electroadhesion may be superior to traditional surgical repair methods. Importantly, gels remain well adhered at the injury site in the cecum after several days. For example, mice that underwent electroadhesion survived and showed no adverse effects from the electrical procedure. Surgeries utilizing electroadhesion were quicker than those using sutures, suggesting improved efficiency of the procedure. Wound healing was also more effective in the electroadhesion group, underscoring electroadhesion's potential to enhance the natural wound healing process. Histological analysis showed no significant differences in inflammation severity, indicating that the electroadhesion gel does not trigger significant adverse immune reactions. Additionally, abdominal adhesions were significantly lower in the electroadhesion group.
