Knotless Methods and Constructs for Tissue Repairs and Reconstructions

Smart overview of the Invention

This patent application details innovative surgical constructs and methods for tissue reinforcement and repair. The constructs utilize a reinforcement material equipped with a self-locking mechanism, allowing for knotless, tensionable, and self-cinching tissue repairs. These constructs are designed to enhance surgical efficiency by reducing the number of suture passes required and providing uniform soft tissue compression.

Components and Mechanism

The surgical construct includes a reinforcement material, such as suture tape, coupled with a flexible connector and at least one eyelet. The eyelet, which may be part of a shuttle/pull device, facilitates the formation of a splice that locks the flexible coupler in place after suturing. This arrangement allows for a self-locking mechanism that eliminates the need for traditional knots, thus simplifying the surgical process and improving fixation strength.

Applications and Benefits

These surgical constructs are particularly beneficial for soft tissue to bone fixation in various reconstructive surgeries, such as ACL reconstructions, Achilles tendon repairs, and other ligament and tendon repairs. The knotless design not only reduces the complexity of the procedure but also enhances the durability and reliability of the repair by providing consistent tension and compression across the sutured area.

Methodology

The methods described involve suturing tissue to the reinforcement material with a flexible coupler, followed by locking the coupler in a knotless manner. This process may include forming one or more splices, which are partially or fully housed within the reinforcement material. The constructs can be pre-attached to fixation devices like buttons or screws, or attached during the surgical procedure, offering versatility and ease of use.

Illustrations and Embodiments

The accompanying figures illustrate various embodiments and steps involved in the use of these surgical constructs. Figures depict different views and configurations of the constructs, assemblies, and methods, providing a comprehensive visual guide to their application in surgical settings. The constructs can be tailored to specific surgical needs by adjusting the length and width of the reinforcement material, ensuring optimal fit and function for diverse anatomical structures.
