Apertured Suture Structure for Knotless High-Friction Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sutures require a multi-step process for connection to tissue or surgical devices, which can be challenging and time-consuming, and often lack sufficient friction to prevent slippage.
Innovation Solution
A suture construct with apertures through which a portion of the suture is passed to form surface features, such as ridges or bumps, increasing friction for secure coupling with tissue or devices without the need for knots.

1Productivity
If traditional multi-step suture connection process is used, then connection can be achieved, but the process is challenging and time-consuming
Solution Approach 1:
The suture features (ridges, bumps, or other surface irregularities) are pre-formed on the suture body before surgical implantation. This preliminary preparation eliminates the need for complex intraoperative manipulation and knot-tying, allowing surgeons to simply pass the suture through tissue and secure it with a single continuous motion, thereby dramatically reducing surgical time and procedural difficulty
Solution Approach 2:
The invention extracts and eliminates the complex multi-step knot-tying process from traditional suture procedures. By incorporating friction-enhancing features directly into the suture body, the patent removes the need for separate knot-tying steps, simplifying the overall surgical workflow while maintaining secure connection
2Reliability
If traditional suture without friction features is used, then suture can be passed through tissue, but slippage occurs due to insufficient friction
Solution Approach 1:
The suture body incorporates localized friction-enhancing features (ridges, bumps, or other surface irregularities) at specific positions along its length. These localized features create high-friction zones that engage with tissue or surgical devices to prevent slippage, while the rest of the suture maintains its original smooth properties for easy passage through tissue
Solution Approach 2:
The invention modifies the surface parameters of the suture body by adding geometric features that increase surface area and roughness. This parameter change transforms the suture from a smooth surface with low friction to one with controlled high-friction zones, enhancing grip and preventing slippage without compromising the suture's flexibility or passage capability

AI summary
Disclosed herein is a suture for a surgical procedure that can include a body. The body can comprise an elongate strand. The body can have an aperture therethrough at a first portion of the elongate strand. A second portion of the elongate strand adjacent the first portion can be passed through the first aperture to create a feature along an exterior surface of the body.
