Integrated Cutting and Suturing Device for Visceral Wall Perforation Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transluminal procedures are time-consuming and require multiple instruments for forming and closing visceral wall perforations, posing risks such as bleeding and infection due to the complexity of accessing and sealing bodily cavities.
Innovation Solution
A medical device with an integrated cutting and suturing tool, featuring a plurality of needles connected to sutures, allows for simultaneous perforation formation and closure of visceral walls, reducing procedure time and instrument count by advancing through the bodily lumen to form a perforation, passing needles through the visceral wall, and retracting to close it with sutures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate instruments are used for cutting and suturing visceral walls, then each function can be performed with a specialized tool, but the procedure time increases and the number of instruments required increases
Solution Approach 1:
The patent combines cutting and suturing functions into a single integrated device. The device includes a cutting tool with a needle-knife that can incise tissue, and a suture deployment mechanism with multiple needles and sutures that can be advanced through the same device body. This integration allows both cutting and suturing to be performed without exchanging instruments, directly resolving the contradiction by maintaining functional specialization while eliminating procedure time loss from instrument changes.
Solution Approach 2:
The device is designed as a multi-functional instrument that can perform multiple surgical functions through a single access point. The device body can accommodate both cutting tools for creating perforations and suture deployment mechanisms for closing those perforations. This universality allows the single device to replace multiple specialized instruments, reducing both procedure time and the number of instruments required while maintaining the reliability of specialized functions.
2Reliability
If multiple separate instruments are used for forming and closing perforations, then each operation can be optimized with dedicated tools, but the complexity of the procedure and number of instruments increase
Solution Approach 1:
The patent merges multiple surgical operations into a single integrated device platform. The device includes a reusable device body that can accommodate different cutting tools and suture deployment mechanisms. By combining these functions in one device, the patent reduces the number of separate instruments from multiple specialized tools to a single multi-functional device, thereby reducing procedural complexity while maintaining operational optimization through specialized components within the integrated system.
3Reliability
If sequential use of cutting and suturing instruments is employed, then each instrument can be used at its optimal time, but the overall procedure duration increases
Solution Approach 1:
The patent enables continuous surgical action by eliminating the interruption between cutting and suturing operations. The integrated device allows the surgeon to transition seamlessly from cutting with the needle-knife to deploying sutures without withdrawing or changing instruments. This continuity maintains the optimal performance of each function while significantly improving procedure efficiency by eliminating downtime between operations, directly addressing the contradiction between instrument performance and procedural productivity.
4Reliability
If multiple instruments are used to access and seal bodily cavities, then comprehensive control can be achieved, but the risk of complications from procedural complexity increases
Solution Approach 1:
The patent combines multiple surgical functions into a single device that accesses the body through one perforation site. This integration reduces the number of separate instrument insertions and manipulations required, thereby minimizing tissue trauma and the risk of complications such as infection or bleeding. The device maintains comprehensive control through its integrated design, allowing cutting, suture deployment, and sealing to be performed through a single controlled access point, thus reducing complication risks while preserving control precision.

AI summary
A medical device and method for performing transluminal procedures that reduces procedure time as well as the number of instruments used is disclosed. An elongate medical device has both a cutting tool and a suturing tool disposed at a distal end of the elongate medical device. The suturing tool includes a plurality of needles connected to one or more sutures. The elongate medical device is advanced through a bodily lumen to a position proximate the visceral wall. A perforation is formed in the visceral wall using the cutting tool. The elongate medical device and its suturing tool are advanced through the perforation and a plurality of needles are passed through the visceral wall around the periphery of the perforation. The plurality of needles are withdrawn through the bodily lumen and the perforation is closed using the suture.
