Anastomotic Coupler Ring for Vascular Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional anastomotic techniques, such as sutures and staples, often result in complications like leakage, stenosis, and thrombosis due to micro-motion and size mismatch issues, particularly in vascular anastomoses, and require specialized equipment, which can lead to additional surgical challenges and complications.
Innovation Solution
An anastomotic coupler system comprising a ring and a fixation device with a cartridge and fasteners that align and secure tubular structures, allowing for a secure, leak-proof connection between tubular structures, accommodating size variations with adjustable components and preventing fluid leakage through precise alignment and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sutures and staples are used for anastomosis, then the connection can be established, but complications like leakage, stenosis, and thrombosis occur due to micro-motion and size mismatch
Solution Approach 1:
The patent introduces an intermediate coupler device with a ring structure that mediates between the two tubular structures. The ring acts as a mediator that receives both tubular structures and provides a stable platform for fastening, eliminating direct suture/staple contact that causes micro-motion and complications. The intermediate ring structure allows for secure attachment while maintaining luminal patency and preventing harmful factors.
Solution Approach 2:
The coupler device is segmented into distinct functional components: a ring structure for receiving tubular structures, a fastening mechanism for securing the ring to the tubular structures, and a luminal opening for maintaining flow. This segmentation allows each component to perform its specific function optimally, with the ring providing structural stability and the fastening mechanism eliminating micro-motion without causing tissue damage.
2Reliability
If conventional sutures and staples are used, then anastomosis can be completed, but specialized equipment is required leading to additional surgical challenges
Solution Approach 1:
The coupler device is designed as a self-contained system where the ring structure and fastening mechanism work together as an integrated unit. The device serves itself by providing both the structural ring for receiving tubular structures and the fastening capability in a single implantable unit, eliminating the need for complex external equipment during the anastomosis procedure.
3Reliability
If conventional techniques are used for anastomosis, then connection can be established, but the process is time-consuming and less secure
Solution Approach 1:
The ring structure is pre-formed and prepared before insertion, with the luminal opening and fastening mechanisms already in place. This preliminary preparation allows for rapid deployment during surgery, as the device can be inserted and secured without requiring time-consuming construction or assembly steps. The pre-formed ring structure immediately provides the secure connection needed, eliminating post-insertion adjustments and extending the procedure time.

AI summary
An anastomotic coupler is provided. A ring can include a plurality of receiving portions. A fixation device includes a cartridge. The cartridge includes a plurality of fasteners. The ring is aligned with the cartridge such that the receiving portions are aligned with the fasteners. Upon actuation of the fixation device, the fasteners puncture the tubular structure and are received by the receiving portions such that the tubular structure is coupled with the ring.
