Endoscope Endcap with Support Rib for Tissue Suturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transluminal procedures face challenges in providing a suitable conduit for endoscopic suturing, maintaining sterility, insufflation, proper closure of openings in internal organs, and preventing infection, particularly due to spillage of bodily fluids and bacterial contamination.
Innovation Solution
A medical device with an endcap for an endoscope that includes a tubular shape with a side port and support rib for secure tissue anchoring, allowing for controlled suture placement and closure of perforations using a needle assembly with a tissue anchor and suture, facilitating purse-string fashion closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional open surgery or laparoscopic surgery is used to close tissue perforations, then reliable closure can be achieved, but invasive abdominal incisions and incision related complications occur
Solution Approach 1:
The endcap device serves as an intermediary tool that bridges the endoscope and tissue closure function. It provides a specialized interface with tissue engagement features (support rib, piercing aperture, side port) that enables suture placement through the gastrointestinal tract wall without external incisions, thereby achieving reliable closure while avoiding incision-related complications
2Ease of operation
If transluminal procedures are used to access body cavities, then invasive incisions are eliminated, but proper closure of openings and prevention of infection become challenging
Solution Approach 1:
The endcap device is pre-positioned on the endoscope before tissue engagement. The support rib and piercing aperture are pre-configured to guide the needle and suture through the tissue, ensuring proper closure is achieved as part of the initial transluminal access procedure rather than requiring separate closure steps
3Ease of operation
If endoscopic suturing devices are used to close perforations, then minimally invasive closure is achieved, but complex device structures and difficult tissue manipulation occur
Solution Approach 1:
The endcap device is segmented into distinct functional components: the tubular body for endoscope attachment, the support rib for tissue engagement, the piercing aperture for needle passage, and the side port for suture exit. This segmentation allows each component to perform its specific function efficiently while keeping the overall device manageable and relatively simple in structure

AI summary
Medical systems, devices and methods are disclosed for suturing a perforation in tissue, that may be employed endoscopically and/or laparoscopically, and that offer simple, reliable and controllable placement of suture around a perforation for complete closure thereof. One embodiment of the medical device generally includes an endcap for use with an endoscope to suture an opening in tissue using a tissue anchor. The endcap has a tubular shape defined by an annular sidewall, and the sidewall defines an interior space. A side port is further defined by the annular sidewall and is in communication with the interior space. The side port is sized to receive and locate the tissue within the interior space for suturing. A support rib is positioned within the interior space and distal to the side port. The support rib and sidewall define a piercing aperture therebetween that supports the tissue being sutured.
