Anatomic Wall Port for Transluminal Access and Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical techniques require incisions through the skin and muscle, leading to significant patient recovery periods and scarring, while minimally invasive methods through natural orifices are limited in accessing abdominal cavities effectively.
Innovation Solution
Development of transluminal devices and ports that allow insertion through natural orifices, with mating elements and seals to secure the device within the anatomic wall, preventing contamination and infection, and enabling passage of surgical tools while maintaining a seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open surgical techniques or laparoscopic procedures are used to access the abdominal cavity, then effective access to the abdominal cavity is achieved, but significant patient recovery periods and post-surgical scarring result
Solution Approach 1:
The device segments the access path into two distinct parts: a natural orifice entry path and a controlled anatomic wall penetration path. This allows the procedure to benefit from both natural orifice access (minimizing external scarring) and controlled wall penetration (ensuring effective abdominal cavity access with minimal tissue damage)
Solution Approach 2:
The anatomic wall port acts as an intermediary structure between the natural orifice and the abdominal cavity. It provides a controlled interface that allows tool passage while maintaining sealing, thereby reducing tissue trauma compared to traditional open surgery while ensuring effective access
2Object-affected harmful factors
If access through a natural body orifice is used, then minimally invasive surgical access is achieved, but effective access to abdominal cavities is limited
Solution Approach 1:
The device transitions from purely luminal navigation to a three-dimensional approach by penetrating through the anatomic wall. This dimensional change allows the device to exit the natural orifice, traverse through the wall, and access the abdominal cavity directly, overcoming the limitations of luminal-only approaches
3Ease of operation
If the port permits passage of the transluminal device through the anatomic wall, then surgical tool access is enabled, but passage of biomaterials may cause contamination and infection
Solution Approach 1:
The port incorporates a flexible sealing membrane that can dynamically respond to tool passage. The membrane flexes to allow instrument insertion and removal while automatically sealing around the tools, thereby preventing biomaterial leakage and maintaining sterility between procedures
Solution Approach 2:
The sealing mechanism is designed to automatically seal around the transluminal device without requiring additional sealing steps or components. The port's internal geometry and flexible materials enable self-sealing as the device is inserted or removed, reducing the risk of contamination

AI summary
Disclosed herein are various systems and methods for traversing an anatomic wall. A system can include a port that mates with an anatomic wall and provides a lumen for the passage of a guide tube of a transluminal device. The port can inhibit the passage of biological materials through the anatomic wall. Further described herein are methods for implanting the port and/or for inserting the transluminal device into a body cavity.
