Implantable Access Port with Rotatable Anchor and Delivery Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical implantation procedures for devices like gastric bands require complex and invasive methods for attaching access ports, which are time-consuming and involve large incisions, posing challenges for quick and efficient implantation.
Innovation Solution
A system comprising an implantable access port with a rotatable anchor mechanism and a delivery tool that allows for secure attachment to bodily tissue using a cam system and cable mechanism, enabling rapid deployment and potential reversibility, facilitating minimal incision implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional complex and invasive methods are used for attaching access ports, then secure attachment is achieved, but the procedure becomes time-consuming and requires large incisions
Solution Approach 1:
The access port device is divided into separate functional components: the port body, the anchor mechanism with multiple individual anchors, and the delivery tool. This segmentation allows each component to be optimized independently and facilitates rapid deployment of the attachment mechanism without requiring complex manual manipulation during surgery
Solution Approach 2:
The anchors are pre-loaded into the delivery tool in a ready-to-deploy configuration before the surgical procedure begins. The delivery tool is designed to maintain the anchors in a compressed, sterile state until the moment of implantation, eliminating the need for time-consuming assembly or preparation steps during the actual surgical procedure
2Reliability
If traditional complex and invasive methods are used for attaching access ports, then secure attachment is achieved, but the invasiveness and tissue trauma increase
Solution Approach 1:
The attachment mechanism uses multiple small anchors distributed around the access port rather than a single large attachment structure. This segmentation allows the device to be secured through multiple small punctures in the tissue rather than requiring large incisions, significantly reducing tissue trauma while maintaining secure attachment
Solution Approach 2:
The anchors are designed with localized sharp tips for easy tissue penetration followed by expanded distal ends that provide anchoring force. This local quality differentiation allows minimal invasive insertion while achieving secure fixation at the implantation site without requiring extensive tissue disruption along the insertion path
3Productivity
If rotatable anchors with cam system and cable mechanism are used, then rapid deployment and minimal incision implantation are enabled, but the device complexity increases
Solution Approach 1:
The cam system and cable mechanism are merged into an integrated assembly within the delivery tool. The cables are routed through the delivery tool structure and connected to the cam mechanism, creating a unified deployment system that reduces the number of separate components and simplifies the overall device while maintaining rapid deployment capability
Solution Approach 2:
The delivery tool is designed to perform multiple functions: it holds and sterilizes the anchors, provides the cam mechanism for rapid deployment, and includes the cable system for actuating the anchors. This multi-functionality consolidates what could be multiple separate devices into a single tool, reducing overall system complexity while enabling rapid deployment

AI summary
A system for attaching an access port to bodily tissue includes an access port assembly and including an access port having a generally central axis. The access port assembly further includes an attachment mechanism structured to enable the access port to be attached, for example, to an abdominal muscle of a patient. The delivery tool includes a handle having a generally longitudinal axis and a delivery head structured to engage the access port assembly, and an activation mechanism for enabling deployment of the attachment mechanism when the delivery head is so engaged with the access port assembly. The delivery tool is configured such that the longitudinal axis of the handle is spaced apart from the generally central axis of the access port when the delivery head is so engaged with the access port assembly.
