Tissue Cutting Device for Minimally Invasive Septa Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aesthetic treatment methods for cellulite and other skin imperfections are often invasive, traumatic, and yield unpredictable results, with limited effectiveness and increased risk of trauma, bruising, and lengthy recovery times, while existing devices for scar treatment and facial procedures often disrupt non-target tissues and require multiple entry sites.
Innovation Solution
A tissue cutting and slicing system with a distal end device mounted on a shaft, allowing for precise engagement and modification of fibrous septa through stretching, re-orienting, tearing, or cutting, combined with localized fat disruption or removal, using a handle assembly with actuatable configurations for minimal impact on surrounding tissues and efficient treatment through a single entry site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional treatment devices are inserted within tissue close to the interventional site and travel within tissue to the site, then treatment can be delivered to the target area, but non-target tissue is cut or disrupted and multiple skin entry sites are created
Solution Approach 1:
A subcutaneous tunneling device is used as an intermediary tool to create a protected pathway through the skin and into the subcutaneous tissue. The tunneling device allows the treatment device to reach the target septa area without requiring multiple skin entry sites, as the tunneling device creates a single access point and protected channel through which the treatment device can be advanced to the target location deep within the tissue layers
Solution Approach 2:
The treatment system is divided into separate functional components: a tunneling device for creating the access pathway, and a separate treatment device for engaging and cutting septa. This segmentation allows each component to be optimized for its specific function while working together to achieve treatment goals with minimal tissue disruption and a single skin entry site
2Reliability
If blades or needles are used to cut septa in the subdermal region, then cellulite appearance is improved, but the procedure becomes labor intensive and causes significant tissue trauma
Solution Approach 1:
The treatment device combines multiple functions into a single integrated tool: it includes a hook for engaging septa, a blade for cutting septa, and a reamer for disrupting fat tissue. This merging of functions into one device reduces procedure complexity and tissue trauma compared to using separate blades, needles, and tools, while maintaining effective cellulite treatment results
Solution Approach 2:
The treatment device is designed to continuously engage, cut, and disrupt tissue in a single continuous motion through the subcutaneous space. The device can transition smoothly between hooking septa, cutting them with the blade, and reaming fat tissue, eliminating the need for multiple separate procedures and reducing overall procedural trauma

AI summary
Systems and methods for aesthetic treatment of skin including an apparatus that applies or a method involving separating tissue to eliminate or reduce the appearance of unwanted features. In one approach, an interventional tool is placed between tissue layers to engage and treat connecting tissue layers. Focal fat tissue collection is conducted as needed independently or supplemental to the treatment of targeted septa.
