Needle-Mounted Balloon System for Bone Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone expansion devices for procedures like vertebroplasty and kyphoplasty require separate cannula and balloon components, which are cumbersome and time-consuming, and do not provide adequate protection for the balloon during insertion.
Innovation Solution
A needle-mounted balloon system integrating a cannula and expandable balloon, where the balloon is protected by an outer sheath and can be inflated and deflated to create space within the bone for filler material injection, reducing procedural complexity and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cannula and balloon components are used, then the balloon can be protected during insertion, but the procedure becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines the cannula and balloon into a single integrated needle-mounted balloon system. The balloon is mounted directly on the cannula assembly, eliminating the need for separate components. This integration maintains protection during insertion while simplifying the procedure by reducing the number of steps required to assemble and position components.
Solution Approach 2:
The integrated needle-mounted balloon system performs multiple functions within a single device: the cannula provides insertion and protection, the balloon provides space creation, and the system enables both vertebroplasty and kyphoplasty procedures. This multi-functionality reduces procedural complexity by consolidating what would otherwise require multiple separate tools and steps.
2Reliability
If separate cannula and balloon components are used, then the balloon can be protected during insertion, but the procedure becomes time-consuming
Solution Approach 1:
The patent combines the cannula and balloon into a single integrated needle-mounted balloon system. The balloon is mounted directly on the cannula assembly, eliminating the need for separate components. This integration maintains protection during insertion while simplifying the procedure by reducing the number of steps required to assemble and position components.
Solution Approach 2:
The balloon is pre-mounted on the cannula assembly before insertion, so that protection and space creation capabilities are already integrated into the insertion device. This preliminary integration eliminates the need for separate assembly steps during the procedure, reducing overall procedural time while maintaining balloon protection.
3Device complexity
If an integrated needle-mounted balloon system is used, then procedural complexity is reduced, but the balloon may not be adequately protected during insertion
Solution Approach 1:
The balloon is nested within the cannula structure during insertion, with the cannula acting as a protective sheath around the balloon. This nested configuration allows the balloon to be protected during insertion while maintaining integration that simplifies the procedure. The cannula's structural integrity provides protection to the balloon without requiring separate protective components.
Solution Approach 2:
The patent combines the cannula and balloon into a single integrated needle-mounted balloon system. The balloon is mounted directly on the cannula assembly, eliminating the need for separate components. This integration maintains protection during insertion while simplifying the procedure by reducing the number of steps required to assemble and position components.
4Reliability
If traditional separate components are used, then adequate protection for the balloon is provided, but treatment costs increase
Solution Approach 1:
The patent combines the cannula and balloon into a single integrated needle-mounted balloon system. The balloon is mounted directly on the cannula assembly, eliminating the need for separate components. This integration maintains protection during insertion while simplifying the procedure by reducing the number of steps required to assemble and position components.
Solution Approach 2:
The integrated system is designed as a disposable unit that eliminates the need for separate reusable and disposable components. By combining all necessary elements into a single disposable assembly, the system reduces costs associated with multiple components while maintaining adequate protection during insertion.

Function Achieved in This Case
The integrated system simplifies the procedure, reduces recovery time, minimizes patient discomfort, and lowers treatment costs by combining components and protecting the balloon during insertion, enhancing ease of use and efficiency.
Implementation Method 1
an expandable member coupled to the cannula tube portion. The expandable member is reconfigurable between a diametrically contracted configuration and a diametrically expanded configuration

AI summary
A needle-mounted balloon system can include a cannula and a stylet. The cannula may include a handle and an outer sheath, and the outer sheath may be configured to retract and expose at least a portion of an expandable member. The stylet may include a stylet needle and a sharp distal tip portion. The stylet needle may be used to insert the system into a body structure, after which the stylet may be disengaged from the cannula. The expandable member may then be exposed and inflated to create a space in the body structure. Filler material may be injected through the cannula to the open space in an effort to stabilize an injured or otherwise destabilized portion of the body structure.
