Integrated Balloon-Filler Kyphoplasty Device for Vertebral Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kyphoplasty procedures face challenges in efficiently creating and maintaining the desired anatomic height of a fractured vertebral body during balloon inflation and bone filler delivery, often leading to loss of restored height.
Innovation Solution
A multi-functionality device integrating a balloon and bone filler into a single unit, allowing simultaneous or sequential inflation and filling, with a dual port system for independent fluid delivery, and a connection system for compact instrument engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate devices are used for balloon inflation and bone filler delivery, then each device can be optimized for its specific function, but the procedure becomes more complex and time-consuming with multiple instrument changes
Solution Approach 1:
The patent combines the balloon device and bone filler delivery system into a single integrated kyphoplasty device. The balloon is positioned within the vertebral body cavity and the bone filler is delivered through the same device structure, allowing both functions to be performed with one instrument rather than requiring separate devices for each step of the procedure.
Solution Approach 2:
The kyphoplasty device is designed with multi-functionality, serving both as a balloon inflation device for cavity expansion and height restoration, and as a bone filler delivery system. This universal device performs multiple functions that previously required separate specialized instruments, simplifying the overall procedure.
2Reliability
If balloon is inflated first to restore height, then bone filler is delivered separately, but this sequential approach may result in loss of restored height during the transition between steps
Solution Approach 1:
The integrated device allows continuous action from balloon inflation through bone filler delivery without interruption or instrument removal. The balloon is inflated to restore vertebral height, and immediately afterward bone filler is delivered through the same device while the balloon remains in place, maintaining continuous support and preventing height loss during the transition between steps.
3Productivity
If multiple instruments are used for cavity creation, balloon inflation, and filler delivery, then each step can be performed with specialized tools, but instrument interference and procedural complexity increase
Solution Approach 1:
The patent merges the cavity preparation, balloon inflation, and bone filler delivery functions into a single integrated device structure. This eliminates the need to coordinate multiple separate instruments and reduces instrument interference, thereby improving procedural efficiency despite the enhanced functionality of the single device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the kyphoplasty procedure by maintaining vertebral body height and ensuring complete filling without loss, while minimizing instrument interference and providing a reliable, efficient process.
Implementation Method 1
The balloon is then inflated, for example, by injecting a solution into the balloon, thereby expanding the drilled cavity into a desired size within the vertebral body
Implementation Method 2
the kyphoplasty system can be configured to maintain a desired anatomic height (e.g., after a balloon is inserted to expand a cavity to a desired height) before and during the delivery of cement to the expanded cavity

AI summary
A kyphoplasty system includes various instruments which can be selectively used in a surgical theater (e.g., during a surgical operation on a patient) or a surgical training environment. The kyphoplasty system can include one or more of a kyphoplasty apparatus, a prone table mat, a connector system, a bone introducer needle, and a biopsy device. The kyphoplasty system may also include a training system for use in the training environment.
