This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,219.

Summary of the Inventive Concept

Improved systems and methods for augmenting vertebral bodies, featuring advanced sensing, real-time feedback, and enhanced stability, to provide better patient outcomes and reduced procedural time.

Background and Problem Solved

The original patent disclosed systems and methods for manipulating tissue, particularly for treating vertebral compression fractures. However, these systems had limitations, such as inadequate conduit placement, insufficient bone integration, and potential tissue trauma. The new inventive concept addresses these limitations by introducing advanced features that improve the overall procedure and patient experience.

Detailed Description of the Inventive Concept

The enhanced system comprises an access cannula with a built-in sensor for monitoring bone density, a steerable assembly with a real-time feedback mechanism to optimize conduit placement, and a deformable conduit assembly with a reinforced distal end for improved stability. The system enables more accurate and efficient navigation through cancellous bone, reducing tissue trauma and procedural time. The deformable conduit assembly features a variable stiffness profile, allowing for better adaptability to different bone densities. Additionally, the system includes an integrated irrigation system, precision-controlled curvature, and a self-expanding structure, further enhancing the overall procedure.

Novelty and Inventive Step

The new claims introduce significant advancements over the original patent, including the incorporation of sensing technology, real-time feedback, and advanced conduit design. These features provide a substantial improvement in the overall procedure, making the new inventive concept novel and non-obvious.

Alternative Embodiments and Variations

Alternative embodiments may include variations in the sensor technology, such as using different types of sensors or integrating multiple sensors for enhanced data collection. Other variations may involve modifications to the steerable assembly, such as incorporating haptic feedback or using different materials for the deformable conduit. Additionally, the system could be adapted for use in other orthopedic procedures, such as joint reconstruction or osteotomy.

Potential Commercial Applications and Market

The enhanced systems and methods for vertebral body augmentation have significant commercial potential in the orthopedic and spine surgery markets. The improved procedure and reduced procedural time can lead to increased adoption and market share. The target industries include medical device manufacturers, hospitals, and outpatient surgery centers.
