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

The inventive concept disclosed herein leverages the core technology of off-axis tissue manipulation to provide novel solutions for treating skin lesions, delivering therapeutic agents to soft tissue sites, treating tendonitis, delivering cosmetic treatments, and performing minimally invasive surgical procedures.

Background and Problem Solved

The original patent disclosed systems and methods for manipulating tissue, specifically for vertebral body augmentation. However, the limitations of the original patent did not consider the application of off-axis tissue manipulation to other fields, such as soft tissue and cosmetic treatments. The new inventive concept addresses this limitation by applying the core technology to entirely new industries and problem domains.

Detailed Description of the Inventive Concept

The new inventive concept utilizes a handheld device or system comprising a deformable conduit and a steerable instrument. The deformable conduit is configured to access subcutaneous tissue, soft tissue sites, tendon tissue, or surgical sites at an angle offset from the longitudinal axis of the handheld device or system. This off-axis tissue manipulation enables the delivery of therapeutic agents, treatment of skin lesions and tendonitis, and performance of minimally invasive surgical procedures with increased precision and reduced trauma.

Novelty and Inventive Step

The new claims introduce a novel application of off-axis tissue manipulation to soft tissue and cosmetic treatments, which is non-obvious and distinct from the original patent's focus on vertebral body augmentation. The inventive step lies in the recognition of the core technology's potential for broader application and the development of new systems and methods that capitalize on this potential.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the deformable conduit, the steerable instrument, and the handheld device or system. For example, the deformable conduit could be replaced with a rigid conduit, or the steerable instrument could be substituted with a robotic arm. Additionally, the inventive concept could be adapted for use in other fields, such as orthopedic or neurological treatments.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the soft tissue and cosmetic treatment markets, with potential applications in dermatology, plastic surgery, and orthopedic medicine. The market for minimally invasive surgical procedures is also expected to benefit from this technology. The new inventive concept could lead to the development of new products, services, and treatment options, with potential for significant revenue growth and market share expansion.
