Enhanced Repositionable Endoluminal Support Structure for Improved Prosthetic Device Delivery
Legal Citation
Summary of the Inventive Concept
An innovative repositionable endoluminal support structure that offers enhanced flexibility, radial force, and real-time feedback, enabling precise and efficient delivery of prosthetic devices in various medical procedures.
Background and Problem Solved
The original patent for the repositionable endoluminal support structure and its applications had limitations in terms of flexibility, radial force, and real-time feedback. The new inventive concept addresses these limitations by incorporating advanced materials, sensors, and control systems, enabling improved prosthetic device delivery and reduced procedural risks.
Detailed Description of the Inventive Concept
The enhanced repositionable endoluminal support structure comprises a plurality of longitudinal strut members interconnected by swivel joints, fabricated from shape-memory alloys that allow for repeated expansion and contraction without compromising structural integrity. The structure includes sensors providing real-time feedback on its position and orientation, and is coated with biocompatible materials to reduce thrombogenicity and promote endothelialization. The system features a control unit integrated with a visualization system, enabling real-time adjustments to the structure's position and orientation. The strut members are designed to provide a predetermined amount of radial force to maintain the structure's shape and position within a body lumen.
Novelty and Inventive Step
The new claims introduce novel features such as enhanced flexibility, real-time feedback, and advanced materials, which are not present in the original patent. These innovations provide a significant improvement in prosthetic device delivery, making the new inventive concept non-obvious and novel compared to the original patent.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include different types of sensors, control systems, or visualization tools. Variations could also include different materials or geometries for the strut members, or additional features such as temperature control or drug elution capabilities.
Potential Commercial Applications and Market
The enhanced repositionable endoluminal support structure has significant commercial potential in the medical device industry, particularly in the fields of cardiovascular, neurovascular, and peripheral vascular interventions. The target market includes hospitals, clinics, and medical research institutions, with potential for widespread adoption and revenue growth.
