Advanced Looped Wire Systems for Niche Endovascular Applications
Legal Citation
Summary of the Inventive Concept
This inventive concept adapts the original looped wire design for specialized, high-stakes endovascular procedures in extreme weather conditions, high-security environments, disaster relief operations, high-altitude settings, and areas with limited access to medical facilities.
Background and Problem Solved
The original looped wire design for endograft systems, as described in the parent patent, has limitations in addressing the unique challenges posed by these niche applications. The new inventive concept addresses these limitations by incorporating specialized materials, coatings, and mechanisms to ensure the reliability and effectiveness of the looped wire system in these demanding environments.
Detailed Description of the Inventive Concept
The advanced looped wire system comprises a plurality of pre-cannulation wires, each featuring a looped wire design adapted to withstand extreme weather conditions, high-security environments, or other specialized requirements. The wires are designed to maintain flexibility, visibility, and quick-release capabilities in low-light, high-wind, or low-temperature conditions. The system may include specialized coatings to prevent ice formation, enhanced visibility under low-light conditions, or quick-release mechanisms for emergency deployment.
Novelty and Inventive Step
The new inventive concept introduces novel adaptations of the original looped wire design to address the specific challenges of niche endovascular applications. The combination of specialized materials, coatings, and mechanisms provides a non-obvious solution to the limitations of the original design, offering a significant improvement in the reliability and effectiveness of endovascular procedures in these demanding environments.
Alternative Embodiments and Variations
Alternative embodiments of the advanced looped wire system could include variations in wire materials, coatings, or mechanisms tailored to specific niche applications. For example, a system for high-altitude environments could incorporate a specialized insulation to maintain wire flexibility in low-temperature conditions, while a system for disaster relief operations could feature a simplified, quick-release mechanism for emergency deployment.
Potential Commercial Applications and Market
The advanced looped wire system has significant commercial potential in the medical device industry, particularly in the areas of endovascular aneurysm repair, thoracic endovascular aneurysm repair, and stent graft deployment. The system's ability to address the unique challenges of niche applications could expand the market for endovascular procedures, providing a competitive advantage for manufacturers and improving patient outcomes in these critical environments.
