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. 11,857,737.

Summary of the Inventive Concept

The present inventive concept discloses a series of direct improvements and enhancements to the original low-profile occlusion balloon catheter system, addressing limitations in navigation, pre-conditioning, and procedural safety. The novel system features advanced balloon materials, integrated temperature control, adjustable occlusion balloon diameter, retractable guidewires, and pressure-sensing elements, collectively providing a more efficient, safer, and more effective vascular occlusion procedure.

Background and Problem Solved

The original low-profile occlusion balloon catheter system, as described in the original patent, has inherent limitations in navigating narrow vasculature, controlling perfusion and occlusion, and ensuring procedural safety. The present inventive concept addresses these limitations by introducing a novel balloon material, integrating temperature control, and incorporating advanced features that enhance the overall performance and safety of the vascular occlusion procedure.

Detailed Description of the Inventive Concept

The enhanced low-profile occlusion balloon catheter system comprises a novel balloon material with improved elasticity and reduced friction, allowing for smoother navigation through narrow vasculature. The system also features an integrated temperature control feature, enabling real-time monitoring and adjustment of perfusion and occlusion. Furthermore, the occlusion balloon diameter is adjustable, facilitating precise control over blood flow and pressure during the vascular occlusion procedure. Additionally, the system incorporates a retractable guidewire, reducing the risk of guidewire-related complications and improving overall procedural safety. A pressure-sensing element provides real-time feedback on occlusion pressure, enabling more accurate and effective vascular pre-conditioning.

Novelty and Inventive Step

The present inventive concept introduces a novel combination of features that are not obvious from the original patent. The advanced balloon material, integrated temperature control, adjustable occlusion balloon diameter, retractable guidewire, and pressure-sensing element collectively provide a significant improvement over the original system, addressing the inherent limitations and providing a more efficient, safer, and more effective vascular occlusion procedure.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include variations in the balloon material, temperature control mechanisms, and pressure-sensing elements. Additionally, the system could be adapted for use in different vascular occlusion procedures, such as neurovascular or cardiovascular interventions. Other variations may include the use of different guidewire materials, shapes, or configurations, or the integration of additional sensors or monitoring systems.

Potential Commercial Applications and Market

The enhanced low-profile occlusion balloon catheter system has significant commercial potential in the medical device industry, particularly in the fields of vascular intervention, cardiology, and neurology. The system's improved performance, safety, and efficiency make it an attractive solution for hospitals, clinics, and medical research institutions. The market for vascular occlusion catheters is growing, driven by an increasing demand for minimally invasive procedures and the need for more effective and efficient vascular pre-conditioning techniques.
