Enhanced Embolic Capture Devices for Minimally Invasive Catheter-Based Interventions

The present inventive concept relates to improved embolic capture devices and methods for treating blocked blood vessels, particularly in the brain and vessel systems perfusing the same, by incorporating advanced materials and design features to enhance radial expansion, embolus containment, visualization, and retrieval safety.

The original patent disclosed embolic capture devices with limitations in radial expansion, embolus containment, and visualization. The present inventive concept addresses these limitations by introducing a shape-memory alloy mesh basket, proximal occlusion balloon, radiopaque marker, and enhanced visualization features, thereby improving the safety and efficacy of minimally invasive catheter-based interventions.

The enhanced embolic capture device features a mesh basket made of a shape-memory alloy, enabling enhanced radial expansion and embolus containment. The device may further comprise a proximal occlusion balloon to prevent distal embolus migration during retrieval. Additionally, a radiopaque marker integrated into the mesh basket provides improved fluoroscopic visualization during deployment and retrieval. The inventive concept also encompasses a system for treating blocked blood vessels, comprising the enhanced embolic capture device, a guidewire, and a control unit for monitoring and controlling the device's deployment and retrieval.

The new claims introduce novel features such as the shape-memory alloy mesh basket, proximal occlusion balloon, and radiopaque marker, which provide enhanced radial expansion, embolus containment, and visualization capabilities, thereby distinguishing the inventive concept from the original patent.

Alternative embodiments may include varying the shape-memory alloy composition, mesh basket geometry, or occlusion balloon design. Variations may also include integrating additional features, such as sensors or actuators, to further enhance device performance and safety.

The enhanced embolic capture devices and systems have significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology, neurology, and peripheral vascular interventions. The target market includes hospitals, clinics, and medical research institutions.
