Summary of the Inventive Concept

The present inventive concept discloses novel improvements to embolic capture devices for treating blocked blood vessels, enhancing their efficiency, safety, and effectiveness in minimally invasive catheter-based interventions.

Background and Problem Solved

The original patent disclosed embolic capture devices with limitations in terms of embolus containment, radial strength, and flexibility. The present inventive concept addresses these limitations by introducing an improved mesh basket design, novel strut patterns, and thrombolytic coatings, reducing the risk of distal complications and enhancing embolus removal efficiency.

Detailed Description of the Inventive Concept

The inventive concept comprises a catheter-based emboli removal device with an improved mesh basket design featuring enhanced radial strength and flexibility. The device incorporates a novel strut pattern that enables efficient embolus capture and removal. Additionally, the device can be deployed with a proximal-to-distal motion, reducing the risk of embolus dislodgement. A detachable embolic capture device can be released from the catheter, allowing for more precise control and reduced risk of vessel damage. Furthermore, the device can be coated with a thrombolytic agent, enhancing the efficacy of embolus removal and reducing the risk of re-occlusion.

Novelty and Inventive Step

The novel features of the inventive concept include the improved mesh basket design, novel strut patterns, and thrombolytic coatings, which provide a non-obvious solution to the limitations of the original patent. The proximal-to-distal deployment motion and detachable embolic capture device also introduce new and innovative aspects to the field.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the mesh basket design, strut patterns, and thrombolytic coatings. Additionally, the device could be adapted for use in different vascular systems, such as coronary or peripheral vessels.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the field of minimally invasive catheter-based interventions for treating blocked blood vessels. The device could be marketed to hospitals, clinics, and medical professionals specializing in interventional cardiology and neurology.
