Advanced Systems and Methods for Aspirating from a Body Lumen

The present inventive concept relates to enhanced systems and methods for aspirating fluid from a body lumen, providing improved control, efficiency, and safety in clot removal procedures.

The original patent disclosed systems and methods for aspirating fluid from a body lumen, but had limitations in terms of vacuum control, ergonomic design, and flow restrictions. The present inventive concept addresses these limitations by introducing adjustable vacuum locks, ergonomic grip designs, integrated valve systems, and self-cleaning mechanisms, among other advancements.

The new systems and methods comprise a syringe device with an adjustable vacuum lock, allowing for fine-tuned control over the aspiration force. The ergonomic grip design facilitates one-handed operation, reducing fatigue and improving procedural efficiency. The internal syringe barrel member features an integrated valve system, minimizing flow restrictions and enabling efficient clot removal. The plunger includes a plunger seal with a self-cleaning mechanism, reducing the risk of clogging and improving overall system reliability. Additionally, some embodiments feature a built-in pressure sensor, providing real-time feedback to the user on the aspiration force, and a graphical user interface displaying the pressure data to facilitate optimal aspiration techniques.

The new inventive concept introduces several novel features, including adjustable vacuum locks, integrated valve systems, and self-cleaning mechanisms, which provide significant improvements over the original patent. These advancements enable more efficient, safer, and more effective clot removal procedures, making the new inventive concept non-obvious and novel compared to the prior art.

Alternative embodiments of the inventive concept may include variable stroke length syringe devices, controlled injection features for clot fragmentation, and customized ergonomic grip designs for specific user needs. These variations ensure broad conceptual coverage and adaptability to different procedural requirements.

The advanced systems and methods for aspirating from a body lumen have significant commercial potential in the medical device industry, particularly in the areas of interventional cardiology, neurology, and peripheral vascular disease treatment. The target market includes hospitals, clinics, and medical research institutions, with potential for widespread adoption and revenue growth.
