PULSATILE ASPIRATION SYSTEM USING A STATIC VACUUM SOURCE WITH INTERMITTENT INJECTION OF A PRESSURE PULSE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18441798 titled 'PULSATILE ASPIRATION SYSTEM USING A STATIC VACUUM SOURCE WITH INTERMITTENT INJECTION OF A PRESSURE PULSE
Simplified Explanation: The patent application describes a pulsatile aspiration system consisting of a catheter and pump system. The system controls negative and positive fluid pressure independently to create a pulsatile aspiration waveform at the catheter's distal end.
- The system includes a catheter with an outer wall, proximal and distal sections, and an internal wall dividing the proximal section into a main lumen and an auxiliary lumen.
- A pump system is in fluid communication with the catheter, controlling negative and positive fluid pressure in the main and auxiliary lumens to produce a pulsatile aspiration waveform.
- The waveform varies between maximum aspiration pressure and maximum positive pressure, achieved by balancing negative and positive fluid pressures at the catheter's distal end.
Potential Applications: 1. Medical procedures requiring precise fluid pressure control. 2. Minimally invasive surgeries where pulsatile aspiration is beneficial. 3. Research applications in fluid dynamics and pressure regulation.
Problems Solved: 1. Lack of control over pulsatile aspiration in medical procedures. 2. Difficulty in achieving variable pressure waveforms in catheter systems.
Benefits: 1. Enhanced precision and control in medical procedures. 2. Improved efficiency and effectiveness in minimally invasive surgeries. 3. Facilitates research in fluid dynamics and pressure modulation.
Commercial Applications: Potential commercial applications include medical device manufacturing, research institutions, and hospitals for various surgical procedures requiring precise fluid pressure control.
Questions about Pulsatile Aspiration Systems: 1. How does the pulsatile aspiration system improve medical procedures? 2. What are the key components of a pulsatile aspiration system and how do they work together?
Frequently Updated Research: Ongoing research in fluid dynamics and medical device technology may lead to advancements in pulsatile aspiration systems, improving their efficiency and applicability in various medical procedures.
Original Abstract Submitted
A pulsatile aspiration system is herein disclosed that includes a catheter and pump system. The catheter includes an outer wall, a proximal section, a distal section, and an internal wall dividing the proximal section into a central main lumen and an auxiliary lumen. The pump system is in fluid communication with the catheter and independently controls the negative fluid pressure and the positive fluid pressure in the central main lumen and the auxiliary lumen so as to produce at the distal end of the catheter a pulsatile aspiration waveform variable between a maximum aspiration pressure and a maximum positive pressure. The maximum aspiration pressure is producible at the distal end of the catheter when the resulting pressure is exclusively negative fluid pressure, and the maximum positive pressure is producible at the distal end of the catheter when the positive fluid pressure counterbalances that of the negative fluid pressure.
