Catheter assembly for blood clot removal
An aspiration system for aspirating blood clots from a human body has a power source, an aspiration pump, and an electrical motor coupled to the power source and the aspiration pump, wherein the aspiration pump is pulsed at a frequency below 10 Hz.
1. An aspiration system for aspirating blood clots from a human body, comprising:
an aspiration catheter;
a power source;
a liquid diaphragm aspiration pump connected to the aspiration catheter;
an electrical motor coupled to the power source and the aspiration pump; and
wherein the aspiration pump is pulsed on and off at a frequency between 6-7 Hz; and
a printed circuit board located between the power source and the electrical motor to convert voltage from the power source into pulsing voltage supplied to the motor; and wherein the power source provides 6-24 VDC.
2. The aspiration system of claim 1 , wherein the voltage provided to the motor from the power source is pulsed.
3. The system of claim 1 , wherein the power source is a battery.
4. The system of claim 1 , wherein the power source is a line power.
5. The system of claim 1 , further including a clot collection bag coupled to the aspiration pump assembly.
6. The system of claim 1 , wherein the electrical motor rotates the aspiration pump at a speed below 2000 RPM.
