Aspiration System for Blood Clots Removal

Abstract

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 - 9 . (canceled) 
     
     
         10 . An aspiration system for removing clots from a human body, comprising:
 a power source that provides 6-24 VDC;   a diaphragm aspiration pump having a diaphragm made of rubber, wherein the diaphragm aspiration pump has an inlet to aspirate clots into the pump, and an outlet to remove clots from the pump;   an electrical rotating motor coupled to the power source and the diaphragm aspiration pump, wherein rotations of the motor are converted into vertical eccentric movement of the diaphragm; 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 diaphragm aspiration pump is pulsed on and off at a frequency between 3-10 Hz.   
     
     
         11 . The system of  claim 10 , further including an aspiration catheter. 
     
     
         12 . The system of  claim 10 , wherein the electrical motor rotates the aspiration pump at a speed below 2000 RPM. 
     
     
         13 . The system of  claim 10 , wherein the power source is a battery. 
     
     
         14 . The system of  claim 10 , wherein the power source is a line power converted to 6-24 VDC. 
     
     
         15 . The system of  claim 11 , further including a collection bag coupled to the aspiration catheter.
