Abstract
Systems and methods for treating a blood clot include a catheter to be inserted into a patient. The catheter is used to deliver low stability microbubbles toward the blood clot in the patient. A thrombolytic agent is delivered toward the blood clot, and ultrasonic energy is applied to the microbubbles to vibrate the microbubbles.
Claims132
A method of treating a blood clot, said method comprising:
- inserting a catheter into a patient;
- delivering low stability microbubbles toward the blood clot in the patient;
- delivering a thrombolytic agent toward the blood clot;
- and
- applying ultrasonic energy to the microbubbles to vibrate the microbubbles.
2 more elements
A system for treating a blood clot, said system comprising:
- a catheter configured to be inserted into a patient;
- low stability microbubbles;
- said catheter configured to deliver said microbubbles toward the blood clot in the patient;
- and
- an ultrasonic energy device configured to apply ultrasonic energy to the microbubbles to vibrate the microbubbles.
2 more elements
A method of treating a blood clot, said method comprising:
- inserting a catheter into a patient;
- delivering low stability microbubbles toward the blood clot in the patient;
- measuring the diameters of the low stability microbubbles in real time;
- and
- changing the diameters of microbubbles produced by varying at least one of gas pressure and liquid flow rate input to a microfluidics device the produces the microbubbles.
2 more elements
A system for treating a blood clot, said system comprising:
- a catheter configured to be inserted into a patient;
- and
- a microfluidics device contained in a distal end portion of said catheter, said microfluidics device configured to produce low stability microbubbles, said microfluidics device comprising electrodes configured to operate as a micro Coulter device to measure changes in impedance as the low stability microbubbles flow past the electrodes.
