Abstract

An ultrasonication apparatus is provided for improving catheter function. The ultrasonication apparatus includes a transducer configured to produce ultrasonic waves for ultrasonication and a chamber for containing a fluid having a passage for receiving a catheter. The chamber is adapted to receive the ultrasonic waves from the transducer.

First claim

What is claimed:

1. An ultrasonication apparatus for improving catheter function comprising:
a transducer configured to produce ultrasonic waves; and
a chamber configured to contain at least one of a water based solution and a gel and adapted to receive the ultrasonic waves from the transducer, the chamber including a slot along a bottom of the chamber and,
a cover moveable from an open position to a closed position, the cover including a first opening, a second opening, and a submerging wall extending from the cover towards the bottom of the chamber,
wherein a passage is defined between the first opening and the second opening with the slot therebetween, the passage configured to receive a catheter therein extending between the first opening and the second opening, and wherein the submerging wall is configured to position the catheter within the slot as the cover moves from an open position to a closed condition;
wherein the ultrasonic waves are configured to eliminate at least one obstruction in the catheter.

2. The ultrasonication apparatus of claim 1 , wherein the ultrasonic waves have a frequency of approximately 40 kHz, or 60 kHz.

3. The ultrasonication apparatus of claim 1 , wherein the chamber is formed of a material that sound travels therethrough at 2000 m/s or greater.

4. The ultrasonication apparatus of claim 1 , wherein the chamber is formed of polycarbonate.

5. The ultrasonication apparatus of claim 1 , wherein the at least one obstruction in the catheter is one or more of bodily excrement and cellular products.

6. The ultrasonication apparatus of claim 1 , wherein the transducer employs a sweep function to modify the frequency of the ultrasonic waves.

7. The ultrasonication apparatus of claim 1 , wherein a fluid comprising at least one of a water based solution and a gel is disposed in the chamber, and wherein the fluid does not flow under room temperature and pressure.

8. The ultrasonication apparatus of claim 1 , wherein the apparatus is handheld.

9. The ultrasonication apparatus of claim 8 , further comprising a handle coupled to at least one of the transducer and the chamber.

10. The ultrasonication apparatus of claim 1 , wherein the apparatus is configured to be moved along contiguous segments of the catheter.

11. The ultrasonication apparatus of claim 1 , wherein the transducer is configured to pulse the ultrasonic waves.

12. The ultrasonication apparatus of claim 1 , wherein the transducer is configured to produce ultrasonic waves having a square waveform.
