Abstract

The system for treating an internal organ has a generator source for producing a shock wave connected to a portable shock wave applicator device, wherein the shock wave applicator device has a side-firing shock wave head having a variable angle adjustment relative to a release and lock connected handle or holder means for holding said device. The inclination of the shock wave head can be set to a fixed inclination to reach the organ at various locations or surfaces or can be pivotally inclined continuous to vary the treatment surfaces area.

Claims

1. A small portable hand-held electro-hydraulic shock wave applicator device comprising:

an applicator housing extending longitudinally;

a side firing shock wave applicator head at one end of the applicator housing;

a pair of electrodes with tips to create a shock wave generating spark to create the shock waves being used in medical applications having amplitudes above 0.1 MPa and rise times of the amplitude below 100 ns, the duration of a shock wave being below 1-3 micro-seconds (μ

s) for the positive part of a cycle and above a micro-second for the negative part of a cycle;

a reflector for redirecting and shaping a shock wave pattern transverse to a longitudinal axis of the shock wave device;

a membrane or lens covering said reflector for transmitting said shock wave pattern; and

wherein the pair of electrodes includes an inner electrode centered and held in an inner probe housing and at an opposite side of the applicator head is an outer electrode, the pair of electrodes being aligned and gapped at a distance S and being partially surrounded by the reflector wherein the shock waves are emitted from the applicator head in a sideways direction relative to the length of the applicator housing.

2. The shock wave applicator device of claim 1 wherein the reflector is a generalized paraboloid.

3. The shock wave applicator device of claim 1 wherein the reflector is a generalized paraboloid generating a very divergent wave emitted from the applicator.

4. The shock wave applicator device of claim 1 wherein the reflector is an ellipsoid.

5. The shock wave applicator device of claim 4 wherein the reflector is an ellipsoid having a focal point about 1-2 cm after the aperture.

6. The shock wave applicator device of claim 1 wherein the shock wave head further comprises:

a pivotable handle attached to the longitudinal housing for holding said device, the handle being pivotally inclined relative to the longitudinally extending housing of the device between 0° and

at least 180°

.

7. The shock wave applicator device of claim 1 wherein a space between said reflector and said membrane or lens defines a cavity, the two electrodes being located within said cavity.

8. The shock wave applicator device of claim 7 wherein the cavity is filled with a fluid medium.

9. The shock wave applicator device of claim 8 wherein said fluid medium is water under pressure.

10. The shock wave applicator device of claim 9 further comprises:

an inlet passageway and an outlet passageway in said reflector open to said cavity; and

an inlet fluid hose and an outlet fluid hose connected to said passageways for fluid delivery.

11. The shock wave applicator device of claim 7 wherein one of said electrodes is movably adjustable.

12. The shock wave applicator device of claim 7 wherein the device has the two electrodes with tips wherein the tips are fixed.

13. The method of employing a small portable hand-held shock wave applicator device comprises the steps of:

providing an at least partially exposed organ or direct access portal to an organ,

activating an acoustic shock wave generator or source to emit acoustic shock waves from a side firing applicator head with a pair of electrodes with tips to create a shock wave generating spark to create shock waves used in medical applications having amplitudes above 0.1 MPa and rise times of the amplitude below 100 ns, the duration of a shock wave being below 1-3 micro-seconds (μ

s) for the positive part of a cycle and above a micro-second for the negative part of a cycle, the shock wave emitted from a shock wave applicator head in a side firing pattern relative to the shock wave applicator device, a reflector for redirecting and shaping a shock wave pattern transverse to a longitudinal axis of the shock wave device;

a membrane or lens covering said reflector for transmitting said shock wave pattern; and

wherein the pair of electrodes includes an inner electrode centered and held in an inner probe housing and at an opposite side of the applicator head is an outer electrode, the pair of electrodes being aligned and gapped at a distance S and being partially surrounded by the reflector wherein the shock waves are emitted from the applicator head in a sideways direction relative to the length of the applicator housing; and

subjecting the organ to the acoustic shock waves stimulating said organ wherein the organ is positioned within an unobstructed path of the emitted shock waves, positioning the shock wave head adjacent to and on an inclination relative to the organ, and emitting a shock wave pattern in a generally transverse direction relative to the applicator head.

14. The method of claim 13 further comprises repositioning the shock wave head at a second position or inclination and generating a second shock wave emission.

15. The method of claim 14 includes the step of positioning the applicator by setting a holding means at an angle between 0°

and 360°

relative to the applicator head prior to emitting the shock waves, the holding means being a pivotable handle.

16. The method of claim 15 includes the step of positioning the applicator by setting the holding means at an angle between 0°

and 180°

relative to the applicator head prior to emitting the shock waves.

17. The method of claim 13 wherein the step of providing an at least partially exposed organ or direct access portal to an organ includes an open heart surgical procedure performed on a heart to be temporarily relieved of circulating function surgically open to inspection and shock wave treatment.

18. The method of claim 13 wherein the step of activating the shock wave generator or source to emit shock waves includes the step of controlling the emission of shock waves to be responsive to a repetitive body function.

19. The method of claim 18 wherein the step of controlling the emission of shock waves includes the step of using an ECG monitor to record the heartbeat pattern and QRS and T curve profile and triggering the emission of shock waves to the R portion of the curve representing the peak amplitude during a heart contraction.

20. The method of claim 19 further comprises the step of applying an acoustic coupling fluid medium onto the contacting surface of the membrane or lens cover of the device or the sleeve or both to couple the transmitted shock waves into the tissue or organ to be treated to couple the applicator with or without a sleeve covering to the tissue or organ.
