Abstract

A method and device producing extracorporeal shockwaves for the treatment of erectile dysfunction.

Claims

1. A method for the treatment of Erectile Dysfunction, the method comprising:

(a) associating a penis with a shockwave generating device within an aqueous environment using a penis treatment coupling assembly comprising;

a proximal opening and a treatment neck for accepting and retaining the penis for undergoing a shockwave treatment;

wherein the treatment neck extends from the proximal opening; and

wherein the treatment neck is aligned with the shockwave generating device; and

(b) applying a shockwave regimen to the penis wherein the shockwave generating device produces shockwaves that are directed at a focal zone comprising at least a portion of corpus cavernosa of the penis;

the shockwave generating device utilizing an electrohydraulic or an electromagnetic shockwave generating mechanism.

2. The method of claim 1 wherein the shockwaves are directed at a focal zone which includes most of the corpus cavernosa.

3. The method of claim 1 wherein the shockwaves are directed at a focal zone which comprises most of the length of the penis.

4. The method of claim 1 wherein the shockwave regimen promotes at least one or more therapies for treating symptoms of Erectile Dysfunction chosen from the group consisting of:

vasodilatation, vasoconstriction, angiogenesis, endothelial function, neuronal, neural regeneration, decalcification, increase cytoplasmic calcium concentration, reduce cytoplasmic calcium concentration, inhibition of PDE5, enzymatic inhibition, enzymatic excitation, or any combination thereof.

5. The method of claim 1 wherein the shock wave regimen is determined based on at least one parameter chosen from the group consisting of shockwave parameters, treatment protocol parameters, and anatomical parameters.

6. The method of claim 5 wherein the shockwave parameters comprise number of shockwaves, frequency of shockwaves and intensity of the shockwave.

7. The method of claim 6 wherein the parameters are selected from at least one of:

shockwave intensity in a range between 50 bar to 200 bar;

shockwave frequency in a range between 60 to 300 shockwaves per min; and

the number of shockwaves is below 3500 per session.

8. The method of claim 5 wherein the anatomical parameters comprise a selection of one or more treatment zones selected from at least seven treatment zones within the penis and corpus cavernosa.

9. The method of claim 5 wherein the anatomical parameters comprise a single focal zone including up to about 90% of the corpus cavernosa of the penis.

10. The method of claim 1 further comprising placing at least a portion of the corpus cavernosa of the penis in reduced pressure environment of about 0.1 to 0.8 atm.

11. The method of claim 10 wherein the reduced pressure environment is an aqueous environment provided for by a liquid chosen from the group consisting of water, oil, and gel.

12. The method of claim 11 further comprising administering the shock wave regimen in combination with a drug or medicament.

13. The method of claim 12 wherein the medicament or drug is chosen from a group consisting of stem cells, growth factors, hormones, peptides, biologics, DNA, RNA, animal extract, plant extract, oil, gel, balm, cream, angiogenic drugs, PDE5 and vasodilating drugs.

14. The method of claim 11 wherein at least one of the shockwaves targets at least one or more of the penis vasculature chosen from the group consisting of:

cavernosal artery, dorsal artery, bulbar artery, cavernosal vein, dorsal vein and bulbar vein.

15. The method of claim 11 wherein the shockwave treatment is applied at least during one phase of an erectile cycle chosen from the group consisting of initiation, generation, maintenance, and detumescence.

16. The method of claim 11 wherein at least one of the shockwaves is directed towards at least one or more penile anatomy chosen from the group consisting of corpora cavernosa, corpus spongiosum, and glans.

17. A shockwave treatment apparatus for the treatment of erectile dysfunction comprising:

(a) shockwave applicator comprising a shockwave generator adept for generating shockwaves utilizing an electrohydraulic or electromagnetic shockwave generating mechanism, the shockwave generator produces the shockwaves that are directed to a focal treatment zone comprising at least a portion of a corpus cavernosum of a penis;

wherein the focal treatment zone comprises dimensions of length and width, wherein the length of the focal treatment zone comprises most of the length of the penis and the width of the focal treatment zone comprises most of the width of the penis; and

(b) a penis treatment coupling assembly comprising a proximal opening and a treatment neck for accepting and retaining the penis for undergoing a shockwave treatment;

wherein the treatment neck extends from the proximal opening; and

wherein the treatment neck is aligned with the shockwave generator and wherein the treatment neck is configured to provide an aqueous environment along a length of the treatment neck.

18. The shockwave treatment apparatus of claim 17 wherein the penis treatment coupling assembly further comprises a distal opening for accepting the shockwave applicator.

19. The shockwave treatment apparatus of claim 17 wherein the penis treatment coupling assembly is provided in the form of a flexible extracorporeal shockwave therapy (‘

ESWT’

) cushion treatment head.

20. The shockwave treatment apparatus of claim 18 wherein the penis treatment coupling assembly is provided in the form of a flexible extracorporeal shockwave therapy (‘

ESWT’

) cushion treatment head that is coupled with the shockwave applicator, forming a continuous lumen containing an aqueous solution for propagating the generated shockwaves.

21. The shockwave treatment apparatus of claim 20 further comprising at least one vacuum inlet and outlet wherein the vacuum inlet and outlet provides for positioning the penis in a penis positioning treatment neck;

and wherein the vacuum inlet and outlet provide a vacuum strength of about 0.1 to 0.8 atm within the penis positioning treatment neck.

22. The shockwave treatment apparatus of claim 17 wherein the proximal opening comprises a seal for maintaining the aqueous environment.

23. The shockwave treatment apparatus of claim 22 wherein the seal provides for maintaining a contiguous aqueous environment along the length of the penis from about the glans to the bulbos.

24. The shockwave treatment apparatus of claim 17 wherein the penis treatment coupling assembly is disposable.

25. The shockwave treatment apparatus of claim 17 wherein the penis treatment coupling assembly is customized for multiuse.

26. The shockwave treatment apparatus of claim 17 wherein the shockwave applicator produces a shockwave based on at least one parameter chosen from the group consisting of shockwave parameters, number of shockwaves, frequency of shockwaves, intensity of shockwave, treatment protocol parameters, and anatomical parameters.
