Description

DEVICE AND SYSTEM FOR GENERATING AN ACOUSTIC ENERGY WAVEFORM HAVING SHOCKWAVE BURSTS FIELD OF THE INVENTIONThe present invention relates to a device and system that generate an acoustic energy waveform and in particular a ballistic collision device and system configurable to generate an acoustic energy waveform having shockwave bursts.

BACKGROUND OF THE INVENTIONAcoustic energy in its various forms has varied uses in the medical industry including both diagnostic and therapeutic applications. Acoustic energy may come in the form of ultrasound, shockwaves, or radial waves, that have been put to extensive use in medicine. For example, medical imagery in the form of ultrasound is a commonly used form of acoustic energy. A therapeutic form of acoustic energy is also found in shockwaves used for example for triggering angiogenesis, osteogenesis, wound healing, lithotripsy kidney stone fragmentation, and the like.A shockwave is a form of acoustic energy resulting from a phenomenon that creates a substantially instantaneous intense change in pressure, for example as seen following an explosion or lightning. The intense change in pressure produces strong energy waves that can travel through various mediums such as gases, liquid, solids, air, water, human soft tissue, bone, metals, and the like. The waveform or signal of the shockwave pulse is characterized by a single positive peak followed by low negative peak, for example as shown in FIG. 4A. Such a shockwave pressure waveform and/or signal is adept at treating a single localize focal area and/or zone.

SUMMARY OF THE INVENTIONState of the art shockwave generating devices utilize various methods and system to generate a shockwave waveform and/or signal. For example, electrohydraulic, spark-gap, piezoelectric, ballistic, and electromagnetic, are all different types of systems that may be equally utilized to generate a shockwave signal, an example of which is shown in FIG. 4A. However, irrespective of the method utilized to generate the shockwave waveform, an individual (single) shockwave generating event correlates to a single shockwave pressure waveform and/or signal. Therefore current systems and method for generating shockwaves are based on a one to one ratio between a generating and/or triggering event to the number of shockwave pulses formed in the treatment area.Accordingly, so as to generate therapeutic levels of acoustic energy in the form of shockwaves at a targeted tissue site, state of the art shockwave generating device(s), must utilized many shockwave generating events to generate many shockwave signals in a one to one ratio. One generating event for each individual therapeutic shockwave signal.Therefore, while state of the art shockwave treatment devices are capable of selectively targeting tissue sites and controlling the energy levels that are delivered to the specific site, however, each individual shockwave generating event can only produce a single shockwave treatment signal. Accordingly, state of the art shockwave treatment devices function in a one to one ratio such that one shockwave generating event, irrespective of the technology that is used to generate the shockwave, leads to a single and/or individual therapeutic shockwave treatment signal. For example, state of the art ballistic shockwave devices generate a single shockwave waveform, single peak, from a single ballistic collision. The single shockwave is furthermore limited in terms of its therapeutic contribution, in that the size and depth of the tissue being treated is limited, an example of which is shown in FIG. 4B.Moreover, due to the one to one relationship discussed above, state of the art shockwave systems are limited in the area and depth of tissue that may be treated. That is, state of the art systems are inherently limited to treating small focal zones, and in particular for treatment zones that are disposed at a distance from the treatment surface, namely skin.Despite its current uses acoustic energy applications remain limited in terms of delivering sufficient acoustic energy at variable and/or extended tissue depths and in particular to treatment sites that have a large area. State of the art devices require many shockwave generating events to generate the corresponding amount of therapeutic shockwave signals.Furthermore, current acoustic energy devices are limited in that they cannot provide a shockwave energy waveform and/or signal that balances the delivered energy level and the corresponding tissue penetration depth and/or area. Specifically, a persistent problem in the art is the lack of fine control of the amount of acoustic energy that is made available at increasing tissue penetration depths and increasing treatment area.Accordingly with current state of the art shockwave treatment devices, in order to cover large tissue depth and area, a large amount of shockwave generating events are required to work in concert and over an extended time frame. This is due to the fact that each shockwave generating events results in a single shockwave for a single focal zone having a limited treatment area. Accordingly, the one event to one signal to one focal zone ratio provided by state of the art devices and system is not capable of producing a shockwave energy waveform that is capable to treat a treatment area that is both deep and wide (large area at increasing depth) in an efficient manner or over an efficient period of time.State of the art medical acoustic energy systems are additionally limited in fine control of the levels of acoustic energy available at increasing tissue depths. Such that control of the therapeutic acoustic energy level at increasing depths is currently not readily possible with state-of-the-art devices, due to the one to one relationship described above. To overcome this problem with existing state of the art acoustic energy systems, one would need to simultaneously change, the energy level, location of the applicator of the waves, use multiple applicators and/or change their shape.Current systems can only reach increased tissue depth by utilizing a large amount of energy and therefore can only deliver a large amount of acoustic energy at increased tissue depths. Such systems do not allow to fine tune and/or control the amount of acoustic energy delivered at deep tissue or over a large treatment area, particularly when the required energy density needed is narrow banded. Therefore, state of the art device provides an all or nothing approach for providing shockwave therapy at increasing tissue depths. However, some therapeutic uses of acoustic energy require low energy amounts at increased tissue depths and/or area. State of the art acoustic energy systems do not provide such low energy availability at increased tissue depth and/or area.There is an unmet need for, and it would be highly useful to have, a device and system for generating controllable acoustic energy waveform that can deliver controllable amount of acoustic energy to tissue at variable tissue depths and/or treatment area.

Accordingly, when utilizing at least one or more ballistic impact parameter ratios according to the present invention, a single ballistic collision provides for generating and propagating an acoustic energy waveform having at least two or more shockwave bursts (pressure peaks, FIG. 4C,4D).

The shockwave (SW) is generated by spark gap technology and is reflected toward the treatment site that is at an increased tissue depth , as shown with the arrow.

As can be seen the radial shockwave system 10r is capable of producing a single shockwave (SW) from a single SW generating event. FIG. 4B shows the shockwave (SW) waveform that is produced with the system depicted in FIG. 3B. The SW is characterized in that it has a long lifespan of about 1000 microseconds and having a low pressure peak that is spread over the signal’s extended lifespan.Therefore, each of the state of the art systems, FIG. 3A, 4A and FIG. 3B, 4B are limited in at least one of SW tissue penetration depth and size or the peak pressure available at the targeted tissue site.The device 150 and system 100 according to embodiments of the present invention, FIG. 3C and FIG. 4C, overcome these deficiencies of the state of the art SW devices.FIG. 3C shows a schematic illustration of previously described system 1and shows that a single ballistic event, between projectile 152 and anvil 156, generates a unique shockwave waveform 105 that is capable both of to treat tissue at increased depth and size, therein a large treatment site may be produced, and furthermore produces, at least two or more and more preferably multiple shockwave bursts, that individually feature high pressure peaks and a total lifespan of up to about 250 microseconds. Accordingly, the shockwave waveforms 1according to embodiments of the present invention, shown schematically in FIG. 4C, is therefore adapted to treat a large tissue area at extended tissue depths from the surface of the skin. The shockwave waveform 105 is characterized in that a single shockwave generating events produces a plurality of shockwaves, that display sufficient energy in each burst to treat tissue at increased depths and areas. FIG. 4D shows an example of acoustic energy waveform 105 as achieved with the system 100 according to embodiments of the present invention. Waveform 1 comprises a plurality of shockwave burst 105a,105b,105c that are generated with a single triggering event 105i.
