DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) The following detailed embodiments presented herein are for illustrative purposes. That is, these detailed embodiments are intended to be exemplary of the present invention for the purposes of providing and aiding a person skilled in the pertinent art to readily understand how to make and use of the present invention.

(7) Accordingly, the detailed discussion herein of one or more embodiments is not intended, nor is to be construed, to limit the metes and bounds of the patent protection afforded the present invention, in which the scope of patent protection is intended to be defined by the claims and equivalents thereof. Therefore, embodiments not specifically addressed herein, such as adaptations, variations, modifications, and equivalent arrangements, should be and are considered to be implicitly disclosed by the illustrative embodiments and claims described herein and therefore fall within the scope of the present invention.

(8) Further, it should be understood that, although steps of various claimed methods may be shown and described as being in a sequence or temporal order, the steps of any such method are not limited to being carried out in any particular sequence or order, absent an indication otherwise. That is, the claimed method steps are considered capable of being carried out in any sequential combination or permutation order while still falling within the scope of the present invention.

(9) Additionally, it is important to note that each term used herein refers to that which a person skilled in the relevant art would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein, as understood by the person skilled in the relevant art based on the contextual use of such term, differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the person skilled in the relevant art should prevail.

(10) Furthermore, a person skilled in the art of reading claimed inventions should understand that “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. And that the term “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list.

(11) Referring now to the drawings in greater detail there is illustrated in FIG. 1, a first configuration 1 of instrument assisted soft tissue mobilization device, commonly referred to as a scraping tool or soft tissue mobilization device 10, which can be made from a hard material, such as stainless steel, titanium, various plastics, stone, animal bone, or an animal's antler or horn. A second configuration 2 is illustrated in FIG. 2. FIG. 1 and FIG. 2 illustrate the skin contacting member 12 of the soft tissue mobilization device 10 can be shaped into an appropriate configuration such that it had curves that were biologically appropriate, meaning that the soft tissue mobilization device 10 could have curvature that would allow it to slide over a part of a human body and apply force against the soft tissue under the skin (not shown). The shape of the soft tissue mobilization device 10 could be customized for application to a specific area of the body. For example, the shape of a soft tissue mobilization device 10 used on the hands would have much smaller curvature and would be lighter and easier for the practitioner to hold (FIG. 1) in comparison to a larger soft tissue mobilization device 10 with a larger curve (FIG. 2) which would be necessary for working on a larger portion of the body, such as, for example, the calves, thighs, or lower back (not shown).

(12) The soft tissue mobilization device 10 comprises a first end 14, a second end 16, a first side 18, a second side opposite said first side 20, and an edge extending along a periphery of said skin contacting member (“edge”) 22. The edge 22 can comprise at least one curve 24, though it could comprise a plurality of curves (not shown). The at least one curve 24 can comprise a small or a large arch, depending on what body part the soft tissue mobilization device is for. The edge 22 can also be straight or slightly curved (FIG. 2).

(13) FIG. 3 illustrates the method of coating the hand-held portion 26. The hand-held portion 26 can be dipped into a compound, preferably a polymer with a low melting temperature. The compound can also be a mixture of at least two components, such as at least two polymers with low melting temperatures or at least one polymer with a low melting temperature and at least one dye. The polymers can be selected from a group comprising thermoplastic, remodelable, and rubber. The compound is placed into container 30, warmed to a temperature above its respective melting temperature, and mixed. The hand-held portion 26 of the soft tissue mobilization device 10 can be dipped into the warm compound inside the container 30 to allow the compound to bond to the hand-held portion 26. The hand-held portion 26 is then extracted from the container and allowed to cool to a temperature that will not burn an ungloved hand. The compound semi-solidifies as it cools into the compressible material 28 (not shown).

(14) It could be preferable to create both a chemical bond between the materials, such as polymers, mixed to create the compressible material 28, as well as a mechanical bond between the compressible material 28 and the hand-held portion 26. For example, a stainless steel soft tissue mobilization device 10 would need to have a roughened surface created on the hand-held portion 26 to allow the compound, such as at least one polymer, to bond to the hand-held portion 26. The roughened surface could be created mechanically, for example, with sandpaper or a grinder, or roughened with an end mill, or laser, or possibly sandblasted in order to create more surface area for the compound to bond too. The increased surface area created by the roughening would allow for microbonding to occur between the hard material of the hand-held portion 26 and any suitable compound/compressible material bonded thereover.

(15) Also a mechanical bond between the two components of the hand-held portion 26 could be preferable. It is envisioned in one embodiment that the hard material of the hand-held portion 26 would include multiple openings therein (not shown) to allow a mixture of at least two materials, such as polymers or a polymer and a dye, to flow therethrough during the coating process and create a significant mechanical interface between the two materials in the hand-held portion 26. In a preferred embodiment, the compressible material 28 is made from one low melting point polymer 29. In one embodiment, the compressible material 28 is made from a mixture of at least two low melting point polymers.

(16) Also, it will be understood that using a low melting point polymer, the practitioner would be able to customize the handle directly to their hand, as an alternative to the method described above. By using a thermoplastic material to coat the hand-held portion 26, it would be possible to reheat and reshape as many times as is necessary to achieve a handle that is as comfortable as possible.

(17) In the manufacturing process of over-molding a compressible material 28, such as an ergonomic polymer, onto the material of the hand-held portion 26, there are several ways that this could be achieved which would be understood by one skilled in the art.

(18) Turning to FIG. 4, configuration 1 is shown and illustrates the custom molding of the compressible material to the shape of the practitioner's or user's hand(s) 32. The practitioner or user grabs the semi-solid cooled mixture of at least two polymers that has turned into the compressible material 28 with his or her hand(s) 23 to mold it to the shape of the practitioner's or user's hand(s) 32. The compressible material 28 does not adhere to the user's hand(s) 32 when it is grabbed by the practitioner or user.

(19) The compressible material 28 bonded to the hand-held portion 26 provides ergonomic support to the practitioner's or user's hand and decreases stress and/or strain on the hand(s) 32 when the practitioner or user uses the soft tissue mobilization device 10.

(20) Turning to FIG. 5, configuration 2 is shown and illustrates the custom molding of the compressible material to the shape of the practitioner's or user's hands using the same method as described for FIG. 4.

(21) In another configuration, the soft tissue mobilization device 10 or the skin contacting member 12 thereof would be similar, if not identical, to the ones described above. A practitioner could be provided with the core material body of the soft tissue mobilization device 10 and also receive two containers, each containing one part of a two-part mixture. The containers may contain rubberlike materials. The two parts of the rubberlike material would be mixed by the practitioner in an appropriate ratio which would provide a rubber or putty like material with a specific working time. This rubber material would then be hand molded by the practitioner over the hand-held portion 26 of the soft tissue mobilization device 10 to provide the most precise customized molded fit to the hand. The hand-held portion 26 could be roughened and/or possibly comprise holes, openings, grooves or undercuts in order to allow the mixture of the two parts to enter the hand-held portion 26 and easily bind the putty like material to the hand-held portion 26. The two part rubber or putty like material on the soft tissue mobilization device 10 would be allowed to harden for a specific amount of time, producing a customized ergonomic grip for the hand-held portion 26. An advantage to using a two-part rubber material is that the material would be soft and more pliable in the hand. This soft pliability of material would allow for better control and also the grip placed on the rubber-like material and would require less effort or forced use the tool on a patient.

(22) In another embodiment, the hand-held portion 26 of the soft tissue mobilization device 10 could comprise an over molded rubber or plastic pre-designed ergonomic grip. This would be achieved by using either a compression or injection mold and injecting thermoplastic or a setting type rubber around and possibly through the hand-held portion 26 of the soft tissue mobilization device 10. The advantage of this embodiment is that it would allow for high quantity production of a generically ergonomic handled soft tissue mobilization devices 10 that would be comfortable enough for use by a majority of practitioners.

(23) In another embodiment, an overmolded soft material such as a gel-like or squishy material would be molded over and possibly through the hard hand-held portion 26. The gel-like or squishy over molded material would provide a soft hand-held portion 26, and would conform to the user's hand(s) 32 as he or she was using it. One advantage of this embodiment is that the user does not need to choose a permanent design for the hand-held portion 26 and it would conform as needed to the user's varying demands.

(24) While certain exemplary embodiments of the device have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(25) Throughout this specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising” or the term “includes” or variations, thereof, or the term “having” or variations thereof will be understood to imply the inclusion of a stated element or integer or group of elements or integers but not the exclusion of any other element or integer or group of elements or integers. In this regard, in construing the claim scope, an embodiment where one or more features is added to any of the claims is to be regarded as within the scope of the invention given that the essential features of the invention as claimed are included in such an embodiment.

(26) Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. It is to be understood that the invention includes all such variations and modifications that fall within its spirit and scope. The invention also includes all of the steps, features, compositions and compounds referred to or indicated in this specification, individually or collectively, and any and all combinations of any two or more of said steps or features.

(27) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
