Description
- The present invention relates to a system and a method to divide liposuction fat into aliquots for use and cryopreservation purposes.
- The fat removed by means of liposuction is known to be used in the ambit of surgical operations, e.g. for aesthetic and/or regenerative purposes.
- Currently, in such operations, the fat is used as soon as removed through the liposuction operation, because there is no way of effectively storing the fat in order to use it when needed, in subsequent times.
- This implies that only one part of the fat removed will be employed for the mentioned aesthetic/regenerative operations, while the rest remains unused, and is often disposed of, whereas regenerative operations are particularly effective if repeated over time, even at a distance of years.
- It results that, so far, these aesthetic/regenerative operations can be repeated over time only at the price of performing as many liposuction operations, which is not only extremely inefficient, but it is somehow also traumatic and invasive for the person who undergoes them.
- The main aim of the present invention is to provide a system and a method that enable to divide liposuction fat into aliquots, so it can be cryopreserved in order to use it over time for operations of aesthetic and regenerative type.
- Within this aim, one object of the invention is to provide a system and a method to divide liposuction fat into aliquots, which process the fat in a bacteriologically isolated manner.
- Another object of the present invention is to provide a system and a method to divide liposuction fat into aliquots which allow to overcome the mentioned drawbacks of the prior art in the ambit of a simple, rational, easy and effective to use as well as affordable solution.
- The above mentioned objects are achieved by the present system for dividing liposuction fat into aliquots for use and cryopreservation purposes made in accordance with claim 1.
- The above mentioned objects are achieved also by the present method to divide liposuction fat into aliquots for use and cryopreservation purposes implemented in accordance with claim 8.
- Other characteristics and advantages of the present invention will become better evident from the description of a preferred, but not exclusive embodiment of a system and a method to divide liposuction fat into aliquots, illustrated by way of an indicative, but not limitative example in the enclosed drawings, in which
FIG. 1 is a schematic representation of the system according to the invention. - With particular reference to such figures, globally indicated by reference numeral 1 is the system of the invention.
- The adipose material containing subcutaneous fat, which remains at the end of an operation of liposuction, is made available in suitable containers, which will hereinafter be referred to as taking
containers 12. - In the case of using the so-called “water jet” liposuction method, such material also comprises an aqueous fluid which is substantially formed by the water used in this method, in the form of a pressurized jet, to detach the fat from the surrounding tissues, preparing it for aspiration.
- The proposed system 1 comprises at least a
transfer circuit syringe pumping means transfer circuit container 12 and to transfer sealed said fat or said aqueous fluid within saidcircuit - The pumping means 2, 3 are available so as to separate by gravity, the fat from the aqueous fluids composing the adipose material contained in them.
- The system 1 also provides one or more rejection receptacles 5 connected sealed to the
circuit - Furthermore, the invention provides at least a cryopreservation container 6 (but preferably a plurality) to receive the fat in a sealing manner, which
cryopreservation container 6 is connected to thecircuit - This
cryopreservation container 6 can be made of a material resistant to a cryoprotective substance (such as in particular dimethyl sulfoxide), for reasons that will be explained hereinafter. - Preferably, the connection between the
cryopreservation container 6 and the circuit is of the releasable type. - The circuit also comprises first valve means 4 for allowing alternately the communication between the pumping means 2, 3 and the rejection receptacle 5 or between the pumping means and the cryopreservation container 6 (or containers).
- The proposed system 1 may further comprise at least one
access 7, 8 for the injection of the cryoprotective substance, which access is able to be put in communication with the inside of thecryopreservation container 6. - It should be noticed that the system 1 described above is bacteriologically isolated, since it is able to preserve and process the adipose material (or its components), without this coming into contact with the external environment, thus ensuring the highest level of sterility in particular to the fat that has to be used again for the aforementioned aesthetic and/or reconstructive operations.
- Hereinafter, the operation of the invention is illustrated in detail, together with its preferred and not limiting aspects of construction.
- As shown in
FIG. 1 , the aforementioned pumping means preferably comprise: apumping syringe 2 and second valve means 3 (e.g. comprising one or more two- or three-way cocks) able to put in sealed communication, alternately, thesyringe 2 with the takingcontainer 12 or thesyringe 2 with the first valve means 4. - In particular, the second valve means 3 may be connected sealed to an inlet channel 9 having, at the free end thereof, a needle for the introduction of said adipose material.
- As said, the adipose material is made available in the taking containers and is preferably “enriched” with mesenchymal cells, especially if the aliquots of fat obtained with the proposed system 1 are to be used in operations of the regenerative type.
- The presence of mesenchymal cells is the reason why the invention may provide for the use of the cryoprotective substance and, consequently, of components made of a material resistant to this substance.
- In fact, the cryoprotective substance is used to prevent, when the aliquots of fat undergo a significant lowering of temperature, the mesenchymal cells from being damaged by the formation of crystals within the fat itself.
- The second valve means 3 are operated so as to be arranged in the configuration wherein they enable the communication between the
syringe 2 and the container of adipose material (with the possible interposition of the inlet channel 9). - At this point, the
syringe 2 is operated to aspirate inside the adipose material. - Then, the adipose material is left within the
syringe 2, which is preferably arranged vertical so that, by virtue of the difference in specific weight between fat and water, the latter deposits at the bottom of its containment barrel, at the so-called “beak”. - This operation to be completed can take from fifteen to thirty minutes.
- As shown in
FIG. 1 , the above mentioned first valve means 4 preferably comprise a ramp of three-way cocks, each individually connected either to the rejection receptacle 5 or to at least a respective cryopreservation container 6 (in the example shown the cocks are five in number). - At this point, the first and second valve means 3, 4 are arranged in a respective configuration wherein they only allow communication between the
syringe 2 and the rejection receptacle 5, where the water separated from the fat is transferred, as a result of the suitable operation of thesyringe 2 itself. - It should be noticed that the rejection receptacle 5 can be connected sealed to the second valve means through a
rejection channel 11, included in the circuit. - Once filled with the water to be disposed of, the rejection receptacle 5, which can also be a common drip bag, is removed and replaced.
- Then, the second valve means 3 change again their configuration to enable the communication between the
syringe 2 and the ramp 4 of three-way cocks, the latter being in turn in a configuration that allows the communication between the cock of the second valve means 3 and thecryopreservation containers 6, while it prevents communication with the rejection receptacle 5. - At this point, the fat contained in the
syringe 2, and separated from water, is transferred within thecryopreservation containers 6, to define as many aliquots of fat, usable for the already mentioned operations. - To explain the next operation stage, it is convenient first to describe two devices of the invention which are not necessarily alternative to one another.
- According to a first embodiment, the mentioned access for the injection of the cryoprotective substance can be obtained at the outer periphery of each
cryopreservation container 6, in which case it is substantially an inlet 8 which can be perforated by the needle of a syringe for injecting the cryoprotective substance, which preferably comprises, or consists of, dimethyl sulfoxide (DMSO). - In the present description, by the term “cryopreservation container” is meant the container in its entirety, and not only the walls that define the inner containment volume (and therefore are included access tangs, ports, etc . . . ).
- In addition or as an alternative to this embodiment, an
inlet 7 which may be perforated for the injection of dimethyl sulfoxide (or other substance) can be arranged at a further free end of said inlet channel 9, which therefore has a forked configuration as in the representation ofFIG. 1 , and in practice the second valve means 3 are connected to an access 7 (which may or may not be single) and are configured so as to also allow the sealed communication between theaccess 7 and the first valve means 4. - In the latter case, not only the channel 9, but also the
entire circuit - Therefore, in practice, in the first embodiment, the DMSO is injected into each
container 6, so as to come into contact with the relative aliquot of fat, in order to protect it when the container itself will be stored in a refrigerator (and this is why, as mentioned in a previous paragraph, eachcontainer 6 is made of a DMSO-resistant material). - If instead there is a
single inlet 7, or any way saidinlet 7 is provided at the end of the inlet channel 9, then the user will inject insuch inlet 7 the DMSO, which, through thecircuit single container 6, in order to identify the respective aliquot of fat, able to be refrigerated without damage. - In this manner, instead, each
cryopreservation container 6 has internally, completely protected, an aliquot of fat which can be stored in the refrigerator, to define a sort of liposuction fat bank, from which each aliquot can be taken and used when needed, thus overcoming all the drawbacks of prior art. - Preferably, each of these
containers 6 is connected to the respective cock of the ramp 4 through arelative outlet channel 10, included in the circuit of the invention. - With the purpose of insulating the aliquot of fat contained in the
respective container 6 and separating the latter from the rest of the system 1, thisoutlet channel 10 is sealed by the user at a given point of its length and then cut according to procedures widely known to the skilled person. - In this way, each
container 6 is made individually and can be put into the refrigerator. - According to a possible aspect of the embodiment, each
cryopreservation container 6 has, at one of its peripheral walls, a breakable port, in communication with its interior, which can be substantially a closed tang that, following its breaking, allows the outflow of the aliquot of fat for the execution of the operation. - In an alternative embodiment, not shown in the illustrations, the
container 6 may be the type of a syringe device connected in a releasable manner to the first valve means 4 and able, alternately, to contain sealed or to inject fat for the infiltrations. More particularly, this syringe device comprises a receptacle (such as a drip bag) connected in a sealing manner with an infiltration syringe (e.g. through a channel and a single-acting valve incorporated to the syringe itself), to define, as a result of their filling with fat, a portable unit to contain (in isolation), and to inject an aliquot of fat. - After the taking
container 12 has been emptied, it is separated from the aforementioned inlet channel 9, at the branch of the aforementioned bifurcation, e.g. through the common practice of sealing and cutting off. - The proposed system 1 is devised to implement the method of the invention, which comprises the stages listed below:
- providing a taking
container 12 that contains adipose material removed by means of liposuction (and to which a predefined quantity of mesenchymal cells is preferably added);
taking a quantity of material from the container, keeping such material isolated from the external environment;
separating the fat from the aqueous fluids (which as said are substantially made of water) composing the adipose material of the taken quantity; and
transferring in a sealing manner the separated fat into one ormore cryopreservation containers 6, to define as many isolated aliquots of fat. - In a particular embodiment, the method includes the stage of adding a cryoprotective substance to each aliquot of fat, especially in the event of mesenchymal cells being added to the adipose material, for the reasons already explained when describing the system 1.
- In this case, the
cryopreservation containers 6 are made of a material resistant to a cryoprotective substance (preferably the aforementioned DMSO). - In a further stage of the method, each of said
cryopreservation containers 6, which substantially identify respective aliquots of portable fat, is placed in a refrigerator, where the fat is also kept for years without any deterioration. - In practice it has been found how the described invention achieves the intended objects by making available aliquots of liposuction fat, which can be cryopreserved and obtained through the use of a bacteriologically isolated system.
