How effective is the Wells Johnson HVP system for fat transfer to the breast and minimizing damage from liposuction? (photo)

While there are other aspirators out there now, the Wells Johnson systems are the first real dedicated liposuction aspirators and generally recognized as the best.  They are probably the most widely used too.  All aspirators do is create a negative pressure, or suction, and with regard the cells, it's not the fat cells we necessarily need to preserve, but all the others that create most of the results we see.  The highest (or lowest really) negative pressure that any standard aspirator (one without special amplifying components) can create is one atmosphere, or about - 29 inches of mercury.  At this level of suction, the outside pressure of the air equalizes and prevents the vacuum from "sucking" any harder.  Thus, aspirators are limited, and most hope to hit this high of a level; suboptimal ones don't.  The higher the suction force, the more efficient the fat removal will be.  One of the major factors in damage to tissues during lipoharvest is actually the design of the cannula, not the suction power.  I usually want the most suction power I can achieve, but I want my cannula design - size, number, configuration and design of holes, etc. to be correct.  Thus, the short answer to your question, is "yes," the Wells Johnson machine is excellent for lipoharvest, and if your surgeon is proposing to use that, it is good.  The main question to ask is what about all of the other devices and techniques will he use?
