Harvesting Fat Tissue Using Tissue Liquefaction

Номер: US20130261606A1

Принадлежит: Andrew Technologies LLC

Target tissue may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the tissue to soften, liquefy, or gellify. The tissue that has been softened, liquefied, or gellified is then suctioned away. The matter that was suctioned away is collected and gravity separated, and fat that is suitable for implantation in the subject is extracted from a selected layer (e.g., the top half) of the supernatant of the gravity-separated matter. 1.

The object of providing a cerebrospinal fluid drainage system which reacts precisely to changes in pressure in the cerebrospinal fluid, with ease of operation, is achieved by the present invention in that a pump is used for draining the cerebrospinal fluid (liquor), wherein operating measured values supplied by sensors act as controlled variable for the operation of the pump. The pressure in the liquor line currently measured by a pressure sensor the liquor pressure in the intracranial cavity being treated, measured intracorporeally by a pressure sensor, and/or the volume of liquor already pumped out, as operating measured value, can, for example, serve as the basis for operational control of the pump of the liquor drainage system. The liquor drainage system according to the invention has the advantage that the liquor is drained not only simply on the basis of the excess pressure in the intracranial cavity being treated, but is actively pumped out of the intracranial cavity in a controlled manner, in particular with constant measurement of the liquor pressure. In this way the pumping capacity can be regulated depending on requirement and the drainage pressure or the liquor pressure kept reliably within a specific pressure range. 1. A drainage system for the drainage of cerebrospinal fluid (liquor) , with a liquor feed line and a pressure sensor , which determines the pressure in the liquor feed line , and/or a pressure sensor which determines the liquor pressure intracorporeally ,characterized in thatthe drainage system comprises a pump which pumps out the cerebrospinal fluid as a function of preset operating parameters and measured operating measured values.2.
