20130131655BREAST RECONSTRUCTION OR AUGMENTATION USING COMPUTER-MODELED DEPOSITION OF PROCESSED ADIPOSE TISSUE - A tissue transfer method for reconstruction and augmentation of soft tissue. The method includes harvesting adipose tissue from a patient. The harvested tissue is processed via centrifugation to isolate a purified subset of the adipose tissue including separating and removing a substantial amount of triglycerides from the harvested adipose tissue.

20100234832METHOD FOR VASCULAR TREATMENT - A method is disclosed for improved minimally invasive vascular treatment. The procedure consists in performing a femoral nerve block, in order to achieve a sensorial block but not a motor block in the lower extremity. A femoral nerve block carries low risk of complications and when combined with block of the sciatic nerve provides anesthesia of almost the entire lower extremity. In a preferred embodiment, 20 ml of about 0.1% to about 0.5% lidocaine are injected under echographic/ultrasound control. After the anesthesia takes effect, a needle or other means is inserted through the skin into the vein to be treated and an optical fiber is introduced inside it. In a preferred embodiment, optical fiber is a radial emitting fiber and wavelength used is 1470 nm. Laser radiation is emitted while withdrawing the optical fiber, choosing appropriate irradiation parameters for each case. Nerve block technique disclosed can be used for vascular treatment in general, particularly whenever local energy techniques are employed, whether they be laser, thermal or RF sources, and anywhere sensorial anesthesia is needed and it is desirable for the patient to retain motor control. This new vascular procedure facilitates physician tasks since it is a very simple method to perform. Real time ultrasound monitoring of vein closure process is feasible, allowing the surgeon to use the minimum amount of energy possible, thus minimizing damage to surrounding tissues. This, in turn, considerably diminishes possibility of human error and as a consequence enhances patient safety. Furthermore, patient comfort is enhanced due to an excellent analgesia, during and after the treatment.09-16-2010
