    摘要: 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.

    摘要: A needleless or high-pressure injection system for injecting treatment or therapeutic fluid to tissue of the lower urinary tract, such as the prostate or bladder, is provided. The systems or devices can release the therapeutic fluid or “injectate” at high-pressure out of one or more orifices at the end of an elongate shaft inserted into the urethra. Various embodiments can include a pneumatic or fully-pneumatic system adapted to selectively release the high-pressure injectate, while also providing firing or triggering protection.

    摘要: Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.
