  • Patent number: 8262591
    Abstract: This invention relates to a non-invasive, safer alternative to current lipoplasty procedures. The preferred embodiment of the invention is a multi-channel system that focuses the low mega Hertz ultrasound at user selectable depths, where fat cells are to be emulsified. The system offers independent user control of the main emulsifying property, cavitation, and thermal heating, which can independently be used for skin tightening. One part of the system is a handheld transducer, in shape similar to a typical small diagnostic ultrasound transducer. The other part of the system includes a transmitter with, for example, internal tracking of procedure time and with a disabling feature.

  • Patent number: 5941909
    Abstract: A new soft tissue implant filling material is disclosed. The surgically implantable soft tissue implant filling material has good aesthetic properties, as measured by viscosity and elasticity, and good elimination properties. One embodiment of such a new filling material is a gel which comprises three components. The first component is a water soluble polymer or hydrogel that has a high molecular weight. Alternatively, the first component is both crosslinked and has a high molecular weight. The second component of the filling material is a water-soluble polymer that is eliminated rapidly through the kidneys upon subcutaneous release. The third component of this filling material is saline, which is used to dissolve the polymer and to adjust the osmolality of the polymer. In addition, a buffer may be added to the filling material to adjust the pH of the gel. One gel formulation of the present invention, in its preferred embodiment, consists of polyacrylamide and derivatives thereof.

  • Patent number: 5159920
    Abstract: A scope and stent system, the scope providing visibility not only through the urethra but also through the ureter during the insertion and placement of a ureteral stent. The scope is in the form of a fiber optic bundle having an appropriate provision for lighting and lensing thereof, and preferably having a video camera and monitor responsive to the image formed at the opposite end of the scope for viewing during the scope insertion process. The fiber optic bundle itself is made sufficiently small so that the entire scope may be fabricated with the appropriate dimensions of a typical stent guide wire and made sufficiently flexible for negotiating a tortuous path as required.
