    Abstract: In a vertical MOSFET, an inactive ion species is ion-implanted into a J-FET portion, a surface channel layer, and/or a base region. The inactive ion species fill intrinsic carbon vacancies or interact with interstitial Si atoms, which are possible origin or responsible for B-diffusion from the base region. Accordingly, the B-diffusion caused by the intrinsic carbon vacancies when the base region is formed is suppressed. The width of the J-FET portion is prevented from being decreased, thereby preventing an increase in resistance of the J-FET portion. Also, the conductive type of the surface channel layer is prevented from being inverted by diffused impurities.

    Abstract: The present invention relates generally to medical compositions, methods and devices/systems for treating vascular diseases. More particularly, the invention relates to medical methods, devices and kits for distributing drug to surrounding vascular tissue to treat neointimal growth. More specifically, the described invention is intended to overcome shortcomings of existing treatments for peripheral artery disease (PAD). Devices and methods of the present invention are specifically intended to treat patients with PAD involving the infrapopliteal (tibial) arteries, e.g., patients having a clinical indication for treatment below the knees (e.g., claudication and/or critical limb ischemia (CLI), and patients with complex disease states, for reducing one or more of morbidity; treatment complications in treated patient populations, a reduction in target lesion revascularization (TLR) rates; and a reduction in patients populations requiring any type of leg amputation.

    Abstract: A system and method for visualization of subsurface anatomy includes obtaining a first image from a first camera and a second image from a second camera or a second channel of the first camera, where the first and second images contain shared anatomical structures. The second camera and the second channel of the first camera are capable of imaging anatomy beneath the surface in ultra-violet, visual, or infra-red spectrum. A data processor is configured for computing registration of the first image to the second image to provide visualization of subsurface anatomy during surgical procedures. A visual interface displays the registered visualization of the first and second images. The system and method are particularly useful for imaging during minimally invasive surgery, such as robotic surgery.
