  • Publication number: 20230051186
    Abstract: A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. Alternatively, the device may include a rotating wire attached to the macerator element. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element.

  • Patent number: 10668208
    Abstract: Restenosis or neointimal formation may occur following angioplasty or other trauma to an artery such as by-pass surgery. This presents a major clinical problem which narrows the artery. The invention provides a balloon catheter with a particular electrode configuration. Also provided is a method whereby vascular cells in the area of the artery subjected to the trauma are subjected to irreversible electroporation which is a non-thermal, non-pharmaceutical method of applying electrical pulses to the cells so that substantially all of the cells in the area are ablated while leaving the structure of the vessel in place and substantially unharmed due to the non-thermal nature of the procedure.

  • Patent number: 10279112
    Abstract: Automated injection system disclosed in this application advantageously provides physicians with a simplified interface for selecting fluid sources, such as saline, contrast, or a mixture of both, to inject at high pressures. The injector system may comprise a multi-use subassembly, a single-use subassembly, a fitting to fluidly connect the multi-use and single-use subassemblies, a hand held controller, a user interface, and an injector housing.
