  • Patent number: 10034706
    Abstract: A control handle for a steerable catheter body for navigation of the catheter body through a biological lumen and manipulation at a treatment site. The control handle includes a housing assembly that houses a piston assembly and a resistance adjusting assembly. The resistance adjusting assembly can be adjusted to provide the desired frictional characteristics of the user for control of the resistance between the piston assembly and the housing assembly. In one embodiment, the piston assembly is configured to provide a frictional resistance that varies dynamically to substantially match the restorative force across the range of catheter tip deflection. Other embodiments include a vibrating member that provides tactile feedback to the operator to indicate conditions at the distal end of the catheter, such as contact force.

  • Patent number: 10022090
    Abstract: The present invention provides an energy based dissection device that automatically provides a nerve protection function. Specifically, the present invention operatively connects nerve monitoring technology and energy based dissection technology to provide a device that provides energy based dissection functionality that cannot operate, or operates differently, upon receipt of real time information from the nerve monitoring functionality that nerve damage may be imminent in the absence of such safety shutdown. The present invention also creates a real-time graphical display of the nerve, including size and location relative to the energy based dissection device to enable the operator to safely and accurately avoid damaging the nerve. Accordingly, the present invention provides a surgical device that removes human error and reaction time issues which prevent unintended dissection and concomitant nerve damage.

  • Patent number: 9936918
    Abstract: A method of providing a metal coating on a substrate (10), and electrically insulating sections/parts of the metal coated substrate from each other. A substrate is provided with an insulating material in the substrate, the insulating first material extending through the thickness of the substrate and protruding above one surface of the substrate. It forms an enclosed section/portion (14) of the substrate. A protective structure (15) is provided on the insulating material such that it covers the entire circumference thereof. The insulating material is selectively etched to create an under-etch (18) under the protective structure. Finally conductive material (19) is deposited to provide a metal coating over the substrate, whereby the under-etch will provide a disruption in the deposited metal coating, thereby electrically insulating the enclosed section from the surrounding substrate.
