  • Patent number: 9949364
    Abstract: Assembly methods and apparatus for electrically stable connectors are described herein where a conductive wire assembly generally comprises an insulative substrate having a length, one or more conductive elements formed along a first direction upon the substrate, an insulative coverlay formed upon the one or more conductive elements, and at least one opening or window defined through the insulative coverlay exposing a portion of the one or more conductive elements. A conductive coating is formed upon the insulative coverlay such that the conductive coating is in contact with the portion of the one or more conductive elements through the at least one opening or window and the conductive coating may have at least one region removed along a second direction in proximity to the at least one opening or window such that one or more conductive pads are formed and are electrically isolated from a remainder of the conductive coating.

  • Publication number: 20150245882
    Abstract: Systems for linear mapping of lumens are described which utilizes methods to create a linearized view of a lumen using multiple imaged frames. In reality a lumen has a trajectory in 3-D, but only a 2-D projected view is available for viewing. The linearized view unravels this 3-D trajectory thus creating a linearized map for every point on the lumen trajectory as seen on the 2-D display. In one mode of the invention, the trajectory is represented as a linearized display along 1 dimension. This linearized view is also combined with lumen measurement data and the result is displayed concurrently on a single image. In another mode of the invention, the position of a treatment device is displayed on the linearized map in real time. In a further extension of this mode, the profile of the lumen dimension is also displayed on this linearized map.

  • Publication number: 20140142398
    Abstract: Multifunctional guidewire assemblies and system for analyzing anatomical and functional parameters are described. Using a single guidewire assembly, functional and anatomical measurements and identification of lesions may be made. Functional measurements such as pressure may be obtained with a pressure sensor on the guidewire while anatomical measurements such as luminal dimensions may be obtained by utilizing an electrode assembly along the guidewire. The vascular network and stenosed lesions may be modeled into an equivalent electrical network and solved based on the measured parameters to obtain unknown parameters of the electrical network. Several treatment plan options may be constructed where each plan may correspond to the treatment of a subset of particular lesions. The anatomical outcome for each of the treatment plans may be estimated and the equivalent modified electrical parameters may be determined.
