  • Patent number: 10681257
    Abstract: A system and method for determining a dimension of a target. The method includes: determining a camera parameter, the camera parameter including at least one of a focal length, a yaw angle, a roll angle, a pitch angle, or a height of one or more cameras; acquiring a first image and a second image of an target captured by the one or more cameras; generating a first corrected image and a second corrected image by correcting the first image and the second image; determining a parallax between a pixel in the first corrected image and a corresponding pixel in the second corrected image; determining an outline of the target; and determining a dimension of the target based at least in part on the camera parameter, the parallax, and the outline of the target.

  • Patent number: 10265200
    Abstract: The present embodiments provide an endoluminal prosthesis, such as a stent-graft, having a relatively low delivery profile. In one embodiment, the prosthesis comprises a membrane, and at least one stent having contracted and expanded states, where the stent is coupled to the membrane and maintains patency in the expanded state. The prosthesis further may comprise selectively oriented axial and/or circumferential fibers arranged at predetermined locations along the length and circumference of the prosthesis. An increased population density of the circumferential and/or axial fibers may be provided in areas in which the at least one stent portion is attached to the membrane, or in areas of higher physiological loads imposed upon the endoluminal prosthesis.

  • Patent number: 9895217
    Abstract: The technology described herein relates to a stent graft and a method of making the stent wherein the stent comprises interconnected struts and is connected to the graft material by applying at least one band of polymer so as to cover at least a portion of at least some of the struts. A stent supported area is created by the stent's attachment to the graft material and the at least one band of polymer is applied so as to leave the majority of the stent supported area uncovered by the at least one band of polymer.

  • Patent number: 9788933
    Abstract: An aortic stent-graft may include a tubular graft extending from a proximal end to a distal end, the graft comprising a proximal sealing portion and an intermediate portion, wherein a proximal end of the intermediate portion abuts the distal end of the proximal sealing portion. At least one sealing stent may be attached to the proximal sealing portion. A first fenestration window is disposed in the intermediate portion. The first fenestration window has a length determined by the equation L=1.23*D?24 millimeters, where L is the length of the first fenestration window. D is between about 24 millimeters and 45 millimeters.

  • Patent number: 9155611
    Abstract: A stent graft (10) has a tubular body of a biocompatible material and a side arm (20) fastened to the tubular body. A tubular extension piece (24) is sealingly joined to the end of the side arm and extends from it. It can be joined with adhesive or stitching. The extension piece can be formed from an elastomeric biocompatible material such as Thoralon™. The extension piece can have a resilient reinforcement 44 embedded into it and extending longitudinally. The extension piece is tucked back into the side arm during deployment of the stent graft into a body lumen.

  • Publication number: 20100256736
    Abstract: A balloon expandable covered stent consists of a plurality of primary stent units, each having an undulating shape defined by a series of primary strut members converging to form peaks and valleys. The primary stent units are assembled into a single cylindrical structure of the stent by connecting corresponding peaks with secondary strut members. Generally, surfaces of the stent may then coated with a polymeric, hyper-elastic material, preferably Thoralon®, by pre-expanding the stent prior to coating.

  • Patent number: 7655033
    Abstract: A variable curvature stent limb is disclosed herein. A stent derived from a plurality of these variable curvature stent limbs may be highly compressible, such that it is compatible with a low-profile delivery device. This stent may be useful over a wider range of body vessel diameters and may possess a greater fatigue life, since this stent may provide a more controlled constant radial force.
