  • Patent number: 11020208
    Abstract: Methods and devices are disclosed, by use of which an external fiducial element positioned in the mouth serves as a geometrical constraint on oral arch geometry. In some embodiments, the fiducial element is an oral insert which reaches to a plurality of oral arch regions to present surface details which are in well-defined distance and/or angular relationships to one another. These spatial relationships optionally comprise a spatial frame of reference which serves to constrain reconstruction of the geometry of one or both of the oral arches, for example reconstruction from a collection of digitally registered, partially-overlapping scans made along the oral arch.

  • Publication number: 20200155285
    Abstract: An intra oral scanner (IOS) including a probe is disclosed. Optionally, the probe is calibrated to measure locations at a higher accuracy than the IOS. For example, the probe may be used to locate points in a 3D map at high precision and/or the points used to increase the precision of location of other points and/or surfaces in the map. In some embodiments, the probe includes a sensor. Optionally, the probe may be used to measure locations that are hard to view with the IOS. For example, the IOS probe combination may be used to produce 3D maps of a recess in a tooth and/or gums and/or a periodontal pocket and/or to traduce a 3D map or periodontal disease. In some embodiments the probe may be used to measure physical properties, for example, the IOS probe combination may be used to produce a 3D image of hardness of mucosa.

  • Publication number: 20190262098
    Abstract: Methods and systems for tracking a dental tool within an oral cavity for taking and/or updating of a dental impression are described. In some embodiments, a marker, optionally a magnetic marker, is coupled to position movements of a rotatable dental tool. In some embodiments, detected movements of the marker are used, optionally in combination with other tracking data, to map contours which a portion of the rotatable dental tool follows during interaction with a dental surface. Optionally, the interaction occurs during grinding, drilling, and/or other procedures; which may be preparatory, for example, to the manufacture and/or fitting of a dental prosthetic.

  • Publication number: 20170007377
    Abstract: A method for measuring regions of a tooth in a mouth including: measuring at least one surface point on a surface of the tooth with respect to an element mechanically coupled to said surface point; determining a location of at least one visible reference mechanically coupled to said surface point with respect to said element; estimating a location of said surface point with respect to said visible reference. A device used for such measuring may include a main body comprising a final optical element of an imager which defines an optical field of view directed in a first direction; and a measurement element coupled to said main body extending generally in said first direction; where a tip of said measurement element is sized and shaped to be inserted between a tooth and adjacent gingiva; where said optical field of view is sized to image at least part of a tooth.

  • Publication number: 20120316638
    Abstract: In one embodiment, a delivery system for a medical device includes a flexible sheath defining a lumen having a distal end and a flexible shaft having a proximal portion and a distal portion. A retention element and a pushing element, spaced proximally from the retention element, are disposed on the distal portion. The flexible shaft, retention element, and pushing element are disposable within the lumen. The flexible shaft is movable distally through the lumen between a stowed position and a deployed position and is movable proximally through the lumen between the deployed position and a partially deployed position with the retention element proximate to the distal end of the lumen. The retention element is configured to form with the medical device an interference fit with the flexible sheath when the flexible shaft is urged proximally from the retention position to engage the medical device with the flexible sheath.

  • Publication number: 20080033341
    Abstract: A method of reducing or blocking blood to a selected blood vessel or a selected part of the wall thereof, particularly for treating an aneurysm, an arteriovenous or dural malformation in a blood vessel, or for devascularizing tumors, by deploying in the blood vessel an expandable member having a contracted condition for manipulation within the blood vessel, and expandable to an expanded condition in the blood vessel for reducing or blocking blood flow through the selected part thereof, thereby promoting coagulation of blood therein, and for preventing thrombus material from being swept downstream, and applying a local stimulus to the interior of the malformation effective to initiate or accelerate coagulation of blood therein. In some described embodiments, the expandable member is a permeable mesh-like tube of biocompatible material, and in other described embodiments, the expandable member is an inflatable balloon.
