  • Patent number: 10702355
    Abstract: Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.

  • Publication number: 20200146774
    Abstract: Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.

  • Patent number: 10617498
    Abstract: Apparatus and methods for endodontic treatment of teeth provide effective cleaning of organic material (such as pulp and diseased tissue) from the root canal system. In an embodiment, a compressor system generates high pressure liquid (e.g., water) that flows through an orifice to produce a high-velocity collimated jet of liquid. The high-velocity jet is directed toward a surface of a tooth, for example, an exposed dentinal surface, and impingement of the jet onto the surface generates an acoustic wave that propagates throughout the tooth. The acoustic wave effectively detaches organic material from dentinal surfaces and tubules. The detached organic material is flushed from the root canal system by the liquid jet and/or by additional irrigation.

  • Patent number: 10551635
    Abstract: A sclera or contact lens with an image of an eye that is fenestrated, or uniformly speckled with many sub-millimeter sized transparent regions or holes, is disclosed. The micro fenestrated contact lens can be worn on a strabismic, or misaligned, eye so that its image is aligned with the wearer's dominant eye. The fenestrations allow the wearer to see through the opaque or translucent image printed on the contact lens, thus allowing binocular vision even though his or her strabismic eye is covered.

  • Patent number: 10485702
    Abstract: Surgical methods and related medical devices for treating ocular disorders are disclosed. Some methods relate to delivering an implant within an eye, and involve providing an elongate guide device, such as, a flexible guide member or a guide wire. A distal end of the guide device can be advanced into an anterior chamber of an eye, or through at least a portion of a site of resistance along a physiologic outflow pathway of the eye, or from an anterior chamber of the eye to a location proximate a physiologic outflow pathway of the eye. The implant is advanced along the guide device toward the guide device distal end, and is positioned to conduct aqueous humor between the anterior chamber and the physiologic outflow pathway.

  • Patent number: 10285856
    Abstract: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.

  • Publication number: 20180256922
    Abstract: Systems and methods for targeting specific cell types by selective application of ultrasonic harmonic excitation at their resonance frequency (“oncotripsy”) are presented. The systems and methods result in the permeabilization, lysis, and/or death of targeted cell types by using ultrasonic harmonic excitations that have their frequency and pulse duration specifically tuned to disrupt the nuclear membrane of the targeted cells types by inducing a destructive vibrational response therein while leaving non-targeted cell types intact. Target cells may be neoplastic.
