20130189648 | DEVICE AND METHOD FOR REMOVING DENTAL POSTS - A dental post removal device having a hollow tubular structure having a sidewall and two open ends, and engaging features formed on the sidewall, and a fixing structure formed on the hollow tubular structure adapted for pulling the hollow tubular structure. The engaging features can be a series of openings formed through the sidewall of the hollow tubular structure, and/or the inner wall surfaces of the sidewall that at least one of is scored, textured, dimpled, and/or coated with a high adhesion material. The engaging features being adapted to improve adhesion to a composite resin, cement and/or adhesives to be placed in the hollow tubular structure. | 07-25-2013 |
20140241819 | Safety Head Bur - A safety head bur with a working end with cutting and/or grinding head, a shaft, and a transition zone, which safety head bur provides enhanced safety when used. The cutting and/or grinding head is adapted to cut and/or grind, and has a rearmost diameter. A shaft is attached to the working end. A transition zone extends rearwardly from the rearmost diameter of the working end to a smaller diameter where the transition zone meets the shaft. | 08-28-2014 |

20080243002 | Electrostatically driven image probe - The present invention provides an imaging probe for imaging mammalian tissues and structures using high resolution imaging, including ultrasound and optical coherence tomography. The imaging probe uses electrostatic discharge for actuating a metalized cantilever which holds the end portion of imaging assembly which emits energy in the imaging probe device by holding the cantilever at a potential such that it is neither grounded or charged such that the only electrical path to ground is through a dissipative polymer forming part of the device which is enveloped by a wire or coil held at ground potential. A high voltage electrode attracts the metalized cantilever and the dissipative polymer is used to connect to the cantilever to ground causing the cantilever to move about thereby scanning the region in front of the probe. | 10-02-2008 |
20090264768 | Scanning mechanisms for imaging probe - The present invention provides scanning mechanisms for imaging probes using for imaging mammalian tissues and structures using high resolution imaging, including high frequency ultrasound and/or optical coherence tomography. The imaging probes include adjustable rotational drive mechanism for imparting rotational motion to an imaging assembly containing either optical or ultrasound transducers which emit energy into the surrounding area. The imaging assembly includes a scanning mechanism having including a movable member configured to deliver the energy beam along a path out of said elongate hollow shaft at a variable angle with respect to said longitudinal axis to give forward and side viewing capability of the imaging assembly. The movable member is mounted in such a way that the variable angle is a function of the angular velocity of the imaging assembly. | 10-22-2009 |
