Publication number: 20150025376Abstract: A liquid injector registers the data of a variable pattern in which an injection rate of a contrast medium varies with time. The injection rate of the contrast medium varies with time according to the variable pattern for maintaining a state in which the image contrast achieved by the contrast medium approximates an optimum level.Type: ApplicationFiled: October 3, 2014Publication date: January 22, 2015Inventors: Kazumasa Masuda, Atsushi Hatcho

Patent number: 8938285Abstract: A marker deployment tool may comprise a marker cannula having a lateral deployment aperture, a push rod slidably disposed within the marker cannula and a scalloped tip coupled to the distal end of the marker cannula. The scalloped tip may have a push rod recess configured to receive a portion of the distal end of the push rod such that the push rod does not appreciably extend out of the lateral deployment aperture when the push rod is actuated distally. The marker deployment tool may further comprise a magnet at or near the distal end. This magnet may be used in combination with a magnet or plurality of magnets disposed about an access chamber in a tissue sample holder to assist the user in aligning the marker deployment tool. The access chamber in the tissue sample holder may also include a valve, two valves, or a removable plug.Type: GrantFiled: August 8, 2011Date of Patent: January 20, 2015Assignee: Devicor Medical Products, Inc.Inventors: Kevin M. Fiebig, Jessica P. Leimbach, Kyle P. Moore, Morgan R. Hunter, Andrew P. Nock

Publication number: 20150011879Abstract: A method for using CO2 as a contrast material in medical imaging procedures is disclosed. The method includes providing a source of pressurized CO2. The step of providing includes connecting the source of pressurized CO2 to a compressed gas unit for controlling delivery of the CO2. The method also includes regulating pressure of the CO2 delivered by the compressed gas unit, transmitting the pressurized CO2 from the compressed gas unit to a control valve assembly for delivery to a patient in controlled dosages, and sequentially processing the CO2 with the control valve assembly and delivering the CO2 to the patient as a contrast media.Type: ApplicationFiled: September 26, 2014Publication date: January 8, 2015Inventors: Frank Levy, Kimberley Levy

Patent number: 8915399Abstract: A medical fluid injection system may include a powered injector and a fluid reservoir that contains a simulated contrast medium. The simulated contrast medium may exhibit a fluid flow property substantially equal to that of an active contrast medium but be devoid of any active contrast agent that provides contrast during diagnostic imaging. During operation, a syringe in the powered injector may be filled with the simulated contrast medium and then evacuated to discharge the simulated contrast medium from the syringe. The simulated contrast medium may be used to test and evaluate the performance of the powered injector prior to use in a medical procedure without exposing personnel to an active contrast agent or creating medical waste that contains the active contrast agent.Type: GrantFiled: November 6, 2012Date of Patent: December 23, 2014Assignee: ACIST Medical Systems, Inc.Inventor: Sidney D. Nystrom

Publication number: 20140371586Abstract: A medical device that may include an elongate member having a proximal end and a distal end, and a lumen disposed through the elongate member is disclosed. The medical device may also include an opening disposed at the distal end of the elongate member in communication with the lumen, and a pushing element disposed with the lumen. The medical device may also include at least one fiducial disposed within the lumen and distal to the pushing element, and a separating mechanism disposed at the distal end of the elongate member. The separating mechanism may be configured to apply a separating force to deploy the at least one fiducial.Type: ApplicationFiled: June 6, 2014Publication date: December 18, 2014Inventors: Shawn RYAN, Joseph A.

Patent number: 8895929Abstract: Improved analytical, diagnostic, monitoring, and other methods (and their associated devices) for evaluating the extent of deposition of an agent onto a substrate are described. Exemplary methods may be used in the in the monitoring of the dental health of patients or in the fast, efficient screening and/or characterization of formulations in terms of their use for depositing oral actives onto tooth surfaces. The methods involve the direct or in situ analysis of substrates, onto which agents are deposited, using Near-IR spectroscopy and/or UV spectroscopy.Type: GrantFiled: July 2, 2014Date of Patent: November 25, 2014Assignee: Colgate-Palmolive CompanyInventors: Jennifer Gronlund, Guofeng Xu, Deborah A.

Patent number: 8862207Abstract: A liquid injector (400) injects a medical liquid into a patient whose fluoroscopic image data is to be picked up and generates injection history data corresponding to the injection, and a control box (500) registers the injection history data in a RIS (100) in association with imaging order data. Accordingly, the RIS (100) also stores the injection history data associated with the imaging order data, and therefore the injection history data can also be confirmed based on the imaging order data.Type: GrantFiled: April 2, 2007Date of Patent: October 14, 2014Assignees: Resource One Inc, Nemoto Kyorindo Co., Ltd.Inventors: Masashi Goto, Shigeru Nemoto
