Patent number: 11980537Abstract: Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.Type: GrantFiled: August 22, 2023Date of Patent: May 14, 2024Assignee: Inari Medical, Inc.Inventors: Ben Merritt, Jacqueline Macias, Brian Michael Strauss, Thomas Tu, John Coleman Thress, Paul Lubock

Patent number: 8511509Abstract: Enclosure for storing sensitive materials are disclosed. They may be in a special container (1), sealed and purged, replacing the internal atmosphere with an inert purge gas, and leaving the sealed container slightly pressurized. By hinging a lid or door (5) to the container via hinges (12, 13), the respective parts of which can move relative to one another translationally, at least when the door or lid (1) is in the closed position, and in a direction perpendicular to the plane of the door or lid, much improved sealing may be achieved. The invention also relates to methods used to deliver and duct the purge gas within the container to ensure good purge gas delivery and mixing.Type: GrantFiled: April 16, 2008Date of Patent: August 20, 2013Assignee: Roylan Developments LimitedInventor: Paul Merritt

Patent number: 8234774Abstract: One embodiment of the present invention sets forth a method for decreasing a temperature coefficient of frequency (TCF) of a MEMS resonator. The method comprises lithographically defining slots in the MEMS resonator beams and filling the slots with oxide. By growing oxide within the slots, the amount of oxide growth on the outside surfaces of the MEMS resonator may be reduced. Furthermore, by situating the slots in the areas of large flexural stresses, the contribution of the embedded oxide to the overall TCF of the MEMS resonator is increased, and the total amount of oxide needed to decrease the overall TCF of the MEMS resonator to a particular target value is reduced. As a result, the TCF of the MEMS resonator may be reduced in a manner that is more effective relative to prior art approaches.Type: GrantFiled: December 21, 2007Date of Patent: August 7, 2012Assignee: SiTime CorporationInventors: Paul Merritt Hagelin, Charles Grosjean

Patent number: 7545237Abstract: One embodiment of the present invention sets forth a serrated tooth actuator for driving MEMS resonator structures. The actuator includes a fixed drive electrode having a serrated tooth surface opposing a MEMS resonator arm also having a serrated tooth surface, where the MEMS resonator arm is configured to rotate towards the drive electrode when an AC signal is applied to the drive electrode. Such a configuration permits higher amplitude signals to be applied to the drive electrode without the performance of the actuator being compromised by nonlinear effects. In addition, the serrated tooth configuration enables a sufficiently high actuating force to be maintained even though the distance traversed by the MEMS resonator arm during operation is quite small. Further, the serrated configuration allows a MEMS resonator system to withstand larger fluctuations in voltage and larger substrate stresses without experiencing a substantial shift in resonant frequency.Type: GrantFiled: December 20, 2006Date of Patent: June 9, 2009Assignee: SiTime Inc.Inventors: Paul Merritt Hagelin, David Raymond Pedersen

Patent number: 7443258Abstract: There are many inventions described and illustrated herein. In one aspect, the present inventions relate to oscillator systems which employ a plurality of microelectromechanical resonating structures, and methods to control and/or operate same. The oscillator systems are configured to provide and/or generate one or more output signals having a predetermined frequency over temperature, for example, (1) an output signal having a substantially stable frequency over a given/predetermined range of operating temperatures, (2) an output signal having a frequency that is dependent on the operating temperature from which the operating temperature may be determined (for example, an estimated operating temperature based on a empirical data and/or a mathematical relationship), and/or (3) an output signal that is relatively stable over a range of temperatures (for example, a predetermined operating temperature range) and is “shaped” to have a desired turn-over frequency.Type: GrantFiled: April 6, 2006Date of Patent: October 28, 2008Assignee: SiTime CorporationInventor: Paul Merritt Hagelin
