Publication number: 20230346535Abstract: Aspects described herein are directed to methods of evaluating an embolic filter. A method for evaluating an embolic filter includes positioning the embolic filter in a blood vessel. A measured quantity of radiopaque particulates is injected into the blood vessel upstream of the embolic filter. An efficacy of the embolic filter is determined via invitro imaging of the embolic filter and the radiopaque particulates.Type: ApplicationFiled: May 1, 2023Publication date: November 2, 2023Applicant: EmStop, Inc.Inventors: Taylor Wisgerhof, David Feddema, Mark Groh

Publication number: 20230069136Abstract: Embolic material capture catheters and related devices and methods constrain a distal end portion of an embolic material capture element in an insertion configuration. A method of deploying an embolic material capture element in a blood vessel includes constraining a distal end portion of the embolic material capture element in an insertion configuration via engagement with a dilator assembly. The embolic material capture element, in the insertion configuration, is advanced through the blood vessel. A deployment cap of the dilator assembly is distally advanced relative to a dilator sheath of the dilator assembly to release the distal end portion of the embolic material capture element from engagement with the dilator assembly to reconfigure the embolic material capture element from the insertion configuration to a fully deployed configuration via self-expansion of the embolic material capture element.Type: ApplicationFiled: September 20, 2022Publication date: March 2, 2023Applicant: EmStop Inc.Inventors: Mark Groh, Cinnamon Buckels Larson, Yen Liao

Publication number: 20220160506Abstract: An embolic material blocking catheter includes a handle assembly, an elongated element having a lumen, and a deployable embolic material blocking element. The embolic material blocking catheter is configured to accommodate insertion of a treatment catheter into the lumen to position a treatment device distal to the embolic material blocking element for administering a treatment at a treatment site and/or convey embolic material blocked by the embolic material blocking element for extraction from the patient.Type: ApplicationFiled: November 1, 2021Publication date: May 26, 2022Applicant: EmStop Inc.Inventor: Mark Groh

Patent number: 4664218Abstract: A safety back-up system for a vehicle automatically applies the brakes to stop the vehicle against reverse movement when the vehicle begins moving backward without an attendant at the rear of the vehicle. The system senses reverse motion of the vehicle, whether rolling backward down an incline or driven backward by the engine and automatically applies the brakes, unless the automatic braking is disabled by application of a manual input by an attendant positioned near the rear of the vehicle with a handheld signal transmitter. A manual override device is available to the vehicle's driver, enabling the driver to override the automatic braking device from inside the vehicle when necessary. A record may be kept in a computer memory of all uses of the manual override, to assure that the system is not defeated.Type: GrantFiled: October 5, 1984Date of Patent: May 12, 1987Assignee: National Emstop, Inc.Inventors: George A.
