Patent number: 12765986Abstract: 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: GrantFiled: May 1, 2023Date of Patent: October 20, 2026Assignee: EmStop Inc.Inventors: Taylor Wisgerhof, David Feddema, Mark Groh

Publication number: 20250302605Abstract: Embolic material capture catheters and related devices and methods constrain a distal end portion of an embolic material filter assembly in an insertion configuration. A method of deploying an embolic material filter assembly includes advancing the embolic material filter assembly in the insertion configuration through a blood vessel. Pull wires are retracted to release the distal end portion of the embolic material filter assembly to reconfigure the embolic material filter assembly to a deployed configuration via self-expansion of the embolic material filter assembly.Type: ApplicationFiled: May 2, 2023Publication date: October 2, 2025Applicant: EmStop Inc.Inventors: Brenden Buster, Taylor Wisgerhof, Zoey Slettehaugh, Jeremy Adair, Alex Gustafson, David Feddema

Publication number: 20250049567Abstract: 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: August 28, 2024Publication date: February 13, 2025Applicant: EmStop Inc.Inventor: 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
