  • Publication number: 20250302605
    Abstract: 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.

  • Publication number: 20250049567
    Abstract: 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.

  • Publication number: 20230069136
    Abstract: 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.
