Abstract: 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.

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.

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.

Abstract: Embolic material capture catheters and related devices and methods employ a staged deployment of an embolic material capture element. A method of deploying an embolic material capture element in a blood vessel includes advancing the embolic material capture element in an insertion configuration through the blood vessel. A middle portion of the embolic material capture element is expanded via distal advancement of an inner sheath toward a distal end portion of the embolic material capture element constrained by a dilator assembly. The dilator assembly is then reconfigured to release the distal end portion of the embolic material capture element from engagement with the dilator assembly. Upon release, the distal end portion of the embolic material capture element expands to complete deployment of the embolic material capture element in the blood vessel.

Abstract: A device for delivering oxygenated blood and occluding the ascending aorta is provided. The device has a blood flow lumen with a movable portion. The movable portion is movable from a position contained within a body of the device to a position which extends outwardly from the device. The movable portion is made of a tube of flexible material and everts when moving to the extended position.
