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.
Claims19
A method of filtering embolic material out of a flow of blood within a blood vessel of a patient's vasculature, the method comprising:
- advancing an embolic material blocking catheter within the patient's vasculature to position an embolic material filter of the embolic material blocking catheter for deployment within the blood vessel;
- reconfiguring the embolic material blocking catheter to deploy the embolic material filter from a collapsed insertion configuration to an expanded deployed configuration in which the embolic material filter is interfaced with the blood vessel;
- filtering embolic material out of the flow of blood within the blood vessel by the embolic material filter;
- operating an embolic material extraction device to remove embolic material filtered out of the flow of blood by the embolic material filter from the patient's vasculature through a lumen of the embolic material blocking catheter;
- reconfiguring the embolic material blocking catheter to reconfigure the embolic material filter from the expanded deployed configuration to a collapsed captured configuration;
- and
- removing the embolic material blocking catheter from the patient's vasculature via retraction through the patient's vasculature.
