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.
Claims20
A method for implanting a prosthetic aortic valve in a patient having an aorta, the method comprising:
- supporting an embolic material blocking element in an insertion configuration via a distal portion of an embolic material blocking catheter;
- expanding the embolic material blocking element from the insertion configuration to a deployed configuration having an outer circumference interfaced with an inner surface of the aorta to substantially block flow of embolic material through the aorta past the embolic material blocking element;
- supporting the prosthetic aortic valve in a pre-deployed configuration via a distal portion of a delivery catheter;
- advancing the distal portion of the delivery catheter and the prosthetic valve in the pre-deployment configuration through a lumen of the embolic material blocking catheter to position the prosthetic valve in the aorta upstream of the embolic material blocking element in the deployed configuration;
- and
- reconfiguring the delivery catheter to deploy the prosthetic aortic valve upstream of the embolic material blocking element in the deployed configuration.

An embolic material blocking catheter, comprising:
- a handle assembly;
- an elongated element having a proximal portion coupled with the handle assembly, a distal portion, and a lumen extending through the distal portion;
- an embolic material blocking element coupled to the distal portion of the elongated element, the embolic material blocking catheter being reconfigurable from an insertion configuration to a deployed configuration, and from the deployed configuration to a captured configuration, the insertion configuration accommodating insertion of the distal portion of the elongated element and the embolic material blocking element into a blood vessel of a patient to position the embolic material blocking element downstream of a treatment site, the deployed configuration of the embolic material blocking element having an outer circumference adapted to interface with the inner surface of the blood vessel and substantially blocking flow of embolic material through the blood vessel past the embolic material blocking element, the captured configuration accommodating removal of the distal portion of the elongated element and the embolic material blocking element from the patient;
- and
- an insertion port configured to accommodate insertion of a distal portion of a treatment catheter into the lumen to position a treatment device mounted to a distal end of the treatment catheter distal to the embolic material blocking element in the deployed configuration for administering a treatment at the treatment site.

A system for implanting a prosthetic aortic valve into a patient having an aorta, the system comprising:
- an embolic material blocking catheter including:
- a handle assembly;
- an elongated element having a proximal portion coupled with the handle assembly, a distal portion, and a lumen extending through the distal portion;
- and
- an embolic material blocking element connected to the distal portion of the elongated element, the embolic material blocking catheter being reconfigurable from an insertion configuration to a deployed configuration, and from the deployed configuration to a captured configuration, the insertion configuration accommodating insertion of the distal portion of the elongated element and the embolic material blocking element into the aorta downstream of an implantation site for the prosthetic aortic valve, the embolic material blocking element extending proximally from the inner circumferential portion to an outer circumferential portion of the embolic material blocking element in the insertion configuration, the deployed configuration of the embolic material blocking element having an outer circumference adapted to interface with the inner surface of the aorta and substantially blocking flow of embolic material through the aorta past the embolic material blocking element, the captured configuration accommodating removal of the distal portion of the elongated element and the embolic material blocking element from the patient;
- and
- a delivery catheter configured to deploy the prosthetic aortic valve, the delivery catheter being configured to be advanced through the lumen of the elongated element of the embolic material blocking catheter to position the prosthetic aortic valve upstream of the embolic material blocking element for deployment, the delivery catheter including a deployment mechanism adapted to deploy the prosthetic aortic valve from a pre-deployment configuration.
