SINGLE ACCESS FLOW-REVERSAL CATHETER DEVICES AND METHODS

摘要

Embodiments herein include devices and methods directed toward creating reverse flow within a vessel and thereby providing protection against embolic debris. Embodiments comprise a catheter and a plurality of occluders that are expandable and adjustable within a lumen to create low-pressure areas that reroute blood flow and embolic debris therein.

主权项

1. A method for providing embolic protection comprising the steps of providing a single access catheter device comprising:
a catheter having a proximal and distal region with a lumen therethrough; a first occluder located within the distal region of the catheter; a second occluder located proximal to the first occluder; a return port located proximal to the second occluder; and a conduit connecting the distal end of catheter to return port; locating a first occluder in a vessel proximate to a treatment site; locating a second occluder in an aorta downstream of a renal artery; expanding the first occluder and the second occluder whereby blood flows through the conduit from a distal end of the catheter to the return port.
