Abstract: Catheters are described that have improved flow characteristics that may be particularly helpful when delivering embolic agents within a blood vessel. One catheter includes a fluid flow modifier that is configured to create laminar fluid flow out of a distal end of the catheter to help reduce turbulence and achieve predictable fluid movement. Another catheter includes scavenging ports that are configured to suction in embolic agents that have refluxed proximally back from a distal end of the catheter.

Abstract: A delivery device may include a support structure for imparting a desired stiffness, springiness, and kink-resistance. The delivery device may include a core wire and/or one or more electrical wires which are electrically connected to a detachment mechanism. A medical device such as an implant may be attached to the delivery device by a detachment mechanism. A support structure may extend alongside or around the core wire to provide support for the delivery device, particularly when pushing a larger implant through a smaller catheter. The support structure may include a support wire alongside the core wire, a hypotube surrounding the core wire, a braid braided around the core wire, and/or a coil coiled around the core wire. The core wire may be formed from a non-memory-shape material such as stainless steel and the support structure may be formed from a memory-shape material such as Nitinol.
