Abstract: Various systems and methods of deploying an implant to a target location of a body vessel are disclosed. A delivery system can include a delivery tube and a pull tube, the pull tube at least partially disposed within a first lumen of the delivery tube. A link wire with two proximal ends can be welded to the pull tube and a distal end of the link wire can include a link wire loop. A pull wire can extend through the first lumen with a distal end positioned to secure the implant to the delivery system. The pull wire includes a proximal bend positioned around the link wire loop such that the proximal bend is positioned in a proximal direction relative to the distal end of the link wire loop by a slack length. The slack length is effective to prevent premature detachment of the implant from the delivery system.

Abstract: Delivery and detachment system for an implantable intravascular device, the system including a securement wire in a passageway of an inner support tube. Imposed on the securement wire is a controlled friction force established within an intentional friction zone created by: (i) reflow of an outer sleeve through side port opening(s) in the inner support tube and into the passageway; or (ii) the securement wire having bend(s) creating an associated point(s) of direct physical contact with the inner wall of the inner support tube. During delivery of the implantable intravascular treatment device to a target site, the imposed controlled friction force minimizing movement of the securement wire relative to the inner support tube, and upon reaching the target site, a force being applied to overcome the imparted controlled friction force and releasing the implantable intravascular device.

Abstract: A delivery member is provided for delivering and deploying an intravascular medical device. The delivery member includes a flexible distal portion including a wound wire coil surrounded by a flexible sleeve and inhibited from extending lengthwise by a support tube positioned through the lumen of the coil. The delivery member can include hypotubes positioned on either side (distally and proximally) from the wound wire coil to which the stretch resistant member and the wound wire coil can be attached. The distal hypotube can include attachment slots for positioning and attaching a loop wire to the distal hypotube. The distal hypotube can further include one or more tube windows for visualization of proper placement of the support tube within a lumen of the distal hypotube.
