Abstract: An endovascular embolization system including a braided implantable device having: a tubular braid pre-formed as a default shape into multiple distinct sections including: an intermediate section interposed directly between a stabilizing section and a sealing section; the intermediate section having a stiffness greater than that of the stabilizing section; and a proximal section. Each of the stabilizing section and the sealing section are self-expanding between a radially expanded state when free from an externally applied radial force and a radially constricted state when subject to the externally applied radial force; each of the stabilizing section and the sealing section while in the radially expanded state have a maximum outer diameter larger than an outer diameter of each of the distal section, the intermediate section, and the proximal section.

Abstract: An endovascular embolization system including a braided implantable device having: a braided structure radially self-expanding and having a proximal edge; a proximal securement mechanism fixedly secured radially constraining a proximal section of the braided structure including the proximal edge; the proximal section of the braided structure defining an inner channel having an inner diameter smaller relative to an interior space disposed distally of the inner channel; a pushing member having a proximal end and a distal end; no portion of the pushing member being rotatable relative to another portion; and an unrestricted 360 degrees freely rotatable connection of the braided implantable device relative to the pushing member thereby preventing or minimizing longitudinal twisting of the braided implantable device during delivery through a microcatheter.

Abstract: Tubular braided implantable endovascular embolization device including a folded over tubular braid forming a folded over atraumatic distal surface and preformed into multiple distinct sections including: a stabilizing section; a sealing section; an intermediate section interposed between the sealing and stabilizing sections; and a proximal section. The stabilizing section and the sealing section are radially self-expanding to a maximum outer diameter larger than the intermediate section or the proximal section. Enhanced stiffness while obstructing open space regions maximizing disruption of blood flow therethrough is achieved by using a plurality of nested layers (at least one of which is the folded over tubular braid) to form the sealing section while the stabilizing section preferably formed by a single braided layer (i.e., the folded over tubular braid) optimizes compressibility and positioning.

The implant further includes an engagement member both movable within and confined within the braid section. The engagement member is attached to one or more of the proximal coil segment or the distal coil segment.

A detachment system can include a tubular body including a lumen extending therethrough and a distal tube on a distal end of the tubular body. A loop wire can be affixed at a first end to the tubular body and can include a loop opening positioned approximate a distal end of the distal tube. A pull wire can extend through the lumen. A hook wire can extend radially through a sidewall of the distal tube and into the lumen. The hook wire can be positioned around a pull wire portion and tensioned such that the pull wire portion abuts the distal tube and provides frictional resistance between the pull wire portion and the sidewall of the distal tube. The frictional resistance can be effective to inhibit premature detachment of the implant.

Abstract: An intravascular treatment system including an introducer sheath having an intentional friction zone along a section thereof imposing an intentional friction force on the outer surface of a catheter shaft slidable therein. The friction zone representing a non-straight (e.g., curved or bent) section of the introducer sheath and/or a section of the introducer sheath whose inner wall has a reduced inner diameter (e.g., fused heat shrink material). During intravascular treatment, sufficient axial force may be applied to overcome the imposed intentional friction force and advance the intravascular treatment device in a distal direction to a desired target site in the artery. Once properly positioned, the imposed intentional friction force ensures that the intravascular treatment device is maintained in place.
