Abstract: A stent including a hybrid network cluster of open cells and closed cells arranged wherein said closed cells are connected in a configuration to be resheathable. Open cells are not connected and the stent can be unsheathed to enhance flexibility. In one embodiment a ring of proximal closed cells are tapered and the stent is retrievable by engagement of a pushwire assembly.

Abstract: A stent delivery system comprising a balloon catheter having a catheter shaft with a balloon mounted on a distal end with a self-expanding stent positioned on the catheter shaft proximal to the balloon (tandemly) with a delivery sheath covering the self-expanding stent. In use, the stent delivery system is advanced on the guidewire to the target lesion and the balloon is inflated to dilate the lesion. The balloon is deflated and advanced distally past the lesion until the self-expanding stent positioned proximate the lesion. The sheath is withdrawn, releasing the self-expanding stent to expand and contact the lesion. Once the self-expanding stent has expanded, the stent delivery system and guidewire are withdrawn from the lesion.

Abstract: The present invention describes systems and methods using a detachment coupler mechanism of an implant assembly in delivering and detaching an implant at a target site or location within the neurovascular space/body of patient.

Abstract: A hypotube having a laser cut wave pattern to improve flexibility. The laser cut wave pattern on the hypotube includes multiple portions that vary the pitch and angle of the cuts. The laser cut wave pattern provides flexibility while maintaining pushability further into the most tortuous vasculature. The laser cut wave pattern also provides the ability to torque the flexible hypotube back and forth, with a 1 to 1 response, without stretching the flexible hypotube. The laser cut hypotube may be used in a number of vascular or neurovascular, such as a guidewire or catheter, or delivery of a stent.
