  • Publication number: 20160206322
    Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.

  • Patent number: 9089405
    Abstract: A complex coil configured such that in a relaxed, minimum energy state configuration loops are formed having various orientations relative to each other. The complex coil provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may be deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

  • Publication number: 20120245521
    Abstract: One embodiment of the present invention discloses a balloon catheter employing a reinforced, co-axial, duel lumen design. In certain embodiments, at least one of the lumens is formed of a multilayer, tubular element in which one of the layers functions, in part, to provide radial reinforcement to the tubular element.
