  • Patent number: 11918230
    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.

  • Publication number: 20230310006
    Abstract: The present invention provides for implant device delivery apparatuses and related methods of use. The delivery systems of the present invention incorporate a stretch resistant tube that advantageously makes the implant device, such as an embolic coil, stretch resistant while a delivery system is being used to position the implant device at a desired target site.
