Publication number: 20240197335Abstract: 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.Type: ApplicationFiled: March 4, 2024Publication date: June 20, 2024Applicant: MicroVention, Inc.Inventors: Matthew J. Fitz, Cathy Lei, Joseph Gulachenski, Maricruz Castaneda, Gary Currie
