  • Publication number: 20260232332
    Abstract: An embolic protection device may include an inflatable embolic balloon with one or more embolic capture elements located at or around its outer surface. The balloon may be inflatable so as to move the one or more embolic capture elements near or against the wall of a vessel. Emboli, and particularly emboli that are relatively more diffuse, softer, more friable, contain more inflammatory cells, and/or may lack fibrous caps, are captured or stopped by the one or more embolic capture elements as blood passes through the one or more embolic capture elements.

  • Publication number: 20260232324
    Abstract: The present invention discloses an aneurysm treatment device comprising a stent portion and an aneurysm filling portion expanding from an outer side of the stent portion. The device provides a novel approach to treating aneurysms by combining the structural support of a stent with an expandable filling portion to effectively address the needs of patients with aneurysms. The unique design of the device allows for precise placement and expansion within the aneurysm, providing stability and support while promoting healing and recovery. The device offers a versatile and minimally invasive solution for the treatment of aneurysms, improving patient outcomes and reducing the risks associated with traditional treatment methods.

  • Patent number: 12702422
    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.
