  • Patent number: 12029863
    Abstract: The embodiments presented herein relate to concepts designed to eliminate the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature. In an example embodiment, a microcatheter with an enlarged distal section is described. The enlarged portion of the microcatheter may be located close to the inner diameter of the guide catheter in order to reduce any open space between the microcatheter and the guide catheter, and the guidewire can be placed through the microcatheter and used to guide the system. The microcatheter can include one or more marker bands to aid in aligning the microcatheter correctly relative to the guide catheter. After the guide catheter and microcatheter are tracked to the appropriate treatment site, the microcatheter can then be used to deploy various medical devices to treat a patient.

  • Publication number: 20240197335
    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: 20240091491
    Abstract: The present invention relates to an inner support catheter comprising an elongated catheter body with a distal region having a constrained linear shape and an unconstrained shape. The distal region includes a distal first section and a proximal second section that forms a major curve with the proximal second section in the unconstrained shape. In the unconstrained shape, the proximal second section lies substantially in a first reference plane, while the distal first section is positioned at least partially outside of the first reference plane. This configuration may allow for improved maneuverability and flexibility of the inner support catheter during medical procedures.

  • 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.
