Patents Assigned to MicroVention, Inc.
  • Publication number: 20250143715
    Abstract: A system for delivering an implant within a patient is disclosed. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting a notable change in resistance in the circuit supplying the heater coil with electricity. A core wire terminates prior to the distal end of the device, allowing for greater flexibility.

  • Publication number: 20250082337
    Abstract: An implant delivery system having an implant-pusher junction that has improved flexibility due to a shortened heater and tapered marker band. The heater capsule includes a coil having a complex shape made possible through additive manufacturing. The complex shape generates increased heat over a shorter length when compared to traditional linear coils. The marker band includes a tapered end that allows the implant to pivot relative to the pusher.

  • Patent number: 12226102
    Abstract: Devices for treating a cerebral aneurysm may include proximal and distal self-expanding resilient permeable shells each including a plurality of elongate resilient filaments having a braided structure. The distal permeable shell may include a first plurality of filaments gathered at least at the proximal end thereof. The proximal permeable shell may include a second plurality of filaments are gathered at least at the proximal end thereof. The expanded state of the distal permeable shell may have a convex shape at the distal end of the distal permeable shell and the expanded state of the proximal permeable shell may have a generally convex shape at the proximal end of the proximal permeable shell. The expanded states of the distal and proximal permeable shells may also define a toroidal cavity through which an elongate support member extends.
