  • Implant delivery system
    Patent number: 11857196
    Abstract: A system and method of delivering and detaching an implant within a body of a patient is described. A tether connects an implant with a delivery device. The delivery device includes a heater coil through which the tether passes. The inner diameter of the heater coil is about the same size or slightly larger than the outer diameter of the tether, allowing the tether to more efficiently break the tether during delivery.

  • Stent Delivery System And Method
    Publication number: 20230329888
    Abstract: A stent, a stent delivery system, and a method of delivering a stent are described that allow the porosity of the stent to be changed dynamically during a delivery procedure. Unlike prior stents and procedures that are configured to deploy with a predetermined porosity, the physician can create a region of high stent porosity over certain vessel features, a low stent porosity over other vessel features, and can create these porosity changes with at least one stent or stent layer.
