  • Publication number: 20200155161
    Abstract: Embolic coils with detachable segments that are separated by detachment capsules that are thermolytically degradable such that varying lengths of coil may be implanted into a vascular malformation to occlude same. The capsules are radiotransparent when compared to the adjoining coil segments to the location of the segments is easily seen. The capsules further include protruding electrical contacts that make positive contact with terminals on a delivery catheter. The terminals on the delivery catheter serve as markers so the relationship between the detachment capsules and the terminals is easily visible under x-ray.

  • Publication number: 20200155800
    Abstract: Described herein is a liquid embolic delivery device designed to minimize excess embolic solvent buildup therein. The liquid embolic delivery device generally comprises an outer catheter, an inner catheter that is longitudinally moveable within the outer catheter. The inner catheter is used for an initial embolic solvent flush and to deliver liquid embolic, while the outer catheter is used to remove excess solvent.

  • Publication number: 20200093495
    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.
