  • Intravascular treatment site access
    Patent number: 10682493
    Abstract: A device and its method of use eliminates or reduces the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature. The device is maintained at or near the distal end of the catheter while being advanced through the vessels of a patient. The reduced gap size prevents the catheter from otherwise “catching” on various structures of a vessel, such as a bifurcation.

  • Implant Delivery System
    Publication number: 20200178975
    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.

  • Liquid Embolic Delivery Device
    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.

  • Embolic Coil
    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.
