  • Patent number: 10420637
    Abstract: Apparatus and methods for stenting are provided comprising a stent attached to a porous biocompatible material that is permeable to endothelial cell ingrowth, but impermeable to release of emboli of predetermined size. Preferred stent designs are provided, as well as preferred manufacturing techniques. Apparatus and methods are also provided for use at a vessel branching. Moreover, embodiments of the present invention may comprise a coating configured for localized delivery of therapeutic agents. Embodiments of the present invention are expected to provide enhanced embolic protection, improved force distribution, and improved recrossability, while reducing a risk of restenosis and thrombus formation.

  • Publication number: 20180126119
    Abstract: An intravascular delivery system includes a delivery sheath capable of transmitting a predetermined tension or compression force in a longitudinal direction while maintaining flexibility to navigate tortuous anatomy. A method of delivering a medical device includes inserting an intravascular device delivery system including a delivery sheath having a continuous spine into a bodily lumen. A distal longitudinal force is applied to the delivery sheath. The distal force is transmitted through the continuous spine and across one or more slit cuts of the delivery sheath. A proximal longitudinal force is applied to the delivery sheath. The proximal longitudinal force is transmitted through the continuous spine of the delivery sheath.

  • Publication number: 20180055636
    Abstract: A method of delivering a rigid intravascular device to a target location in a patient's heart includes positioning a distal tip of an elongated member of the intravascular device delivery system in a right atrium of a heart and moving the distal tip of the elongated member into a left atrium of the heart. The method includes advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a first longitudinal distance; deflecting at least a portion of the inner steerable catheter a first deflection amount; then advancing an inner steerable catheter of the elongated member longitudinally distally relative to an outer sleeve of the elongated member a second longitudinal distance; and then deflecting at least a portion of the inner steerable catheter a second deflection amount.
