  • Patent number: 10548611
    Abstract: In at least one embodiment, a medical device can comprise an elongate outer sheath that extends along a sheath longitudinal axis and defines a central lumen extending therethrough, the elongate outer sheath can comprise a proximal sheath portion and a distal sheath portion. A first guidewire can comprise a first guidewire end and a second guidewire end, the first guidewire can extend from the first and second guidewire ends through the central lumen and can form a distal looped portion. An occlusion device can be disposed at a distal end of an elongate flexible shaft. The elongate flexible shaft can extend from the proximal sheath portion through the central lumen. The occlusion device can include a guide lumen through which the first guide wire passes.

  • Patent number: 10370150
    Abstract: The invention provides a two-part package and method of use for a pre-attached medical implant and delivery tool system. The package includes a wet compartment and a dry compartment and allows a pre-attached implant and delivery tool system to be at least partially stored immersed in a fluid in the wet compartment and at least partially stored in the dry compartment. In one embodiment the implant comprises a replacement heart valve, and the heart valve is stored inside the wet compartment while the heart valve delivery tool remains dry in the dry compartment.

  • Patent number: 7824443
    Abstract: An apparatus for endovascularly replacing a patient's heart valve. In some embodiments, the apparatus includes a replacement heart valve implant comprising a valve and an expandable anchor; and a deployment tool adapted to endovascularly deliver the replacement heart valve implant to an implant site within the patient, the deployment tool comprising an actuator adapted to exert an axially directed force on the anchor. The invention also provides a method for endovascularly replacing a heart valve of a patient. In some embodiments, the method includes the steps of endovascularly delivering a replacement heart valve implant having a valve and an anchor to an implant site within the patient; and applying an axially directed force from an actuator outside of the patient to the anchor. In invention also provides deployment tools for performing the method.
