  • Patent number: 11660099
    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: 11123052
    Abstract: Forming a proximal anastomosis on an aortic wall includes method and instrumentation and apparatus for forming an aortic puncture and inserting into the vessel through the puncture a fluid-impervious sealing element with a protruding retainer. An anastomosis of a graft vessel over the puncture is partially completed with the retainer of the sealing element protruding through the partial anastomosis. The retainer facilitates removal of the sealing element from the partial anastomosis prior to completion of the procedure.

  • Publication number: 20200060817
    Abstract: A medical implant deployment tool and deployment method are disclosed. One aspect of the invention provides an implant system including an implant adapted for endovascular delivery and deployment; and a deployment tool adapted to deploy the implant, with the deployment tool having an actuation controller; a plurality of actuation elements adapted to apply forces to one or more implant deployment mechanisms and each adapted to extend along an actuation element path within a patient's vasculature; and an actuation element compensation mechanism adapted to compensate for differences in length between the actuation element paths.

  • 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.
