  • Publication number: 20200146825
    Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. The implant is secured to tissue with anchors that can rotate without axial advancement to engage tissue while drawing the implant closer to the tissue. Collars are used to decrease the angle between struts of a frame to contract the implant. The implants can include a rotatable shaft, such as a threaded shaft, located internally to an axially translatable collar. Rotation of the shaft transmits force to the collar to cause the collar to translate axially, closing the angle of adjacent struts and decreasing the width of the implant and thus of the annulus. The implants can be delivered, secured and contracted via a catheter. The implants are repositionable and retrievable via catheter.

  • Publication number: 20200121461
    Abstract: Features for a restraint to facilitate delivery and deployment of an implantable cardiac device are described. The restraint may include a series of circumferential engagements for securing inwardly corresponding portions of the implant. The restraint may be located inside the implant and provide a radially inward force on the implant. The restraint may include a center shaft having a series of grooves configured to cooperate with corresponding splines of the implant. Distal or proximal advance of the restraint disengages the restraint from the implant. The implant may include a tubular frame configured to contract and be secured by the restraint in a contracted configuration and to expand upon disengagement from the restraint. The restraint may provide for a smaller overall cross-sectional profile of a transcatheter delivery system, for instance by negating the need for a distal delivery sheath.

  • Patent number: 9320597
    Abstract: A delivery system for percutaneously deploying a stented prosthetic heart valve. The system includes a delivery capsule and a recapture assembly. The capsule is configured to compressively retain the prosthesis. The recapture assembly includes a frame and sleeve attached to the frame. The recapture assembly is transitionable from a compressed arrangement to an expanded arrangement with a distally increasing diameter.
