  • 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: 9060820
    Abstract: A segmented bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a segmented fixation device into an intramedullary space of the bone to place at least a portion of the fixation device in a flexible state on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to change shape as it moves from a flexible state to a rigid state.

  • Patent number: 8961516
    Abstract: A straight intramedullary bone fracture fixation device is provided with an elongate body having a longitudinal axis for deployment in a long bone, such as a clavicle. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device on one side of the fracture and at least a portion of a hub on another side of the fracture, and engaging an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations and designs may be used in combination with other fixation device components.
