  • Devices and methods for delivery of aortic and mitral valve prostheses
    Patent number: 8540767
    Abstract: Valve prostheses and implantation devices, and methods for use are provided. The devices may be used for transcatheter delivery of an aortic valve prosthesis or transapical delivery of a mitral valve prosthesis. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis, reducing the extent of imaging needed during the implantation procedure.

  • Valve prosthesis with movably attached claspers with apex
    Patent number: 8444689
    Abstract: A valve prosthesis, implantation device, and methods for use are provided. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis. Alternative designs of the devices allow different methods for minimally invasive implantation of a sutureless valve prosthesis, including transapical and transcatheter approaches. Also provided is a delivery device for delivery of a medical prosthesis though minimally invasive means.

  • Methods and devices for transapical delivery of a sutureless valve prosthesis
    Patent number: 8366767
    Abstract: A method for delivering a sutureless cardiac valve prosthesis using a transapical approach is provided. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis within the native cardiac valve, minimizing the extent of imaging necessary.
