  • IN-SITU FENESTRATION DEVICES WITH MAGNETIC LOCATORS AND HEATING ELEMENTS
    Publication number: 20240033027
    Abstract: An in-situ fenestration device for locating a fenestration site and for forming a fenestration. The in-situ fenestration device includes first and second magnetic locators configured to magnetically mate in a mated position within a vasculature of a patient at the fenestration site. The in-situ fenestration device also includes first and second heating elements configured to heat the first and second magnetic locators to form the fenestration at the fenestration site.

  • Transcatheter valve delivery systems and methods
    Patent number: 8414645
    Abstract: Delivery devices and methods for percutaneously delivering a prosthetic valve to the heart of a patient. These prosthetic valves may be configured to provide complimentary features that promote optimal placement of the prosthetic valve in a native heart valve, such as the aortic valve, mitral valve, pulmonic valve, and/or tricuspid valve. The delivery device includes a release sheath assembly housed within an outer delivery sheath. A release sheath component of the assembly captures a portion of the prosthetic valve to the delivery device, and effectuates complete release of the prosthetic valve with retraction of the outer sheath.
