Rachael QUINN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240033082
    Abstract: The present invention provides devices for treating functional mitral regurgitation and methods of use thereof. The devices translocate a subject's mitral valve in an apical direction. The devices thereby treat mitral regurgitation while preserving a subject's original mitral valve and chordae tendinae.

  • Patent number: 11523808
    Abstract: The present invention provides transseptal puncture devices configured to access structures on the left side of the heart from the right side of the heart without requiring open-heart surgery. The devices have adjustable stiffness to enter the vasculature in a flexible, atraumatic fashion, then become rigid once in place to provide a stable platform for penetration of the fossa ovalis. The devices are further configured to controllably and stably extend a needle to puncture the FO. The devices include an indwelling blunt stylus that can extend perpendicularly from the device to increase the accuracy of placement near the fossa ovalis.

  • Publication number: 20220249126
    Abstract: In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.
