Publication number: 20200345487Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.Type: ApplicationFiled: July 20, 2020Publication date: November 5, 2020Applicant: Tendyne Holdings, Inc.Inventors: Mark Christianson, Zachary R.
