  • Patent number: 11439506
    Abstract: Prosthetic mitral valves described herein can be deployed using a transcatheter mitral valve delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native mitral valve. This document describes prosthetic heart valve designs that interface with native mitral valve structures to create a fluid seal, thereby minimizing mitral regurgitation and paravalvular leaks. This document also describes prosthetic heart valve designs and techniques to manage blood flow through the left ventricular outflow tract. In addition, this document describes prosthetic heart valve designs and techniques that reduce the risk of interference between the prosthetic valves and chordae tendineae.

  • Publication number: 20220226105
    Abstract: A method of delivering a valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The method including collapsing a prosthetic valve having an expandable frame comprising a proximal end and a distal end and a longitudinal axis extending therethrough inside of a delivery instrument, such that a plurality of spaced anchors extending from the distal end of the expandable frame towards the proximal end are collapsed to an inverted position in a collapsed anchor configuration. The method further including advancing the delivery instrument a first distance such that the plurality of spaced anchors extend below the valve annulus, and releasing each of the plurality of spaced anchors such that each of the plurality of spaced anchors is repositioned from the inverted position to an expanded anchor configuration to contact a subannular location.

  • Publication number: 20220202567
    Abstract: A valve prosthesis to be deployed within a native heart valve at a native heart valve annulus. The valve prosthesis including an expandable frame and a plurality of spaced anchors. The expandable frame includes a proximal end and a distal end and a longitudinal axis extending therethrough. The expandable frame collapses radially for delivery and expands radially upon deployment to an expanded configuration. The plurality of spaced anchors extend from the distal end of the frame towards the proximal end, each anchor formed with a free end, and each anchor being expandable from a collapsed anchor configuration to an expanded anchor configuration, wherein each of the anchors includes a foot angle of from 0 to 45 degrees relative to the longitudinal axis.

  • Patent number: 10952757
    Abstract: Systems for less invasive medical procedures comprise a filter device mounted on an integrated guiding structure and an aspiration catheter. These components can be used together or separately, and the system can be used with other medical devices that are designed for less invasive procedures, such as procedures in a patient's vasculature. The catheter can have a radiopaque band that is held in place under metal wire embedded within the polymer forming the tube of the catheter. In some embodiments, the aspiration catheter has a small diameter distal portion that can access into small diameter vessels in which the distal portion has a smaller average diameter than the remaining tube of the catheter.

  • Patent number: 10682217
    Abstract: Filtration systems with integrated filter element(s) forming portions of the wall of the filtration catheter are disclosed. The filtration catheters disclosed herein are designed to be used alone or in conjunction with another filter device to provide embolic protection of both carotid arteries. Occlusive element such as balloon is placed on the exterior of the filtration catheter to redirect blood flow in the vessels during the filtration process as well as to help anchor the filtration catheter inside the vessel. The integrated filter element(s) does not require collapsing thus significantly reduces the complexity of the filtration system retrieval process and the chances of releasing emboli back into the blood stream. The compact design of the filtration systems makes them particularly suitable for embolic protection during endovascular procedures on or close to the heart.
