In an embodiment, a heart valve replacement system is included having a delivery catheter can include a heart valve accommodation region; and a heart valve disposed around the delivery catheter at the heart valve accommodation region of the delivery catheter, the heart valve can include a frame; and a plurality of valve leaflets coupled to the frame; wherein the valve leaflets include an animal tissue, the animal tissue can include from 15% to 50% by weight water; and from 20% to 70% by weight glycerol; a package defining an interior volume, wherein the delivery catheter and the heart valve are disposed within the package. Other embodiments are also included herein. | 2021-03-18 |
20210077254 | Collapsible Leaflets for Prosthetic Heart Valves - A prosthetic heart valve may include a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets attached to at least one of the cuff or the stent within an interior region of the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a flat mesh of braided wire material having a plurality of pores extending therethrough. The leaflets may be devoid of biological material at a time of implantation. | 2021-03-18 |
20210077255 | RAPID IMPLANT PROSTHETIC HEART VALVE SYSTEM - A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided. | 2021-03-18 |
