PROSTHETIC HEART VALVES
Some embodiments described herein include a heart valve replacement system that may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, a prosthetic heart valve of the system includes structural features that securely anchor the prosthetic heart valve to the site of the native heart valve. Such structural features can provide robust migration resistance. In particular implementations, the prosthetic heart valves occupy a smaller delivery profile, thereby facilitating a smaller delivery catheter for advancement to the heart.
PROSTHETIC LEAFLET DEVICE
A heart valve repair device, comprising an atrial-fixation member having an expandable mesh configured to have oval or circular shape in a deployed configuration, the atrial-fixation member defining a central lumen; and a baffle extending from a portion of the atrial-fixation member, the baffle having an anterior portion with a smooth, atraumatic surface configured to coapt with at least a portion of one or more native leaflets of a native heart valve, a posterior portion configured to engage and displace at least a portion of another native leaflet of the native heart valve, wherein the baffle extends radially inward from the atrial-fixation member into the central lumen to approximate a closed position of the displaced native leaflet.
Embolic protection device
The present invention includes an embolic protection device comprising a catheter having a self-expanding embolic filter that is disposed around the catheter proximal to a distal portion, wherein the embolic filter comprises a frame, and the frame defines an opening of the embolic filter that faces the distal end of the catheter; a deployment mechanism that is disposed around at least a portion of the catheter, wherein the deployment mechanism is longitudinally movable with respect to the catheter, the deployment mechanism is configured to contain the embolic filter in a collapsed configuration, and the embolic filter is configured to self-expand upon the longitudinal retraction of the deployment mechanism; and a wire coupled to the frame for expanding the size or diameter of the embolic filter opening.
UNCAGING STENT
A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provide high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold is typically formed from non-degradable material and will be modified to expand and/or uncage after deployment.
TRANSCATHETER AND SERIALLY-EXPANDABLE ARTIFICIAL HEART VALVE
Some embodiments are directed to a transcatheter and serially-expandable artificial heart valve, e.g., to be minimally-invasively implanted into a pediatric patient during a first procedure, and then expanded during a second procedure to accommodate for the pediatric patient's growth. Some embodiments include an expandable frame having a compressed, delivery configuration, and an expanded, deployed configuration, in which the valve is implantable within the patient. The valve can have a first working condition when the frame is expanded to a first diameter and a second working condition when the frame is expanded to a second diameter greater than the first diameter. The valve can include a plurality of leaflets configured to accommodate the expansion of the frame and growth of the patient.
HEART VALVE SEALING DEVICES AND DELIVERY DEVICES THEREFOR
An device for treating a native valve includes a sealing element and an anchoring element. The sealing element is made from a braided mesh material. The sealing element is dimensioned to be deployed in an annulus of a native valve of a heart at a position between native valve leaflets to contact the native valve leaflets during ventricular systole to create a seal to prevent regurgitation of blood from the left ventricle to the left atrium. The sealing element is configured to both be radially expanded and radially reduced while at the position between the native valve leaflets. The anchoring element is adapted for deployment in the heart, the anchoring element coupled to the sealing element and configured to support the sealing element at the desired position between native valve leaflets.
STRUCTURES AND METHODS FOR TEAR SHAPING FOR REFRACTIVE CORRECTION
A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.
Prosthetic heart valve devices and associated systems and methods
Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an expandable support having an outer surface and configured for placement between leaflets of the native valve. The device can also include a plurality of asymmetrically arranged arms coupled to the expandable support and configured to receive the leaflets of the native valve between the arms and the outer surface. In some embodiments, the arms can include tip portions for engaging a subannular surface of the native valve.
FORCE TRANSDUCTING INFLATABLE IMPLANT SYSTEM INCLUDING A DUAL FORCE ANNULAR TRANSDUCTION IMPLANT
An implant system for restoring and improving physiological intracardiac vortical flow in a human heart is provided including a dual force transducting annular implant comprising laterally extending struts transitioning into annular structural members for positioning on the atrial side of the valve annulus; an anchoring system comprising a therapeutic base plate assembly attachable to the apex of the heart; and a tether assembly comprising a tether connected between the implant and the therapeutic base plate assembly.
Collapsible inner flow control component for side-delivered transcatheter heart valve prosthesis
The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular a side delivered transcatheter prosthetic heart valve having a collapsible inner flow control component, and an outer annular support frame having compressible wire cells that facilitate folding flat along the z-axis and compressing the valve vertically along the y-axis, or orthogonally to the central axis of the flow control component, allowing a very large diameter valve to be delivered and deployed to the tricuspid valve from the inferior vena cava or superior vena cava, or trans-atrially to the mitral valve, the valve having a height of about 5-60 mm and a diameter of about 25-80 mm, without requiring an oversized diameter catheter and without requiring delivery and deployment from a catheter at an acute angle of approach.
