Growth Stent and Valve for Congenital Narrowings
A growth stent and valve and methods for making and using the same. The growth stent and valve may be delivered to treat early stage congenital lesions, while expanding to adult vessel diameters. In selected embodiments, the growth stent and valve can comprise a frame and may have a covering on some portion to prevent blood flow through a wall of the frame. The growth stent and valve advantageously can maintain radial strength across an entire range of diameters necessary to treat a narrowed lesion from birth and childhood through adulthood as the vessels grow over the lifetime of a patient.
Systems, devices, and methods for coupling a prosthetic implant to a fenestrated body
Devices, systems, and methods for implanting a patient-specific prosthesis at a treatment site in a patient are disclosed herein. In some embodiments, a patient-specific prosthesis includes a tubular graft and a coupling member. A fenestration can be disposed in the tubular graft, the fenestration corresponding to a predicted branch blood vessel location. The coupling member can be disposed about the fenestration. The coupling member can include a coil configured to expand from a first configuration to a second configuration in response to the application of an expanding force. The coil can be configured to contract to a third configuration upon removal of the expanding force.
Left Atrial Appendage Stasis Reduction
Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.
Myocyte-derived flow assist device: extravasal sheaths of rhythmically contracting myocytes aiding flow of biological fluids
This invention relates, e.g., to a Myocyte-based Flow Assist Device (MFAD) for treating a subject in need of increased flow of a biological fluid, such as venous blood or lymph, comprising a sheath which comprises rhythmically contracting myocytes.
DIVERSIFIED GRAFTS HAVING HETEROGENOUS FEATURES AND METHODS FOR MAKING AND USING SAME
Diversified grafts suitable for use in repair and reconstruction procedures are provided. Some diversified grafts comprise two or more heterogenous features which form regions having different preferred properties. A diversified graft useful for pre-pectoral breast reconstruction, meshing is provided on an upper pole of the diversified graft and a plurality of slits arranged in particular patterns is provided on a lower pole of the graft, whereby the upper pole has a greater expansion ability and the lower pole has lesser degree of expansion ability but maintains greater load bearing capacity which is necessary to support the lower pole of the breast undergoing reconstruction, while allowing for fluid egress. In other embodiments, the diversified graft comprises two or more components which are combined by attaching them to each other to form a larger graft of the required size. The components may be smaller pieces of the same material or different materials.
Device for use with body tissue sphincters
A medical device may include an implantable device for treating a body tissue structure. The implantable device may include a wire structure which may include a wave pattern. The wire structure may be elastic so as to provide a pressure around the body tissue structure such that the pressure may change with movement of the body tissue structure.
VENTRICULAR STABILITY ELEMENTS FOR SIDE-DELIVERABLE PROSTHETIC HEART VALVES AND METHODS OF DELIVERY
A side-deliverable prosthetic heart valve includes a valve frame defining an aperture that extends along a central axis and a flow control component mounted within the aperture and configured to permit selective blood flow therethrough. The prosthetic heart valve has a compressed configuration for side-delivery to a heart of a patient via a delivery catheter. The prosthetic heart valve is configured to transition to an expanded configuration when released from the delivery catheter for seating in a native annulus. The valve frame includes distal, proximal, and septal anchoring elements, each of which is insertable through the native annulus prior to seating the prosthetic heart valve therein. The septal anchoring element is configured to extend below the annulus and contact ventricular septal tissue to stabilize the prosthetic heart valve in the annulus when the prosthetic heart valve is seated in the annulus.
Hybrid heart valves
A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible to a limited degree for delivery and expandable post-implant to facilitate valve-in-valve (ViV) procedures. The hybrid heart valves eliminate earlier structural bands, which both reduces manufacturing time and facilitates ViV procedures.
Atrial pocket closures for prosthetic heart valves
A prosthetic heart valve can include an outer frame coupled to an inner frame such that the outer frame can be moved between a first position and a second position in which the outer frame is inverted relative to the inner frame. The inner frame and the outer frame define between them an annular space, and a pocket closure can bound the annular space to form a pocket in which thrombus can form and be retained. The pocket closure can include a stretchable pocket covering that can move from a first position in which the pocket covering has a first length when the outer frame is in the first position relative to the inner frame and a second position in which the pocket covering has a second length greater than the first length when the outer frame is in the second position relative to the inner frame.
Prosthetic mitral valve and delivery method
A valve prosthesis and methods for implanting the prosthesis are provided. The prosthesis generally includes a self-expanding frame and two or more engagement arms. A valve prosthesis is sutured to the self-expanding frame. Each engagement arm corresponds to a native mitral valve leaflet. At least one engagement arm immobilizes the native leaflets, and holds the native leaflets close to the main frame. The prosthetic mitral valve frame also includes two or more anchor attachment points. Each anchor attachment point is attached to one or more anchors that help attach the valve prosthesis to the heart.
