Stents for prosthetic heart valves
A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stewed valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.
CLAMPS FOR COUPLING EXPANSION AND LOCKING ASSEMBLIES TO FRAMES OF PROSTHETIC VALVES
The present disclosure relates to implantable, mechanically expandable prosthetic devices, such as prosthetic heart valves, and to devices and methods for coupling expansion and locking assemblies to frames of such prosthetic devices.
SYSTEMS AND METHODS FOR MANUFACTURING A STENT FRAME
A prosthetic heart includes a support structure, an actuator member, a plurality of leaflets, and a sealing material. The support structure includes a plurality of struts movably coupled together such that the support structure moves incrementally between a radially compressed state and a radially expanded state. The struts include a plurality of commissure struts. The actuator member is coupled to the struts of the support structure and is configured to incrementally move the support structure between the radially compressed state and the radially expanded state and to automatically lock the support structure in a particular state. The leaflets are coupled to the commissure struts of the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve. The sealing material is coupled to the support structure and includes a plurality of commissure extensions that wrap around and are coupled to the commissure struts of the support structure.
Endovascular implants and devices and methods for accurate placement
Various systems, devices, and methods for endovascular implants and placement thereof are disclosed. The implants include a proximal implant segment, a distal implant segment, connector struts connecting the proximal implant segment to the distal implant segment, and a side opening between the proximal implant segment and the distal implant segment. The implants can be used to create an arteriovenous fistula or connect one vessel of the body to another by placement of the proximal implant segment and the distal implant segment within the vessels to be connected. The implants can include one or more anchors for securing the implant in place with respect to the vessels of the body it is connecting. The implants can also include a continuous strut or ring at a distal edge of the proximal implant segment. Also disclosed are methods for percutaneous placement of the implants, and a device for percutaneous delivery.
MITRAL VALVE SPACER DEVICE
An implantable device includes an adjustable spacer and at least one anchor. The adjustable spacer is configured to be positioned between native heart valve leaflets to reduce regurgitation therebetween. The adjustable spacer can comprise a first side and a second side opposite the first side. Each side can be adjustable between a first width and a second width. Each side can be independently moved between the first width and the second width. The adjustable spacer can be made from a sponge material.
PROSTHETIC HEART VALVE
A prosthetic valve assembly includes a radially expandable and compressible annular frame. The frame includes a plurality of interconnected struts, which include a plurality of inner struts and a plurality of outer struts. The inner struts overlap adjacent outer struts at a plurality of pivot joints. Radial expansion or compression of the annular frame causes the inner struts to pivot relative to the outer struts at the pivot joints. The assembly also includes a valvular structure having a plurality of leaflets, each leaflet having a cusp edge portion. The assembly further includes one or more leaflet-supporting cords, each having a plurality of anchoring portions and a plurality of suspended portions, each suspended portion extending between two adjacent anchoring portions. The anchoring portions are affixed to respective anchoring features of the frame adjacent the pivot joints. The cusp edge portions of the leaflets are connected to the suspended portions.
Prosthetic valves and related inventions
This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.
Collapsible cardiac implant and deployment system and methods
A collapsible device, such as an annuloplasty ring or prosthetic heart valve, is configured to be collapsed prior to being introduced into a patient via minimally-invasive access points such as port holes or intercostal incisions. A holder is configured to hold the collapsible device, and to selectively collapse the device for introduction into the patient and then re-enlarge the device at the desired deployment site. Collapsible devices include devices that can hingedly fold about hinge lines, and devices that can elongate to form substantially spiral forms with reduced diameters.
Percutaneous Valve Implants
An apparatus for implantation at an annulus (75) of an intracardiac valve includes an annuloplasty ring (110) comprising a plurality of rotatably adjoining segments (112). The ring is configured to pass over multiple threads (58), respective distal ends of which are distributed over the annulus, and, while passing over the threads, expand from a collapsed state to an expanded state by virtue of the segments rotating with respect to each other. The apparatus further comprises a lock (114), configured to lock the ring in the expanded state at the valve by inhibiting rotation of the segments with respect to each another. Other embodiments are also described.
TISSUE PACKAGING AND METHOD OF USING SAME
The present disclosure provides tissue matrix packaging devices and methods of use. The packaging can be used to help a tissue matrix sample retain its shape when being stored or transported.
