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 stented valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.

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.

Systems for the simulation of percutaneous medical procedures are disclosed. The systems can include a simulated vasculature including a first component configured to allow for introduction of a medical device into the system through an introductory port, a second component connected to the first component and shaped to simulate a portion of a human vasculature, and a third component connected to the second component and shaped to simulate a delivery site for the medical procedure. The system can be configured to allow for a medical device to be delivered to the third component by passing through the introductory port of the first component and passing through the second component. The system can be configured to replicate simulated conditions of use for the medical procedure. Methods for simulating a percutaneous medical procedure using a simulated vasculature are also disclosed.

Physiologic simulator system

A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.

Systems () for the simulation of percutaneous medical procedures are disclosed. The systems can include a simulated vasculature including a first component () configured to allow for introduction of a medical device into the system through an introductory port, a second component () connected to the first component and shaped to simulate a portion of a human vasculature, and a third component () connected to the second component and shaped to simulate a delivery site for the medical procedure. The system can be configured to allow for a medical device to be delivered to the third component by passing through the introductory port of the first component and passing through the second component. The system can be configured to replicate simulated conditions of use for the medical procedure. Methods for simulating a percutaneous medical procedure using a simulated vasculature are also disclosed.

A stented valve prosthesis for implantation within a native mitral valve having a generally tubular expandable stent structure having a first end, a second end, a central body portion having one or more openings, and a longitudinal axis. A wing portion extends outwardly from the stent structure and away from the longitudinal axis of the stent structure in an expanded deployed configuration. A radius of the wing portion is greater than a radius of the central body portion in the expanded deployed configuration, and the wing portion fits within one of the openings in the central body portion of the stent structure in a crimped delivery configuration. A valve structure having a plurality of leaflets is attached to an interior of the stent structure.

A stent frame including an annular portion having first and second ends, a central longitudinal axis, and a wire portion with at least two extending posts and a generally sinusoidal series of peaks and valleys between each of the at least two extending posts; an atrial portion extending from the first end of the annular portion, wherein the atrial portion includes a plurality of flares that extend radially outward relative to the longitudinal axis of the annular portion; and a ventricular portion extending from the second end of the annular portion, wherein the ventricular portion includes at least one flare that extends radially outward relative to the longitudinal axis of the annular portion.

Stented heart valve devices

An annuloplasty band comprising a sheath, and a generally arcuate stiffening element disposed within the sheath. The stiffening element extends from a first end to a second end, and preferably includes eyelets at its first and second ends adapted to receive sutures to secure the annuloplasty band to a valve annulus. The annuloplasty band preferably has a low profile (e.g., a thickness less than 3 mm). In embodiments intended for mitral valve repair, the eyelets are particularly adapted to receive sutures to secure the annuloplasty band to the antero-lateral trigone and postero-medial trigone. A holder and sizer device useful with the annuloplasty band are also provided.

Annuloplasty band and method

A stented valve of two or more leaflets made of pericardium or other material having a relatively thin profile at the annulus. The leaflet surfaces are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.
