A delivery system for delivering an implantable stented device to a lumen of a patient, the delivery system including an elongated body having a proximal end and a distal end, a driver mechanism positioned at the proximal end of the elongated body, an elongated threaded rod located axially distal to the driver mechanism, and a sheath including an elongated tubular portion having a hollow interior portion with a first diameter that is sized for compression and retention of the implantable stented device in a compressed configuration for delivery to a body lumen.

Delivery systems and methods of implantation 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 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 stent structure including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion.

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.

A delivery system for an implantable stented device having a handle with a plurality of actuation members, each actuation member connected to one or more stent attachment elements, a sheath having a proximal end attached to the handle, and a plurality of tubes extending within the sheath. The stent attachment elements extend from distal ends of the tubes. A first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device.

Stent for prosthetic heart valves

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

Embodiments of the present invention provide prosthetic valves having sealing members on the external surface thereof. The prosthetic heart valves of the present invention are preferably delivered by catheter directly through the apex of the heart or by other close range transcatheter delivery methods. Because these methods of implantation require a shorter length of catheter, a prosthetic valve can be more accurately oriented in the desired implantation location. Fluoroscopy can be used to further assist in orientation of the valve. The sealing members of the present invention can be positioned on the prosthetic valve such that, when the prosthetic valve is implanted in a native annulus, each provided sealing member is located adjacent to a commissural point of the native valve leaflets. Because the sealing members are precisely oriented on the prosthetic valve, a physician can ensure that the sealing members are aligned with the commissural points of the native valve leaflets. In embodiments of the present invention, the prosthetic valve can have a waisted middle section, and the sealing members can be located in the waisted middle section such that the crimped diameter of the prosthetic valve is not negatively impacted by the sealing, members.
