A prosthetic heart valve includes a stent having an expanded condition and a collapsed condition. The stent includes a plurality of distal cells, a plurality of proximal cells, a plurality of support struts coupling the proximal cells to the distal cells, and at least one support post connected to a plurality of proximal cells. The proximal cells are longitudinally spaced apart from the distal cells. Various strut configurations and connections of the struts to the proximal cells and of the proximal cells to the support post improve stent flexibility and reduce stress in the valve leaflets.

Stent features for collapsible prosthetic heart valves

Apparatus for use with a prosthetic heart valve includes a holder, to which the heart valve is releasably attached, and an elongated handle. The handle can be connected to the holder simply by pushing a distal end of the handle straight into a recess in the holder. After this has been done, the holder preferably releasable latches onto the handle, and the handle can also be rotated about its longitudinal axis to transmit torque to the holder (e.g., a rotatable portion of the holder). Rotation of such a rotatable portion of the holder can be used to deflect portions of the valve radially inward. This operation of a rotatable portion of the holder is preferably one-way-only. The handle can be released from the holder at any time, and it can similarly be reconnected to the holder at any time.

Prosthetic heart valve holder apparatus

A stent () for use in a prosthetic heart valve has an annulus section () adapted for placement within the ' leaflets and annulus of the native heart valve. The annulus section has latch members () adapted to engage the leaflets of the native heart valve when prosthetic valve is implanted in the native valve. The latch members may hold the leaflets in engagement with the annulus section, and help to retain the prosthetic valve in position. The annulus section may have a non-circular cross-sectional shape.

Axially anchoring collapsible and re-expandable prosthetic heart valves for various disease states

A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.

Collapsible and re-expandable prosthetic heart valve cuff designs and complementary technological applications

Prosthetic heart valves, which are collapsible to a relatively small circumferential size for less invasive delivery into a patient and which then re-expand to operating size at an implant site in the patient, include a collapsible/expandable stent-like supporting structure and various components of flexible, sheet-like material that are attached to the supporting structure. For example, these sheet-like other components may include prosthetic valve leaflets, layers of buffering material, cuff material, etc. Improved structures and techniques are provided for securing such other components to the stent-like supporting structure of the valve.

The present invention provides a method for designing a frequency-shifting isolator system that includes selecting, an impact absorption envelope; a geometry for the isolator mount system; and an elastomeric dampening material formed in the selected geometry. The isolator mount system is preferably configured to shift frequencies at predetermined displacements upon impact, at or before the system attains resonance.
