SELF-ACTUATING SEALING PORTIONS FOR PARAVALVULAR LEAK PROTECTION

St. Jude Medical, Cardiol...

1. A prosthetic heart valve for replacing a native valve, comprising:
a collapsible and expandable stent having a proximal end and a distal end;
a plurality of elongated legs, each of the legs having a first end coupled to the stent and a second free end, the legs being
configured to transition from an extended configuration to a relaxed configuration;

a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets and a cuff disposed on a
portion of the stent and about the plurality of leaflets; and

a sealing portion connected to the plurality of legs, the sealing portion forming a sealing structure upon the transition
of the plurality of legs from the extended configuration to the relaxed configuration;

wherein the sealing portion includes a toroidal sealing ring coupled to the plurality of legs, the toroidal sealing ring being
configured to move from a first position spaced away from the proximal end of the stent to a second position at least partially
disposed over the valve assembly upon the transition of the plurality of legs from the extended configuration to the relaxed
configuration.

COMMISSURE ATTACHMENT FEATURE FOR PROSTHETIC HEART VALVE

St. Jude Medical, Cardiol...

1. A prosthetic heart valve, comprising:
a collapsible and expandable stent having a proximal end, a distal end, an annulus section adjacent the proximal end and an
aortic section adjacent the distal end, the stent including a plurality of struts;

a plurality of commissure features disposed on the stent and coupled to selected ones of the struts, each commissure feature
including a body having a proximal end adjacent the annulus section and a distal end adjacent the aortic section, and at least
one eyelet in the body, the body being coupled to upper struts near the aortic section; and

a collapsible and expandable valve assembly, including a plurality of leaflets, at least one of the leaflets being connected
to the at least one eyelet and to at least one of the upper struts via a suture pattern.

SYSTEM AND METHOD FOR DETECTING SHEATHING AND UNSHEATHING OF LOCALIZATION ELEMENTS

St. Jude Medical, Atrial ...

1. A method of detecting a localization element/sheath state change with a localization system, comprising:
establishing a localization field using a plurality of localization field generators;
obtaining at least one localization signal from at least one catheter-borne localization element positioned within the localization
field via an introducer sheath, the at least one localization signal including an in-phase component and a quadrature component;
and

detecting a localization element/sheath state change for the at least one catheter-borne localization element based on the
quadrature component of the at least one localization signal, wherein detecting the localization element/sheath state change
comprises detecting withdrawal of the at least one localization element into the introducer sheath based upon the quadrature
component of the at least one localization signal deviating from a reference value by more than a preset amount.
