    摘要: An improved holder and storage system for a tissue-type prosthetic mitral heart valve that constricts the commissure posts of the valve and prevents suture looping. A rod axially movable relative to the holder tensions lengths of attachment sutures that extend between the commissure post tips to create a tent and flex the tips inward, thus helping to prevent looping of any of an array of pre-implanted sutures around the leading tips during delivery of the valve. The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.

    摘要: Anchor devices and methods can be used to secure a prosthetic valve to a native valve annulus. The anchor device can be a separate expandable element from the prosthetic valve that is first advanced to the annulus and deployed, after which an expandable prosthetic valve is advanced to within the annulus and deployed. The combination of the two elements can apply a clamping force to the valve leaflets which holds the prosthetic valve in place. The anchor device can have a lower or ventricular portion and an upper or atrial portion. The anchor device can include one or more leaflet clamping portions. One, two, or more upstanding vertical posts between the clamping portions can extend upward at the valve commissures and support the upper portion, which can include one or more structures for leak prevention.

    摘要: A device for crimping a radially expandable and collapsible prosthetic valve comprises a crimping loop having a first end portion, a second end portion, and a loop portion extending between the first and second end portions and defining an opening configured to receive the prosthetic valve. The crimping loop is movable between a first state in which the opening has a first diameter and a second state in which the opening has a second diameter smaller than the first diameter such that when the prosthetic valve is positioned within the loop portion, movement of the crimping loop from the first state to the second state is effective to reduce a diameter of the prosthetic valve. A method for crimping a prosthetic valve comprises reducing a diameter of an opening of a crimping loop, thereby radially compressing an at least partially expanded prosthetic valve disposed within the opening.

    摘要: Disclosed are cardiac shunts and method of delivery, and in particular, to a shunt to reduce elevated left atrial pressure (LAP). The methods include forming a puncture hole between the left atrium and the coronary sinus, widening the puncture hole, and placing an expandable shunt within the widened puncture hole. A first catheter having a side-extending needle may be used to form a puncture into the left atrium. A second catheter extends along a guidewire and an expandable shunt with distal and proximal flanges is expelled therefrom into the puncture. The shunt defines a blood flow passage therethrough that permits shunting of blood from the left atrium to the coronary sinus when the LAP is elevated. The shunt is desirable formed of a super-elastic material and manipulated with control rods. The shunt defines a tilted flow tube that facilitates collapse into the catheter.

    摘要: A device for crimping a radially expandable and collapsible prosthetic valve comprises a coiled wire frame having a longitudinal opening extending from a proximal end to a distal end thereof The opening has a first state and a second state, the opening in the first state having a first diameter dimensioned to receive the prosthetic valve in an expanded or partially crimped configuration therein, and the opening in the second state having a second diameter dimensioned to receive the prosthetic valve in a crimped configuration. The coiled wire frame has a first end coupled to a first member and a second end coupled to a second member. The first member is movable relative to the second member to convert the coiled wire frame from the first state to the second state.
