    摘要： A crimping tool for use with a collapsible prosthetic valve having a stent frame with a plurality of cell openings, and a valve structure assembled in the stent frame. The crimping tool includes a plurality of resilient tines defining an array around a longitudinal axis of the crimping tool. The array has a first cross-section in an expanded state and a second cross-section less than the first cross-section in a collapsed state. The plurality of tines are adapted to intersect the plurality of cell openings in an assembled position of the crimping tool on the prosthetic valve to prevent pinching of the valve structure by the stent frame as the prosthetic valve is collapsed.

    摘要： A prosthetic heart valve is circumferentially collapsible for less invasive delivery into a patient. The valve re-expands to operating size at the implant site in the patient. A frame structure of the valve includes restraining structure that can help to push one or more of the patient's native heart valve leaflets radially outwardly so that this native leaflet tissue does not interfere with the operation or service life of the prosthetic valve.

    摘要： A closure device includes a delivery member, a sealing material applicator, and an expandable member. The delivery member is insertable through a tissue tract to a vessel puncture. The sealing material applicator is configured to supply a volume of sealing material to the delivery member and includes first and second multi-chamber devices and a valve assembly. Each chamber of the first and second multi-chamber devices holds a component of the sealing material, and operating the valve assembly permits mixing of at least some of the components prior to connecting the sealing material applicator to the delivery member. The expandable member is positionable within the vessel to temporarily seal closed the vessel puncture from within the vessel. The closure device is operable to deliver the sealing material from the sealing material applicator, through the delivery member, and to the tissue tract to seal closed the vessel puncture from outside the vessel.

    摘要： An adjustment tool enables manipulation of a prosthetic anatomical device such as an annuloplasty ring. The tool includes a compression member which is operative for retarding rotation of the adjustment shaft to preclude inadvertent rotation thereof during use of the tool by the surgeon. A locking device is associated with the adjustment tool to enable the releasable attachment of the tool to the anatomical device during its adjustment by manipulation of the tool. The locking device is oriented into operative and inoperative positions by the engagement and disengagement of locking elements. A scale may be provided on the adjustment tool to assist a surgeon in determining the size or amount of adjustment to the size of the anatomical device during its adjustment.

    摘要： A heart valve annulus sizer is provided for measuring a valve to be fitted with an annuloplasty ring. The sizer may include a body having a peripheral portion defining an opening, at least one rib disposed within the opening and dividing the opening into at least a first opening and a second opening, and an anchor disposed on and projecting from the body. The sizer may include a length of suture connected to the body. The anchor may include an aperture adapted to receive the length of suture. A method of using the sizer is provided that includes grasping the sizer with an instrument and positioning the sizer adjacent to a valve into a position suitable to allow for measurement of the valve.

    摘要： 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.
