  • Patent number: 9078781
    Abstract: A stent cover for enclosing a compressible stent during a stent crimping process, the stent cover having an outer sheath with a proximal end, a distal end, an end portion at the distal end of the sheath having a first diameter, and a stent-retaining portion adjacent to the end portion and having an uncompressed diameter that is larger than the first diameter of the end portion for retaining a stent in its uncompressed condition.

  • Patent number: 9028544
    Abstract: 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.

  • Publication number: 20080033544
    Abstract: A method for evaluating a valve annulus to determine a size of a prosthetic heart valve to be sewn to the valve annulus during heart valve replacement surgery. The prosthetic heart valve includes an annular extension having a first flexibility and a sewing ring having a second flexibility. A flexible sizer body is provided and includes an outer ring and an annular wall coupled to and extending from the outer ring. The annular wall has a flexibility substantially similar to the first flexibility of the annular extension of the prosthetic heart valve. The flexible sizer body is inserted into the valve annulus and a determination made as to fit and conformance. A prosthetic heart valve is selected based on the determination.

  • Publication number: 20060235510
    Abstract: A prosthetic heart valve system including a prosthetic heart valve and a deflection device. The deflection device includes a line and a connector assembly including a tensioning component. The line interconnects and passes through free ends of stent posts associated with the heart valve, and is further connected to the tensioning component. The tensioning component is transitionable to a tensioning state in which the line is tensioned to inwardly deflect the stent posts. In this regard, the tensioning component is self-locking relative to the line in the tensioning state, and an entirety of the line extending distal the tensioning device does not extend beyond a stent portion of the heart valve opposite the stent posts. In a preferred embodiment, a holder body is further included, coupled to the heart valve apart from the deflection device.

  • Publication number: 20060195181
    Abstract: A valve system including an aortic valve and a holder. The holder includes a holder body, which has a central portion, engagable with a holder handle, and downwardly extending leg portions that engage the valve in the areas between the commissure posts. The central portion of the holder further includes a spool located between the commissure posts, rotatable by an attached handle. Rotation of the spool draws in a tensile member passing through the commissure posts, drawing the commissure posts inward toward the spool. The tensile member passes through guides formed in the holder, configured such that they define the maximum available inward deflection of the commissure posts at the point at which the portions of the tensile member between the commissure posts assume straight configurations.

  • Publication number: 20060052867
    Abstract: A method of functionally replacing a previously implanted prosthetic heart valve. The method includes positioning a replacement prosthetic heart valve within an internal region defined by the previously implanted prosthetic heart valve. The replacement prosthetic heart valve is then physically docked to the previously implanted prosthetic heart valve. With this technique, the previously implanted prosthetic heart valve serves as a platform for securement of the replacement prosthetic heart valve to the patient's native tissue.
