    Abstract: A dynamic, adjustable annuloplasty ring sizer can include an adjustable ring replica, which can be adjusted through a range of sizes corresponding to available prosthetic annuloplasty repair ring sizes. Actuation of an adjustment trigger on a handle portion of the ring sizer can displace tension wires that extend through a malleable shaft and through a plurality of articulating segments that form the ring replica. Displacement of the tension wires causes flexion of the joints between adjacent articulating segments, thereby reducing the overall size of the ring replica. Releasing the tension wires can allow an elastic extension wire to act on the ring replica, enlarging the ring replica to its maximum, at-rest size. In this manner, the appropriate size of annuloplasty ring prosthesis can be determined with a single device, without requiring a plurality of static ring sizers that require individual insertion and placement for the conventional trial-and- error sizing methods.

    Abstract: A directional flow valve in a cardiovascular prosthesis test system includes a regurgitant flow passage. Forward flow from a pump through the valve is unrestricted and allowed to pass freely through the directional flow valve. Regurgitant flow is allowed across the directional flow valve to reduce a negative pressure gradient across the prosthetic device. The volume of regurgitant flow is controllable by changing a size of the regurgitant flow pathway.

    Abstract: A ring applicator for applying elastic rings to anatomical tissue during surgical procedures includes an inner member with a forceps movably disposed within a middle tubular member having a distal end configured to hold a plurality of elastic rings in an expanded state and a proximal end with a plurality of longitudinally spaced steps. The middle tubular member is movably disposed in an outer tubular member, and an adjustable stop mechanism is mounted on the proximal end of the outer tubular member to limit axial movement of the outer tubular member relative to the middle tubular member to select which rings are to be ejected. A distal handle is connected with the inner member via slots in the outer and middle tubular members, and a proximal handle is pivotally connected to the middle tubular member via a slot in the outer tubular member. A pusher has a distal end movable between a latched or locked position where the distal end of the pusher protrudes into apertures in the outer and middle tubular members to prevent pivotal movement of the proximal handle and an unlatched or unlocked position where the distal end of the pusher is disengaged from the aperture in the middle tubular member to permit pivotal movement of the proximal handle in order to move the outer tubular member axially relative to the middle tubular member to eject an elastic ring. Distal portions of the outer and middle tubular members are preferably transparent with scale markings formed thereon to allow the surgeon to accurately determine the length of the tissue disposed within the middle tubular member prior to ejecting a ring. A prerelease feature is also disclosed for unlocking the pusher to allow ejection of a ring when the forceps has not been completely withdrawn in to the middle tubular member.

    Abstract: A load-controlled accelerated wear testing system to test cardiovascular prostheses that enables a user to tune pulse waveform by adjusting the output loading pressure of a linear motor driving the testing system. A portion of the testing system is open to the atmosphere during testing, allowing a relatively lower threshold pressure necessary to drive fluid across the prosthesis during testing. The contemplated tester can be set up in an array of multiple testers each capable of individual tuning and data-collection without undesirably cross- talking. Its novel feature of single -block construction out of a transparent material also allows direct visualization of the prosthesis during testing.
