摘要： 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.

摘要： A valve sizer for determining an appropriate replacement valve size when performing a heart valve replacement procedure is provided. In one version the valve sizer has a hollow shaft with proximal and distal ends. A movable sizing element couples to the distal end of the shaft and is radially expandable between first, contracted and second, expanded positions. An actuator assembly on a handle includes an actuator coupled to a clutch member via a ball-spring-detent clutch. A rod extends through the shaft and maintains a fixed distance between the handle and a distal hub in the sizing element. Movement of the actuator causes axial movement of the shaft, thereby causing radial expansion of sizing petals relative to the hub. The clutch slips when a predetermined reaction force from the surrounding valve annulus is met by the petals.

摘要翻译： 动态，可调节瓣环成形术环形筛分器可以包括可调整的环形复制件，其可以通过对应于可用的假体瓣环成形术修复环尺寸的一系列尺寸进行调整。 在环形筛分机的手柄部分上的调节触发器的致动器可以移动延伸穿过可延展的轴并通过形成环形复制件的多个铰接段的张力线。 张力线的位移导致相邻铰接段之间的接头弯曲，从而减小环形复制体的总体尺寸。 释放张力线可以允许弹性延伸线作用在环形复制品上，将环形复制品放大到最大静止尺寸。 以这种方式，可以使用单个装置来确定瓣环成形术假体的适当尺寸，而不需要多个静态环形筛分器，其需要单独的插入和放置用于常规的试验和误差尺寸测量方法。

摘要： Suture locking clamps for securing prostheses such as heart valves or annuloplasty rings with sutures and without knots improve the ease of implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.

摘要： A device and method for deploying self-cinching surgical clips. The device accesses at least two layers of tissue or material from only one side of the tissue or material and punctures through the two layers of tissue or material. The various configurations of clips disclosed herein are made of a superelastic material such as Nitinol, and have a constrained and a relaxed state, and no sharp edges or tips so as to reduce tissue irritation following deployment. The clip is disposed within the housing of the delivery device and held in a constrained state by a tube assembly until deployment wherein the clip assumes its relaxed state, where the ends of the clip are brought into close approximation, thereby securing the layers of tissue or material together.

摘要： Devices for securing prostheses such as heart valves or annuloplasty rings with sutures and without using knots are disclosed. The devices are particularly well suited for traditional surgery or minimally invasive surgery, and improve the ease of implantation by eliminating surgical knots a clinician would normally tie in the limited space in and around the implant site. The devices have opposed the clamp halves surrounded by a coil spring. Sutures pass between the clamp halves and the coil spring has an inner coil diameter sufficient to compress the sutures between the clamp. A retention member positioned between the clamp halves maintains a minimum space and therebetween to enable the locking device to be slid along the sutures into position, and to adjust the tension of the sutures therethrough. A delivery tool may be used to deliver and deploy the locking devices.

摘要： A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.
