    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an inner shaft having a distal end region. A valve implant may be releasably coupled to the distal end region. The valve implant may be capable of shifting between an elongated configuration and an expanded configuration. A post assembly may be disposed along the valve implant. The post assembly may include a release member that is axially slidable along the post assembly. The medical device may also include a rod designed to engage the release member. The rod may be designed to shift the valve implant between the elongated configuration and the expanded configuration. Axially shifting the release member along the post assembly may release the rod from the post assembly and deploy the valve implant.

    Abstract: A medical device handle may include a handle housing including a cavity disposed within the handle housing. The medical device handle may include a carriage assembly disposed within the cavity and operatively connected to the tubular member and the medical implant, the carriage assembly being longitudinally movable between a distal position and a proximal position by rotation of a control knob with respect to the handle housing, the control knob being disposed around a proximal end of the handle housing. The carriage assembly may include a carriage member, a first sliding member, a second sliding member, and a locking element configured to releasably fix the first sliding member and the second sliding member relative to the carriage member. The locking element may be rotatable relative to the handle housing.

    Abstract: A replacement heart valve implant may include a tubular anchor member actuatable between a delivery and a deployed configuration, the tubular anchor member including an inflow end, an outflow end, and a plurality of anchor member intersection points, and defining a longitudinal axis extending from the inflow end to the outflow end, a plurality of valve leaflets, and a seal member secured to the tubular anchor member at the inflow end. An end surface of each of the plurality of valve leaflets may abut an inner-facing surface of the seal member. The plurality of valve leaflets each define a secured end and a free end. The secured end may be attached to the seal member adjacent the inflow end. The secured end may define the end surface, and the end surface may face toward the outflow end when the plurality of valve leaflets is in an everted position.
