    Abstract: A replacement heart valve locking mechanism may include a buckle member fixedly attached to a tubular anchor member defining a central longitudinal axis, a post member axially translatable relative to the buckle member, and an actuator member releasably connected to the post member at an attachment point. The post member may include a latch portion configured to engage a catch formed in the buckle member such that movement of the post member distally relative to the buckle member is prevented. The attachment point may be disposed proximal of the latch portion. Circumferential translation of the latch portion about the central longitudinal axis may disengage the latch portion from the catch.

    Abstract translation: 置换心脏瓣膜锁定机构可以包括固定地连接到限定中心纵向轴线的管状锚定构件的扣环构件，相对于带扣构件可轴向平移的柱构件以及在附接点可释放地连接到柱构件的致动器构件。 柱构件可以包括闩锁部分，其构造成接合形成在带扣构件中的卡扣，从而防止柱构件相对于带扣构件向远侧运动。 附接点可以设置在闩锁部分的近侧。 闩锁部分围绕中心纵向轴线的周向平移可以使闩锁部分与卡扣脱离。

    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 defining a central longitudinal axis extending from an upstream end to a downstream end may include an expandable anchor member configured to shift between a delivery configuration and a deployed configuration, a circumferential support member distinct from and attached to the expandable anchor member, at least a portion of the circumferential support member extending downstream of the expandable anchor member, and a plurality of valve leaflets secured to the expandable anchor member. The plurality of valve leaflets may include a valve leaflet commissure movable from a first longitudinal position relative to the downstream end in the delivery configuration to a second longitudinal position relative to the downstream end in the deployed configuration.

    Abstract: A handle for a medical device system may include a hollow elongate handle housing, a first lead screw disposed within the hollow elongate handle housing, a deployment mechanism configured to actuate a medical implant positioned at a distal end of the medical device system, the deployment mechanism being operatively engaged with the first lead screw, and a control knob rotatably disposed around a proximal end of the hollow elongate handle housing. The first lead screw may be spaced apart from the control knob. Rotation of the control knob in a first direction may cause rotation of the first lead screw in the first direction.

    Abstract: A medical device handle for percutaneous delivery of a medical device implant may include an elongated handle housing having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end; a rotatable collar disposed about the proximal end of the handle housing; and a rotatable control knob disposed about a proximal portion of the rotatable collar. The rotatable collar may include a first internally-facing longitudinal slot extending less than a full length of the rotatable collar and terminating proximally at a distally-facing wall of an internally-facing circumferentially-oriented slot. The rotatable control knob may be configured to actuate the medical device implant between a delivery configuration, a deployed configuration, and a released configuration.
