    Abstract: A locking mechanism for a medical implant may comprise a buckle member fixedly attached to a tubular anchor member, a post member axially translatable relative to the buckle member, wherein the post member includes a first proximal portion and a second proximal portion, the first proximal portion being disposed adjacent to the tubular anchor member and the second proximal portion being disposed radially inward of the first proximal portion, and an actuator element including a lateral protrusion proximate a distal end thereof, the actuator element being releasably coupled to the post member. The post member may include an engagement portion configured to engage the buckle member such that movement of the post member distally relative to the buckle member is prevented. The second proximal portion may be configured to deflect away from the first proximal portion to release the actuator element.

    Abstract: A replacement heart valve implant may include a braided anchor member configured to actuate between a delivery configuration and a deployed configuration formed from a plurality of filaments, a circumferential seal member disposed about a distal portion of the anchor member and including a reinforcing band disposed at a distal end thereof, and a plurality of valve leaflets connected to the anchor member. The reinforcing band is secured to the anchor member adjacent a distal end of the anchor member by a plurality of lashings each attached to two individual filaments. The plurality of filaments defines a body section, a proximal crown section, and a distal crown section, wherein the proximal crown section includes a first plurality of end loops and a second plurality of end loops, wherein a proximalmost extent of the first plurality of end loops and the second plurality of end loops varies.

    Abstract: A locking mechanism for a medical implant may include a buckle member, a post member axially translatable with respect to the buckle member, the post member including a receiving portion proximate a proximal end of the post member, a distal end, a laterally-arched central body portion extending between the receiving portion and the distal end, and a cantilevered leg extending proximally from the distal end, and an actuator element including a proximal shaft portion and a distal engagement portion, the distal engagement portion being configured to releasably engage the receiving portion of the post member. The proximal shaft portion may be pivotable with respect to the distal engagement portion.

    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.

    IPC: A61F2/24

    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.
