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.

Abstract: A replacement heart valve commissure assembly may include a locking mechanism including a first locking portion spaced apart from a second locking portion in a delivery configuration and configured to engage with the second locking portion in a deployed configuration, wherein the first locking portion is longitudinally actuatable relative to the second locking portion between the delivery and deployed configurations. The commissure assembly may include a first valve leaflet and a second valve leaflet each secured to the first locking portion. A first sleeve portion of the first valve leaflet may be fixedly attached to a first fabric sleeve wrapped around a first leg of the first locking portion by a first filament, and a second sleeve portion of the second valve leaflet may be fixedly attached to a second fabric sleeve wrapped around a second leg of the first locking portion by a second filament.

Abstract: A containment vessel for storing and rinsing a medical implant coupled to a delivery system having an outer sheath may include a hollow element having a wall, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the lumen of the hollow element being configured and adapted to contain a medical implant in a partially-deployed configuration during storage and rinsing of the medical implant and a proximal end cap including a secondary proximal end cap removably secured to the proximal end cap and configured to reversibly seal the proximal end cap to the outer sheath, thereby establishing a closed fluid connection between the lumen of the hollow element and a lumen of the outer sheath. The proximal end cap may include a sheathing guide configured and adapted to direct the medical implant into the lumen of the outer sheath.

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.
