摘要： A medical device apparatus may include a medical implant including an anchor member configured to actuate between a delivery configuration and a deployed configuration operatively connected to a delivery system, the delivery system including an outer sheath and an inner catheter disposed within the outer sheath, and a sheathing aid connecting the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon relative closing movement therebetween. The sheathing aid may include a plurality of tethers extending from the inner catheter to a proximal end of the anchor member, and a release mechanism slidably disposed within a coupler ring coupled to a distal end of the inner catheter. The plurality of tethers may be releasably coupled to the release mechanism.

摘要： A valve replacement implant may include an expandable anchor member having a proximal end and a distal end, the anchor member being actuatable between a delivery configuration and a deployed configuration. A plurality of locking mechanisms may be configured to secure the anchor member in the deployed configuration. Each locking mechanism may include an axially movable post including a leg portion extending inwardly therefrom, and a receiving portion fixed to the anchor member, the receiving portion being configured to slidably receive the post. A plurality of valve leaflets may be disposed within a central lumen of the anchor member, the plurality of valve leaflets being secured to the leg portions of the plurality of locking mechanisms. The plurality of locking mechanisms may be releasably attached to a delivery device.

摘要： A medical device apparatus may include a medical implant including a braided anchor member configured to actuate between a delivery configuration and a deployed configuration operatively connected to a delivery system. The delivery system may include a handle, an outer sheath extending distally from the handle, and an inner catheter disposed within the outer sheath. A sheathing aid may connect the delivery system to the medical implant, the sheathing aid being configured to guide the medical implant into the outer sheath upon relative closing movement therebetween. The sheathing aid may include a plurality of arms extending from the inner catheter to a proximal end of the braided anchor member. At least one arm of the plurality of arms may comprise a core member having a width and a flexible member positioned about the core member.

摘要： 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.

摘要： 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.

摘要： 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.
