Abstract: A handle for a prosthetic implant delivery apparatus includes a plurality of knobs configured to control corresponding mechanisms of the delivery apparatus. Each knob has a color that is visually distinct from other knobs to indicate a unique function. In some instances, each knob is operably coupled to an indicator viewable through a window of the handle, and the indicator shares the same color as the corresponding knob to convey a functional relationship. Rotation or manipulation of a knob causes a corresponding adjustment mechanism, such as a pull wire, to actuate a feature of the delivery apparatus, for example, to control flex in different regions of a delivery shaft. A method for delivering a prosthetic implant includes manipulating one or more colored knobs to adjust aspects of the delivery apparatus and observing movement of matching-colored indicators to verify operation prior to or during implant deployment.

Abstract: Devices and methods for handles of delivery apparatuses for prosthetic medical devices are disclosed. As one example, a handle for a delivery apparatus can include a housing having an outer wall and at least one window coupled to the outer wall of the housing. The at least one window can define at least one viewing region through the outer wall. The handle can further include at least one indicator positioned within the housing adjacent to the window. The at least one indicator can include a background member and a slider, wherein the slider is configured to slide relative to the background member.

Abstract: A delivery catheter is in various embodiments configured to deliver an anchoring device to a native valve annulus of a patient's heart, where the anchoring device can better secure a prosthesis at the native annulus. A sheath catheter may be utilized to deliver the delivery catheter and a catheter for deploying a prosthetic valve to the anchoring device.
