Abstract: A replacement heart valve system may include a replacement heart valve implant including an expandable framework configured to shift from a radially collapsed to a radially expanded configuration, wherein the framework is self-biased toward the radially expanded configuration, and a plurality of valve leaflets attached to the framework. The replacement heart valve system may include an implant delivery system including a handle and an elongate shaft assembly including a tubular member fixedly attached to the handle, and an implant holding portion configured to constrain the framework in the radially collapsed configuration. The elongate shaft assembly includes an expandable balloon disposed on the tubular member within the implant holding portion, the balloon being configured to shift between deflated and inflated configurations. When the framework is constrained within the implant holding portion, at least a portion of the framework extends distal of the balloon in the deflated configuration.
