More Information
Summary:An apparatus includes a handle, a guide member, a dilation catheter, a guidewire, and first and second movement assemblies. The dilation catheter is slidably housed within the handle and is slidable relative to the guide member. The guidewire is translatable relative to the dilation catheter. The first movement assembly is configured to actuate relative to the handle and includes a first body fixed with the dilation catheter and a first coupling member. The second movement assembly is proximal in relation to the first movement assembly and includes a second body and a second coupling member. The second body is configured to selectively fix to the guidewire and actuate relative to the handle. The first coupling member and the second coupling member are configured to connect the first movement assembly and the second movement assembly to translate together relative to handle in response to distal translation of the first movement assembly.
