1. A system for implanting a flow modifying device in vasculature of a heart, the system comprising:
a flow modifying device comprising:
a tubular body comprising:
a first opening located at a proximal end of the tubular body;
a second opening located at a distal end of the tubular body; and
a neck positioned between the first opening and the second opening, wherein the tubular body is configured to expand from a first configuration to a second configuration, wherein in the second configuration the first opening comprises a first diameter and the neck comprises a second diameter smaller than the first diameter; and
a guide catheter comprising:
a flexible elongate shaft comprising:
a proximal portion comprising a fitting for receiving an insertion instrument; and
a distal portion comprising a distal tip configured to be receivable by the first opening of the tubular body when the tubular body is in the second configuration, wherein the distal tip comprises an enlarged tip to prevent the flexible elongate shaft from passing through the neck of the flow modifying device when the tubular body is in the second configuration.
