1. A method of explanting an anchored blood pump from a body conduit, the method comprising:
with the blood pump removably coupled to an anchor that is anchored to a wall of the body conduit at a delivery site, decoupling the blood pump from the anchor such that the anchor transitions from a partially-expanded, secured configuration, in which a first portion of the anchor contacts the wall of the body conduit and a second portion of the anchor is secured to contacting the blood pump, to an expanded, released configuration in which the second portion of the anchor is unsecured from the blood pump; and
with the anchor anchored to the wall of the body conduit at the delivery site, removing the blood pump from the body conduit, thereby leaving the anchor anchored to the wall of the body conduit at the delivery site.
