1. An assembly, comprising:
a base including a first infusion port, a second infusion port, and a target magnet housing;
a first magnet and a second magnet at least one of which is disposed in the target magnet housing, wherein:
the first target magnet includes a magnetic pole proximal a first side of the target magnet housing, and
the second magnet includes a magnetic pole opposite to the magnetic pole proximal the first side of the target magnet housing,
a locator assembly including a locator base and a locator housing, the locator base including:
a cavity formed within the locator base, and
the locator base has a planar surface that is substantially orthogonal to a side of the locator housing; and
at least two locator magnets respectively positioned about the cavity within the locator assembly, wherein:
the first infusion port and the second infusion port align with a first aperture and a second aperture of the locator assembly in response to the first magnet and the second magnet being magnetically coupled to the at least two locator magnets, and
at least one of the at least two locator magnets extends from a side of the locator base and into a portion of the locator housing.
