1. A biopsy device, comprising:
an outer member having a first lumen defined by a first distal end of the outer member and a first proximal end of the outer member, and a first magnet positioned at the first distal end of the outer member;
an inner member disposed within the first lumen and movable relative to the outer member, the inner member having a second lumen defined by a second distal end of the inner member and a second proximal end of the inner member;
a shaft disposed within the second lumen and movable relative to the inner member;
a distal tip at a distal end of the shaft, the distal tip having a first proximally-facing surface, a second proximally-facing surface positioned proximal of the first proximally-facing surface, and a second magnet positioned at the first proximally-facing surface of the distal tip; and
at least one cutting tool coupled to the second proximally-facing surface of the distal tip and coupled to the second distal end of the inner member;
wherein the at least one cutting tool is configured to move from a collapsed configuration to an expanded configuration in response to the shaft translating relative to the second lumen of the inner member, with the at least one cutting tool disposed within the second lumen when in the collapsed configuration and extending radially-outward from the shaft when in the expanded configuration,
wherein the at least one cutting tool is biased to the expanded configuration, and wherein the first magnet of the outer member magnetically attracts to the second magnet of the distal tip when the at least one cutting tool is in the collapsed configuration to maintain the at least one cutting tool in the collapsed configuration.
