Abstract
A biopsy marker having a spring-loaded anchor. The biopsy marker includes an insertion orientation and an anchored orientation. The lateral span/cross-sectional area of the marker is configured to change when transitioning between the insertion orientation and the anchored orientation. In an embodiment, the spring-loaded anchor is configured to spring about a predefined rotational axis. An embodiment of the biopsy marker may be comprised of a single wire construction.
Claims20
A biopsy marker, comprising:
- a bioabsorbable component having a hydrated state and a dehydrated state, wherein the bioabsorbable component changes in size when transitioning between the dehydrated state and the hydrated state;
- a non-bioabsorbable component at least partially residing within the bioabsorbable component, the non-bioabsorbable component including:
- a body section having a predefined shape;
- a first anchoring arm;
- a first spring component in operable communication with the first anchoring arm;
- and
- wherein hydrating the bioabsorbable component changes the size of the bioabsorbable thereby altering a force applied onto the non-bioabsorbable component and causing the non-bioabsorbable component to move to an anchoring orientation.

A biopsy marker, comprising:
- a bioabsorbable component having a hydrated state and a dehydrated state, wherein the bioabsorbable component is configured to transition between the dehydrated state and the hydrated state;
- a non-bioabsorbable component, the non-bioabsorbable component including:
- a body section;
- a first anchoring arm interconnected with the body section;
- a first spring component in operable communication with the first anchoring arm;
- the bioabsorbable component in operable communication with the first anchoring arm when the bioabsorbable component is in the dehydrated state, whereby the dehydrated bioabsorbable component applies a force on the first anchoring arm that is greater than a spring force of the first spring component such that the first anchoring arm remains in a first orientation when the bioabsorbable component is in the dehydrated state;
- the bioabsorbable component applying a lesser force on the non-bioabsorbable component when the bioabsorbable component is in the hydrated state in comparison to the force applied by the dehydrated bioabsorbable component, wherein the lesser force is less than the spring force of the first spring component;
- and
- the first spring component thereby causing the non-bioabsorbable component to move to an anchoring orientation when the bioabsorbable component transitions from the dehydrated state to the hydrated state.

A biopsy marker, comprising:
- a bioabsorbable component having a hydrated state and a dehydrated state, wherein the bioabsorbable component is configured to transition between the dehydrated state and the hydrated state;
- a non-bioabsorbable component, the non-bioabsorbable component including:
- a body section having a predetermined shape;
- a first anchoring arm interconnected with the body section;
- a first spring component in operable communication with the first anchoring arm;
- at least a portion of the non-bioabsorbable component residing within the bioabsorbable component when the bioabsorbable component is in the dehydrated state;
- wherein hydrating the bioabsorbable component alters a force applied onto the non-bioabsorbable component and causes the non-bioabsorbable component to move to an anchoring orientation.
