The invention provides a device for percutaneously implanting an imaging marker for identifying a location within a tissue mass. The subcutaneous imaging marker comprises at least a first element and a second element, each of which have a primary imaging mode. The primary imaging mode of the first element is different from that of the second element.
1. An imaging marker for the subcutaneous marking of tissue, the imaging marker comprising: a composite body configured for delivery through a cannula of a marker introducer, wherein the composite body includes a first non-bioabsorbable article and a second non-bioabsorbable article, wherein the fir
1. An imaging marker for the subcutaneous marking of tissue, the imaging marker comprising: a composite body configured for delivery through a cannula of a marker introducer, wherein the composite body includes a first non-bioabsorbable article and a second non-bioabsorbable article, wherein the first non-bioabsorbable article is secured the second non-bioabsorbable article with direct contact between the first non-bioabsorbable article and the second non-bioabsorbable article;wherein the first non-bioabsorbable article is a rigid article viewable via a first primary imaging mode and wherein the second non-bioabsorbable article is a flexible article viewable via a second primary imaging mode that is different from the first primary imaging mode,wherein the rigid article comprises a head with an anchor, andwherein the rigid article comprises a loop from which extends at least one foot, with the loop surrounding an outer surface of the flexible article to form the head and the at least one foot forming the anchor. 2. The imaging marker of claim 1 wherein the loop has an inner diameter and the flexible article has an outer diameter, wherein the flexible article is configured to expand so that the outer diameter is greater than the inner diameter to effect embedding of the rigid article in the flexible article. 3. The imaging marker of claim 2 wherein the inner diameter is between 0.010 and 0.030 inches. 4. The imaging marker of claim 1 wherein the flexible article is configured to be folded against the at least one foot so that the composite body is sized to be received within a hollow needle having a gauge of less than 20. 5. A composite tissue marker sized for delivery through a lumen of a cannula into a patient, comprising: a first unitary non-bioabsorbable article having a securing portion; anda second unitary non-bioabsorbable article disposed adjacent to the securing portion of the first unitary non-bioabsorbable article, wherein the securing portion of the first unitary non-bioabsorbable article exerts a force on the second unitary non-bioabsorbable article to secure the first unitary non-bioabsorbable article to the second unitary non-bioabsorbable article to form the composite tissue marker,wherein the first unitary non-bioabsorbable article is a unitary metal article having the securing portion and the second unitary non-bioabsorbable article is a unitary non-bioabsorbable polymer article that is disposed adjacent to the securing portion of the unitary metal article, wherein the securing portion of the unitary metal article exerts the force on the unitary non-bioabsorbable polymer article to secure the unitary metal article to the unitary non-bioabsorbable polymer article to comprise the composite tissue marker, andwherein the securing portion of the unitary metal article forms a loop, and the unitary non-bioabsorbable polymer article is an elongate member having a first end and a second end, the elongate member being inserted into the loop, with the loop being positioned between the first end and the second end of the elongate member. 6. A composite tissue marker sized for delivery through a lumen of a cannula into a patient, comprising: a first unitary non-bioabsorbable article having a securing portion; anda second unitary non-bioabsorbable article disposed adjacent to the securing portion of the first unitary non-bioabsorbable article, wherein the securing portion of the first unitary non-bioabsorbable article exerts a force on the second unitary non-bioabsorbable article to secure the first unitary non-bioabsorbable article to the second unitary non-bioabsorbable article to form the composite tissue marker,wherein the first unitary non-bioabsorbable article is a unitary metal article having the securing portion and the second unitary non-bioabsorbable article is a unitary non-bioabsorbable polymer article that is disposed adjacent to the securing portion of the unitary metal article, wherein the securing portion of the unitary metal article exerts the force on the unitary non-bioabsorbable polymer article to secure the unitary metal article to the unitary non-bioabsorbable polymer article to comprise the composite tissue marker, andwherein the securing portion of the unitary metal article includes a loop and the unitary non-bioabsorbable polymer article is a cylinder, the cylinder being positioned in the loop of the unitary metal article. 7. A composite tissue marker configured for percutaneous placement into tissue via an introducer cannula, the composite tissue marker comprising: an elongate flexible non-bioabsorbable polyvinyl alcohol marker portion having an exterior; anda rigid non-bioabsorbable metallic marker portion secured to the elongate flexible non-bioabsorbable polyvinyl alcohol marker portion with direct contact between the rigid metallic non-bioabsorbable marker portion and the exterior of the elongate flexible non-bioabsorbable polyvinyl alcohol marker portion,wherein the rigid non-bioabsorbable metallic portion is a metal wire having a first end, a second end, and a mid-portion, the metal wire being configured to have a loop at the mid-portion, and with the elongate flexible non-bioabsorbable polyvinyl alcohol marker portion being securely received within the loop.
