Abstract

A site marker is provided that includes a generally hollow body defining a cavity. A deployment line within the site marker positions at least one marker element within the body portion. The deployment line has a first end that is fixedly secured to a first end of the body portion and a second end that is secured to a second end of the body portion. The deployment line is pre-biased so as to pull the first end of the body portion towards the second end of the body portion, and thereby expand the body portion.

Claims (18)

1. A site marker, comprising:

a generally hollow body portion that defines a closed cavity therein;

a deployment line; and

at least one marker element disposed within said cavity of said body portion such that said marker element may move within said cavity;

wherein said deployment line has a first end fixedly secured to a first end of said body portion and a second end fixedly secured to a second end of said body portion, said deployment line being pre-biased so as to pull said first end of said body portion toward said second end of said body portion, thereby expanding said body portion.

2. The site marker of claim 1 , wherein said hollow body portion is constructed of a bioabsorbable material.

3. The site marker of claim 2 , wherein said bioabsorbable material is one of polyglycolic acid, polylactic acid, hydrogel, and collagen-based material.

4. The site marker of claim 2 , wherein said body portion is absorbed by a mammalian body after a predetermined time period.

5. The site marker of claim 4 , wherein said predetermined time period is in the range of about three weeks to six months.

6. The site marker of claim 2 , wherein said marker element is permanent such that said marker element is not bioabsorbable.

7. The site marker of claim 6 , wherein said marker element is visible under multiple imaging modalities.

8. The site marker of claim 1 , wherein said marker element has a through opening that receives said deployment line therethrough, thereby limiting migration of said marker element.

9. The site marker of claim 8 , wherein said marker element is able to slide along said deployment line.

10. The site marker of claim 8 , wherein said marker element is one of a tube, ring, and helical member.

11. The site marker of claim 8 , further including a retaining filament secured to one end of said ends of said body portion, wherein said retaining filament operates to retain said marker element.

12. The site marker of claim 11 , wherein the retaining filament is formed into a loop that is secured around a portion of said marker element.

13. The site marker of claim 1 , wherein said deployment line is a hollow tube.

14. The site marker of claim 13 , wherein said marker element has a smaller outside periphery than the inner circumference of said hollow deployment line, such that said marker element may be inserted inside of said hollow deployment line.
