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 (13)

1. A site marker, comprising:

a generally hollow, bioabsorbable body portion having a substantially closed configuration that defines a cavity therein;

a filament secured to an end of said body portion; and

at least one marker element located within the cavity, wherein said filament is secured to said marker element, thereby limiting migration of said marker element.

2. The site marker of claim 1 , wherein said filament is formed into a loop that is received within a through hole formed through said at least one marker element.

3. The site marker of claim 1 , wherein said filament has a predetermined length such that said at least one marker element is retained closer to one end of said body portion.

4. The site marker of claim 1 , wherein said bioabsorbable material is one of polyglycolic acid, polylactic acid, hydrogel, and collagen-based material.

5. The site marker of claim 1 , wherein said body portion is absorbed by a mammalian body after a predetermined time period.

6. The site marker of claim 1 , wherein said at least one marker element is permanent and not bioabsorbable.

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

8. The site marker of claim 1 , wherein said filament extends through said at least one marker element.

9. The site marker of claim 1 , further comprising a deployment line that extends through said at least one marker element.

10. The site marker of claim 9 , wherein the deployment line is secured to a first end of the body portion and is configured to alter the length between the first end and a second end of the body portion to change the site marker from a pre-deployment configuration to a post-deployment configuration.
