Claims
- 1. A method for marking a bodily site in a patient comprising the steps of:
identifying the bodily site; and positioning a pledget of absorbable sponge material adjacent the bodily site wherein the absorbable sponge material includes a contrasting agent.
- 2. The method of claim 1 wherein the contrasting agent is water insoluble.
- 3. The method of claim 2 wherein the contrasting agent is selected from the group consisting of tantalum, tantalum oxide, barium sulfate, gold, tungsten, and platinum and mixtures thereof.
- 4. The method of claim 1 wherein the contrasting agent is water soluble.
- 5. The method of claim 4 wherein the contrasting agent is selected from the group consisting of metrizamide, iopamidol, iothalamate sodium, iodomide sodium, and meglumine and mixtures thereof.
- 6. The method of claim 1 wherein the sponge material comprises a gelatin based sponge.
- 7. The method for performing a biopsy comprising the steps of:
removing tissue from a vascular tissue site; and positioning a pledget of absorbable sponge material adjacent the vascular tissue site wherein the absorbable sponge material includes a contrasting agent.
- 8. The method of claim 7 wherein the contrasting agent is water insoluble.
- 9. The method of claim 8 wherein the contrasting agent is selected from the group consisting of tantalum, tantalum oxide, barium, sulfate, gold, tungsten, and platinum and mixtures thereof.
- 10. The method of claim 7 wherein the contrasting agent is water soluble.
- 11. The method of claim 10 wherein the contrasting agent is selected from the group consisting of metrizamide, iopamidol, iothalamate sodium, iodomide sodium, and meglumine and mixtures thereof.
- 12. A liquid permeable, absorbable gelatin sponge that is prepared by a process that comprises the steps of:
(a) preparing an aqueous gelatin solution; (b) adding an organic solvent in the aqueous gelatin solution to form a second solution; (c) incubating the second solution; (d) forming a foam from the second solution wherein a contrasting agent is added to the second solution at any step prior to forming the foam; and (e) drying the foam.
- 13. The gelatin sponge of claim 12 wherein step (d) comprises whipping the second solution until a foam is produced.
