Abstract
The present invention relates to different methods of delineating target tissue from non-target tissue using differences in radiographic properties of a medical device.
Claims16
A method for localizing target tissue in a patient, comprising:
- (a) surgically resecting at least a portion of the target tissue and thereby creating a resection cavity comprising a target volume;
- (b) applying an amount of a negative contrast agent to said resection cavity such that said target volume is filled with said a bioabsorbable negative contrast agent;
- and (c) localizing the target tissue by visualizing the negative contrast agent in three dimensions, and (d) applying the external radiation treatment to said target tissue.
A method for localizing target tissue in a patient, comprising:
- (a) applying an amount of a negative contrast agent to a body cavity such that said cavity is filled with said negative contrast agent;
- (b) localizing a target tissue by visualizing the negative contrast agent in three dimensions wherein said target tissue is proximate to said cavity, and (d) applying the external radiation treatment to said target tissue.
A method for localizing target tissue in a patient, comprising:
- (a) applying an amount of a negative contrast agent to a body cavity such that said cavity is filled with said negative contrast agent;
- (b) localizing the target tissue by visualizing the negative contrast agent in three dimensions, and (d) applying radiation treatment to said target tissue.
A method for treating a proliferative tissue disorder, comprising:
- (a) surgically resecting at least a portion of the proliferative tissue and thereby creating a resection cavity;
- (b) providing a tissue fixation device having an expandable surface sized and configured to reproducibly position tissue surrounding the resection cavity in a predetermined geometry upon expansion of the expandable surface into an expanded position and wherein said expandable surface is comprised of metal or a metal matrix;
- (c) positioning the tissue fixation device so that the expandable surface is within the resection cavity;
- (d)
- expanding the expandable surface to position the tissue surrounding the resection cavity in the predetermined geometry;
- and (e) applying an external radiation treatment to the tissue surrounding the resection cavity.
