Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
42 words
A process for delivering therapeutric or diagnostic reagents directly to the lymphatics comprising the steps of: (1) inserting an endoscope into a body passage or cavity, and (2) administering the reagent through the endoscope into tissues for uptake by the lymphatic vessels.
Claim 2
Dependent Claim
42 words

Claim 3
Dependent Claim
65 words
A process according to claim 1 for delivering a composition containing therapeutic and/or diagnostic reagents to tissues for uptake by lymphatic vessles comprising the steps of: (1) inserting an endoscope into a body passage or cavity in the location of tissues near the terminal lymphatic vessels, and (2) administering the composition by injection into tissues in the area of the terminus of the lymphatic vessels.
