Abstract
Apparatus, systems, and methods for delivery of an automatically clearing composition in a balloon.
Claims18
A system for delivery of an automatically clearing fluid composition, comprising:
- a balloon that contains a colorant and a redox potentiating agent, the colorant having a first redox state in which the colorant is colored, and a second redox state in which the colorant is clear, and the redox potentiating agent comprising a compound effective to change the colorant from the first redox state to the second redox state;
- and
- at least one of the colorant and the redox potentiating agent disposed within at least one vesicle, the colorant and the redox potentiating agent and thus the at least one vesicle all being contained within the balloon, whereby only upon bursting the balloon and the at least one vesicle as by the balloon striking a target are the colorant and the redox potentiating agent released so that the colorant in the first redox state marks the target and interacts with the redox potentiating agent to subsequently change from the first redox state to the second redox state.
A system for delivery of an automatically clearing fluid composition, comprising:
- a balloon that contains a colorant and a redox potentiating agent, the colorant having a first redox state in which the colorant has an optical density of greater than 0.5, and a second redox state in which the colorant has an optical density of less than 0.1, and the redox potentiating agent comprising a compound effective to change the colorant from the first redox state to the second redox state, the redox potentiating agent selected from the group consisting of an oxidizing agent and a reducing agent;
- and
- at least one of the colorant and the redox potentiating agent disposed as a coating on an inside surface of the balloon, whereby only upon bursting the balloon as by the balloon striking a target do the colorant and the redox potentiating agent interact to change from the first redox state to the second redox state.
