Abstract
Electroactive pores, devices including one or more electroactive pores are described, and methods of delivering therapeutic agents using one or more electroactive pores are described.
Claims24
A device, comprising:
- a member having a pore passing therethrough;
- an electroactive polymer disposed so that when the electroactive polymer has a first state of charge a therapeutic agent has a first ability to pass through the pore, and when the electroactive pore has a second state of charge different from the first state of charge the therapeutic agent has a second ability to pass through the pore different than the first ability to pass through the pore;
- and
- a BETA associated with the electroactive polymer.

A method of administering a therapeutic agent, comprising:
- passing the therapeutic agent through a device, comprising:
- a layer of a material having a pore passing therethrough;
- an electroactive polymer disposed so that when the electroactive polymer has a first state of charge a therapeutic agent has a first ability to pass through the pore, and when the electroactive pore has a second state of charge different from the first state of charge the therapeutic agent has a second ability to pass through the pore different than the first ability to pass through the pore;
- and
- a BETA associated with the electroactive polymer.
2 more elements
A method of administering a therapeutic agent, comprising:
- charging an electroactive polymer, the electroactive pore being disposed relative to a pore so that when the electroactive polymer has a first state of charge the therapeutic agent has a first ability to pass through the pore, and when the electroactive pore has a second state of charge different from the first state of charge the therapeutic agent has a second ability to pass through the pore different than the first ability to pass through the pore;
- and
- passing the therapeutic agent through the pore.
