Abstract

A catheter system is provided. The system includes a catheter having an elongated flexible body and one or more electroactive polymer actuators disposed along the elongated flexible body. The electroactive polymer actuators are adapted to cause a change in configuration of the elongated flexible body. The system also includes a controller adapted to transmit the control signal to the electroactive polymer actuators. The controller includes a memory storing a plurality of control signals corresponding to a plurality of predetermined configurations of the catheter and a user-interface coupled to the memory. The user-interface is configured to select one or more configurations from the plurality of predetermined configurations in response to user input.

a memory storing a plurality of control signals corresponding to a plurality of predetermined configurations of the catheter; and
a user-interface coupled to the memory and configured to receive user input selecting an anatomical structure type from a plurality of predetermined anatomical structure types stored in the memory,
wherein the controller is configured to select at least one configuration from the plurality of predetermined configurations based on the user input selecting the anatomical structure type from the plurality of predetermined anatomical structure types.

2. The catheter system according to claim 1 , wherein the user-interface includes a voice control module.

3. The catheter system according to claim 2 , wherein the voice control module includes a microphone and a speech-recognition engine.

4. The catheter system according to claim 3 , wherein the speech-recognition engine is configured to detect voice input and to match the voice input to at least one command associated with the at least one configuration, the user input selecting the anatomical structure type from the plurality of predetermined anatomical structure types comprising the voice input.

5. The catheter system according to claim 4 , wherein the at least one command is associated with a change in the configuration of the elongated flexible body and is selected from a group consisting of at least one of a blood vessel configuration, a neurovascular formation, or an anatomical malformation.

6. The catheter system according to claim 4 , wherein the at least one command corresponds to the anatomical structure type and the at least one configuration corresponds to a shape of the catheter for conforming to an anatomical structure of the anatomical structure type.

7. The system of claim 1 , wherein the controller further comprises a processing unit, and wherein the user interface is configured to determine a command based on the user input and the processing unit is configured to receive the command and select the at least one configuration based on the command.

8. The system of claim 1 , further comprising a steering control module, wherein the controller is configured to select the at least one configuration by at least causing the steering control module to generate one or more control signals that results in adjustment of the at least one electroactive polymer actuator to conform the catheter to the selected at least one configuration.

9. The system of claim 1 , wherein the at least one configuration is selected to conform the catheter to an anatomical structure of the anatomical structure type in response to the at least one command.

10. The system according to claim 1 , wherein the anatomical structure type comprises at least one of: a blood vessel configuration type, a neurovascular formation type, or an anatomical malformation type.

11. A method for controlling a catheter for accessing a body lumen, the method comprising:
