摘要：
An example system for sensing catheter contact is disclosed. The system includes an elongate tubular member, a tip member and a flexible support structure including a support member. A proximal portion of the support structure may be coupled to the distal end of the tubular member while a distal portion may be coupled to the proximal end of the tip member. The system may also include an electroactive polymer member disposed along the support member, wherein displacement of the support member activates the electroactive polymer member such that an electrical response is output from the electroactive polymer member. A processor, electrically coupled to the electroactive polymer member, may be configured to evaluate the electrical response from the electroactive polymer member to determine a contact force of the tip member with tissue.
