Abstract: A catheter comprising an elongate tubular member having a proximal end, a distal end, and a passageway defining a lumen extending between the proximal and distal ends. The elongate tubular member comprises a relatively stiff proximal section and a relatively flexible distal section. The proximal section includes an inner tubular liner, a first stiffener comprising a metal alloy, and a second stiffener comprising a non-metal alloy. The first and second stiffeners are coaxially wound exterior to the proximal inner liner. The distal section includes a distal inner tubular liner and the second stiffener coaxially wound exterior to the distal inner liner. The first stiffener terminates before reaching the distal section.

Abstract: 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.
