Abstract
A deflectable catheter assembly having a compression compensation mechanism is disclosed. The deflectable catheter assembly comprises a catheter shaft having a catheter proximal section and a catheter distal section. A therapeutic tool is disposed within the catheter shaft. A compression compensation mechanism is coupled to the therapeutic tool to compensate for a length change in the catheter shaft such as when the catheter shaft is deflected. The compression compensation mechanism includes a spring moveably disposed between a distal stop and a proximal stop that are attached to the therapeutic tool. A deployment slide is moveably disposed proximate to the spring and between the distal stop and the proximal stop. A catheter handle configured to house the compression compensation mechanism is coupled to the catheter shaft.
