ABSTRACT:
Disclosed herein is a catheter device for use in a biological conduit. The catheter device has a catheter body with a housing and a torque cable lumen, a torque cable, a work element, and a connector. The housing is flexible. The torque cable extends through the catheter body to the housing via the torque cable lumen and is capable of rotation and translation with respect to the catheter body. The work element is slidably positioned in the housing. The housing has an interior which guides the work element in response to rotation and translation of the torque cable. The connector attaches the work element to the torque cable. The connector is flexible to facilitate flexion between the work element and the torque cable when the housing flexes.
