More Information
Summary:A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A pivot joint may be used to pivotally connect the distal separator end to the distal shaft portion. The distal shaft portion may comprise a distally-facing transition surface at a proximal end of the distal shaft portion. First and second energizable tissue separator elements may be used at the transition surface and the tip of the device, respectively.
