Claim:
1. A modular catheter assembly, including: a holder having an axially extending bore, a proximal end and a distal end, wherein the holder includes a control mechanism being axially displaceably arranged on the holder and being accessible externally of the holder, wherein the control mechanism comprises a first receiving formation, wherein the holder comprises a second receiving formation at the proximal end of the holder, the first receiving formation comprising a first locking mechanism and the second receiving formation comprising a second locking mechanism; an electrode sheath carrier mounted on the distal end of the holder; a shape-imparting element carrier including a first engaging formation and a second engaging formation, wherein the first engaging formation and the first receiving formation and the second engaging formation and the second receiving formation are cooperatively configured for de-attachment and re-attachment of the shape-imparting element carrier with the control mechanism by operation of the first and second locking mechanisms, the first and second locking mechanisms operable by joint rotation of the first engaging formation and the second engaging formation of the shape-imparting element carrier relative to the holder, the shape-imparting element carrier configured to be unlocked from the holder by joint rotation of the first engaging formation and the second engaging formation of the shape-imparting element carrier relative to the holder; and a shape-imparting element carried on the shape-imparting element carrier, the shape-imparting element comprising an elongate tubular member extending outwardly from the distal end of the holder when the shape-imparting element carrier is attached with the holder, wherein the elongate tubular member is coupled to the shape-imparting element carrier and configured for removal from the holder with the shape-imparting element carrier when the shape-imparting element carrier and the control mechanism are de-attached, the elongate tubular member and the shape-imparting element carrier remaining coupled while the shape-imparting element carrier is de-attached from the control mechanism.
