A catheter assembly for an ultrasound system can include an integrated pullback arrangement. For example, the catheter assembly can include a telescoping pullback section having a first telescope, a second telescope, a distal grip coupling one of the first or second telescope to the distal sheath of the distal section, and a proximal grip coupled to another of the first or second telescope so that the first telescope can be retracted into the second telescope and a sensor to determine a position of the first telescope. Another example includes the sensor and a pullback slider arrangement having a housing defining a slit, a coupler disposed within the housing, and a slider handle extending through the slit and coupled to the coupler. In another example, the coupler and housing can be gripped and slid relative to each other. |
