Claim Text:
1. A delivery device for delivering material into a catheter through a catheter port, the delivery device comprising: a cannula having a generally tubular shape and a distal end; a stability collet having a distal attachment portion configured to attach the stability collet to a catheter port and a longitudinal channel through which the cannula extends, the longitudinal channel being dimensioned to allow a longitudinal movement of the cannula in the longitudinal channel; and an elastic member acting between the cannula and the stability collet, the elastic member biasing the cannula distally relative to the stability collet, the elastic member having a relaxed state absent from external forces while inside the stability collet and a tensioned state, the relaxed state positioning the distal end of the cannula distally from the tensioned state.
