Abstract
A catheter assembly has an engaged state and an unengaged state comprising a proximal member having a longitudinal axis and a distal member having a longitudinal axis. A distal end of the proximal member is removably engageable to the distal member. The distal member has a first distal portion and a second distal portion, and the first distal portion is retractable from the second distal portion. In the engaged state the distal member is substantially freely rotatable about its longitudinal axis and in relation to the proximal member. In the engaged state the proximal member is constructed and arranged to be moved in a direction along the longitudinal axis such that proximal movement of the proximal member retracts at least the first distal portion of the distal member from at least the second distal portion.
