Catheter systems with interchangeable parts

摘要

A catheter system having a changeable distal member. The catheter system includes a proximal member, including a shaft having a proximal end, a distal end and a lumen extending therethrough. A distal member is included having a distal portion which may be passed through the lumen of the proximal member and releasably sealed to the proximal member at a desired location during a catheter procedure. The distal member may further include a push member operably coupled to the distal portion. The distal member may include a fluid-tight releasable seal for releasably sealing the distal member to the proximal member.
