Catheter for manual and remote manipulation

An elongate medical device comprising:

• a modular cartridge comprising:
• a housing;
• a shaft having a distal portion and a proximal portion, said proximal portion coupled with said housing;
• a pull wire extending through said shaft and coupled with said distal portion of said shaft;
• and
• an interface member movably disposed within said housing, said interface member coupled with said pull wire such that movement of said interface member results in movement of said pull wire;
• and
• a handle portion releasably coupled to said modular cartridge, comprising:
• a receiving member releasably coupled with said interface member;
• and
• an actuation mechanism configured for manual manipulation, coupled with said receiving member, configured to impart force to said pull wire through said receiving member so as to deflect the distal portion of said shaft.

An elongate medical device comprising:

• a shaft having a proximal portion and a distal portion;
• a pull wire disposed in said shaft and affixed to said distal portion of said shaft;
• and
• a handle having a distal end and a proximal end, said distal end coupled with the proximal portion of said shaft, said proximal end comprising an interface for coupling with a remote catheter guidance system, said interface comprising at least one electrical connector, a fluid port, a mechanical interlock, and an apparatus for actuating said pull wire so as to deflect said distal portion of said shaft.
