Catheter for manual and remote manipulation
First Claim
1. 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 and said proximal end opposite said distal end, said handle comprising;
a first mechanism configured for manual actuation of said pull wire so as to deflect the distal portion of said shaft;
a second mechanism configured for remote actuation of said pull wire so as to deflect the distal portion of said shaft; and
a mechanical interface disposed at said proximal end of said handle and configured to provide a remote system with a functional connection to said second mechanism.

Abstract
An elongate medical device may overcome be configured both for manual manipulation by a physician and for automatic manipulation by a remote catheter guidance system. Such an elongate medical device comprises a shaft having a proximal portion and a distal portion, a pull wire disposed in the shaft and affixed to the distal portion of the shaft, and a handle coupled with the proximal portion of the catheter shaft. The handle comprises a first mechanism configured for manual actuation of the pull wire so as to deflect the distal portion of the shaft, a second mechanism configured for remote actuation of the pull wire so as to deflect the distal portion of the shaft, and a mechanical interface configured to provide a remote catheter guidance system with a functional connection to the second mechanism.

13. 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; a connection interface comprising at least one electrical connection; 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. - View Dependent Claims (14, 15, 16, 17, 18)
